First, sowing
The time is from late April to early May. Drilling. First, the sorghum soil is smashed and finely smashed at a distance of 5cm to 5cm from the edge of the sagger. The spacing is 25-30cm, and the depth of the sulcus is 15-2cm. After the stepping is applied, a small amount of bio-fertilizer is used as the base fertilizer. The amount of fertilizer is 15-20kg per mu. The fertilizer was covered with a little soil, and the seeds were evenly sprinkled in, covering the soil with a thickness of 1-1.5 cm and slightly suppressing it. Use 0.5kg per acre.
Second, field management
When the temperature and humidity are normal, the seedlings are sown for 10-20 days, and when the height is 5cm, the seedlings are grown. Since the whole plant is harvested on the ground, it is not necessary to deliberately leave a single row, but the spacing between plants on each row should be maintained at about 10 cm to facilitate the branching and space needed for growth and development. The seedlings that come down can be transplanted again. Combine the grass with turfgrass, and properly perform rhizosphere soil cultivation. When the soil is too dry, it should be watered in time to ensure the normal growth of plants. Weeding is a regular part of field management. Preventing grass shortages is one of the effective measures to increase production; therefore, we need to make sure that weeds are removed and that weeds do not grow in the fields. During the rainy season, pay attention to the drainage of the field. After the rain, loosen the soil in time to prevent the top soil from binding and affect the growth of the plants. The loose soil not only increases the permeability of the soil, but also reduces the occurrence of diseases, and has the effect of doing more with less effort and achieving two goals at a time.
Third, leave the species
Good seeds are the basic conditions for achieving high yields. Therefore, seed fields should be established separately. Plant spacing 15-20cm, spacing 20-25cm. To strengthen field management, appropriate application of phosphorus and potassium fertilizer before flowering, so that the grain can be full to obtain more varieties. When 75%-80% of the seeds matured, the plants were cut off, placed in a well-ventilated shady place for 4-6 days, and then threshed; except for the net impurities and pods, dried for 3-4 days, and the seeds were loaded. Clean bags are placed in ventilated warehouses for planting in the following year.
IV. Pest control
According to the results of planting, no serious pests and diseases have been found. Only a long period of time in the field has root rot; therefore, timely drainage and soil loosening can be avoided. The drug control can be watered with 50% of carbendazim 500-600 times liquid root, and severely repeated once every 7-10 days.
Cosmetics are compound mixtures made from various raw materials after reasonable blending and processing. There are many types of cosmetics raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: base raw materials and auxiliary raw materials. The former is a main raw material of cosmetics, which occupies a large proportion in cosmetic formulations, and is the main functional substance in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other characteristics to cosmetics. These substances are not used in large amounts in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production processes such as heating, stirring and emulsification.
