Over the years, the author has made a series of improvements to rapeseed cultivation methods, and has achieved good results with high production, stable production, and low production costs. First, nursery (1) Selection of good varieties: varieties with strong growth potential before the winter, strong resistance to disease, lodging resistance, strong cold resistance, good yield stability, and high yield potential, such as Yangyou No. 5, Yangyou No. 6, Dongyou No. 18, Huiyou 50, etc. . Shi Lifeng must be properly planted and it is not suitable for this cultivation method. (2) Rotary tillage after sowing: sowing on September 15-20. Each acres of field with seedbed 80 square meters, need 120 grams of seed, manure 200 kg, monoammonium phosphate 2 kg, potassium chloride 1.5 kg, less nitrogen fertilizer is conducive to vegetable seedlings robust, easy to live after planting. Spread the seed and fertilizer directly on the seedbed and use a rotary tiller to rotate the soil. If the soil moisture is high, it should be rotated shallowly. After rotary tilling, there is no need for leveling and repression, and no watering is required for droughts, ensuring uniform emergence and no clustered seedlings. No need for seedlings, generally 100-130 plants per square meter emerged. (3) Moderate chemical control: 15% paclobutrazol in the 3-leaf stage was 1200-fold liquefaction-controlled, which significantly reduced tall plantlets and bent-rooted plantlets. Second, transplanting (1) Don't transplant early: Practice has proved that rape that was transplanted early before October 20th has a short seedling age, thin leaves, plus high temperature, strong sunlight, and large evaporation, even if it is poured once or twice alive. Most of the leaves also died, leaving only the heart and leaves, and there were too many trees, and the grass was seriously damaged. Transplanting from late October to early November has a short seedling period, and can avoid convulsions before winter, prosperous growth without sensation before winter, significant reduction of yellow leaves, and mild incidence of sclerotia. There was no need for weeding in the fields. (2) Rotation of fertilizers into the soil: 10 kg of monoammonium phosphate, urea, and potassium chloride are used for each mu of field, and the soil is mixed and rotated to rot till the soil, and no fertilizer is applied before winter. (3) Appropriately sparsely planted: After digging a good ditch, transplant Chaoyanggou to transplant, and determine the density according to variety, seedling condition, fertility, and transplanting as soon as possible, generally 6000-8000 plants per mu, row spacing 40-50 cm, plant spacing 20-30 cm. . (4) Take Shimoda: Spray with avermectin (or pyrethrin) and carbendazim before transplanting to prevent and treat pests. No longer use medication before the spring. (5) Do not water the water: When raising the seedlings, use a pot to cut the seedlings deep into the soil, so as to prevent the roots from breaking the stems. The roots shall be covered with soil as much as possible, and the mushy river mud shall be used to remove the roots. Select transplanting in the afternoon or cloudy day, planting and then stepping on solid, do not pour water. Third, management (1) Reapplying manure: In the first half of March of the next year, when the pods are pumped to 3-4 centimeters, 15 kilograms of urea are spread in Chaoyanggou. In combination with weeding, flatten the Chaoyanggou manure root. (2) Controlling and strengthening: In mid-March, 30 centimeters high, with 15% paclobutrazol per acre, plus 40 grams of carbendazim spray, to prevent and cure pests, and to promote resistance. (3) Fertilizers mixed and sprayed: Each of the initial flowering stage and full flowering stage is mixed with one spray of fertilizer and fertilizer. Each use of 25% carbendazim 250 grams, 150 grams of borax, 150 grams of potassium dihydrogen phosphate, 20 milliliters of avermectin plus water 50 kg spray. Fourth, harvest When most of the pods in the fields are yellowed, the yellow angles of the flower stems of the main stem turn yellow, and when the granules turn green from brown to red, they will be harvested before the morning of 10 o'clock when the dew is not dry, and will spread in the sun. After drying, spread non-woven fabrics on the ground, threshing in situ, and return the fruit shells to the field. Disclaimer: Some articles in this website have been transferred from the Internet.
