[0025] The present invention will be further described below in conjunction with specific implementation cases and the accompanying drawings, but the present invention is not limited to these embodiments.

[0026] Embodiment 1

[0027] As Figure 1 shown, the present invention discloses a cultivation method for reducing the drying degree of soft-seed pomegranate branches, including:

[0028] Step S1: Winter wheat planting; specifically, winter wheat is planted according to the local planting time and requirements; the local planting time is from late September to early October. The planting requirements include: planting in the north-south direction, with a planting width of 4 m and an interval of 1 m.

[0029] Before winter wheat planting, it also includes: applying farmyard manure and reaching the optimal fertilization amount, deeply plowing and leveling the land to meet the requirements for winter wheat planting.

[0030] Step S2: Digging planting holes; specifically, planting holes are dug along the center line of the partition area according to the hole-digging requirements, and the topsoil and new soil are placed separately; the center line of the partition area is the center line between two adjacent ridges of winter wheat; the hole-digging requirements include: a plant spacing of 2 m and a digging depth of 80 cm × 80 cm × 60 cm.

[0031] Step S3: Seedling planting; specifically, before the soft-seed pomegranate seedlings germinate, the seedlings to be planted are selected, transported to the seedling planting area, and then pretreated, and the pretreated seedlings to be planted are planted; the pretreatment includes soaking for 24 hours and then treating with rooting powder; the soft-seed pomegranate is preferably the "Tunisian" soft-seed pomegranate; the seedlings to be planted are 1-2-year-old high-quality "Tunisian" soft-seed pomegranate seedlings.

[0032] The present invention plants the pretreated seedlings to be planted, specifically including: judging whether planting can be carried out within a set time; if planting can be carried out within the set time, then planting is carried out; if planting cannot be carried out within the set time, then temporary planting is carried out, and planting is carried out after the soil surface layer of 0-40 cm thaws, and planting is carried out in a prostrate manner with a 30-degree inclination to the south. The set time here is set according to actual needs and will not be specifically described here.

[0033] Step S4: Film covering and soil covering; specifically, after planting, the tree basin is covered with a film, and the root-fixing water is thoroughly irrigated. When the first set requirement is met, the seedlings to be cultivated are pressed down, and the middle part of the seedlings to be planted is first covered with new soil and then covered with topsoil, with a soil covering thickness of 5 cm. When the second set requirement is met, the soil covering is removed.

[0034] When the infiltration rate of the fixed root water of the present invention is less than the set value, it is considered that the irrigation is thorough; the first setting requirement includes: the average height of winter wheat is greater than the first set value or the dryness of the surface soil in the field is greater than the dryness threshold; the second setting requirement includes: the average height of winter wheat is greater than the second set value; wherein, the second set value is greater than the first set value. In this embodiment, the first set value is 15 cm, the second set value is 30 cm; the dryness threshold is set according to actual needs.

[0035] Step S5: Water and fertilizer management; specifically, after planting, irrigate the fixed root water at least 3 times, and irrigate in a timely manner according to the set time and the dry and wet conditions in the later stage; do not apply soil fertilizer before the planted seedlings germinate, and when the new branches reach more than 30 cm, apply hole-shaped fertilizer at a distance of 30 - 40 cm from the tree trunk.

[0036] Step S6: Tree body management; specifically, after the seedlings germinate, remove the buds within 30 cm from the base of the tree trunk and cut off the upward-growing branches.

[0037] During the creeping cultivation of southern Xinjiang soft-seed pomegranates, planting techniques, climatic conditions, field management, etc. affect the degree of branch drying. Therefore, in the present invention, soft-seed pomegranates are intercropped with winter wheat. The winter wheat forms a windbreak, reduces the wind speed between rows, increases the air humidity between rows, reduces the air temperature between rows, provides a better microhabitat for the soft-seed pomegranates to slow down seedlings when establishing orchards, reduces the degree of branch drying, improves the planting survival rate of soft-seed pomegranates, and is conducive to accelerating the rapid development of the southern Xinjiang soft-seed pomegranate industry.

[0038] The present invention adopts a planting mode of intercropping soft-seed pomegranates with winter wheat. Before planting winter wheat, apply sufficient base fertilizer to improve soil fertility. In the initial stage of planting pomegranate seedlings in spring, the plant height of winter wheat is relatively low. Cover the soil to reduce the transpiration of the tree trunk, and cover the film to increase the ground temperature and promote the germination of roots. In the later stage, the dynamic growth of winter wheat can provide a windbreak for soft-seed pomegranates, increase the air humidity, reduce the degree of branch drying of soft-seed pomegranates, and improve the planting survival rate of seedlings.

