Description

Technical Field

[0001] The invention relates to the technical field of rapeseed planting, in particular to a mechanized production method of wide-narrow hybrid rapeseed seeds. Background Art

[0002] With the development of social economy, the agricultural field is facing many challenges and changes. Among them, in the rapeseed planting industry, the change of labor structure has brought some impacts on production. For example: in rapeseed planting, traditional planting and management methods rely on a lot of manual operations. From sowing, field management to harvesting, all links require sufficient manpower, which not only increases the economic burden of growers, but also seriously affects production efficiency and economic benefits. At the same time, many growers blindly compress the spacing between male parent rows in order to expand the planting area of ​​female parents, and even have two rows of male parents overlapped into one row, making the male parent plants thin and small, and the number of branches is reduced, which leads to a significant shortening of the flowering period, serious shortage of pollen and uneven quality. In the pollination stage, the female parent cannot obtain enough high-quality pollen, the fruiting rate drops sharply, and the production output is reduced. In addition, in the male parent removal link, long-term reliance on manual operation not only has high labor costs, but also the cut male parent plants have the ability to ripen, which is easy to mix into the female parent when harvesting, which has a serious negative impact on the quality of the female parent F1 seeds, further reducing the quality of rapeseed seeds, thereby reducing the comprehensive benefits of wide and narrow hybrid rapeseed seed production.

[0003] In view of this, a mechanized production method for wide and narrow width hybrid rapeseed seeds is urgently needed. Summary of the invention

[0004] The object of the present invention is to provide an efficient mechanized production method for wide and narrow width hybrid rapeseed seeds to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides a mechanized production method of wide and narrow width hybrid rapeseed seeds, comprising the following steps:

[0006] S1. Preliminary preparation: determine the width ratio between the maternal parent and the paternal parent;

[0007] S2, sowing stage: using rapeseed sowing machinery, sowing the female and male rapeseeds respectively according to the pre-planned row spacing and number of rows;

[0008] S3. Field management: Rapeseed field management, including fertilizer management, water management, pest and disease control, and weed control;

[0009] S4. Pollination management: During the rapeseed flowering period, pay attention to the flowering of the male and female plants and carry out pollination work;

[0010] S5. Mechanical removal of male plants: After the male plants have completed the pollination task, use a mechanized lawn mower to cut off the male plants from the roots, crush them, and then evenly spread them in the field as organic fertilizer;

[0011] S6. Harvesting of mother plants: When the mother plant rapeseed matures, use mechanized harvesting and separation equipment to carry out harvesting operations.

[0012] As a further improvement of the technical solution, in S1, the width ratio of the maternal parent to the paternal parent is 3:1 or 2:1, wherein:

[0013] When the width ratio of the female parent to the male parent is 3:1, the female parent is planted in 18 rows and the male parent in 6 rows;

[0014] When the width ratio of the female parent to the male parent is 2:1, the female parent is planted in 16 rows and the male parent is planted in 8 rows.

[0015] As a further improvement of the technical solution, in S1, the row ratio of the female parent is positively correlated with the amount of pollen in the male parent of a single strain.

[0016] As a further improvement of the technical solution, in S1, a 1.4m black film is used for the parent row, and each film surface is about 1.2m after covering with soil.

[0017] As a further improvement of the present technical solution, in S2, the sowing depth of the female parent is 2cm-3cm, and the sowing depth of the male parent is 3cm-4cm.

[0018] As a further improvement of the present technical solution, in S6, the mechanized harvesting and separating equipment adopts a segmented mechanized harvesting and separating equipment.

[0019] As a further improvement of the present technical solution, in S6, the mother rapeseed harvesting operation first uses a cutting table to cut down the mother rapeseed plants and neatly spread them in the field; then, the cut rapeseed plants are transported to a threshing device through a conveying device for threshing and separation, and then the seeds are separated from the straw and impurities; finally, the harvested seeds are cleaned, dried and stored.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the mechanized production method of wide-narrow hybrid rapeseed seeds, by reasonably planning the width ratio and number of rows between the female parent and the male parent, the method is flexibly adjusted according to the pollen amount of the male parent, so as to fully utilize land resources and ensure the pollination effect, greatly improve the yield of hybrid seeds, and effectively improve the seed quality and fruit set rate through the operation of sowing, field and pollination management. The male parent is mechanized to be cleared and returned to the field, reducing labor costs and labor intensity, while turning waste into treasure to increase soil fertility, avoiding the adverse effects of the male parent residual plants on the female parent harvest, and the female parent is mechanized to be harvested and separated in sections and subsequently processed, so as to achieve efficient and high-quality harvesting, thereby improving the comprehensive benefits of wide-narrow hybrid rapeseed seed production. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 The present invention is a flowchart of the mechanized production method of wide and narrow width hybrid rapeseed seeds. DETAILED DESCRIPTION

