High-yielding winter wheat sowing technique

In accordance with the requirements of winter wheat seedling monitoring and monitoring, combined with the actual production of winter wheat in Jingning County, the seven aspects of soil preparation, formula fertilization, soil treatment, excellent use of improved seed, seed coating, standardized planting, and scientific management were adopted to promote the application of various technologies. Strive to make winter wheat production to a new level.

1, deep plowing. Choose rivers, terraces, or gentle slopes with slopes below 15 degrees. After harvesting, crops such as legumes, wheat, corn, flax, and oysters will be planted in a timely manner, and the soil will be loosened and ploughed. To achieve deep soil loose, smooth ground, soil fine cotton, no soil block, no roots, the virtual reality, in order to increase soil water storage capacity, fully accept the natural rainfall, so that autumn rain.

2, formula fertilization. According to the farmland fertility investigation, soil nutrient tests and field formula fertilization test results, it is recommended that the fertility standards for high-yield winter wheat cultivation in the county include: 3000-4000 kg of high-quality farmyard manure, 15-20 kg of urea, and 40-50 kg of calcium sulphate. "Three fat pads blasted at the end."

3, soil treatment. For land plots with serious underground pests, combined with site preparation, use 40% phoxim 0.5 kg/mu, and mix the sand with toxic soil and spread it to the surface. Then, plow up the soil and level the surface.

4, choose a good seed. According to the distribution of winter wheat varieties in the county, the central and southern regions will plant Jingmai No. 1 and Zhongliang No. 24 with planting Zhongliang No. 25, Zhongliang No. 23 and Jingning No. 8; in the northwest, the planting of Jingning No. 9 and Jingning No. 10 will be promoted. No. 2, with planting Zhongliang No. 23, Zhongliang No. 24; Chuanshui District promotes planting of Jingning No. 10, Jingning No. 11 and Jingning No. 2.

5, seed coating. It strives to apply 40% phoxim and potassium dihydrogen phosphate to the seed coating of more than 80% of winter wheat in the county to effectively control underground pests and promote full seedling growth.

6, standard planting. The full promotion of the Sanli Plough Planter and the mechanical six-plow planter will allow precise sowing. The amount of grain per acre will be 14-15 kg. The amount of seeds under the film will be 13 kg and the total seed volume will be 12 kg.

7, scientific management. Immediately after the emergence of wheat seedlings fill seedlings, sparsely thickened seedlings, timely recovery fertilizer after returning green, early spring to strengthen the control of wheat spider mites, leafhoppers, after the jointing to strengthen powdery mildew, rust, wheat bran control.
