How to choose a good wheat seed
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. High-quality wheat contains a certain amount of crude fiber and crude fat, and the content of crude fiber and crude fat in wheat can be determined by a crude fat analyzer or a fiber measuring instrument.
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 tend to use the new varieties of strains that have just been nurtured, have not undergone district trials and production test tests.
In the name of propaganda to farmers, some of them have even promoted a large number of “new varieties†or “exotic†varieties in the strains that have already been eliminated. As a result, the introduction of the strain resulted in a reduction in production or abolished production. In 1989, some people introduced the “American wolf tailed wheatâ€. The "Germany ton of wheat," which was introduced in 1993 as "Super Large Spike Wheat," was all frozen to death, causing major economic losses. This is a profound lesson.
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 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 promotion value, the competent department of seeds will take the initiative to review (recognize); as for some advertising campaigns, it is said that a variety has already been a scientific research unit ( Or the expert's appraisal or certification can't be used as a basis for promotion. Only the approval of the Crop Variety Approval Committee at all levels is the only legal review.
The second misunderstanding: Do not look at the scope of adaptation, blindly pursuing large-spike varieties. Large-spike wheat generally has greater potential for yield increase, but it does not mean that high-yielding wheat can be grown. Because wheat varieties are territorial, good varieties in the field may not be suitable for local planting conditions. For example, Super Big Spike Wheat 84 Plus (79)―3―1 has performed well in the Guanzhong area of ​​Shaanxi Province.
However, performance in other regions after introduction is not ideal.
Countermeasures: According to local production 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. The production may be based on the variety description “according to the map.†Non-seedling authorities often promote only when introducing varieties. Do not speak about the scope of adaptation, or even "do not choose
It is contrary to the laws of science and it must not be taken for granted. In addition, when introducing foreign varieties, we must insist on trial and promotion first so as 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 soil fertility. Only when planted with high-fertilizer land, high-fertilizer varieties can exert their potential for yield increase; if they are planted in low- and middle-yield fields, they often exhibit premature senescence, dryness, lack of grain, and low powder yield. Yield does not go up. 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.
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 is also necessary to use the introduction of the variety issued by the seed authority and cannot listen to the one-sided propaganda of the non-seedling authorities.
Misunderstanding 4: Only look at the output, not the quality. Wheat grain quality directly affects the economic benefits of wheat production, affecting 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.
Countermeasures: According to the recommendations of the seed authorities, comprehensive consideration of soil conditions, yield levels, and grain quality should be used to select high-quality wheat varieties with high yield and good quality.
