Field management method for high yield of rapeseed

Rapeseed is rich in nutrients and has a high vitamin C content. Rapeseed generally grows in a relatively humid climate, such as the south of our country. Rape has many uses, for example, rapeseed can be eaten when it is not contained.

Promote spring hair:

The growth of rapeseed in autumn and winter is all over the place. Promoting spring hair is the key to the transformation of rapeseed seedlings this year, and it is also an important measure to avoid the cold and late defermentation. In general, in the beginning of March, 6-8 kg of urea per mu or 12-15 kg of ammonium sulfate can be applied. Fields with heavy seasonal drought in the upper reaches of the Yangtze River in the upper reaches of the Yangtze River should be repaired by rain or combined with hydration. For late-seeded fields, the application of manure fertilizer should pay attention to the balance of NPK, avoiding partial application of nitrogen fertilizer and causing late lodging.



Anti-staining:



In the Yangtze River Basin, there is a lot of rain in spring. If the former is rice, the soil water content will be higher. The high humidity in the field is not only not conducive to the growth and development of rape roots, early premature aging and lodging, and exacerbate the onset and spread of diseases. On the basis of opening the "three ditch" before winter, we should arrange the ditch in time after the spring, and adhere to the "three ditch" to ensure that there is no water in the rain.



Prevention of pests and diseases:



During the winter season, the rapeseed production area has many cold, rainy and snowy weather, and the plants are frozen and can resist the pests and diseases. The upper reaches of the Yangtze River are affected by the seasonal drought in winter and spring. The aphid attack is heavier. It is necessary to use the new high-fat film spraying leaf surface for control during the convulsion and flowering period. It can be kept warm, moisturized, and infected by prion to improve the effect of pesticides. At the beginning of flowering period, the targeted medicine + vegetable strong stem spirit will be promoted to promote growth and robustness, and the vegetable seedlings will grow vigorously, and the stems will be coarse and strong, with high yield and high quality.
