How many pesticides should be applied to an acre of land is the standard?

The number of kilograms of pesticides used per mu should be determined according to the application method. The general water capacity of the manual sprayer is 15 kg, according to the experience, the amount of one acre of land is about 2-3 pots of water, 100 grams of mu means that one acre of water 2-3 pots, with 100 grams of medicine, so the average use of pesticides per mu is 30-50 grams. When using, you can use a small measuring cup to take the medicine and mix it directly with water.

Overview:Not sure, and by no means generalized.

Details:Different growth stages, different varieties of pesticides, and different varieties of plants have different dosages.

1. Differences in dosage at different growth stagesFor the same crop, the amount of pesticides used in the cotton seedling field that has just been transplanted is several times different from that in the cotton field with a large cotton plant in full flowering.

Second, the difference in the dosage of different pesticidesAlthough all are herbicides.

However, when chemical weeding is carried out, chlorofluoropyroxyacetic acid is combined with glyphosate.

The dosage of the drug varies by several times.

Third, the disparity in the dosage of different crop varietiesIt is also used to control the growth of crops, and it is also chlormequatin.

It is used in very small quantities when used in cotton, while it is used in large amounts when used in wheat.

The instructions are very clear, for example, the use of 40% phosphine emulsifiable concentrate to control cabbage insects in vegetable fields, the dosage per hectare is 300-450 grams of liquid medicine, which is converted into 20-30 grams of liquid medicine per mu.

This depends on what kind of medicine you take, and then what kind of plants you grow are standardized?

How many pesticides should be used in an acre of land is the standard. In general, there are instructions on how many grams of water to use for an acre of land, which is regulated.

It depends on the effective dilution factor of the pesticide you play, the normal water consumption is 60 kg per mu, and the multiple of the diluted pesticide is calculated according to the amount of diluted pesticides, which is the standard of how many pesticides should be applied to an acre of field.

There is no standard that says that different crops and different growth stages spray different amounts of medicine. For example: before the crop does not germinate, only 30 catties are needed, when the crop enters the growth period, it is necessary to spray all the crops in an acre of field, which may be several times before germination, so do you understand?

The standard of spraying is to spray all crops, different crops, different phenological periods, different drugs used, and the amount of pesticides used in one acre of land is not a fixed value, that is, there is no standard amount.

It depends on what kind of crops you are growing, what kind of pesticides you want to fight (insecticides, herbicides, fungicides, what insects, bacteria, grasses), what pesticides and so on.

The inappropriate proportion of pesticides is a very painful lesson.

If it is thickened, I am afraid that the crop medicine will die, and if it is diluted, I am afraid that it will not have an effect. How should pesticides be redeemed?

1. How much potion should be sprayed on an acre of land.

First of all, let's be clear:

The sprayer for spraying 1 can is generally 15 kg.

In most cases, it is enough to spray 2 cans on an acre, and if you feel that the pests and diseases are more serious, you can spray more as appropriate, but not more than 3 cans at most.

Second, see the use of drugs clearly, and calculate them against each other.

Then we have to calculate according to the label of the drug.

In order to show you conveniently, we take carbendazim as an example to calculate.

There is not much substance on the front. 50% of this is a proportion that the manufacturer purifies when producing carbendazim to ensure that at least 50% of this wettable powder is carbendazim, which is used to control the quality of drugs.

Let's turn to the back and look at it. What does this mean by multiples, grams, and drug ratios? Don't worry, we'll do it one by one.

1) The dosage of the preparation for fruit trees is 500-1000 times.

This means that if you spray fruit trees, 1 gram of this powder will require 500-1000 grams of water.

We're going to mix a jar of these potions, which is 15 kilograms (15,000 grams).

Approximately the amount of a certain agent (g) = 15,000 (g) dilution factor.

15000 500 = 30 (g) 15000 1000 = 15 (g).

In other words, we need to put 15-30 grams of this carbendazim in a jar.

2) The dosage of the preparation for wheat scab is 100 grams per mu.

This is convenient, two cans per acre, an average of 50 grams per can, just mix with water.

3) 1:100 (drug seed ratio) for cotton seed dressing

This is also easier to calculate, the ratio of medicine seeds is 1:100, that is, 1 kg of medicine can be mixed with 100 kg of cotton seeds. How many catties of seeds do you need to mix, divide by 100 is the amount of medicine you need.

By the way, some of the seed coating agents are written with "coating ratio 1:50" or something like that, referring to the weight of the drug: the weight of water = 1:50.

