What issues should pay attention to buy wheat?

Wheat produces high yields, and improved varieties are the key. Every year on the eve of autumn, many peasant friends ask friends and friends around the world to look for wheat varieties in order to have a good harvest in the coming year. However, due to the limited conditions, many farmers do not know enough about the wheat varieties, and it is easy to go wrong in the selection of varieties and bring undue losses to production. What problems should be paid attention to when purchasing wheat seeds?

First, do not seek new ones and seek novelty. Generally speaking, new varieties refer to multi-year inspections after regional trials and production trials. They are reviewed by the Provincial Crop Variety Approval Committee and are excellent in terms of yield, quality, and resistance. Variety. 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" a large number of "special" varieties of sales, the results lead to reduced or absolute production after the introduction; in 1989, some people introduced "American wolf tail wheat", "Germany, tons of wheat", introduced in 1993 "super large spike wheat" and all were frozen, The major economic loss is a profound lesson.

The right approach: buy the species that passed the trial (recognition). 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.

Second, do not blindly pursue the large-spike varieties. Large-spike wheat generally has greater potential for yield increase, but it does not mean that large-ear wheat can be produced with high yield. Because wheat varieties are territorial, good varieties in the field may not be suitable for local planting conditions.

The right approach: According to the production of ecological conditions, strictly examine the range of adaptation of the species. Every autumn, the competent department of seeds must publicly recommend a batch of wheat varieties through newspapers and other news media for use by various localities. According to the varieties, the competent department of seeds can introduce “according to maps and maps”; non-seedling authorities often promote only when introducing varieties. Do not talk about the scope of adaptation, or even "do not select the climate, do not choose the soil", which is contrary to the laws of science, do not believe. In addition, when introducing foreign varieties, it is necessary to insist on trials and subsequent promotion in order to avoid losses.

Third, do not unilaterally pursue the high-fertilizer varieties that have their own adaptive soil fertility levels. High-fertilizer varieties can only exert their potential for yield increase if they are planted in high-fertilizer lands; if they are planted in low-yielding fields, they often exhibit premature aging, dryness, and grain. Insufficiency in output, low yields, etc., can't be achieved. In the same way, Chinese fertilizer and dry land varieties are planted on high-fertilizer lands, because their yield-increasing potential is limited, and they tend to fall down, and their yields do not increase.

The right approach: According to the conditions of the soil, select the species that are compatible with the level of yield. When examining the yield level of a variety, it is also necessary to use the introduction of the variety issued by the seed authority, and it is impossible to listen to the one-sided propaganda of the non-seedling authorities.

Fourth, don't just look at the yield, not the quality of wheat. The direct economic benefits of wheat production will affect the quality of flour and its products and the benefits of the food industry. However, when selecting wheat varieties in many places, they often only look at the level of production and do not look at the quality indicators. When the results are produced as commercial grain, the price of the wheat varieties is much worse than that of high-quality wheat.

The right approach: According to the recommendations of the seed authorities, comprehensive consideration of soil conditions, yield levels and grain quality, selection of high yield, good quality wheat varieties.