[0039] Specific examples

[0040] The implementation site is located in the 51st Regiment of Tumushuke City, and its local climate belongs to the warm temperate continental arid climate. Its characteristics are hot summers, cold winters with large temperature differences, little rain, strong winds and dry air. The local annual sunshine hours are 4,430 hours, the average annual evaporation is 2,178.5 mm, the annual rainfall is 40 mm, and the dominant wind direction is the northeast wind, followed by the southwest wind. The temperature at the experimental site in 2020 is as Figure 2 shown in Table 1; among them, Figure 2 in, the circle represents the average low temperature, the triangle represents the extreme high temperature, the quadrilateral is the extreme low temperature, and the pentagon represents the average high temperature.

[0041] ;

[0042] Implementation site investigation method: The investigation was carried out by random sampling method for on-site measurement, and the physical parameters that mainly affect the condition of branch drying in the field were quantitatively analyzed.

[0043] Five representative fixed measuring points were randomly selected for the experiment, and instruments were arranged for fixed-point measurement of air temperature and humidity, wind speed, and soil surface temperature and humidity at different heights.

[0044] For the positioning of the measuring instruments, according to the growth height of winter wheat at different times, the upper, middle, and lower canopies of the wheat were distinguished. Using temperature and humidity recorders and wind speed and direction recorders, the air temperature and humidity of different canopies of winter wheat in the experimental field, as well as the wind direction and wind speed conditions, were continuously recorded. Each measurement was taken three times in the morning, noon, and evening at intervals of 5 days, and the experimental records were well kept.

[0045] The experiment used the drying of some branches or the death of the whole plant as the sign of shoot blight. Fifteen plants were randomly selected and tagged for fixed-plant measurement. Three branches were randomly selected from the upper and middle parts (the bottom is the main trunk without branches) of the plants to observe the branch color, measure the drying length of the branches, and calculate the average drying length at different spatial heights.

[0046] Example 2

[0047] Interplanting winter wheat with "Tunisia" soft-seed pomegranate

[0048] (1) Site selection and orchard establishment: In the autumn of 2020, in the 19th company of the 51st regiment in Tumushuke City, sandy loam land with medium fertility was selected for orchard establishment; before planting winter wheat in autumn, the land was prepared, and 3 - 4 tons of well-rotted farmyard manure was applied and deeply plowed to ripen the soil.

[0049] (2) Varieties: According to the local climate conditions, 185 mu of 1-year-old "Tunisia" soft-seed pomegranate was introduced and planted, and the early-maturing variety "Xindong 22" was selected for winter wheat.

[0050] (3) Seedling treatment: Before the "Tunisia" soft-seed pomegranate seedlings from Liugou, Xingyang, Henan did not germinate on March 18, 2021, 1-year-old high-quality "Tunisia" soft-seed pomegranate seedlings were transported. After arrival, they were soaked for 24 hours in time, treated with rooting powder, and temporarily planted.

[0051] (4) Sowing: The sowing date of winter wheat was in the late September of 2020, with a sowing width of 4 m and an interval of 1 m, and the space for future pomegranate planting was left between the rows.

[0052] (5) Planting: The row spacing of "Tunisia" soft-seed pomegranate was 2.0 m × 5.0 m, and holes with a depth of 80 cm × 80 cm × 60 cm were dug, with the topsoil and subsoil separated and placed on each side; on March 27, 2021, the pomegranate seedlings were planted. They were taken from the temporary planting area and planted immediately to reduce the transpiration water loss of the seedlings, and were planted in a 30-degree southward inclined prostrate manner.

[0053] (6) Film mulching and soil covering: After planting pomegranates, the tree basins are covered with film, and the root-fixing water is thoroughly irrigated (i.e., when the infiltration rate of the root-fixing water is less than the set value). At this time, the height of winter wheat seedlings is about 15 cm. Since the ability to provide windbreaks for pomegranate seedlings is low, when the surface soil in the field is semi-dry, 5 cm of soil is covered on the middle part of the seedlings, and the saplings are pressed down to reduce wind pumping and transpiration water loss from the tree trunk. When the seedling height reaches more than 30 cm on April 15th, the covered soil is removed, and the dynamic growth of wheat in the later stage continuously provides windbreaks for pomegranate seedlings.