[0023] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0024] according to Figure 1 As shown, the embodiment of the present invention provides a mechanized production method of wide and narrow width hybrid rapeseed seeds, comprising the following steps:

[0025] Step 1: Preliminary preparation: Determine the width ratio of the female parent to the male parent, plan the planting area, and improve land utilization. The width ratio of the female parent to the male parent is 3:1 or 2:1, where:

[0026] When the width ratio of the female parent to the male parent is 3:1, the female parent is planted in 18 rows and the male parent in 6 rows;

[0027] When the width ratio of the female parent to the male parent is 2:1, the female parent is planted in 16 rows and the male parent in 8 rows;

[0028] The mother row uses 1.4m black film, and each film surface is about 1.2m after covering with soil;

[0029] The row ratio of the female parent is positively correlated with the amount of pollen in the male parent of a single line. When the male parent of a single line can produce more pollen, the ratio of the number of rows of the female parent relative to the male parent can be appropriately increased in the planting plan. For example, if the male parent has sufficient pollen, you can plant more rows of the female parent to allow the female parent to make full use of the male parent's pollen for pollination, thereby increasing the yield of hybrid seeds; on the contrary, if the male parent has a relatively small amount of pollen, then the row ratio of the female parent relative to the male parent should be appropriately reduced. Because the amount of pollen is limited, reducing the number of rows of the female parent can ensure that each female parent can obtain enough pollen to complete pollination, thereby ensuring the fruit set rate and avoiding poor fruit set of the female parent due to insufficient pollen, which affects the final yield and quality of hybrid rapeseed seeds.

[0030] Step 2, sowing stage: Use rapeseed sowing machinery to sow the female and male rapeseed plants separately according to the planned row spacing and number of rows. The sowing depth of the female plant is 2cm-3cm, and the sowing depth of the male plant is 3cm-4cm, so that the seeds can be exposed to moisture and nutrients in the soil, which is conducive to uniform germination;

[0031] Step 3: Field management: Rapeseed field management, including fertilizer management, water management, pest and disease control, and weed control;

[0032] Step 4: Pollination management: During the rapeseed flowering period, pay attention to the flowering of the male and female plants for pollination. If natural pollination conditions are insufficient, use bee pollination or artificial assisted pollination to improve the pollination success rate, ensure that the female plant can be fully fertilized, increase the fruit setting rate and seed fullness, and ensure that the male plant can shed pollen normally to provide sufficient pollen for the female plant.

[0033] Step 5: Mechanical removal of male parents: After the male parent completes the pollination task, use a mechanized lawn mower to cut off the male parent plant from the root, crush it, and then evenly spread it in the field as organic fertilizer to increase soil fertility. At the same time, it reduces the impact of male parent residues on the harvest of female parents, reduces the cost and labor intensity of manual removal, and realizes the complete mechanized removal and return of male parents to the field;

[0034] Step 6. Harvesting of mother rapeseed: When the mother rapeseed is mature, mechanized harvesting and separation equipment is used for harvesting. The mechanized harvesting and separation equipment adopts segmented mechanized harvesting and separation equipment. For harvesting of mother rapeseed, first use a cutting table to cut down the mother rapeseed plants and lay them neatly in the field. Then, the cut rapeseed plants are transported to the threshing device through a conveying device for threshing and separation, and then the seeds are separated from the straw and impurities. Finally, the harvested seeds are cleaned, dried and stored to achieve efficient and high-quality harvesting operations.

