The slogan of wheat planting mechanization

As one of the main food crops in China, wheat has a huge planting area, and the planting area also runs through the north and south. In China's wheat planting industry, wheat can be divided into winter wheat and spring wheat according to the planting season. Among them, winter wheat is currently being planted, mainly in areas with relatively warm temperatures, while spring wheat is mainly used in the colder northeast and northwest regions.

Today, I will share with you some precautions for spring wheat planting! 1. Sowing time: The environment and climate in different areas are different, so the sowing time is not necessarily, but generally speaking, the sowing of spring wheat is concentrated in the middle and late March to the early April, and it can be sown when the surface thaws 3-5 cm after spring.

Second, grab the soil: Generally speaking, spring wheat is not short of water compared with winter wheat. After all, melting snow in winter can bring a lot of water. However, when the times were bad, it was necessary to grab the soil in time. Moreover, due to the rapid growth and development of spring wheat in the early stage, the demand for field fertilizers is relatively high, especially the sensitivity of spring wheat to phosphorus is higher than that of winter wheat, so it is necessary to increase fertilizers according to soil fertility and apply sufficient fertilizers when sowing.

Third, seed treatment: whether it is spring wheat, winter wheat or other crops, seed treatment is necessary. Seed dressing with chemicals after drying can effectively improve the germination rate of seeds and reduce the probability of pests and diseases.

Fourth, field management: when planting spring wheat, we should pay attention to planting density. If it is too dense, the field will be closed. If it is too thin, the output will be insufficient. Generally, 22~28 kilograms are sown per mu. Fertilization for spring wheat is to apply sufficient fertilizer, mainly nitrogen fertilizer and phosphorus fertilizer, and then topdressing and supplementing trace fertilizer according to the growth and plot conditions.

The main sowing methods of wheat are strip sowing, sowing and hole sowing. Drill sowing has uniform seed dropping, uniform soil covering depth, neat seedling emergence, ventilation and light transmission in the middle and late stage, which is convenient for mechanized management. Sowing is mostly used in wheat-cotton intercropping or rice-wheat rotation areas. When the soil is sticky and the soil preparation is difficult, it is beneficial to seize time and save labor. The individual distribution of seedlings and the nutritional area of each plant are good, but the depth of seeds buried in the soil is inconsistent. Hole sowing, also known as on-demand sowing or nest sowing, is used in the wheat field after rice. It has the advantages of centralized fertilization, uniform sowing depth, neat emergence and convenient field management, but it has many flowers, large hole spacing and few ears, which affects the yield.
