What are the problems that should be paid attention to in the rational use of pesticides and fertili

In the countryside, there are some old people who farm land, young people have little time in the countryside, and there are very few people who farm the land, and in the process of applying chemical fertilizers, sometimes the old people do not understand, and sometimes some of the handwriting on it may not be understood.

First, the appropriate amount of pesticides and fertilizers. Pesticides are not the more the better, which will not only promote the insects to have self-protection, but also increase the harm to plants, so in the application of chemical fertilizers and the use of pesticides must pay attention to the amount, each time the amount is not too much, not too little, pesticides and fertilizers are too little, some insects are not used at all, so, the degree of use, must be grasped. Sometimes when applying chemical fertilizers and pesticides, the number of days between them is also particular, not too long, and not very close, so as to eliminate all pests and diseases.

Second, the time of spraying. In the past, when we were fertilizing, we were at home, and my parents were always on rainy days.

When I go to the field to sprinkle some fertilizer, in fact, this fertilizer is sprinkled out of trouble, but when the sun shines, in fact, the ingredients are not absorbed by the crops in the field, but absorbed by the sun, so when applying fertilizer, we must pay attention to it, try not to sprinkle it directly in the ground, so that it is easy to save trouble, but many times the crops are not absorbed.

Third, the method of fertilization. , the old man likes to hold a hoe.

Fertilize a seedling pit in the crop field, such a crop field will be well absorbed, but when digging the pit, you must pay attention, do not be too close to the seedlings, if it is too close, it is easy to burn the seedlings.

In fact, when we apply fertilizer, we dig pits and bury fertilizer, and then after all the fertilizer is applied, we are watering the ground, which is very good for the crops, and the absorption is also very good, so the crops have a good harvest.

Fourth, precautions for spraying. When playing pesticides, don't spray pesticides at noon, we know that the sun at that time is very big, and pesticides are absorbed by the sun, which is also versatile.

Whether it is fertilization or pesticide application, there are many important points that need to be learned in practice.

The problem that needs to be paid attention to is the abundance of these drugs, and it is necessary to strictly follow the instructions of the drugs. When spraying pesticides, be sure to pay attention to personal protection. Do not spray pesticides in the scorching sun or on rainy days.

Pay attention to personal cleanliness and hygiene. Pay attention to the interval between medications.

It is necessary to pay attention to the selection of pesticides, do not choose more toxic ones, must be targeted, understand the state of plants, do not use pesticides indiscriminately, and pesticides must be targeted.

The first thing is to choose the right product, to ensure the composition of fertilizers and pesticides, and then it is also necessary to choose the right dosage and the right spraying method according to different crops, and do not mix them.

The common misunderstandings in the application of pesticides and fertilizers in vegetable farmers include the pursuit of quick effect, blind pursuit of new and different, excessive belief in the efficacy of some pesticides and fertilizers, excessive application, unreasonable use methods, unscientific fertilization, and mixed application of a variety of pesticides. Not only can it not achieve the actual effect of application, aggravate the disease, but also continue to cause the production of commercial pesticides to exceed the standard, resulting in soil salinization, etc., the actual I will carry out a specific interpretation below. What are the common problems in the application of pesticides and fertilizers by vegetable farmers?

The pursuit of perfect quick-acting vegetable farmers in the selection and application of chemical fertilizers, has always liked to choose fast-acting, because not long after fertilization can see the actual effect, but this kind of continuous growth is only a steep growth, is very bad for crop growth. The adverse consequences of the pursuit of perfect and quick results, some areas still use toxic, hazardous chemicals, and high residue pesticides, and the pesticide content of the produced products exceeds the standard.

There are all kinds of agricultural and animal husbandry fertilizers on the market, and there are also some pesticides with incomplete certificates and fertilizers produced without licenses. In the case of pesticides, although the use of new pesticides can prevent some pests from developing resistance, many pesticides are now mainly blended agents, and fertilizer damage occurs due to the increase in demand when they are applied. At the same time, some pesticides and fertilizers that have not yet been promoted have little grasp of the actual effect of pesticides and fertilizers, and they are prone to problems.

