Is it good morning or afternoon to spray and fertilize vegetables?

Glad for your question!

Whether it is to spray vegetables or fruit trees, field crops, fertilizer, morning or afternoon, it mainly depends on the temperature.

For example, in summer, it is recommended to apply the pesticide after 5 p.m. to avoid high temperatures, and the effect of the pesticide is easier to play. For winter application, it is recommended to apply the pesticide after 10 a.m. to before 3 p.m.

Hope mine, helped!

Fertilizing vegetables should be done in the afternoon; Spraying should be done before 11 a.m. and after 4 p.m.

Hello, land-grown spinach beaten to prevent downy mildew.

The medicine should still be after 4:00 p.m., the sun is not so hot, spinach, easy to absorb. It works well.

Is it good in the morning or good afternoon to fertilize vegetablesGenerally speaking, it should be better in the morning when fertilizing vegetables, because it is easy to absorb in the morning, but if you apply pesticides, it is more appropriate to use pesticides in the afternoon when the sun goes down.

I think it should be better in the evening, the sun goes down in the evening, whether you are spraying medicine or fertilizing, you can let the plant contact time be longer, because after he touches, he can absorb it well throughout the night, because there is no sun at night, it is not easy to evaporate, if you play in the morning, it is easy to evaporate after playing, and it will waste a lot of medicine and waste some fertilizer.

Is it good to spray and fertilize vegetables in the morning or in the afternoon Fertilizing vegetables should use the afternoon time; Spraying should be done before 11 a.m. and after 4 p.m.

It's summer now, and it's best to play in the afternoon when the sun is almost down, because it is easy to dry in the morning, and the effect is a little worse.

Spraying or fertilizing vegetables, morning and afternoon are not particularly suitable, and should be chosen at noon when the sun is more sufficient, because at this time the spraying can maximize the absorption of vegetables, on the one hand, it can kill pests, and the second is more beneficial to the life and development of vegetables, of course, it is not bad to choose the afternoon, but relatively speaking, it is not as good as noon.

Crops can be sprayed in the morning and afternoon。As long as it's not noon. The application time of pesticides is different in different seasons and different growth stages of different crops.

For example, cucumbers in greenhouses are better sprayed on sunny days after 9:00 a.m. and 4:00 p.m. in the hot season because 9:00 a.m

After 00, the dew is dry, the temperature is not too high, and pests and diseases are active, so the spraying effect is best at this time. After 4 p.m., there is frequent activity of pests at night. Spraying pesticides at this time can effectively kill pests.

Generally, on sunny days in summer and autumn, vegetable growers do not spray pesticides at noon. Due to the high temperature in summer, the high temperature at noon is easy to promote the decomposition of the drug, increase the volatilization of water in the liquid medicine, and easily cause drug damage. At the same time, when the weather is hot, the chemical activity of pesticides becomes stronger and the efficacy decreases, but the toxicity of pesticides increases.

Especially when spraying emulsifiable concentrate and various herbicides at high temperatures, it can easily lead to poisoning of pesticide applicators.

In winter and spring, it is generally between 2:30 p.m. and 3:30 p.m

In winter and spring, the temperature in the shed is very low. Spraying at noon will lower the temperature and affect photosynthesis, so spraying in the morning is not appropriate. In addition, in hot weather, crops grow vigorously, the leaves have wide stomata, and phytotoxicity can easily penetrate into the crop, which may cause damage to the crop.

At the same time, high temperatures and the enhancement of the chemical action of the chemical solution may lead to poisoning of the pesticide appliers.

I think it's better to take it in the morning, it may be more conducive to absorption, and it is conducive to the effect of that medicine.

Generally speaking, it is better to spray crops in the morning, because they can be fully affected by sunlight.

I don't think it affects you, as long as the weather doesn't rain.

I don't think it really matters, as long as it's done regularly.

Summary. In winter and spring, it is generally chosen to start spraying after 2 o'clock in the afternoon, especially for greenhouse planting, because the temperature in the shed is low, and it is also the peak period of photosynthesis for crops. In summer and autumn, the spraying of pesticides is generally controlled between 7 a.m. and 10 a.m., or between 4 p.m. and 7 p.m., avoiding the spraying of pesticides at noon high temperatures, the activity of pathogens and pests decreases at noon, and pests are sheltered in the shade.

The reason why spraying pesticides in the morning is that there will be some dew on the plants after waking up in the morning, and after a night of low temperatures, after the sun comes out, the water evaporating from the ground may also condense onto the leaves and become small water droplets. After choosing the time, it depends on the wind of the day, we generally choose to spray crops when the wind is small, so when spraying crops, we should not only look at the season to choose the time of spraying, but also look at the weather conditions of the day, only choose the right time and the right weather.

