Rape must be formulated and fertilized

The national trial varieties Fengyou 701 and Zheshuang No. 3 are exclusively produced and operated by Zhongnong, and the high yield can reach more than 600 kg per mu. Formulated fertilization is required to achieve the desired yield.
1. Formulated fertilization seedbed per mus of high-quality decomposed farmyard manure 1500-2000 kg to increase soil organic matter and improve soil structure; high-quality compound fertilizer (N:P:K=15:15:15) about 20 kg; high-quality boron fertilizer 1 - 1.5 kg; 5 kg period can be sprayed with 0.2% of potassium dihydrogen phosphate solution 30 kg; 7-10 days before transplanting can be poured 0.5% of urea solution 90 kg for feeding fertilizer.
The transplanted Honda, the proportion of base seedling fertilizer and bud fertilizer was distributed and applied at 8:2. Before transplanting, the base fertilizer is about 1500 kg per mu, and the high-quality compound fertilizer is about 50 kg; the boron fertilizer is about 1-1.5 kg; for the cold-soaked field, about 1.5 kg of zinc fertilizer can be added. The seedling fertilizer should be applied early, and the strong seedlings should be wintered. The seedlings should be 3-5 kg ​​of urea and 3-5 kg ​​of potassium fertilizer. At the same time, 0.2% potassium dihydrogen phosphate solution can be sprayed. Note that nitrogen should not be applied in the Spring to prevent lodging and late flowering. The application of live field-based seedlings and buds was similar to transplanting.
2, the use of boron fertilizer Rape is a highly sensitive crop of boron, such as the lack of boron, will result in reduced production or even the consequences. According to the survey, in the winter rapeseed production area of ​​the Yangtze River Basin, most of the soil is deficient in boron. Zhongnong Seed Industry has carefully selected two high-quality and high-efficiency boron fertilizers – strong boron and polymerized boron. Its boron content is 15% and 13%, respectively.
“Strong boron†is used as the base fertilizer. It is mixed with other fertilizers per acre and then applied once. For 12-14 leaves, use “polymerized boron†1-2 bags and water for 15-30 kg per mu. The solution is sprayed. Note that the seedling stage is the most sensitive period for rapeseed to boron. For example, boron deficiency is congenitally insufficient, and even if it is applied later, it cannot be completely compensated.
"Polymerized boron" is used to spray boron. Spray once in the bud stage and the beginning flowering stage. In order to improve the seed setting rate and prevent diseases such as sclerotinia, potassium dihydrogen phosphate and carbendazim can be sprayed at the same time. The specific dosage is 2-4 bags of polymerized boron, 100 grams of potassium dihydrogen phosphate, 100 grams of carbendazim, and 75-100 kilograms of water. Note that the bud stage and the initial flowering stage are the periods in which the amount of boron in the rapeseed is the largest. If it is lacking, the flower will be degraded and the flower will be unreal, which will result in a reduction in production. Therefore, it is necessary to spray boron in time.
The above is for medium-fertility fields, and for those with lower fertility, the amount of fertilizer should be increased depending on the situation.
