First, the pursuit of quick-impact. Many vegetable farmers always like to choose quick-acting when they choose fertilizer. The reason is that the effect is obvious soon after use. However, this rapid growth is only a long-term, and it is not good for the whole development process of plants. The serious consequence of the quick-acting effect of vegetable farmers is that the use of highly toxic, high-toxic and high-residue pesticides in some places still exists, and the pesticide residues in the products produced exceed the standard.
The second is to blindly pursue new differences. At present, there are many types of pesticides and fertilizers on the market, and there are some pesticides that are not fully certified and those that are not produced. Taking pesticides as an example, although the use of new pesticides can prevent certain pests from developing resistance, many pesticides are mainly used as a compounding agent, which will increase the amount of use and cause phytotoxicity. At the same time, some pesticide and fertilizer products have not been promoted, and their effects are not well understood, and problems are prone to occur.
The third is to believe too much about the efficacy of certain pesticides and fertilizers. Many pesticides and fertilizers have a scope of application. When purchasing, as long as they are marked, they will be bought and used. If some pesticides indicate that they can cure a variety of diseases such as fungi, bacteria, viruses, etc., they will be purchased as good pesticides.
The fourth is excessive application. Excessive application of pesticides often causes phytotoxicity, and excessive application of chemical fertilizers often causes fertilizer damage, which leads to crop root burning affecting yield. It also causes salinization of the soil.
The fifth is improper use. When applying fertilizer, it is necessary to choose a suitable method of use, such as spraying or spraying fertilizer at different growth stages, and whether the organic fertilizer is sufficiently corroded. If not applied in a proper manner, it will cause damage.
Sixth, it is impossible to prescribe the right medicine and unreasonable fertilization. This is a common problem in the current vegetable production. Especially when vegetables lack certain nutrients, the wrong application of another fertilizer can not only cure the disease, but may aggravate the disease.
Seven is a mixture of a variety of pesticides, many vegetable farmers and several fungicides mixed with micro-fertilizers, insecticides, fungicides and other varieties, not only affect the efficacy, and even produce phytotoxicity, affecting crop growth.
