High-quality strong gluten wheat soil testing formula fertilization technology is a fertilizer operation technology based on soil testing and fertilizer field experiment. It is the main content of scientific fertilization of high-quality strong gluten wheat, which can improve fertilizer utilization rate and achieve low consumption and high efficiency. Promote sustainable development of agriculture.
I. Soil testing formula Fertilization principle According to different fertility conditions and strong nitrogen content of strong gluten wheat, strong ability of nitrogen absorption in the middle and late period, and rapid nitrogen conversion, the principle of soil fertility formula for high-quality strong gluten wheat is proposed: Due to the lack of supplements, the application of organic fertilizer, rational application of phosphorus and potassium micro-fertilizer, the implementation of the former nitrogen shift, staged topdressing, late application of foliar fertilizer.
Second, the fertilization technology points 1. Apply enough base fertilizer. According to the fertility level and the target yield, the amount of fertilizer is determined, and the fertilizer is combined with the organic fertilizer. About 500 kilograms per mu of land, about 4 yuan of organic fertilizer, 7-8.5 kilograms of pure nitrogen, 6-8 kilograms of phosphorus (P2O5), 6--9 kilograms of potassium (K2O) (40--50 carbon ammonium equivalent) Kg, superphosphate 50--60 kg, potassium chloride 10--15 kg), zinc sulphate 1.5 kg; about 400 kg per mu of land yielding more than 4 organic fertilizers, 7 kg of pure nitrogen (carbon ammonium) 40 kg), phosphorus (P2O5) 5--7 kg (45-55 kg of superphosphate), potassium (K2O) 6 kg (10 kg of potassium chloride). The straw is returned to the field, and the corn stalk is directly returned to the field at 1:2, that is, the corn stalk of one mu of land is smashed and then cultivated in 2 mu of land.
2. Staged topdressing: adopting the technology of nitrogen fertilizer post-shifting, that is, changing the water to the green water for the water-saving, and changing the green fertilizer to the jointing fertilizer. The first top dressing should be carried out at the jointing stage, combined with watering acres to chase urea about 15 kg, the second top dressing should be carried out in the flag-flowering period, combined with watering acres to chase urea 3--5 kg. At the initial stage of grain filling, spray 1-2% urea solution 50-60 kg/mu, and spray again after 7 days. Strong gluten wheat leaves sprayed with trace elements such as boron and zinc, which can increase grain protein content and wet gluten content, while delaying aging and increasing grain weight.
In addition, wheat milk is ripe until the harvesting stage, and watering must be strictly controlled. If it is not dry, it is generally not watered. If it is too dry and needs watering, it should be watered before and after 10 days of flowering to prevent watering of wheat or yellow water.
