The mechanized precision seeding technique of rapeseed refers to the optimal seeding amount, line spacing and hole spacing (or grain distance) according to the agronomic requirements after the harvest of the former sorghum crops, with the precision seeding technology as the core, integrated ditching, rotary tillage and mites The fertilization combined planter with multiple techniques such as fertilization and soil covering directly spreads rapeseed seeds to the ideal position of rapeseed in the ideal position of the field soil.
This technology can reduce rapeseed planting operations, shorten farming time, ensure farm time; reduce labor intensity, improve labor environment; significantly improve production efficiency, increase farmers' income, and promote the sustainable development of rapeseed industry. The technology can save labor, save seeds and save fertilizer, and increase the efficiency of more than 120 yuan per acre. At the same time, the straw can be returned to the field to increase soil organic matter content and fertility.
skills requirement:
1. Preparation of the plot: The surface of the plot should be relatively flat with a slope of no more than 15 degrees; the height of the stubble of the former crop should be no more than 300 mm; the relative humidity of the soil is 40%-60%.
2, seed preparation: the selection of high-quality seeds, the seed moisture content is not higher than 9%, the clarity is not less than 97%, the germination rate is more than 90%. Selective treatment before planting, in line with the requirements of mechanized operations.
3. Fertilizer preparation: Use granular fertilizer to prevent chemical fertilizer from agglomerating in the fertilizer tank.
4. Sowing date selection: determined according to local climatic conditions. The amount of mechanical precision seeding is generally controlled at 150-250 g/mu.

Vitamins are a type of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. In terms of physiological functions, vitamins are neither a raw material for tissues nor a substance for supplying energy, but they are an indispensable substance for the body. It has many types and different chemical structures. Most of them are the components of the coenzyme (or prosthetic group) of certain enzymes. They are the indispensable compounds for maintaining the normal growth (growth, health, reproduction and production function) of the body. It plays a catalytic role in the body to promote the synthesis and degradation of major nutrients (proteins, fats, carbohydrates, etc.), thereby controlling metabolism. Vitamins are essentially low-molecular organic compounds. They cannot be synthesized in the body, or the amount synthesized is difficult to meet the needs of the body, so they must be supplied from the outside. The daily requirement of vitamins is very small (usually measured in milligrams or micrograms). They are neither a raw material for body tissues nor a substance for energy supply in the body. However, they do not regulate material metabolism, promote growth and development, and maintain physiological functions.