Just like this spraying time, crop varieties are diverse, cultivation methods are also different, spraying time is also different, on the whole, the more general spraying time: is a sunny day before 10 o'clock in the morning and after 4 pm, to avoid the noon high temperature time, to avoid the morning and evening dew time. In the afternoon, there is no dew at all, and the water on the upper part of the crop has also flowed back to the rhizome, so the pesticide can ensure the adsorption and penetration of the drug, and the effect can be more durable.

Especially at noon on a sunny day, the temperature is the highest of the day, and the volatilization of pesticides is also the largest, which is very bad for the human body. Even in the middle of a cloudy day, I don't recommend doing this. It is important to know that when controlling weeds, insects or diseases, the most suitable activity temperature is generally about 20 30, so that when the temperature and environment are suitable, spraying will have the best control effect, which is more conducive to the daily management of crops.

Abstract Generally, it is better to play at five or six o'clock in the morning, play in the morning, the medicine will evaporate as soon as the sun comes out, and the insects generally do not eat vegetable leaves when the temperature is high in the morning. In order to protect crops, farmers use as few pesticides as possible. Therefore, they should only use pesticides at the right time, in the right place and in the right amount.

What is the best time to spray pesticides on vegetables?

Hello dear. This question is being answered for you, you need to wait patiently for about 5 minutes, and the answer will be revealed for you immediately, please don't worry!

Generally, it is better to play at five or six o'clock in the morning, and in the morning, the medicine will evaporate as soon as the sun comes out, and the insects generally do not eat vegetable leaves when the temperature is high in the morning. In order to protect crops, farmers use as few pesticides as possible. Therefore, they should only use pesticides at the right time, in the right place and in the right amount.

In general, it is recommended to fertilize in the morning in winter, because the temperature is gradually rising, generally reaching a peak between 1200 and 200 at noon, so that the ground temperature will not be lowered and the root system of vegetables will not be damaged, so it is recommended to fertilize in the morning. Vegetables grow faster in the summer and can be fertilized in the morning or at night.

Is it better to fertilize vegetables in the morning or at night.

Is it better to fertilize vegetables in the morning or at night? Each of the experts has different answers. Today, I will carefully analyze for you, how to fertilize vegetables to achieve the best effect?

Vegetable fertilization is mainly determined according to the time period, is it better to fertilize in the morning or at night?

In winter, it is recommended to fertilize in the morning, as the temperature rises gradually, peaking between 12:00 and 2:00 p.m, which will not reduce the ground temperature and will not damage the root system of vegetables, so it is recommended to fertilize in the morning.

Vegetables grow faster in the summer and have higher requirements for fertilizer and water. This time can be applied both in the morning and in the eveningBecause at this time, it is mainly to avoid the high temperature at noon

We generally use drip irrigation to grow vegetables, where fertilizer is drip irrigated directly into the soil. The temperature of fertilization at noon is too high, and it is easy to damage the vegetable root system, so it can be fertilized in the morning and evening.

According to the watering and fertilization process of vegetables planted in small vegetable gardens in recent years, the best time is around 8 o'clock in the morning and after 3 o'clock in the afternoon, so as to avoid watering and fertilizing at noon.

At noon, the sun irradiation intensity is high, the surface temperature is high, if you suddenly pour cold water, the temperature difference is large, and the vegetables can not adapt to the needs of the environment, which is easy to lead to the impact of growth function and reduce the yield of seedlings.

At the same time of watering, dilute the fermented cake fertilizer and water the vegetables at the same time, remember that the fertilizer concentration should be low, so as not to burn the roots and dead seedlings.

There is a proverb among the common people that if you want crops to grow well, water and fertilizer are a treasure. If you want to grow vegetables well, water and fertilizer are the key. Especially in summer, the air evaporates, and the two ends of three days need to be watered and fertilized, and all kinds of vegetables must have a high yield and harvest as long as they do not lack water and fertilizer.

In fact, the time of vegetable fertilization is not so important, mainly the content and amount used in each period are the most critical.

After all, too high fertilizer concentration will cause root burning, and the ratio of nitrogen, phosphorus and potassium used in fertilizer in each growing period of vegetables is different.

In general, in the young fruit stage, it is recommended to use a balanced macro-element water-soluble fertilizer. This can give the vegetables a balanced amount of nutrients, so that the vegetables can grow and bear fruit quickly.

