Wheat foliar spray fertilizer at the right time

Foliar spray application in the late growth stage of wheat is an important measure to extend the functional period of the leaves and maintain the root activity of the wheat, prevent premature aging, prevent dry hot air, promote grain filling, increase grain weight and improve grain quality. Foliar spray fertilizer is generally carried out from the booting stage to the middle stage of grouting. It can be used with about 2% urea solution (using 50 kg of urea per kg of water for 50 kg) or 200 g of potassium dihydrogen phosphate per acre for 50 kg of water. Spraying can also be combined with pest control to carry out root dressing, but it should be used with the use.