What are the common problems in the application of pesticides and fertilizers by vegetable farmers?

Excessive belief in the role of some pesticides and fertilizers Many pesticides and fertilizers have application fields in the instructions, so when purchasing, they will choose to indicate that they have many effects, such as pesticides, which can treat bacteria, bacteria, viral infections and other diseases, and will be purchased as good pesticides. In order to better prevent certain types of diseases, some vegetable farmers use too many pesticides or fertilizers, which in turn leads to fertilizer damage or fertilizer damage, causing crops to burn roots, harming production, and also causing soil salinization. The operation method is unreasonable, and the appropriate operation method should be selected at the time of fertilization, so as to achieve the corresponding effect.

For example, in different growth stages of flushing or spraying fertilizer, organic fertilizer is not sufficient erosion, etc., and inappropriate fertilization methods will cause fertilizer damage. What are the common problems in the application of pesticides and fertilizers by vegetable farmers? This is also a problem that will occur to many vegetable farmers, especially when vegetables and fruits lack a certain type of nutrients, and the wrong application of another chemical fertilizer can not only not cure the disease, but may exacerbate the disease.

In the process of fertilization, some vegetable farmers mix several types of pesticide fungicides with trace element fertilizers, insecticides, pathogicides and other types, which not only affects the medicinal power, but also causes fertilizer damage and affects plant growth.

The wrong method of use, not mixing properly, using too much dosage, not binding effect, and not paying attention to the impact on crops, these are all misunderstandings.

These common misunderstandings are that pesticides and fertilizers are not mixed, pesticides are sprayed without protection, pesticides are sprayed when the sun is relatively large, and pesticides are sprayed without paying attention to time and dispersion of pesticides.

Blind pursuit of new brands, excessive belief in certain pesticides or certain chemical fertilizers, excessive fertilization, excessive application of pesticides, failure to use the right method, no right medicine, mixed use of pesticides and fertilizers.

During the planting process, they like to overuse pesticides or fertilizers. The main reason is that the effect is poor. For example, when spraying pesticides, many farmers will double down on their use of pesticides to achieve the desired effect.

They are worried that if the effect is poor after a small dose, they need to fight again, waste labor, and don't want to trouble again. In the case of fertilizers, if a field crop is deficient in nitrogen, phosphorus, potassium or other elements, the symptoms of the crop will be different. In the case of nitrogen deficiency, phosphorus and potassium fertilizer supplementation will not produce a corresponding effect.

In this case, it can lead to damage to the drug or fertilizer. Long-term excessive use of chemical fertilizers can lead to increasingly acidic or hardening of the soil. Long-term overuse of pesticides can lead to increased resistance and reduced control effectiveness.

Whether it's pesticides or fertilizers, it's also a common misconception that using them in the wrong way can not only waste resources, increase costs, but also have no corresponding effect.

In the case of chemical fertilizers, I don't know when to use basal, top and foliar fertilizers, how much to use, and to use organic fertilizers that do not rot. Different crops require different fertilizers, but it is a common misconception that nitrogen, phosphorus, and potassium are used in the same proportion. For example, when pesticides are used, the pesticides are randomly selected and sprayed.

Regardless of when the crop grows, pesticides are sprayed haphazardly, and the time of use of pesticides is relatively arbitrary. In summer, spray insecticides, etc., at high temperatures.

When buying pesticides or fertilizers, they like quick-acting, i.e., fast-acting, because they will be effective very quickly after use. Many farmers believe that after use, the quick-acting things are good, while those pesticides or fertilizers that are slow to act are not good. In practice, we should consider sustainability.

When using fertilizers or pesticides, we all want to be effective throughout the season. While fast-acting pesticides and fertilizers appear to work quickly, they are short-lived and only work for a short period of time. Soon after, they need to be used again.

Those pesticides or fertilizers that act relatively slowly may last longer and work more than the former.

Myth 1: Blindly chasing new and seeking differencesSome vegetable farmers like to use newly launched pesticides and fertilizers. Taking pesticides as an example, although the use of new pesticides can avoid the emergence of resistance to some pests and diseases, many pesticides are currently based on mixtures, and the amount of use will be increased when used, resulting in pesticide damage. At the same time, some pesticide and fertilizer products have not been promoted, and their effects are not well understood, and they are prone to problems.