Pesticides refer to chemical agents used in agriculture to control pests and diseases and regulate plant growth. It is widely used in agriculture, forestry and animal husbandry production, environmental and household health pesticide and epidemic prevention, industrial products mildew and moth prevention, etc. There are many varieties of pesticides, which can be mainly divided into insecticides, acaricides, rodenticides, nematicides, molluscides, fungicides, herbicides, plant growth regulators, etc. According to the raw materials, it can be divided into mineral pesticides (inorganic pesticides), biological pesticides (natural organic matter, microorganisms, antibiotics, etc.) and chemical synthetic pesticides;

Summary. Normal planting of hybrid rice varieties generally requires 2 to 3 catties. The amount of seeds required per mu of rice is generally about 3 catties.

Hybrid rice seeds cost 2 catties per acre of field. If the seedling transplanting mu is planted in catties, if the direct seeding mu is used in 2-3 catties. One acre of rice hybrids kilograms!

Regular species 5 kg! The amount of rice per mu is about 8 catties of japonica rice. Planting one acre of hybrid rice requires about 3 catties of seeds.

One kilogram of rice should be prepared for planting one acre of land.

How many seeds, pesticides, and fertilizers do you need for an acre of paddy field?

How much does rice pest control cost per mu?

Normal Dongliang planting hybrid rice varieties generally requires 2 to 3 catties. The amount of seeds required per mu of rice is generally about 3 catties. Hybrid rice seeds cost 2 catties per acre of field.

If the seedling transplanting mu is planted in catties, if the seed is sown per mu with 2-3 catties. One acre of rice hybrids kilograms! Regular species 5 kg!

The amount of rice per mu is about 8 catties of japonica rice. Planting one acre of hybrid rice requires about 3 catties of seeds. One kilogram of rice should be prepared for planting one acre of land.

How much fertilizer is needed: In the middle and lower reaches of the Yangtze River, Hubei Province, if the land in the plain lake area is more fertile, if it is mainly farmhouse fertilizer, then use 3,000 kg of rotted farmhouse fertilizer, 20 kg of urea, 20 kg of superphosphate, and 10 kg of potassium chloride per mu. If there is no surplus agricultural fertilizer, only Qijia fertilizer is mainly commercial fertilizer, and the land with better soil fertility needs carbon, phosphorus, and potassium fertilizer per mu in total, and the fertilizer consumption of some poorer fields in hilly areas may reach about 100 kg per mu.

The specific amount of fertilizer needs to be flexibly adjusted according to the soil fertility of the planting plot and the rice variety.

Need pesticides: 1. Pesticide to rice depends on the size of the rice seedlings, if the seedlings are cracked, about 20 liters are enough, if the seedlings have grown 30-40 liters of water. 2. In the case of planting seedlings:

Soak one spirit, first purify one. The seedling field is weeded once, and the seedling field is a special herbicide, and the big scatter is sold for about yuan. Seedling field insect removal once or twice, imidacloprid each pack of 2 yuan after transplanting back to green, field weeding once, depending on the grass situation, with benzyl once, with 50-150 grams.

If there is barnyard grass in the field, dichloroquinolic acid can be used once, and if there is sunshine fluttering grass, you can use Qianjin, and if there is water chestnut, you can use dimethyl to tease sodium tetrachloride. Insect treatment depends on the insect situation, generally at least 3 times, each time according to the insect situation with a different drug, in order to delay the pest resistance. 3. In the later stage, Jinggangmycin should be used to prevent and control sheath blight.

Tricyclazole is used to prevent and control ear neck blast. Use a foliar fertilizer to prevent and control premature aging, and seize the last high yield. Do not soak the seeds of the direct seeding field, so save the soaking spirit, use a closed herbicide once after sowing, (Sweep Furte), and the later management and medication are similar to those in the seedling field.

There is no immutable medicine, and it is necessary to adapt measures to local conditions and conditions. As for **, there are also differences from place to place.

In the process of planting rice in rural areas, in order to save trouble, special fertilizers for rice are now used in rural areas. Because the special fertilizer for rice is a fast-acting special fertilizer prepared according to the nutrient components required by rice in the process of growth and development, the balance of nitrogen, phosphorus and potassium ratio, and the supply of medium and trace element fertilizers; In addition, the rice planting area is vast, and the soil nutrient base is not the same in each place and in each rice field, that is, the soil structure is different, the soil fertility is very different, and the nitrogen, phosphorus and potassium three-element fertilizers and medium and trace element fertilizers required are different.

Therefore, the use of rice professional fertilizer, because of the constant nutrient composition, leads to the abundance of some nutrients, resulting in waste, and the lack of nutrients will affect the reduction of rice yield and quality, therefore, the use of rice professional fertilizer will be limited to a great extent, there are great limitations.

