Spring cultivation should avoid four errors

Crops produce high yields, and thoroughbreds are the key. 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.

One of the errors: One-sided innovation, curiosity. 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 varieties”. "Or "special" varieties of a large number of sales, the results lead to reduced production or out of production.

Countermeasures: Purchase of approved varieties. 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.

The second misunderstanding: Do not look at the scope of adaptation, 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.

Countermeasures: According to local production ecological conditions, strictly examine the range of adaptation of the species. 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 map”; 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.

Misunderstanding 3: Do not look at land conditions, one-sided pursuit of 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.

Countermeasures: According to the conditions of the land, select the species that are suitable for the level of yield. 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.

Misunderstanding 4: Only 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.

Countermeasures: According to the recommendation of the seed authorities, comprehensive consideration should be given to soil conditions, yield levels, and grain quality to select crop varieties with high yield and good quality.