[0035] In the invention, firstly, the width ratio of the female parent and the male parent and the number of planting rows are clearly determined, which can improve the land utilization rate. At the same time, it can match the pollen supply of the male parent with the pollination demand of the female parent, increase the yield of hybrid seeds, and use rapeseed sowing machinery to operate according to the plan during the sowing stage, such as scientifically implementing various measures in field management, pollination period management and other links, which can also effectively improve the quality and fruit set rate of rapeseed seeds; in addition, the mechanical removal of the male parent to achieve the return to the field and the mechanized harvesting of the female parent can reduce the production cost and labor intensity, and finally achieve the good effect of saving cost and increasing efficiency, and improve the mechanization and efficiency of wide and narrow hybrid rapeseed seed production.

[0036] In this mechanized production method of wide-narrow hybrid rapeseed seeds, by rationally planning the ratio of the width of the female and male parents and the number of rows, and flexibly adjusting according to the amount of pollen in the male parent, it can fully utilize land resources and ensure the pollination effect, greatly improve the yield of hybrid seeds, and effectively improve the seed quality and fruit set rate through the operation of sowing, field and pollination management. The mechanized removal and return of the male parent to the field reduces labor costs and labor intensity, while turning waste into treasure to increase soil fertility and avoid the adverse effects of the male parent's residual plants on the harvest of the female parent. The segmented mechanized harvesting and subsequent processing of the female parent achieves efficient and high-quality harvesting, thereby improving the comprehensive benefits of wide-narrow hybrid rapeseed seed production.

[0037] According to different raw material dosages, the mechanized production method of wide and narrow width hybrid rapeseed seeds provided by the present invention is further described through the following specific examples.

[0038] Example 1

[0039] Preliminary preparation: Determine the width ratio of female parent to male parent to be 3:1, plant 18 rows of female parent, use 1.4m black film, and each film surface is about 1.2m after covering with soil; plant 6 rows of male parent; After testing, the selected male parent strain has sufficient pollen, and this planting plan can make full use of the male parent pollen and increase the yield of hybrid seeds;

[0040] Sowing stage: Use rapeseed sowing machinery, according to the planned row spacing and number of rows, sowing depth of 2.5cm for female parent and 3.5cm for male parent, to ensure uniform seed emergence;

[0041] Field management: Fertilization management: 2200kg / mu of organic fertilizer and 35kg / mu of compound fertilizer as base fertilizer; 6kg / mu of urea at the seedling stage, 12kg / mu of urea and 6kg / mu of potassium chloride at the bud stage, and 0.25kg / mu of boron fertilizer at the flowering stage to ensure the nutrient needs of the plants at all stages; Water management: According to the weather and soil moisture conditions, timely irrigation should be carried out in case of drought to maintain the soil moisture content at 65%-75%, and attention should be paid to drainage and waterlogging prevention in the rainy season; Pest and disease control: Hang yellow boards to trap pests, conduct regular inspections, and spray 1500 times of avermectin solution for leaf miners; For powdery mildew, spray 800 times of triadimefon twice at the early stage of the disease; Weed control: Use S-isopropylamine to seal the soil for weeding before sowing, and weed manually 3 times during the growth period to ensure that there are no weeds in the field;

[0042] Pollination management: Natural pollination conditions are better during the flowering period. At the same time, 3 boxes of bees are placed in the field to assist in pollination, increase the success rate of pollination, and ensure that the female parent is fully fertilized;

[0043] Mechanical removal of male plants: After the male plants have completed pollination, use a mechanized mower to cut off and crush the male plants from the roots, evenly spread them in the field, and return them to the field to reduce labor costs and labor intensity;

[0044] Harvesting of mother rapeseed: When the mother rapeseed is mature, it is harvested with a segmented mechanized harvesting and separation equipment. The cutting table cuts down the plants and lays them neatly in the field. The plants are transported to the threshing device for threshing and separation. The seeds are then cleaned, dried and stored to achieve efficient and high-quality harvesting.

[0045] Example 2

[0046] Preliminary preparation: The width ratio of the female parent to the male parent is 2:1. The female parent is planted in 16 rows and the male parent in 8 rows. The female parent is covered with a 1.4m black film. After covering with soil, each film surface is about 1.2m. The pollen amount of the selected male parent is relatively small. The relative number of rows of the female parent is appropriately reduced to ensure the pollination effect.