In the middle stage of fruit expansion, a small amount of high-nitrogen, high-potassium water-soluble fertilizer can be used, which can promote rapid fruit expansion.

In the later stage of vegetable growth, high-potassium macro-element water-soluble fertilizer is generally used, which can promote the sweetening and coloring of fruits and increase quality.

I hope you can choose the time, content and amount of fertilization according to the actual situation of vegetable growth.

Summary. When planting crops in greenhouses, fertilizer should be applied first and then sprayed, so that the effect will be better. This is because fertilization can provide the nutrients that plants need, laying a good foundation for the growth and development of crops.

When crops are adequately nutrient, they become more robust and resistant to diseases, better able to tolerate pests and diseases. On the other hand, if the pesticide is applied first and then fertilized, it may have a negative impact on the growth and development of the crop. Doing so will leave chemicals in the soil, resulting in a decrease in soil quality and detrimental to crop growth.

Therefore, in greenhouse planting, it is better to fertilize first and then spray pesticides. Of course, when fertilizing and spraying, it is also necessary to follow the correct method and control the dosage to ensure the healthy growth of the crop.

Greenhouse vegetables, whether to fertilize first in the spray, or spray first in the fertilization which effect is good.

Hello, dear, fertilize first and then spray.

Doing so will leave chemicals in the soil, resulting in a decrease in soil quality and detrimental to crop growth. Therefore, in greenhouse planting, it is better to fertilize first and then spray pesticides.

Of course, when fertilizing and spraying, it is also necessary to follow the correct method and control the dosage to ensure the healthy growth of the crop.

<> Fertilization before planting: well-rotted chicken manure, cow manure, etc. are mixed into the soil as a base fertilizer. Pre-growth fertilization:

Properly apply some compound fertilizer, for leafy vegetables, pay attention to the application of nitrogen fertilizer, promote the growth of branches and leaves, and bury it at a certain distance from the roots. Fertilization in the fruiting period: you can apply rotted human and animal manure, burned plant ash, fermented rice washing water, various residues, etc.

1. What fertilizer to use to grow your own vegetables

1. Fertilize before planting.

Before planting, the soil is prepared and deeply cultivated, and the well-rotted chicken manure and cow manure are mixed into the soil as base fertilizer, which can improve the properties of the soil, improve the fertility of the soil, provide nutrients for the growth of vegetables, and also make vegetables grow well.

2. Fertilization in the early stage of growth.

Vegetables should be fertilized in the early stage of growth, properly apply some compound fertilizer, for leafy vegetables, pay attention to the application of nitrogen fertilizer, promote the growth of branches and leaves, take a small amount of compound fertilizer, buried to a certain distance from the roots.

3. Fertilization during the fruiting period.

Apply some organic fertilizer before flowering and fruiting. In addition to the well-rotted human and animal manure, you can also use burned plant ash, fermented rice water, various residues, etc. When fertilizing, you can dilute it into a solution and irrigate, be careful not to water it on the leaves, or you can dig a pit next to it and bury the fertilizer in it.

2. Do you grow your own vegetables in the morning or at night?

1. In summer, the daytime temperature is high, the sunlight is strong, and the temperature difference between day and night is large. If you choose to apply fertilizer water in the morning, high temperature and scorching sun will increase and accelerate the evaporation of fertilizer water, and the loss of fertilizer and water will be large; In addition, the large amount of evaporation will produce higher temperatures in the soil and the surrounding areas of vegetables, and form a steaming and roasting mode for vegetables, which will cause burns to the roots and aboveground parts of vegetables, and have a very unfavorable impact on the growth of vegetables, and will seriously lead to the death of plants. Therefore, summer fertilization should not be carried out in the morning, and should be carried out in the evening.

2. The temperature in spring and autumn is suitable, the temperature difference between day and night is not large, the evaporation of water in the soil during the day is not large, and early and late fertilization has almost no effect on the normal growth of vegetables.

3. Vegetables can only be eaten a few days after applying compound fertilizer

Vegetables can only be eaten about 10 days after applying compound fertilizer. Compound fertilizer mainly contains nitrogen, phosphorus and potassium and other elements, different varieties, different nutrient content ratios, usually used as a base fertilizer and in the later stage of vegetable growth with water. After the application of compound fertilizer, relatively speaking, the nitrite content in vegetables, especially leafy vegetables, is higher, and the fertilizer effect is released for a certain time, which will be reduced after about 10 days, and the time of harvesting vegetables in the morning should be appropriately late, which can reduce the nitrite content in vegetables.
