Can you spray foliar fertilizer on corn when it s dry?

Try to choose windless and sunny weather corn growth period has a greater demand for nutrients, good fertilization management can effectively improve the yield of corn per plant, and at the same time can reduce the occurrence of diseases, so when is the best spraying effect of corn foliar fertilizer? What are the issues that need to be paid attention to when applying foliar sprays to improve fertilizer efficiency? First of all, let's talk about the effects of corn foliar fertilizer spraying, so as to better understand the spraying time:

1. Promote growth, because the foliar fertilizer is composed of trace elements, spraying can comprehensively supplement nutrients and improve the growth rate of crops. 2. Controlling the growth of the corn stalk, the corn stalk will grow and grow wildly during the growth period, absorbing a large amount of nutrients in the soil, so that the corn can not get sufficient nutrients at the earing stage. 3. To increase the yield per plant, spraying foliar fertilizer can promote the healthy growth of corn ears, improve the saturation of corn ears, and prevent empty ears.

Spraying foliar fertilizers such as Fatham amino acids can be applied on any crop. 4. Improve disease resistance, part of the reason for corn disease is insufficient nutrients, resulting in decreased resistance, etc., foliar topdressing can enhance stress resistance growth and provide disease resistance. Corn foliar fertilization time 1, 3-5 days before corn tasseling, corn tasseling is the critical period of fertilization, corn ears begin to grow after tasseling, that is, the fruiting period, 3-5 days ago, comprehensive supplementation of nutrients can effectively achieve the purpose of increasing yield.

2. When encountering pests and diseases, spraying foliar fertilizer after corn has diseases and insect pests can alleviate the symptoms, restore growth and reduce losses. 3. When the soil acid-base is unbalanced, the soil acid-base imbalance can be sprayed with foliar fertilizer, which adds humic acid and other components, which can improve the soil environment and balance the pH value. 4. Earing stage, corn earing stage is the period with the most nutrient demand in the whole growth period, and spraying can effectively increase the weight of each corn ear pellet.

Spraying skills and precautions 1. Foliar spraying should be mainly on the back of the leaf, and the back stomata should be excess on the front, which can improve the nutrient absorption rate. 2. Foliar fertilizer can not be sprayed at the flowering and seedling stage of corn, the flowering period is fragile, improper fertilization will cause fertilizer damage, reduce yield, and the seedling stage is not suitable for spraying, because the bottom fertilizer has been fully supplied for the growth of corn seedlings. 3. Avoid high temperature weather, in order to reduce foliar evaporation and improve the absorption rate, high temperature and rainy weather should be avoided.

*Foliar fertilizer can be sprayed on corn when the weather is dry**.

It should be noted that when spraying foliar fertilizer, it is necessary to spray the leaves and roots, and this method can be used if there is no irrigation condition. At the same time, if you encounter a drought situation and cannot apply fertilizer, you need to chase urea when it is about to rain, or dig a pit and drip water to top dress.

Functions of foliar fertilizer for corn:

Regulate plant height, prevent lodging, promote early maturity, increase and extend corn pollination, prevent empty trees, speed up the corn cob tip grain fullness, prevent bald tips, and comprehensively lengthen the length of the cob ear, etc., It can also greatly increase the weight of 1000 grains, increase production and income by more than 300 catties. And it also solves the disadvantages of shrinking joints and rods of other dwarf products such as arthrothylamine and paclobutrazol.

Precautions for spraying:

Corn foliar fertilizer spraying should generally be carried out 3 5 days before corn tasseling, generally with 2 bottles of Fulvi 655 or Fulvico foliar fertilizer per hectare sprayed on the top leaves of corn.

Some trace element fertilizers such as borax are not easily soluble in cool water and are only easily dissolved when the water temperature is above 40. When preparing the borax solution, it should be dissolved with a small amount of warm water and then diluted to the required concentration with water, so that the fertilizer solution can be uniform.

The spraying time should generally be selected in the morning of a sunny day or after 4 p.m. without wind, or you can choose cloudy weather, so that the longer the solution is moistened on the leaves, the better.

Period when foliar fertilizer needs to be used:

1. When encountering pests and diseases, the use of foliar fertilizer is conducive to improving plant disease resistance;

2. When the soil is acidic, alkaline or salin, which is not conducive to the absorption of nutrients by plants;

3. Full fruit period;

4. After the plant encounters air damage, heat damage or frost damage, choosing the right time to use foliar fertilizer is conducive to alleviating the symptoms.

Spray with water, pay attention to the concentration should not be too large...

You can use special foliar fertilizer for corn, or you can use the concentrated phosphorus and potassium essence of Demer Tianye, the effect is very obvious, you can give it a try.

Summary. Hello! Foliar fertilizers at the seedling stage of corn commonly use potassium dihydrogen phosphate, potassium sulfate, zinc sulfate, copper sulfate, brassinolide, etc.

The bottom fertilizer at the seedling stage is sufficient, and the corn seedlings generally do not lack fertilizer, and the need to spray foliar fertilizer is the herbicide pesticide, and the other is after the damage of pests and diseases. Before corn sowing, it is necessary to play closed herbicides, some herbicides have a long half-life, after corn emerges, resulting in corn wilting, yellow leaves, red leaves, white leaves, at this time, potassium dihydrogen phosphate, brassinin lactin should be sprayed to regulate corn to restore growth, reduce herbicide damage, promote corn to restore normal metabolism, respiratory circulation, transpiration photosynthesis, and promote corn chlorophyll production. The corn production cycle can be foliar spray potassium dihydrogen phosphate and brassinin 3 times.

