Is the period of spraying foliar fertilizer on corn related to the amount of water?

Foliar fertilizer can be sprayed when maize encounters diseases and insect pests, or when the soil is too acidic, alkaline and salinity, and in the full fruit stage, the plant suffers from air damage, heat injury and freezing injury. Spraying foliar fertilizer on corn has something to do with the amount of water. Generally, 10% plant ash water, 10% chicken manure, 10% Rue 20% rabbit manure or mature human urine should be added when spraying fertilizer outside the root.

I. the period of spraying foliar fertilizer on corn

The main results are as follows: 1. Foliar fertilizer can be sprayed when maize encounters diseases and insect pests, which is beneficial to improve plant disease resistance, or when the soil is too acidic, alkaline and salinity is too high, foliar fertilizer is sprayed when the plant absorbs nutrients.

2. In the full fruiting period, after the plant suffered from air injury, heat injury and freezing injury, foliar fertilizer can also be sprayed at an appropriate time, which is helpful to alleviate the symptoms.

Does spraying foliar fertilizer on corn have anything to do with the amount of water?

1. The application of foliar fertilizer to corn has something to do with the amount of water. Generally, the suitable concentration for spraying is urea 0.5% Mel 2%, ammonium sulfate 0.2% Mel 9.3%, potassium dihydrogen phosphate 0.3% Mel 0.5%, ammonium molybdate 0.01%, borax 0.1% Mel 0.2%, Zinc Sulfate 0.1% Mel 0.4%.

2. Generally, when spraying fertilizer outside the root, it is necessary to add 10% plant ash water, 10% chicken manure, 10% Murray 20% rabbit manure or mature human urine, which will have an obvious effect on increasing production.

Third, the effect of spraying foliar fertilizer on corn.

1. Promote growth

As the foliar fertilizer is composed of trace elements, spraying can comprehensively supplement nutrients and help to improve the growth rate of crops.

2. Control the growth

Corn stalk growth stage is prone to excessive growth, crazy growth and other phenomena, so it is necessary to absorb a large amount of nutrients in the soil, so that corn can not get sufficient nutrition at the ear-setting stage.

3. Increase the yield per plant.

Spraying foliar fertilizer can promote the healthy growth of corn ear, significantly improve the ear saturation and avoid the phenomenon of empty ear.

4. Improve disease resistance.

The disease of maize is partly due to the lack of nutrients, which can easily lead to the decline of maize resistance, so timely application of foliar fertilizer can enhance the stress resistance of maize and promote the healthy growth of maize.

IV. Spraying skills and matters needing attention

The main results are as follows: 1. when foliar spraying, it is generally mainly on the back of the leaf, because the back has more stomata than the front, which is helpful to improve the nutrient absorption rate.

2. Foliar fertilizer can not be sprayed at the flowering stage or seedling stage, because the flowering stage is fragile, improper fertilization will easily cause fertilizer damage and reduce the yield of maize, and the seedling stage is not suitable for spraying, because the base fertilizer can fully supply the nutrition of maize at the seedling stage.

3. when spraying foliar fertilizer, it is necessary to avoid high temperature weather. In order to reduce foliar evaporation and improve absorptivity, it is necessary to avoid high temperature and rainy weather.
