At present, the application of chemical herbicides in agricultural production has been basically popularized. Some farmers' friends think that weeds have been removed after application of herbicides, and there is no need for cultivating. In fact, herbicides can only eliminate weeds and cannot replace cultivators. In addition to weeding, cultivators have many other important functions.
The first is to increase the aeration of dry crops such as wheat and rape to increase the aeration of the soil, increase the oxygen content in the soil, and increase the respiration and absorption capacity of the plant roots, thus making the crops flourish.
The second is to increase soil nutrient content
The organic matter and mineral nutrients in the soil must be decomposed by the soil microorganisms before they can be absorbed and utilized by crops. Most of the microorganisms in Tianzhong are aerobic due to dry farming. When the soil is not aerated and oxygen is insufficient, microbial activity is weak, and soil nutrients cannot be fully decomposed and released. After cultivating loose soil, the soil microorganisms are active due to the abundant oxygen, and they decompose and release the soil potential nutrients, thus increasing the utilization of soil nutrients.
The third is to adjust the soil moisture content in the drought when the cultivator, can cut off the surface of the soil capillary, reduce the transport of soil moisture to the soil surface and evaporation loss, improve the ability of the soil drought.
Fourth, increasing the soil temperature The cultivating loose soil can loosen the soil, increase the light receiving area, increase the ability to absorb solar radiation, weaken the heat dissipation capacity, and make the heat transfer to the deep soil layer quickly and increase the soil temperature.
The fifth is to suppress the deep cultivating when the crop grows too nutritiously in crops, which can cut off part of the root system, reduce the absorption of nutrients by crops, and curb their appetite. Sixth, soil-fertilizer blending and cultivating can stir the fertilizer applied on the surface of the soil to the bottom layer to achieve the purpose of blending soil and fertilizer. It can also promote ventilation, eliminate harmful substances in the soil, and prevent the occurrence of denitrification.
After chemical herbicides are applied, the time of cultivation in different crops is also different. Dry crops such as rapeseed, wheat, cotton and soybeans should be applied 20 to 25 days after spraying. Paddy fields should be applied 12 days after spraying, otherwise the effects of chemical weeding will be affected.
There are several main ingredients of Milk Replacer: 1. Plant protein - soybean meal, soybean protein concentrate, rice protein, potato protein and so on. 2. Milk protein - whey protein, casein 3. Sugar - lactose, glucose and other milk replacer powder is mainly the source of raw materials, a good milk replacer should have a high content of milk protein, lactose, and a high protein digestibility and palatability.
