Planting method of tomato intercropping with allium mongolicum using brackish water irrigation

Abstract

The present invention provides a method for intercropping tomatoes with Allium mongolicum using brackish water irrigation. The method of appropriately irrigating tomatoes with brackish water can improve tomato quality, maintain yield, and increase efficiency. Furthermore, the present invention employs a method of intercropping Allium mongolicum between tomato rows, which not only improves the physical and chemical properties of the tomato rhizosphere soil and increases the microbial diversity of the tomato rhizosphere soil, but also enhances the vitality of the tomato root system. Furthermore, intercropping Allium mongolicum between tomato rows can improve tomato growth and coincide with the peak fruiting period of tomatoes with the flowering period of Allium mongolicum. During the peak fruiting period, the adhesion strength of tomato fruit pedicles can be increased, reducing the risk of tomatoes falling due to natural factors such as their own weight. Practice has shown that intercropping Allium mongolicum between tomato rows can improve tomato yield and quality, with tomato yields reaching up to 2,710 kg / mu, while also preventing root rot and root rot in tomatoes.

Description

Technical Field

[0001] The present application belongs to the field of brackish water irrigation technology, and in particular relates to a method for planting tomatoes and intercropping alliums with brackish water irrigation. Background Art

[0002] Tomatoes are annual or perennial plants of the Solanaceae family, growing 0.6 to 2 meters tall. They are covered with sticky glandular hairs and have a strong odor. Their stems are prone to lodging. Their leaves are pinnate or deeply pinnately lobed. Their inflorescences have peduncles 2-5 cm long. Their calyx and corolla are radiate, and their berries are oblate or nearly globose, fleshy and juicy. Their seeds are yellow, and they flower and fruit in summer and autumn. Originating in South America, tomatoes are widely cultivated in both northern and southern China. The berries are highly nutritious and have a unique flavor. They can be eaten raw, cooked, processed into tomato sauces, juice, or canned whole.

[0003] Tomatoes are generally planted in spring, and the planting time varies in each region. The southern region can generally choose March, and the northern region can choose April to May. The temperature should be stable during planting. Tomatoes are an important vegetable crop in my country and have strong salt tolerance. Moderate irrigation with brackish water can improve the quality of tomatoes and ensure yield and increase efficiency. However, due to the large amount of salt ions in brackish water, improper irrigation will cause the soil salt content to increase. Saline-alkali soil will cause the soil permeability to decrease. During the planting process, the roots of tomatoes need weeds to promote the growth of tomatoes. Reduced soil permeability will lead to a decrease in oxygen in the soil, but the weed roots need sufficient oxygen for aerobic respiration to maintain their own metabolism and the growth and development of the entire plant. Therefore, reduced soil permeability will cause the weeds to wither and die. Therefore, as brackish water is used for irrigation during tomato cultivation, salt will accumulate in the soil, increasing the salt content in the soil and changing the growth environment of weeds at the roots of tomatoes. Soil with a higher salt content is not conducive to the growth of weeds, which will cause the weeds at the roots of tomatoes to fail to grow normally and gradually wither and die, leading to root rot at the roots of tomatoes, which can easily cause root damage. Summary of the Invention

[0004] Based on this, the present invention provides a method for planting tomatoes intercropped with mongolica using brackish water irrigation, so as to solve the technical problem in the prior art that as tomatoes are continuously irrigated with brackish water, excessive salt accumulates, causing the weeds at the roots of the tomatoes to change and fail to grow normally, resulting in root rot and easy root damage.

[0005] The technical solution of the present invention to solve the above technical problems is as follows:

[0006] A method for planting tomatoes and intercropping alliums using brackish water irrigation comprises the following steps:

[0007] S10 Planting tomatoes: Ridges were formed in the experimental field with a ridge width of 20 cm to 25 cm and a ridge height of 20 cm to 30 cm.

During the peak fruiting period of tomatoes, drip irrigation with brackish water is applied to each plant every 4 to 6 days. Harvest shallots 30 days before the peak fruiting period of tomatoes to control the flowering period of shallots and make the flowering period of shallots coincide with the peak fruiting period of tomatoes.

[0011] Preferably, in step S20, the salt content of the brackish water is 0.5% to 0.8%.