Rice special fertilizer, because the nutrients required by rice are relatively complete, the preparation is based on the nutrients required by rice according to the right proportion, the fertilizer composition is very balanced, suitable for the basic fertilizer of rice, is very suitable, but it is necessary to pay attention to the appropriate increase or decrease of the amount of use according to the soil fertility of the rice field. Generally, the special fertilizer for rice is 50 kg per bag, which is suitable for one acre of rice field. If the paddy field is relatively barren, it is necessary to increase 10 20 kg to ensure the supply of fertilizer and increase the yield; If the paddy field is very fertile to avoid overgrowth, lodging and pests and diseases, it is necessary to reduce the amount by 5 20 kg.

These must be based on the actual situation, and cannot be forced to be consistent, otherwise it will violate the planting law and reduce the rice yield.

It is not recommended to use rice-specific fertilizer for rice topdressing. Because the special fertilizer for rice is prepared according to the characteristics of rice growth and development, it is a comprehensive nutrient component, and rice is in the tillering stage at the seedling stage, which is the growth stage of roots, stems and leaves, and requires sufficient nitrogen fertilizer. Sufficient nitrogen fertilizer must be applied at the seedling stage of rice to ensure the rapid growth of rice roots, and provide sufficient nitrogen source fertilizer for plant tillering, which is conducive to cultivating strong seedlings.

Generally, rice is top-applied with 10 30 kg of urea with nitrogen fertilizer during the period of seedling greening, tillering, and growth. The amount of top dressing must be based on the soil fertility and growth and development status of the rice field, and the fertilizer should be applied reasonably, and urea should not be used in excess to avoid causing vigorous growth, which will affect the yield and cause pests and diseases.

If it is foliar silicon fertilizer, spray 1-2 times from the tillering stage to the heading stage of rice, use 1 bottle of foliar silicon fertilizer per mu each time, and spray 1 bottle with 500 ml of water at 1:100.

In general, urea needs 10 kg, potassium chloride needs 10 kg, or you can also use mixed fertilizer, about 30 kg or so.

This is not accurate, because different regions, different soil quality, different cultivation methods, and different varieties will affect the amount of fertilizer used.

Generally speaking, it is not necessary to fertilize it regularly in the middle of 35 40, and then implement it after two or three days, and it must be watered after the fertilizer, so that it can be better absorbed, and the concentration of fertilizer will not harm the crops.

The application time, in our planting process, the diseases encountered are not the same, from the use of pesticides spraying time, the requirements are also different. For example: 1. Some pesticides are required to be sprayed after 9 a.m. and before 11 a.m., and before 3 p.m. and before 7 p.m.

Second, some agents require to be sprayed in the morning, third, there is another agent that needs to be sprayed when with dewdrops, and fourth, sprayed at noon. To sum up: it is rare to encounter pesticide spraying throughout the day.

As for (how many acres of pesticides can be sprayed in a day), it is related to the spraying machinery, such as aircraft spraying pesticides, mobile machinery spraying pesticides, etc., the speed is very fast.

When spraying pesticides with motorized sprayers, there are two types of spraying, lateral spraying, left and right simultaneous spraying, walking speed, etc., relatively speaking, the left and right spraying will improve the efficacy a lot, such as spraying paraquat, depending on their physical fitness or the number of weeds, the height of spraying 5 acres in half a day. Electric sprayers, manual sprayers spray pesticides, and are divided into three-dimensional spraying and obstacle spraying. In general, pesticides can be sprayed in the afternoon half a day, (with a 16-liter sprayer as an example) 8 jugs of water.

Thank you for your question.

Seeds: 50 yuan mu, total 3500 yuan fertilizer: 100 yuan mu, total 7000 yuan labor:

Each mu is calculated as 5 days: 1 day of sowing, 3 days of weeding and soil cultivation, and 1 day of harvesting. 5 days, 70 acres, 60 yuan, days = 21,000 yuan, three items, a total of 31,500 yuan.

The fertilizer, dosage and labor costs are different in different places, and they can be calculated according to the actual situation.

<> herbicides: When the crop is in the 2-4 leaf stage, it can generally be sprayed with 50 grams of drug mixed with 30 kg of water, and when the crop enters the 5-leaf stage, it can generally be sprayed with 50 grams of drug mixed with 50-60 kg of water per mu. Pesticides:

The amount of water mainly depends on the severity of the pest and the pest's resistance, if the pest is more serious and the pest's resistance is higher, then 50-60 catties of water per mu can be mixed (the dosage is used according to the instructions), otherwise it can be mixed with 30 catties of water per mu.
