When the students from the Small Institute of Science and Technology met with Chang Geyi, a large planter, he asked: Why do the hundreds of acres of wheat that my family planted last year give a “scrape†at the end of May with a gust of wind?
This is often said that wheat has suffered from dry hot winds. The dry hot wind of wheat refers to the meteorological disasters caused by droughts and high temperatures in wheat at the late stage of childbirth, or accompanied by strong winds, or sudden high temperatures after rain, which can cause the wheat to fail to mature normally. The damage of dry hot winds is mainly in the middle and late May, that is, wheat. The middle and late stages of grouting.
The following measures can be taken for wheat exposed to dry hot wind:
First, pour grouting water in the initial stage of grouting (2-3 weeks before wheat harvest). For example, early drought and less rain in wheat can be advanced.
Second, in the booting, heading and flowering stage, each spray a 0.2% -0.4% potassium dihydrogen phosphate solution, each time 50-75 kilograms per mu, in order to increase the phosphorus content of wheat straw, and enhance the ability to resist dry hot wind. However, it should be noted that this solution cannot be mixed with alkaline chemicals.
Third, in order to accelerate the late development of wheat and enhance its stress resistance and firmness, 100 grams of borax can be added to 50-60 kilograms of water to spray on wheat during the flowering period. Or when wheat is grouted, spray 50-75 kg of 0.2% zinc sulfate solution per acre.
Fourth, in the flowering and filling stages of wheat, naphthalene acetic acid was sprayed at a concentration of 20 mg/kg.
5. During the flowering and grain filling period of wheat, spray 0.1% CaCl2 solution at a concentration of 50-75 kg per mu.
Sixth, 300 grams of vinegar per acre or 50 grams of acetic acid, add water 40-50 kilograms, in the booting and the initial stage of each grouting 1 spray.
