Spring sowing seeds
On the eve of spring broadcast every year, many farmers and friends ask friends and friends to look for good crops in order to have a good harvest in autumn. However, due to the limited conditions, many farmers do not know enough about the variety of crops. It is easy for them to go wrong in the selection of varieties and bring undue losses to production. The following gives you a description of the correct way to choose the species. Hair loss is the phenomenon of hair falling out. The hair that normally falls off is the hair in the degenerative and telogen phase. Since the hair entering the degenerative phase and the newly entering the growing phase are constantly in a dynamic balance, the normal number of hairs can be maintained. Pathological alopecia refers to abnormal or excessive hair loss, which can have many causes.

1. Be careful not to revive one-sidedly. New varieties generally refer to multi-year inspections after regional trials and production tests, and have been examined (recognized) by the Provincial Crop Variety Approval Committee, and have been excellent in terms of yield, quality, and resistance. However, in the market, some units and individuals often propagate the strains that have just been nurtured, have not undergone district trials and production test tests to farmers in the name of new varieties, and some even have eliminated the strains as “new varietiesâ€. "Or "special" varieties of a large number of sales, the results lead to reduced production or out of production.
The correct course of action is to purchase the varieties that have passed trials. The competent department of seeds must carry out rigorous regional tests and production trials before the certification and promotion of varieties, and the varieties purchased through approval can generally ensure high yields and stable production. Unqualified strains can only be used as collocation varieties for trials or demonstrations, and must not be widely promoted as headlines. For the so-called "special breeds," do not buy or introduce products. Because the breeds that really have value promotion, the seed authorities will take the initiative to review (recognize) them; as for some advertisements, it is said that a variety has already been a scientific research unit ( Or the expert's appraisal or certification cannot be used as a basis for promotion. Only the approval of the Crop Variety Approval Committee at all levels is the only legal appraisal.
2. Look at the scope of adaptation. Do not blindly pursue high-product varieties. High-yielding species generally have greater potential for yield increase, but it does not mean that high-yielding crops will necessarily produce high yields. Because the crop varieties are territorial, good varieties in the field may not be suitable for local planting conditions.
The correct approach is: According to the local production of ecological conditions, strict examination of the scope of adaptation of varieties. Before spring sowing each year, the agricultural department must publicly recommend a batch of crop varieties through newspapers and magazines for local use. The production can be based on the variety description “according to the mapâ€; and some profit-oriented units and individuals are often recommending varieties. Only speaking about promotion, not talking about the scope of adaptation, or even saying, "Do not choose the climate, do not choose the soil." This is contrary to the laws of science, and do not believe. In addition, when introducing foreign varieties, it is necessary to insist on trials and subsequent promotion in order to avoid losses.
3. Pay attention to the conditions of land, do not unilaterally pursue high-fertilizer varieties. Each species has its own adaptability to the level of soil fertility. High-fertilizer varieties can only exert their potential for yield increase if they are planted on high-fertilizer lands; if they are planted in low- and middle-yield fields, they often exhibit premature aging and low yields and instability. In the same way, medium and low-fertilizer varieties are planted on high-fertilizer plots. Because of their limited potential for yield increase, they tend to fall down and their yields do not increase.
The correct approach is: According to the conditions of land, select the species that are in line with the level of production. When examining the yield level of a variety, it must be based on the introduction of the variety issued by the seed authority, and can not listen to the one-sided propaganda of the non-seedling authorities.
4. Note that you can't just look at the output, not the quality. When many farmers choose their crop varieties, they usually only look at the level of production, do not look at the quality indicators, and end up increasing their output without increasing income.
The correct approach is: According to the recommendations of the seed authorities, comprehensive consideration of soil conditions, yield levels and grain quality, select high yield, good quality crop varieties.