[0054] (7) Fruit tree water and fertilizer management: After thoroughly irrigating the root-fixing water, following the principle of applying small amounts multiple times, water is irrigated every 15 days thereafter, and watering is controlled by the end of August; no fertilizer is applied before the pomegranate seedlings germinate, and after germination, when the new branches reach about 30 cm, 30 - 50 g of nitrogen and phosphorus fertilizer is applied per plant.

[0055] (8) Field management: In the middle and late February, when winter wheat returns to green, harrowing and loosening the soil are carried out to increase the soil temperature. After the seedlings germinate, the buds within 30 cm at the base of the tree trunk are promptly removed, the upward-growing branches are pruned, and weeds are removed regularly.

[0056] In June 2021, at this time, the height of winter wheat is about 78 cm, and the inclined height of pomegranate seedlings is about 35 cm; the dried lengths of the branches of 15 randomly selected seedlings are measured, and the average dried lengths at different spatial heights are calculated. The survey results are shown in Table 2:

[0059] Planting Muskmelons Intercropped with 'Tunisia' Soft-seed Pomegranates

[0060] In view of the characteristics of small crowns, low land and light energy utilization rates in the initial stage of planting young soft-seed pomegranate trees, muskmelon intercropping cultivation measures are taken to improve the benefits of the newly established orchard.

[0061] (1) Site selection and orchard establishment: In the spring of 2021, in the 12th company of the 51st regiment in Tumushuke City, sandy loam soil with medium fertility is selected for orchard establishment, and 3 - 4 tons of well-rotted farmyard manure is applied, and the soil is deeply plowed to ripen the soil.

[0062] (2) Varieties: According to the local climate conditions, 1-year-old 'Tunisia' soft-seed pomegranates are selected for introduction and planting for fruit trees, and 'Tangwang Ancient Melon' is selected for muskmelons.

[0063] (3) Seedling treatment: Before the pomegranate seedlings from Liugou in Xingyang, Henan did not germinate on March 18, 2021, 1-year-old high-quality 'Tunisia' soft-seed pomegranate seedlings were retrieved, soaked for 24 hours in time after arrival, treated with rooting powder, and temporarily planted.

[0064] (4)Sowing: The sowing date of melons was March 18, 2021. The cultivation method of small arched double-film and furrow irrigation (depth 50 cm, width 80 cm) was adopted, and the planting density was 0.5 m × 1.0 m in row spacing.

[0065] (5)Planting: The row spacing of "Tunisia" soft-seed pomegranates was 2.0 m × 5.0 m. Holes with a depth of 80 cm × 80 cm × 60 cm were dug, and the topsoil and subsoil were separated and placed on each side. On March 27, pomegranate seedlings were planted. They were taken from the temporary planting area and planted immediately to reduce transpiration water loss of the seedlings. They were planted in a prostrate manner with a 30-degree inclination to the south.

[0066] (6)Mulching with soil: After the pomegranates were planted, the tree basins were covered with plastic film and thoroughly irrigated with root-fixing water. At this time, the melons had just emerged and could not provide a windbreak for the pomegranate seedlings. Therefore, when the surface soil in the field was semi-dry, 5 cm thick soil was covered in the middle of the seedlings and the saplings were pressed down to reduce wind damage and transpiration water loss of the tree trunks. The soil covering was removed when the melon seedlings reached the vine-extending stage on April 15.

[0067] (7)Fertilizer and water management for fruit trees: After thoroughly irrigating the root-fixing water, following the principle of applying small amounts but multiple times, irrigation was carried out every 15 days thereafter, and watering was controlled by the end of August. No fertilizer was applied before the pomegranate seedlings germinated. After germination, when the new branches reached about 30 cm, 30 - 50 g of nitrogen and phosphorus fertilizers were applied to each plant.

[0068] (8)Field management: Before planting the pomegranate seedlings, harrowing and loosening the soil were carried out to increase the soil temperature. After the planted seedlings germinated, the buds within 30 cm from the base of the tree trunk were promptly removed, the upward-growing branches were pruned, and weeds were removed regularly.

[0069] This investigation was carried out in June 2021. At this time, the melon seedlings in Plot 12 were about 20 cm tall, and the inclined height of the pomegranate seedlings was about 35 cm. The dry length of the branches of 15 randomly selected seedlings was measured, and the average dry length at different spatial heights was calculated. The investigation results are shown in Table 3:

[0071] Example 4

[0072] Intercropping of "Tunisia" soft-seed pomegranates and cotton

[0073] (1)Site selection and orchard establishment: In Plot 12, Regiment 51, Tumushuke City, sandy loam land with medium fertility was selected to establish an orchard, and 3 - 4 tons of well-rotted farmyard manure was applied, and deep plowing was carried out to ripen the soil.

