Winter wheat from the heading to the filling stage, often encountered dry hot wind invasion, dry hot wind will make the wheat plant withered, can not normally mature grain filling, wheat grain empty, reduced grain weight, yield reduction up to 10% -30%.
Spraying potassium dihydrogen phosphate from heading to milk ripening stage, phosphorus and potassium nutrition absorbed by wheat leaves can accelerate the synthesis, transportation and accumulation of dry matter, make adequate grain filling, accelerate grain filling, and significantly increase grain weight. Promote the role of maturity, thereby reducing the harm of dry hot wind. For the later wheat plants with more nitrogen nutrition, spraying potassium dihydrogen phosphate may accelerate the synthesis and accumulation of dry matter. Therefore, there are certain benefits to grouting and strengthening. The year when dry hot wind does not occur can also increase production. Potassium dihydrogen phosphate concentration 0.2% is appropriate, spray 100 pounds of fertilizer per acre, about 100 grams of medication, spray fertilizer time to heading and flowering period is better, the effect of spraying once again during the filling period is better, twice the interval of 10-15 days .
