Several foliar fertilizers sprayed in the late growth stage of wheat

Edible Gardening 0 views
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 1000-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 at the booting stage and once after heading and flowering, 7-10 milliliters per mu each time, plus 2% urea, diluted in 30 kilograms of water for spraying. It generally can increase the 1000-grain weight

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 1000-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 at the booting stage and once after heading and flowering, 7-10 milliliters per mu each time, plus 2% urea, diluted in 30 kilograms of water for spraying. It generally can increase the 1000-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-class seedlings. At the booting stage of wheat, use 100 milliliters per mu, add 30 kilograms of water, and spray. Do not mix-spray with pesticides or chemical fertilizers. Within 48@#@245@#@ before and after spraying pesticides, do not spray Huimanfeng.

3. Urea and potassium dihydrogen phosphate mixed solution. This is the earliest widely used foliar fertilizer, with effects such as supplementing nutrition, strengthening stalks 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 kilograms of water (5 kilograms of water for mist spraying) and spray.

4. Multi-element micro-fertilizer. According to the trace element content of the soil, reasonably prepare and spray it at the booting stage. It can reduce the degeneration of florets, increase the seed-setting rate, and increase grain weight.