[0012] Preferably, in step S20, the layout of the brackish water irrigation system includes: setting the main pipe perpendicular to the ridge at one end of the ridge, connecting several branch pipes vertically to the main pipe, and setting a branch pipe on each ridge, and laying the branch pipes along the ridge, and providing drip irrigation heads at intervals of 15 cm to 20 cm on the branch pipes, and each tomato seedling root corresponds to a drip irrigation head, and the drip irrigation head is located under the membrane.

[0013] Preferably, in step S30, the planted shallot is transplanted between any two adjacent tomato roots by using a root division method.

[0014] Preferably, in step S30, the distance between the tomato and the shallot is 5 cm to 10 cm.

[0015] Preferably, in step S40, the mongolica is harvested at intervals of 15 to 20 days during the initial flowering and fruiting periods of tomatoes to prevent the mongolica from flowering and setting seeds. The mongolica is finally harvested 30 days before the peak fruiting period of tomatoes to control the flowering period of the mongolica.

[0016] Preferably, in step S40, during the initial flowering period of tomatoes, each plant is drip-irrigated with a fixed amount of brackish water every 3 to 5 days, and the drip irrigation time is 1 to 2 hours. During the fruiting period of tomatoes, each plant is drip-irrigated with a fixed amount of brackish water every 4 to 9 days, and the drip irrigation time is 4 to 5.5 hours.

BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 The present invention is a structural diagram of a method for planting tomatoes and intercropping alliums with brackish water irrigation.

[0023] In the picture: main pipe 100, branch pipe 200, drip irrigation head 300, tomatoes 400, and shallots 500. DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the embodiments.

[0025] A method for planting 400 tomatoes and 500 shallots using brackish water for irrigation, comprising the following steps:

[0026] S10 Planting of Tomato 400: Ridges were made in the experimental field with a ridge width of 20cm to 25cm and a ridge height of 20cm to 30cm. Film was covered after ridge making. After covering with film, tomato 400 seedlings were planted on the ridges at intervals of 15cm to 20cm. The growth cycle of tomato 400 is 4 to 6 months.

[0027] Specifically, after ridge formation, cover the ridges with film. When covering, align both sides and tighten the film. Cover and compact the soil along the slope of the ridges on both sides, pressing the soil horizontally at intervals of 1.3m to 2.5m. After covering with film, plant seedlings on the ridges. The 400 tomato seedlings planted on the ridges are for transplanting. Select strong seedlings of the appropriate seedling age for transplanting. The selected seedlings should have uniform overall growth, a well-developed root system, a light purple base of the stem, a green upper part, a dark green leaf color, thick leaves, and no disease spots, bacterial or viral infections. Plant two rows of 400 tomatoes per ridge during planting. After transplanting, promptly add soil to ensure that the roots are in full contact with the soil and prevent damage caused by severe weather such as strong winds. The growth cycle of Tomato 400 is 4 to 6 months. The development period of Tomato 400 is generally 7 to 9 days. Under suitable temperature, seedlings generally need about 50 days, 60 to 80 days in cold season, and about 40 days in high temperature season; the flowering and fruiting period takes 15-30 days, and the time is short for early maturity or high temperature cultivation, and long otherwise; the fruit of Tomato 400 begins to swell 3 to 4 days after flowering and pollination, and will swell to its limit after 7 to 20 days, or as fast as 30 days, and begins to color and reach maturity after 40 to 50 days.

[0028] S20 is equipped with a brackish water irrigation system, using brackish water for drip irrigation.

[0029] Specifically, the layout of the brackish water irrigation system includes: setting the main pipe 100 perpendicular to the ridge at one end of the ridge, connecting several branch pipes 200 vertically to the main pipe 100, and setting a branch pipe 200 on each ridge, and the branch pipes 200 are laid along the ridge, and drip irrigation heads 300 are opened on the branch pipes 200 at intervals of 15 cm to 20 cm. There is a drip irrigation head 300 corresponding to the root of each tomato seedling 400, and the drip irrigation head 300 is located under the film.