Misunderstanding 2: Excessive application of many vegetable farmers use pesticides, the amount of organic fertilizer and chemical fertilizer is several times or even more than ten times the applicable amount, often causing pesticide damage and fertilizer damage, which not only increases the production cost, but also seriously affects the quality and yield of vegetables, and the excessive application of one or several chemical fertilizers will also cause soil salinization.

Overuse. Many farmers like to use excessive pesticides or fertilizers in the planting process, the main reason is that they are afraid of bad results, such as spraying pesticides, in order to achieve the desired effect, many farmers will double the use.

Wrong use method: Whether it is pesticide or chemical fertilizer, improper use is also a very common misunderstanding, which will not only waste resources and increase costs, but also has not had the corresponding effect.

Blind pursuit of new products: From the current market, whether it is fertilizer or pesticide, there are many new products every year, many of which are products produced by some "three no" manufacturers.

There are the pursuit of quick effect, blind pursuit of new and different, too much belief in the efficacy of some pesticides and fertilizers, excessive application, improper use of methods, unreasonable fertilization, mixed use of a variety of pesticides, etc.

First of all, we should pay attention to the problem is that when we carry out the relevant mixing, we must pay attention to the proportion of the two, because when the fertilizer and pesticide are mixed together, there must be a certain ratio, if the relevant operation is not carried out according to this ratio, then it is likely to lead to a little more pesticide amount, and if the amount of pesticide is more, it is likely to lead to the most serious consequence after spraying chemical fertilizer, there will be a phenomenon of crop death.

In addition, we also have to pay attention to the relevant types, different fertilizers and different pesticides mixed together, will produce different effects, but we have some fertilizers and pesticides can not be matched together, these must be distinguished, of course, fertilizers and pesticides can not be mixed together, when we buy pesticides, you can ask the people who sell pesticides, generally speaking, like these people are very professional, and for the pesticides they sell are very understanding, Therefore, when you buy pesticides, you must ask which fertilizers can not be mixed with them, if you don't ask clearly, then it is likely to lead to serious consequences.

In the process of spraying pesticides, we should pay attention to a lot of related operational matters, but we will not introduce them here one by one, we spray pesticides and in the process of using pesticides, we should pay attention to a lot of relevant precautions, because pay attention to these things to be able to better protect, we do not recruit Chenghai, but also to protect our health.

There are problems that need to be paid attention to, alkaline pesticides such as Bordeaux liquid, stone sulfur mixture, pine resin mixture, etc. cannot be mixed with ammonium carbonate, ammonium sulfate, ammonium nitrate, ammonium chloride and other ammonium nitrogen fertilizers or superphosphate, otherwise it is easy to produce ammonia volatilization or precipitation, thereby reducing fertilizer efficiency; Alkaline fertilizers such as ammonia, lime, and plant ash cannot be mixed with pesticides such as trichlorfon, dimethoate, sulfacarb, jinggangmycin, carbendazim, etc., because most pesticides will decompose and fail under alkaline conditions. Chemical fertilizers cannot be mixed with microbial pesticides, because chemical fertilizers are volatile and corrosive, and if mixed with microbial pesticides, they are easy to kill microorganisms and reduce the control effect. In the mixed use of fertilizers and pesticides, chemical fertilizers and herbicides are mixed the most, followed by insecticides, and fungicides are less.

Be sure to pay attention when spraying pesticides, and try to spray from top to bottom when spraying, because this will better prevent pesticides from harming the roots of plants.

First of all, we must pay attention to controlling the dosage, and we must choose the right time, the right way to spray, and apply different fertilizers during the seedling period and the growth period, we must pay attention.

Be sure to pay attention to the proportions when mixing. If the proportion is too large, the pesticide is particularly harmful at this time, and it will cause great damage to the crop if sprayed. Then when spraying, the crops must be sprayed, and they must be sprayed evenly, so that the crops will grow particularly vigorously.
