To a great extent, this happened because rural labor migrated to cities, farmers learned to put down their shovels and set up a large number of companies in big cities, such as vegetable and fruit enterprises and fresh fruit production and processing enterprises, which created a large number of jobs for farmers, attracted farmers who worked outside the home to return to the countryside, and of course reduced the barren land resources. No one can grow crops, but good land will become inaccessible. My father's family has more than half an acre of land. Because I was old, I was left unattended in farming and stayed there for two years.
Human weeding is low-carbon and environment-friendly, without using organic chemical herbicides and pesticide residues. Moreover, there is a soft soil layer at the root of wheat, which can moisturize and replenish water and promote growth, killing two birds with one stone. Although human weeding is emerald green, everyone has high labor efficiency and low productivity. The sun in early spring is not poisonous, and some cut weeds can't dry at all. The grass here has just been hoed, and the grass there is alive again. Everyone is busy, but the grass shortage has not been dealt with. So now the agricultural ecology is relatively developed, and weeding with wheat herbicide is basically once and for all. Weeding actually works well. Herbicide can only be used for weeding after germination of spring wheat. For the excavated weeds, this temperature will wake up the body cells, institutions and sensory system software. This temperature is also suitable for the growth of most plants in nature Green plants and small animals living in nature have their own biological clocks, and they rest or exercise at a certain stage.
When small animals rest, their bodies are basically at rest. Your body will look different if you take active exercise. As we all know, this overgrown green plant seems to be in a state of stagnation when resting or exercising. However, there are various physiological human organs, somatic cells and institutions in their bodies, and the transmission system software has been coordinating their growth and development. When the outside temperature is suitable for their theme activities, all kinds of organs in their bodies gradually become active, as do all kinds of human organs in leaves and stems, and the air outlet is open to the outside world, digesting and absorbing natural nutrients and spreading to all parts of the body. Therefore, if the herbicide is sprayed at this temperature, the ingredients in the herbicide will be digested and absorbed by them. Only in this way can we achieve the best practical effect of weeding. The basic principle of herbicide weeding: the pharmacology of herbicide killing weeds is: contact killing and stomach killing: contact killing refers to spraying herbicide aqueous solution on weeds when it contacts weeds, and it can kill weeds after being digested and absorbed into the body. Contact killing and stomach killing are components of the same pharmacological herbicide, and their molecular structure will be more active.
When they enter weeds, they will quickly destroy somatic cells and mechanisms in weeds and disrupt their conventional delivery system software. All kinds of human organs in Weeds are hemiplegic, declining and finally withering. Wheat herbicides can be divided into Gramineae herbicides and broadleaf herbicides: Gramineae herbicides: professional weed control. Gramineae weeds refer to monocotyledonous weeds, that is, small-leaved green plants with small stems for growing seedlings. Although wheat is a crop planted by everyone, it is also a grass green plant. The most common weeds in Gramineae are wild oats, Aegilops tauschii, Spatholobus suberectus roots and Sophora alopecuroides seedlings. Suitable herbicides for spraying gramineous weeds in wheat fields are fenoxamide and propargyl. The design scheme is used to eliminate weeds of broadleaf plants and grasses. It is also a dicotyledonous weed. The most common big-leaf weeds are bitter purslane, bitter wax and purslane. Herbicides used to kill these weeds include bensulfuron-methyl and flufenoxuron.