300 grams of 98% potassium dihydrogen phosphate + 20 grams of brassinolide mixed with water 30 kg of foliar spray each time. Spraying potassium dihydrogen phosphate and brassinolide at the seedling stage can effectively prevent crude shrinkage.

Before corn sowing, it is necessary to play closed herbicides, some herbicides have a long half-life, after corn emerges, resulting in corn wilting, yellow leaves, red leaves, white leaves, at this time, it is necessary to bridge the trap spray potassium dihydrogen phosphate and brassinin lactin to regulate the recovery of corn growth, reduce herbicide damage, promote corn to restore normal metabolism, respiratory circulation, transpiration photosynthesis, and promote the production of corn leaf green orange polyphyton. The corn production cycle can be foliar spray potassium dihydrogen phosphate and brassinin 3 times. 300 grams of 98% potassium dihydrogen phosphate + 20 grams of brassinolide mixed with water 30 kg of foliar spray each time.

Spraying potassium dihydrogen phosphate and brassinolide at the seedling stage can effectively prevent crude shrinkage.

The seedling stage suffers from pests and diseases, and at the same time of using fungicides and insecticides, potassium dihydrogen phosphate and brassinolide can be sprayed. At the seedling stage, trace elements such as copper sulfate, zinc sulfate, potassium sulfate and other trace elements can be sprayed on the foliar surface, which can enhance the immunity and stress resistance of corn, and copper sulfate has a bactericidal effect and has an inhibitory effect on corn virus. Corn seedlings can be sprayed with 10% potassium sulfate, 10% zinc sulfate mixed with 30 kg of water solution, copper sulfate, boron fertilizer can be diluted twice, sprayed with 30 kg of water.

Foliar spray urea can be used at the seedling stage of corn, in the case of nitrogen deficiency fertilizer, but for nitrogen, phosphorus, and potassium tolerant fertilizer, it is best to apply it under the roots. Corn is a potassium-loving spring crop, in the seedling stage can be foliar imitation residual spray high concentration potassium fertilizer and water-soluble nitrogen fertilizer, can promote the stalk thick, the root system is developed, lodging resistance, drought resistance, farmers usually foliar spray potassium dihydrogen phosphate, brassinolide lipid more. The growth cycle of corn mainly depends on bottom fertilizer and top dressing.

The growth of corn seedlings is weak, and the soil moisture is not good, so it is necessary to spray foliar fertilizer to enhance corn immunity and stress resistance, but there are few cases of foliar spraying foliar fertilizer at the seedling stage in actual production management, and foliar fertilizer is sprayed more before maize tasseling to the male and female differentiation stage. Late premature senescence of corn can also be sprayed with foliar fertilizer.

Summary. Hello has helped you to inquire: corn post-emergence herbicide spray can be sprayed 3-5 days after spraying.

When spraying foliar fertilizer, it is necessary to pay attention to controlling the dosage to avoid excessive fertilization and affect the growth and development of corn seedlings. Foliar fertilizer spraying can provide necessary nutrients for corn seedlings to promote their growth and development.

I sprayed Ye Yu fertilizer yesterday, and I'm going to spray herbicide again today, is it okay?

I sprayed foliar fertilizer yesterday, can I spray herbicide today?

In order to better absorb and effect, it is best to wait for 3 days!

Summary. Dear, I'm glad to answer for you: Corn post-seedling herbicide spray can be sprayed a few days after spraying: 2 weeks after herbicide spray 14 days after spraying can spray foliar fertilizer Oh kiss helps growth.

Dear, I'm glad to rent your answer: guess the mold corn seedlings after weeding ear retardant spray a few days after spraying foliar fertilizer: 2 weeks after the herbicide spray 14 days after the spray can spray foliar fertilizer Oh kiss helps growth.

Corn needs nitrogen fertilizer to maintain soil fertility during the flowering stage, after the stamens are silked, and a certain amount of water is needed to replenish the rolling silver. During the kernel stage, the kernels and corn seeds will gradually rot and form, so a second irrigation can be carried out after the milk maturity stage, but the amount of irrigation needs to be controlled in the right amount. In the rainy season, to avoid excessive moisture and harm to corn, it is necessary to do a good job of slowing down leakage and drainage, and at the same time strictly control some pests and diseases, which can be achieved by using 95% CommScope No. 6 and potassium dihydrogen phosphate.

My corn seeds are seven-leaved and eight-leafed, and after a few days of herbicide, I can apply foliar fertilizer.

14 days after the herbicide is applied, you can apply foliar fertilizer, oh kiss <>

Can't you fight after three days.

It is not recommended to hit it after three days, oh kiss, the herbicide has not been completely diluted, and the foliar fertilizer cannot absorb much.

You can fight it in seven days.

It is recommended that foliar fertilizer can be used at least 2 weeks after the herbicide is used to volatilize the effect of foliar fertilizer, and it is not recommended to apply it too early.

What happens when you hit it.

If you can't fully absorb the nutrients of foliar fertilizer, it will not be enough to maximize the effect of fertilizer, and it will consume foliar fertilizer in vain.

Isn't it okay to have a special herbicide for corn?

Herbicides are all toxic oh kiss, special are gimmicks, and those that can control weeds are toxic <>

Now it's time to apply foliar fertilizer. What can I do to get foliar fertilizer?

Playing potassium dihydrogen phosphate, brassinolide and chlormequat foliar fertilizer is more suitable for corn growth.
