Every year before the wheat is sown in autumn, many farmers' friends have insufficient understanding of the selection of wheat varieties because of the limited conditions. It is easy to go into the wrong zone. Remind farmers here: When shopping for wheat, pay attention to “Four Don’tsâ€.
One is not to seek new ones for new varieties. It refers to multi-year inspections after regional trials and production trials, and has been examined (recognized) by the Provincial Crop Variety Approval Committee, and has produced excellent varieties in terms of yield, quality, and resistance. However, some units and individuals on the market tend to advertise and promote new strains that have just been cultivated without regional trials and production trials in the name of new varieties. This should be taken as a warning.
The correct approach is to purchase the approved species. The seed management department must carry out rigorous regional trials and production trials before the certification and promotion of varieties, and generally ensure that high-yield and stable production can be ensured through purchase of certified varieties. Unrecognized strains can only be used as a trial species or demonstration, and they must not be widely promoted as a major species. As for some advertisements, it is said that a certain species has already been identified or recognized by a scientific research unit (or expert) and cannot be used as a basis for promotion. The examination and verification of the Crop Variety Approval Committee at all levels is the only legal review.
Second, do not blindly pursue the large-spike varieties. Large-spike wheat generally has a large potential for yield increase, but it does not mean that the cultivation of large-ear wheat will certainly yield high yields. Because wheat varieties have regional characteristics, good varieties in different places do not necessarily adapt to local planting conditions.
Correct practice strictly examines the scope of adaptation of the species based on local production ecological conditions. Before the autumn broadcast every year, the agricultural management department publicly recommends a batch of wheat improved varieties for farmers to choose; if the promotion of the varieties only talk about promotion, do not talk about adaptation, this is contrary to the laws of science, do not believe. In addition, when introducing foreign varieties, it is necessary to insist on trials and promotion afterwards.
Third, do not unilaterally pursue high-fertilizer varieties. Each variety has its own adaptability to land-level. High-fertilizer varieties can only exert their potential for yield increase if they are planted on high-fertilizer land; if they are planted in low- and middle-yield fields, they often exhibit premature aging, dryness, and insufficient grain. , low yield, etc., the output 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.
The correct approach is based on the conditions of the soil, and choose the species that are compatible with the level of yield. When examining the yield level of a variety, the same shall be based on the introduction of the variety issued by the agricultural management department.
Fourth, do not only look at the output, do not look at the quality of wheat grain quality is directly related to the economic benefits of wheat production, 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.
Correct practice
According to the recommendations of the agricultural management department, comprehensive consideration of soil conditions, yield levels and grain quality, selection of high-quality wheat varieties with high yield, good quality, and strong resistance.