[0074] (2)Varieties: According to the local climate conditions, 1-year-old "Tunisia" soft-seed pomegranates were introduced and planted for fruit trees, and Zhongmian 87 was selected for cotton.

[0075] (3)Seedling treatment: Before the pomegranate seedlings in Liugou, Xingyang, Henan germinated on March 18, 2021, one-year-old high-quality "Tunisia Soft-seed Pomegranate" seedlings were retrieved, soaked for 24 hours in time after being transported, treated with rooting powder, and temporarily planted.

[0076] (4)Planting: The row spacing of "Tunisia" soft-seed pomegranate is 2.0 m × 5.0 m. Dig holes with a depth of 80 cm × 80 cm × 60 cm, separate the topsoil and subsoil, and place them on each side; On March 27, plant the pomegranate seedlings. Take them from the temporary planting site as they are planted to reduce transpiration water loss of the seedlings. Plant them prostrate at an angle of 30 degrees southward, and leave a 4m spacing between each row of seedlings for sowing cotton seeds.

[0077] (5)Sowing: The sowing date of cotton is April 10, 2021. Adopt the cultivation method of equal-row strip sowing and covering with plastic film. The sowing width is 4 m, with an interval of 1 m, and the space between rows is for planting pomegranates.

[0078] (6)Covering with film and covering soil: After the pomegranates are planted, cover the tree trays with plastic film and irrigate thoroughly with root-fixing water. At this time, there are no windbreaks in the field; Therefore, when the surface soil in the field is semi-dry, cover the middle part of the seedlings with 5 cm thick soil, and press down the saplings to reduce wind pumping and reduce transpiration water loss of the tree trunks; When the cotton seedlings reach about 15 cm in height on May 25, remove the covered soil. The dynamic growth of cotton in the later stage can continuously provide windbreaks for the pomegranate seedlings.

[0079] (7)Water and fertilizer management: After thoroughly irrigating the root-fixing water, follow the principle of applying small amounts but multiple times, and irrigate once every 15 days thereafter. Control watering by the end of August; Do not apply fertilizer before the pomegranate seedlings germinate. After germination, when the new branches reach about 30 cm, apply 30 - 50 g of nitrogen and phosphorus fertilizer per plant.

[0080] (8)Field management: Before planting the pomegranate seedlings, harrow the soil to loosen it and increase the soil temperature. After the planted seedlings germinate, promptly remove the buds within 30 cm from the base of the tree trunk, cut off the upward-growing branches, and remove weeds regularly.

[0081] This investigation was conducted in June 2021. At this time, the cotton seedlings in Plot 12 were about 20 cm tall, and the inclined height of the pomegranate seedlings was about 35 cm; Measure the dry length of the branches of 15 randomly selected seedlings, and calculate the average dry length at different spatial heights. The survey results are shown in Table 4:

[0082] ;

[0083] From the experimental results in Table 2 - Table 4, it can be concluded that: Among the three different intercropping examples monitored in June 2021, the intercropping of "Tunisia" soft-seed pomegranate and winter wheat has an obvious preventive effect on inhibiting the drying of branches, and the survival rate of fruit trees increases by about 30%.

[0084] Such as Figure 3As shown in the figure, where (a) is the general layout plan of the compound planting, (b) is the schematic diagram of the planting effect in the field, and (c) is the schematic diagram of the sequential change of plant growth in different months. As Figures 3 - 4 shown, long-term field observations found that when the seedlings of soft-seeded pomegranate were planted at the end of March, the average height of winter wheat was about 15 cm. In April, after winter wheat entered the jointing stage, the plant height increased rapidly, forming a windbreak, increasing air humidity, reducing trunk transpiration, and providing a good microhabitat for the survival of soft-seeded pomegranate; after melons were sown in the middle and late March, the plant height of melons was within 10 cm at the beginning of May; it was less than 20 cm in June, and the effect of providing a good environment for pomegranates was weak; cotton was sown from late March to early April and squatted seedlings before the end of May, and the seedling height was controlled within 20 cm; therefore, intercropping melons or cotton could not form direct and effective protection for soft-seeded pomegranate seedlings with a plant height of 60 cm during the slow seedling survival period from April to June.