[0030] The drip irrigation system consists of a header hub, pipelines and drip heads 300. The header hub includes a water pump (and power machine), a fertilizer tank, a filter, and control and measuring instruments. The pipeline includes a main pipe 100, branches and necessary regulating equipment. The water pump is connected to the main pipe 100. The main pipe 100 is set at one end of the ridge perpendicular to the ridge and arranged along the edge of the field. The main pipe 100 is vertically connected to 2-6 branch pipes 200. The drip irrigation belt is laid along the planting direction of the tomatoes 400. Near the roots of the tomatoes 400, a drip irrigation belt is laid in each row. The drip irrigation belt is equipped with a drip irrigation head 300. Turn on the water pump to pump water and send a certain amount of pressure water into the main pipe 100, which is then transported to each branch pipe 200 through the main pipe 100 to irrigate the tomato seedlings 400 through the drip irrigation heads 300 to ensure that every root system of the tomato 400 is irrigated.

[0031] Preferably, the brackish water has a salt content of 0.5% to 0.8%.

[0032] S30 Planting of Allium 500: Interplant Allium 500 seedlings between the roots of any two adjacent tomatoes 400.

[0033] Specifically, the planted shallots 500 are transplanted between the roots of any two adjacent tomatoes 400 using the root division method. Specifically, the shallots 500 are transplanted between the roots of any two adjacent tomatoes 400 to the same ridge where the tomatoes 400 are planted. Preferably, the distance between the tomatoes 400 and the shallots 500 is 5 cm to 10 cm. Specifically, if the distance between the shallots 500 and the tomatoes 400 is too close, the shallots 500 and the tomatoes 400 will compete for fertilizer, light, water, space, etc. It absorbs the nutrients of tomato 400, affects the normal growth of tomato 400, and reduces the yield and quality of tomato 400; if the distance between shallot 500 and tomato 400 is too far, the soil with a high salt content is not conducive to the growth of weeds, which causes the weeds at the roots of tomato 400 to fail to grow normally and gradually wither and die. The distance between shallot 500 and tomato 400 is too far, which cannot promote the growth of the roots of tomato 400, thereby causing root rot at the roots of tomato 400 and easily causing root damage.

[0034] S40 flowering period management: Tomato 400 and Allium 500 were managed according to conventional agronomic measures. During the initial flowering period of Tomato 400, each plant was drip-irrigated with slightly brackish water every 3 to 5 days. During the fruit setting period of Tomato 400, each plant was drip-irrigated with slightly brackish water every 4 to 9 days. During the peak fruiting period of Tomato 400, each plant was drip-irrigated with slightly brackish water every 4 to 6 days. 30 days before the peak fruiting period of Tomato 400, Allium 500 was harvested to control the flowering period of Allium 500 and make the flowering period of Allium 500 coincide with the peak fruiting period of Tomato 400.

[0035] Specifically, during the initial flowering period of Tomato 400, each plant is drip-irrigated with slightly brackish water every 3 to 5 days, and the drip irrigation time is 1 to 2 hours. During the fruit-setting period of Tomato 400, each plant is drip-irrigated with slightly brackish water every 4 to 9 days, and the drip irrigation time is 4 to 5.5 hours. During the peak fruit-bearing period of Tomato 400, each plant is drip-irrigated with slightly brackish water every 4 to 6 days, and the drip irrigation time is 1.5 to 3 hours. During the initial flowering and fruit setting period of Tomato 400, Allium 500 is harvested every 15 to 20 days. Harvesting Allium 500 is beneficial to the growth of Allium 500 on the one hand, and on the other hand, it prevents Allium 500 from flowering and seeding, which would collide with the flowering period of Tomato 400. Allium 500 is harvested for the last time 30 days before the peak fruiting period of Tomato 400 to control the flowering period of Allium 500. After harvesting, when Allium 500 blooms again, it will coincide with the peak fruiting period of Tomato 400.

