As the saying goes: "Seven-point, three-in-one", it is the key to grasp wheat preparation before sowing. We must strictly implement the "five-times-building, straw returning, scientific fertilization, deep-cultivation site preparation, and selection of superior seeds" five steps, which is an important measure for realizing a complete broadcast of seedlings. Specifically:
The first is to establish a timely basis. According to the meteorological department's forecast, due to the special weather factors of El Nino that occurred this year, it is likely to cause adverse meteorological conditions of “autumn drought and winter droughtâ€. According to this, before the wheat is sown, it is necessary to carry out all field arbitrage in order to achieve the purpose of “planting under full plantings and seedlingsâ€. In wheat sowing and licking, the licking is too early to be used to sow the whole planting of wheat; when it is too late, it not only delays the farming season, but also delays the sowing time of wheat, which is unfavorable for the formation of strong seedlings before winter. Therefore, the best ostrich time should be 10-15 days before the harvest of summer corn. At this time, the land is poured into water, which not only supplements the “white water†of corn, but also promotes the increase of corn yield. It also creates the preconditions for the timely planting of wheat.
The second is the mechanization of corn stalks directly back to the field. After corn matures and harvests, promptly do a good job of mechanization of corn stalks directly to the field. In the specific operation process, it is appropriate to use mechanical crushing of straw twice, and the length of crushing straw is about 3 cm. The straw smashed evenly, and no straw plucked in the field, laid the foundation for ploughing and soil preparation.
The third is scientific fertilization. Scientific fertilization is an important part of realizing the "rich in the fetus" of wheat. In order to prevent the contradiction between wheat rooting and straw decomposition, the high-nitrogen, medium-phosphorus, and low-potassium soil testing formula fertilizers should be vigorously promoted. The amount of mu is 50 kg, and the N:P:K ratio is 25:12:8. The content is 45%, and 1.5-2 kg of zinc fertilizer is added to the mu.
The fourth is to plough through the land. In the field of fine soil preparation, 50 kg of soil test formula fertilizer is spread on the surface evenly, deep plowing 20-25 cm, then rotary tillage 1-2 times, to achieve the virtual virtual reality, no light dark. If the soil is rotted alone, it should be turned twice and the depth should be about 20 cm. Rotary cultivation is too shallow, because of the large amount of straw in the field, it is easy to cause straw to get together, affect the quality of sowing, easy to form a lack of seedlings and ridges, it is difficult to achieve a complete broadcast seedlings.
The fifth is the selection of superior species. The best kind of suitable land is the key to achieve high yield and stable yield in wheat. The main wheat producing areas in our province, such as Rugao, Xingtai, Hengshui, and Quzhou, are mostly groundwater hoppers. In the selection of wheat varieties, those species that are resistant to drought, cold, water, and high-quality products should be used. At the same time, we must do so before sowing, promote post-harvest, increase the rate of emergence, and achieve Miao Qi, full, uniform and strong.
