It is the key to lay a good foundation for high yield of winter and spring wheat.

Henan Province is a major province of wheat production. in recent years, the state and province have issued a series of policies to benefit farmers to support the development of wheat production, so that the agricultural production conditions of our province have been greatly improved and the production level has been continuously improved. the total yield and per unit yield of wheat have reached an all-time high for five consecutive years. The sown area of wheat reached 75.66 million mu in 2007, and the sown area of wheat will be further expanded in 2008. Doing well wheat sowing is the basis of high and stable yield of wheat. First of all, the selection of varieties, only the selection of good varieties, increase production can be guaranteed. The second is the detailed work of soil preparation, fertilization, watering and sowing. Only by making fine soil preparation, applying base fertilizer, making good soil moisture and sowing at the right time can we ensure the whole seedling and lay a good foundation for high yield in the following year. The last is the prevention of wheat diseases, insect pests and weeds. Sowing date is the key period for the prevention of many kinds of wheat diseases, insect pests and weeds. Doing a good job in the prevention of diseases and insect pests during sowing period can not only directly and effectively control the harm of underground pests and weeds, but also effectively control the occurrence of many diseases in the early stage of wheat growth, reduce the occurrence degree and reduce the pressure of control in the later stage. This year's wheat sowing work is about to begin. In order to strive for wheat production to reach a new high, we have specially consulted the provincial seed management station, relevant experts of Henan Agricultural University, and some grass-roots agricultural technicians to introduce practices from the aspects of variety selection, soil preparation, sowing, fertilization, and prevention of diseases and insect pests during sowing, so as to ensure that the whole seedling can be sowed in one sowing, so as to achieve the goal of evenness, evenness and strength of seedlings, and lay a good foundation for the high yield of wheat in the following year. The guiding ideology for the utilization of autumn sowing wheat varieties this year is to take high and stable yield varieties as the leading role, focus on high-quality special varieties, conscientiously do a good job in layout planning, select varieties according to local conditions, and achieve the combination of improved varieties and good methods. In terms of variety distribution, the general principle is to reasonably adjust the proportion of semi-winter varieties and weak spring varieties, mainly semi-winter varieties in the northern wheat region, weak spring varieties in the late stubble, and weak spring varieties in the central and southern wheat region, early stubble with semi-winter varieties. For varieties participating in this year's subsidies for improved varieties, we should still adhere to the principle of "recommendation by experts, recognition by the market, welcome by the masses, promotion of excellence rather than one-sided pursuit of innovation and differences," and fully respect the wishes of farmers. the high-quality and high-yield varieties that have been approved and tested and demonstrated are identified as the leading local varieties to ensure the safety of seed use in the field.
