Several foliar fertilizers sprayed in the later stage of wheat cropping
Spraying foliar fertilizer in the later stage of wheat can prolong the functional period of canopy leaves, promote the transport of photosynthates to grains, increase the number of full grains, improve 1000-grain weight and quality, and generally increase production by 5% to 10%. There are several kinds of foliar fertilizers commonly used:
1. Yemianbao contains humic acid and trace elements, which can enhance the stress resistance of wheat and supplement trace elements. Spray once at booting stage and after heading and flowering, each time 7 to 10 milliliters per mu, add 2% urea, spray 30 kg of water. Generally, the 1000-grain weight can be increased by 1 to 2 grams, and the yield can be increased by 5% to 6%.
2. Huimanfeng is prepared by many kinds of humic acid and many kinds of nutrient elements. it can activate the nutrient elements in the soil, promote the absorption of nutrients by crops, and provide nutrients directly, especially suitable for application on three kinds of seedlings. In the wheat booting stage, spray with 100 ml per mu and 30 kg of water. Do not spray with pesticides or chemical fertilizers, do not spray Huimanfeng within 48 hours before and after spraying pesticides.
3. Quiet element and potassium dihydrogen phosphate boiling solution, which is the earliest widely compatible foliar fertilizer, has the effects of supplementary nutrition, strong stem and anti-toppling, increasing grain weight and so on. After wheat heading and blooming, spray with 250 grams per mu, 100 grams of potassium dihydrogen phosphate and 40 kilograms of water (mist plus 5 kilograms of water).
4. According to the content of trace elements in soil, spraying multi-element micro-fertilizer reasonably at booting stage can reduce floret degradation, increase seed setting rate and increase grain weight.