[0036] Practice has shown that properly irrigating tomatoes with brackish water can improve their quality, maintain yield, and increase efficiency. Furthermore, the present invention's method of intercropping Allium mongolicum (Schizonepeta spp.) between tomato rows not only improves the physical and chemical properties of the rhizosphere soil and increases the microbial diversity of the rhizosphere soil, but also enhances root vitality and prevents root rot. Furthermore, intercropping Allium mongolicum (Schizonepeta spp.) between tomato rows improves the growth of tomatoes, aligning their peak fruiting period with their flowering period. This increases the cohesive strength of tomato pedicles during the peak fruiting period and reduces the risk of tomatoes falling due to natural factors such as their own weight. Practice has shown that intercropping Allium mongolicum (Schizonepeta spp.) between tomato rows can improve both tomato yield and quality, with yields reaching as high as 2710 kg / mu.

[0037] In a specific preferred embodiment, the following steps are also included:

[0038] After the peak fruiting period of S50 tomatoes 400, tomatoes 400 are harvested and mature seeds of allium 500 are harvested.

[0039] After the tomatoes 400 mature, the mature tomatoes 400 are picked, and the mature seeds of the shallot 500 are harvested at the same time for planting the following year.

[0040] In a specific preferred embodiment, the method further includes fertilizing the tomatoes 400 and the shallots 500, wherein the fertilizer is organic fertilizer (made from decomposed feces, compost, cake fertilizer, grass ash, and straw).

[0041] Specifically, fertilize Tomato 400 and Allium 500 with organic fertilizers, including urea, superphosphate, potassium sulfate, zinc sulfate, and triple compound fertilizers. Organic fertilizers made from manure, compost, cake fertilizer, grass ash, and decomposed straw can also be used. Fertilize Tomato 400 and Allium 500 before planting, and apply topdressing after planting.

[0042] The following experimental process further illustrates the technical effects brought about by the technical solution of the present invention.

[0079] Comparative Example 8

[0083] Table 2

[0084]

[0085] Note: (1) “Overlap” means whether the flowering period of Allium mongolicum 500 coincides with the peak fruiting period of Tomato 400.

[0086] (2) The judgment rules for “overlap” are as follows: when the flowering period of Allium 500 is completely staggered with the peak fruiting period of Tomato 400 / the number of overlapping days is less than or equal to 3 days, it is “no overlap”; when the flowering period of Allium 500 is overlapping with the peak fruiting period of Tomato 400 for more than 3 days and less than or equal to 8 days, it is “slight overlap”; when the flowering period of Allium 500 is overlapping with the peak fruiting period of Tomato 400 for more than 8 days, it is “overlap”.

[0087] (3) The evaluation rule for “tomato stem adhesion strength” is as follows: within 5 days after the tomato 400 is in its peak fruit-bearing period, count the number of tomatoes N that fall naturally, that is, the number of tomatoes that fall on the ground. At the same time, harvest the mature tomatoes in the experimental field (that is, the mature tomatoes growing on the tomato plants, excluding the tomatoes that fall naturally (fall on the ground)), and count the number of mature tomatoes M. If N / (M+N) ≥ 0.2, it means that the tomato stem adhesion strength is weak; if 0.1 < N / (M+N) < 0.2, it means that the tomato stem adhesion strength is slightly strong; if N / (M+N) ≤ 0.1, it means that the tomato stem adhesion strength is strong.

[0088] Comparative Example 10

[0089] Same as Comparative Example 5, except that the brackish water was changed to normal water.

[0090] Comparative Example 11

[0091] Same as Comparative Example 6, except that the brackish water was replaced with normal water.

[0092] Comparative Example 12

[0093] Same as Comparative Example 7, except that the brackish water was replaced with normal water.

[0094] Comparative Example 13

[0096] Comparative Example 14

[0097] Same as Comparative Example 9, except that the brackish water was replaced with normal water.

[0098] Table 3

[0099]

