Dry and hot wheat is one of the agricultural severe weather. It can make the wheat dry, fried and mature, which will seriously affect the yield and quality of wheat. Therefore, strengthening the post-processing of wheat and taking appropriate measures in a timely manner can prevent the damage of dry hot air.
First, timely fill the water with sufficient grout. Grouting water is generally poured in the early stage of wheat filling ( about 2 to 3 weeks before the wheat harvest ). If the weather is dry and rainy in the early stage of wheat growth, the slurry should be poured early.
Second, spraying potassium dihydrogen phosphate. In order to increase the content of phosphorus and potassium in wheat straw and enhance the ability to resist dry hot air, a 0.2% to 0.4% potassium dihydrogen phosphate solution can be sprayed once in the booting, heading and flowering stages of wheat . Spray 50 to 75 kg per 667 square meters each time . It should be noted, however, that the solution cannot be applied in combination with an alkaline chemical.
Third, spray boron and zinc fertilizer. In order to accelerate the late development of wheat and enhance its resistance and firmness , 100 grams of borax can be added in 50 to 60 kilograms of water to spray during the flowering stage of wheat. When wheat or filling, spraying 50 to 75 kg of 0.2% solution of zinc sulfate per 667 square meters, can significantly enhance the resistance of wheat, and grain filling rate improved plumpness.
4. Spray naphthalene acetic acid. Spraying a concentration of 20 mg / kg naphthalene acetic acid during the flowering and filling stages of wheat can enhance the ability of wheat to resist dry heat.
5. Spray calcium chloride solution. During the flowering and filling period of wheat, a calcium chloride solution having a concentration of 0.1% can be sprayed , and the amount of liquid per 667 square meters is 50 to 75 kilograms.
6. Spray vinegar and acetic acid solution. For every 667 square meters, use 300 grams of vinegar or 50 grams of acetic acid , and spray 40 to 50 kilograms of water to spray wheat. 1 should each spray views booting and early filling, have a good effect on the prevention of dry hot wind.