[0047] Sowing stage: rapeseed sowing machinery sows according to the plan, with the sowing depth of the female parent at 2.2cm and the sowing depth of the male parent at 3.2cm to ensure good seed germination;

[0048] Field management: Fertilization management: 2000kg / mu of organic fertilizer for base fertilizer, 30kg / mu of compound fertilizer, 5kg / mu of urea in the seedling stage, 10kg / mu of urea and 5kg / mu of potassium chloride in the bud stage, and 0.2kg / mu of boron fertilizer in the flowering stage; Water management: Keep the soil moisture content at 60%-70%, irrigate in drought, and drain in rainy season; Pest control: Install insect-proof nets to prevent pests, and use 1000 times diluted Bacillus thuringiensis for prevention and control when diamondback moth is found; Use 700 times diluted triadimefon for rust, spray 3 times at the early stage of the disease; Weed control: Closed weeding before sowing, manual weeding twice during the growth period, and mechanical weeding once;

[0049] Pollination management: Due to strong winds during the flowering period, artificial pollinators are used to assist pollination and increase the fruit setting rate;

[0050] Mechanical removal of male parents: After pollination, the male parents are removed by a mechanized mower and returned to the field, and the operation is the same as in Example 1;

[0051] Harvesting of mother plants: Use segmented mechanized harvesting and separation equipment to harvest mother plants according to the process of felling, conveying, threshing, cleaning, drying and storage to ensure seed quality.

[0052] In order to verify that the mechanized production method of rapeseed seeds prepared in the embodiment of the present invention has good efficiency and quality, the mechanized production method of rapeseed seeds provided in the embodiment of the present invention is described through the following test examples.

[0054] The purpose of this test group is to explore the effects of different width ratios on the mechanized production method of rapeseed seeds, and to detect the efficiency, quality and fruit set rate of the mechanized production method of rapeseed seeds of the present invention.

[0055] Test objectives: Test group A and test group B respectively adopt the rapeseed seed mechanized production method provided in Example 1-2; control group A, control group B and control group C are used as the control examples, wherein:

[0056] Control group A

[0057] Planting plan: The traditional 2:6 planting pattern is adopted. The planting diagram is as follows:

[0058] ♀♀♀♀♀♂♂♀♀♀♀♀♂♂♀♀♀♀♀♂♂♀♀♀♀♀♂♂♀♀♀♀♀♂♂;

[0059] ♀Land utilization rate is 75%, ♂Land waste rate is 25%;

[0060] Sowing and field management: Manual sowing, sowing depth, fertilizer, water, pests and weed management are all based on experience, without precise standards;

[0061] Pollination management: natural pollination, no auxiliary pollination measures;

[0062] Male parent treatment: Manual removal of male parent, male parent residues are easily mixed into the female parent harvesting process;

[0063] Mother plant harvesting: manual harvesting, threshing and separation, low efficiency and difficult to ensure seed quality.

[0066] ♀♀♀♀♀♀♀♂♂♀♀♀♀♀♀♀♂♂♀♀♀♀♀♀♀♀♂♂;

[0067] ♀The land utilization rate is 80%, ♂the land waste rate is 20%, and there is also the problem of unreasonable row spacing of the male parent;

[0068] Other links: sowing, field management, pollination, male and female parent treatments are similar to those in Comparative Example 1, and no scientific and standardized mechanized production method is adopted.

[0069] Control group C

[0070] Planting plan: adopt 2:10 planting mode, the planting map is as follows:

[0071] ♀♀♀♀♀♀♀♀♂♂♀♀♀♀♀♀♀♀♀♂♂♀♀♀♀♀♀♀♀♀♀♂♂;

[0072] ♀Land utilization rate is 83%, ♂Land waste rate is 17%, and the poor growth of the male parent affects pollination;

[0073] Other operations: All production links use traditional methods, which are far from modern mechanized production methods, resulting in low rapeseed seed yield, poor quality and high production costs.

[0074] Test method: According to the high efficiency, high quality and fruit setting rate of the mechanized production method of rapeseed seeds of the present invention, tests were conducted respectively. The specific test methods are as follows:

[0075] High efficiency test method:

[0076] The time spent on the entire process from sowing to harvesting in each experimental group (experimental group A and experimental group B) and the control group (control group A, control group B and control group C) was recorded, including sowing time, field management operation time (fertilization, watering, weeding, pest and disease control and other operations were timed separately and accumulated), pollination time (natural pollination time and the additional time spent on auxiliary pollination measures), male parent removal time, and female parent harvesting time (cutting, transportation, threshing, cleaning, drying and other links were timed separately and accumulated).