[0100] Through (Comparative Example 1, Comparative Example 2), this set of examples shows that the use of normal water to irrigate tomatoes 400 and interplanting allium 500 has a small effect on the yield of tomatoes 400, and the yields of tomatoes 400 are 2360 kg / mu and 2377 kg / mu respectively; through (Example 1, Example 2) this set of experimental examples shows that when allium 500 is not interplanted, and only brackish water is used to irrigate tomatoes 400, the yield of tomatoes 400 begins to rise, reaching 2461 kg / mu. When brackish water is used to irrigate tomatoes 400 and allium 500 is interplanted in Example 2, the yield of tomatoes 400 reaches 2522 kg / mu. It can be seen from the yield of tomatoes 400 in the above comparative examples and examples that the use of brackish water to irrigate tomatoes 400 and interplant allium 500 will have a certain impact on the yield of tomatoes 400, and when brackish water is used to irrigate tomatoes 400 and interplant allium 500, the yield of tomatoes 400 is higher. Compared with using normal water to irrigate tomatoes 400 and interplanting allium 500, when using slightly saline water to irrigate tomatoes 400 and interplanting allium 500, the yield of tomatoes 400 increased by at least 4.5%; compared with using slightly saline water to irrigate but not interplanting allium 500, when using slightly saline water to irrigate tomatoes 400 and interplanting allium 500, the yield of tomatoes 400 increased by at least 2%.

[0101] Through Examples 2, 3, and 4, it can be seen that when using brackish water to irrigate tomatoes 400, the salt content of the brackish water also has a certain impact on the yield of tomatoes 400. In Example 2, the yield of tomatoes 400 was 2522 kg / mu, in Example 3, the yield of tomatoes 400 was 2710 kg / mu, and in Example 4, the yield of tomatoes 400 was 2638 kg / mu. Compared with Example 2, the yield of tomatoes 400 in Example 4 was increased. The yield of tomatoes 400 in Example 3 was 2710 kg / mu, which was also increased compared with Example 4. The yield of tomatoes 400 in the above examples shows that when using brackish water to irrigate tomatoes 400, the salt content of the brackish water also has a certain impact on the yield of tomatoes 400. When the salt content of brackish water is 0.7%, the yield of tomatoes 400 is higher. Compared with the case where the salinity of brackish water is 0.4%, the yield of Tomato 400 increased by at least 5.5% when the salinity of brackish water is 0.7%; compared with the case where the salinity of brackish water is 0.9%, the yield of Tomato 400 increased by at least 2% when the salinity of brackish water is 0.7%.

[0102] From Examples 5 to 9, it can be seen that harvesting the shallot 500 before the peak fruiting period of the tomato 400 has a certain but not significant effect on the yield of the tomato 400, but has a greater effect on the adhesion strength of the fruit stalks of the tomato 400. In Example 5, the shallot 500 was harvested 15 days before the peak fruiting period of the tomato 400, and the yield of the tomato 400 was 2562 kg / mu. In Example 6, the shallot 500 was harvested 23 days before the peak fruiting period of the tomato 400, and the yield of the tomato 400 was 22587 kg / mu. Compared with Example 5, the yield of the tomato 400 in Example 6 was improved. In Example 7, the shallot 500 was harvested 30 days before the peak fruiting period of the tomato 400, and the yield of the tomato 400 was 22587 kg / mu. The yield of tomato 400 is 2668Kg / mu. In Example 8, the mongolica 500 is harvested 38 days before the peak fruiting period of tomato 400, and the yield of tomato 400 is 2646Kg / mu. Compared with Example 8, the yield of tomato 400 in Example 7 is improved. In Example 9, the mongolica 500 is harvested 46 days before the peak fruiting period of tomato 400, and the yield of tomato 400 is 2626Kg / mu. Compared with Example 9, the yield of tomato 400 in Example 8 is improved.

[0103] In Example 5, the allium 500 was harvested 15 days before the peak fruiting period of the tomato 400. In Example 9, the allium 500 was harvested 46 days before the peak fruiting period of the tomato 400. In Example 6, the allium 500 was harvested 23 days before the peak fruiting period of the tomato 400. In Example 8, the allium 500 was harvested 38 days before the peak fruiting period of the tomato 400. Compared with Example 5 and Example 9, the adhesion strength of the fruit stalks of the tomato 400 in Examples 6 and 8 was stronger. In Example 7, the allium 500 was harvested 30 days before the peak fruiting period of the tomato 400. Compared with Example 6 and Example 8, the adhesion strength of the fruit stalks of the tomato 400 in Example 7 was stronger. In addition, in Example 7, the allium 500 was harvested 30 days before the peak fruiting period of the tomato 400. After harvesting, the flowering period of the allium 500 coincided with the peak fruiting period of the tomato 400. The adhesion strength of tomato 400 fruit stems in the above examples demonstrates that harvesting allium 500 before the peak fruiting period of tomatoes 400 affects the adhesion strength of the tomato 400 fruit stems, and that harvesting allium 500 30 days before the peak fruiting period of tomatoes 400 results in a stronger adhesion strength of the tomato 400 fruit stems. (Whether the flowering period of allium 500 overlaps with the peak fruiting period of tomatoes 400 was determined by harvesting allium 500 15, 23, 30, 38, and 46 days before the peak fruiting period of tomatoes 400 in Examples 5 to 9, and then manually observing the degree of overlap between the flowering period of allium 500 and the peak fruiting period of tomatoes 400.)

