Wheat leaves are yellow and twisted, and there is little chlorophyll in the veins, which has just been watered? What is the reason
Because of the low greenhouse, less light and large temperature difference, it is necessary to spray natural brassinolide on the leaves in time, and apply humic acid active liquid fertilizer plus potassium dihydrogen phosphate plus triacontanol, or compound nitrophenol sodium plus amino acid active liquid fertilizer plus Xingpeng phosphorus potassium 1, and increase Lida light fertilizer once every 7~ 10 days for 2~3 times in a row to speed up the normal growth.