[0077] Quality test method:

[0078] After the rapeseed seeds are harvested, a sufficient number of representative seed samples are collected from each experimental group and the control group, and a number of seed quality indicators are tested using professional seed testing instruments and standard testing procedures. The test items include seed purity, which is to determine the proportion of target rapeseed variety seeds in the sample; purity, which measures the content of impurities in the seeds; thousand-grain weight, which is calculated by precise weighing; germination rate, which is the ratio of the number of germinated seeds to the total number of seeds after a certain period of cultivation under suitable temperature, humidity and light conditions.

[0079] Fruit setting rate test method:

[0080] After the rapeseed entered the flowering and fruiting stages, the rapeseed plants of each experimental group and the control group were marked and observed; during the flowering stage, the number of flowers of the mother plant was recorded, and a certain number of representative mother plants were selected to count their total number of flowers; during the fruiting stage, the marked plants were observed again, the number of fruits was recorded, and the fruiting rate was calculated (fruiting rate = number of fruits ÷ number of flowers × 100%).

[0081] See Table 1 for specific test indicators.

[0082] Table 1 Test indicators of each sample

[0083]

[0084] According to Table 1, the above comparison data are summarized as follows:

[0085] In terms of high efficiency: the total time consumption of the experimental group A was 100 hours, the total time consumption of the experimental group B was 110 hours, and the control groups A, B, and C consumed 150 hours, 140 hours, and 160 hours, respectively; the present invention greatly shortens the entire production cycle from sowing to harvesting through reasonable planning of planting, mechanized operation, etc., thereby improving production efficiency and saving time costs.

[0086] Quality aspects:

[0087] Seed purity: test group A reached 98%, test group B was 97%, both significantly higher than the control group, the highest control group was only 92% (control group B), the lowest was control group C (88%); this shows that the present invention effectively ensures seed purity and improves the quality of rapeseed seeds through measures such as planting planning, scientific field management and avoiding mixing of male parent stumps.

[0088] Seed purity: the test groups A and B were 95% and 94% respectively, while the control group purity was generally lower, with the control group C being only 82%; the mechanized operation in the sowing and harvesting links and the weed control measures in the field management of the present invention reduced the possibility of impurities mixing into the seeds, thereby improving the seed purity.

[0089] Thousand-grain weight: the thousand-grain weight of test group A was 5.5g, and that of test group B was 5.3g. Among the control groups, control group B had the largest thousand-grain weight of 5.0g, and control group C had only 4.5g. The present invention enables the mother plant to grow robustly, the seeds to develop well, the thousand-grain weight to increase, the fullness and quality of the seeds to increase the yield potential compared with the traditional planting method through reasonable fertilization management, pollination management and scientific configuration of the male and female parents.

[0090] Germination rate: the germination rate of test group A was 90%, that of test group B was 88%, that of control group B with the highest germination rate among the control groups was 82%, and that of control group C was only 75%; the comprehensive management measures of the present invention ensure the vitality and health of the seeds, so that they have a higher germination rate under suitable conditions, and provide a better basis for the planting and emergence of rapeseed, while the germination rate of seeds under traditional planting methods is low, which affects the planting emergence and yield.

[0091] In terms of fruit setting rate: the fruit setting rate of test group A reached 90%, the test group B was 88%, the control group A was only 65%, the control group B was 70%, and the control group C was 60%; the present invention ensures that the female parent can be fully fertilized through reasonable planning of the width ratio of the male parent and the female parent and effective management of the pollination period (such as auxiliary pollination measures), thereby greatly improving the fruit setting rate. However, the traditional planting method has a low fruit setting rate due to the problems of insufficient pollen in the male parent and poor pollination conditions, which seriously affects the yield of rapeseed seeds.

[0092] It can be seen that the mechanized production method of wide-narrow hybrid rapeseed seeds of the present invention is effective. By scientifically planning the width and number of rows of the female and male parents, mechanized sowing, field management, pollination and harvesting, it effectively improves land utilization, seed quality and fruit set rate, shortens the production cycle, reduces costs, and thus improves the comprehensive benefits of wide-narrow hybrid rapeseed seed production.

[0093] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