[0104] It can be seen from Examples 10 to 14 that even if normal water irrigation is used, harvesting the shallot 500 before the peak fruiting period of the tomato 400 has a certain but not significant effect on the yield of the tomato 400, but has a greater effect on the adhesion strength of the fruit stalks of the tomato 400. In Example 10, the shallot 500 was harvested 15 days before the peak fruiting period of the tomato 400, and the yield of the tomato 400 was 2335 kg / mu. In Example 11, the shallot 500 was harvested 23 days before the peak fruiting period of the tomato 400, and the yield of the tomato 400 was 2355 kg / mu. Compared with Example 10, the yield of the tomato 400 in Example 11 was improved. In Example 12, the shallot 500 was harvested 30 days before the peak fruiting period of the tomato 400, and the yield of the tomato 400 was 2355 kg / mu. The yield of tomato 400 is 2450 kg / mu. In Example 13, the mongolica 500 is harvested 38 days before the peak fruiting period of tomato 400, and the yield of tomato 400 is 2433 kg / mu. Compared with Example 13, the yield of tomato 400 in Example 12 is improved. In Example 14, the mongolica 500 is harvested 46 days before the peak fruiting period of tomato 400, and the yield of tomato 400 is 2399 kg / mu. Compared with Example 14, the yield of tomato 400 in Example 13 is improved.

[0105] In Example 10, the allium 500 was harvested 15 days before the peak fruiting period of the tomato 400. In Example 14, the allium 500 was harvested 46 days before the peak fruiting period of the tomato 400. In Example 11, the allium 500 was harvested 23 days before the peak fruiting period of the tomato 400. In Example 13, the allium 500 was harvested 38 days before the peak fruiting period of the tomato 400. Compared with Example 10 and Example 14, the adhesion strength of the fruit stalks of the tomato 400 in Examples 11 and 13 was stronger. In Example 12, the allium 500 was harvested 30 days before the peak fruiting period of the tomato 400. Compared with Example 11 and Example 13, the adhesion strength of the fruit stalks of the tomato 400 in Example 12 was stronger. In Example 12, the allium 500 was harvested 30 days before the peak fruiting period of the tomato 400. After harvesting, the flowering period of the allium 500 coincided with the peak fruiting period of the tomato 400. The adhesion strength of tomato 400 fruit stems in the above examples demonstrates that harvesting allium 500 before the peak fruiting period of tomatoes 400 affects the adhesion strength of the tomato 400 fruit stems, and that harvesting allium 500 30 days before the peak fruiting period of tomatoes 400 results in a stronger adhesion strength of the tomato 400 fruit stems. (Whether the flowering period of allium 500 overlaps with the peak fruiting period of tomatoes 400 was determined by harvesting allium 500 15, 23, 30, 38, and 46 days before the peak fruiting period of tomatoes 400 in Examples 5 to 9, and then manually observing the degree of overlap between the flowering period of allium 500 and the peak fruiting period of tomatoes 400.)

[0106] From the above examples (5 to 14), it can be seen that, regardless of whether brackish water or normal water is used for irrigation, harvesting allium 500 before the peak fruiting period of tomato 400 has a certain but not significant impact on the yield of tomato 400, and has a greater impact on the adhesion strength of the fruit stalks of tomato 400. However, the overall yield of irrigation with normal water is not as high as the yield of irrigation with brackish water, which also confirms the conclusions of Comparative Example 2 and Example 2 (compared with Example 2, Comparative Example 2 uses brackish water for irrigation, and the tomato yield is increased by 5.7%).
