What is the no-tillage planting technology of rape? Can you be more specific?

Rapeseed has an oil content of 40% to 50% and an oil yield of 35% to 38%. Pressed cakes contain 35% to 40% protein, various amino acids and minerals, such as phosphorus and potassium. Golden rape flowers can provide a good honey source for beekeeping. The first step is seed selection. There are many varieties on the market. Select varieties with high yield. Then choose a fertile land, sprinkle 3-4 kg of compound fertilizer (50 grams of rapeseed, for example, about 5 square meters) before turning over the soil, level the land, and you can sow. To achieve high yield, we must first master the sowing time. We usually sow between the autumnal equinox and the cold dew, which means that we sow earlier than wheat. Spread the fertilizer evenly into the ground, plow the ground, level and harrow it, and then gently harrow it after sowing the seeds.

Selection of seedbed: Choose plots with leeward and sunny, fertile soil and convenient management as seedbeds. In general, the area of seedbed and transplanting field is 1: 5-6, and the seedbed should be flat, thin and solid (the upper part is empty and the lower part is solid), and sufficient fertilizer should be applied. Rape planting methods are diverse, and land consolidation. According to the season, the survival rate of rape is very high, and late irrigation will effectively improve the yield. Become fertile and nutritious. 2. After fertilizing the cultivated land, you can sow. Generally, sowing at home is to dig shallow ditches in cultivated land and let rapeseed be buried in the soil. 3. After sowing in the ditch, cover it with soil. There is no need to cover them too thick. If they are too thick, they will be sown according to the sowing date. Planting rape is only the first step. Rape needs a comprehensive management process to have good yield and quality. Taking Brassica napus in western Sichuan as an example, this paper discusses how to grow rapeseed well. 50 cm to make a nest. Sow five or six seeds in each nest after the nest is finished, and then drench each nest with manure. After germination and emergence, the three leaves are United, leaving two strong seedlings in each nest. Field management after planting. Generally, 3000 ~ 5000 kg of high-quality fully decomposed farmyard manure, 20 ~ 25 kg of diammonium phosphate and 40 ~ 50 kg of potassium sulfate 10 ~ 15 kg or 45% ternary compound fertilizer are applied per mu.
