Several foliar fertilizers suitable for spraying in the late growth stage of wheat

Spraying foliar fertilizers in the late stage of wheat cultivation can extend the functional period of canopy leaves, promote the transport of photosynthates to the grains, increase the number of filled grains, and raise the thousand-grain weight and quality, generally increasing yield by 5%-10%. The commonly used foliar fertilizers include the following:

1. Yemianbao contains humic acid and trace elements, which can enhance the stress resistance of wheat and supplement trace elements. Spray once each at the booting stage and after heading and flowering, 7-10 milliliters per mu each time, plus 2% urea, diluted in 30 kg of water for spraying. It can generally increase the thousand-grain weight by 1-2 grams and increase yield by 5%-6%.

2. Huimanfeng is made from various humic acids and multiple nutrient elements. It can activate nutrient elements in the soil, promote crop absorption of nutrients, and directly provide nutrients. It is especially suitable for application on third-category seedlings. At the booting stage of wheat, use 100 milliliters per mu, add 30 kg of water, and spray. Do not mix-spray with pesticides or chemical fertilizers. Do not spray Huimanfeng within 48@#@245@#@ before or after spraying pesticides.

3. Mixed solution of urea and potassium dihydrogen phosphate. This is the earliest and most widely used foliar fertilizer, with effects such as supplementing nutrition, strengthening stems to prevent lodging, and increasing grain weight. After wheat heading and flowering, use 250 grams of urea and 100 grams of potassium dihydrogen phosphate per mu, add 40 kg of water (5 kg of water for mist spraying), and spray.

4. Multi-element trace fertilizer. According to the trace element content of the soil, rationally prepare and spray at the booting stage, which can reduce floret degeneration, increase the seed-setting rate, and increase grain weight.
