Technical Field

The invention belongs to the technical field of pesticides and fertilizers, and particularly relates to a double-machine double-control marine biological peptide multifunctional pesticide fertilizer and a preparation method and application thereof.

Background

In the traditional agricultural production, the fertilizer application and the pesticide application of crops are carried out separately, so that the labor intensity of farmers is increased, the labor times of the farmers are increased, and time and labor are wasted. The pesticide and the fertilizer are mixed or combined for use in agricultural production, so that the two field operation steps are combined into one, the pesticide and the fertilizer are integrated, the time, the labor and the resources can be saved, the production cost is reduced, the antagonism between the pesticide and the fertilizer and the adverse effect on crops are avoided, the synergistic effect between the pesticide and the fertilizer is increased, the using amount of the pesticide and the fertilizer is reduced, the optimal application effect is obtained, and the purposes of protecting the environment and improving the crop yield are achieved.

The pesticide fertilizer is a novel ecological compound fertilizer formed by mixing pesticide and fertilizer according to a certain proportion and stabilizing the fertilizer and the pesticide in a specific compound system through a certain process technology. The agricultural chemical integrates the two most important agricultural chemicals of the pesticide and the fertilizer used in agricultural production, fully considers the influence that the respective effects of the pesticide and the fertilizer are decreased gradually after the pesticide and the fertilizer meet naturally, and combines the two field operations of plant protection of the pesticide and nutrient supply of the fertilizer into a whole, thereby achieving the purposes of saving labor and reducing production cost.

Although a plurality of medicine and fertilizer integrated products are circulated in the market at present, the medicine and fertilizer integrated products have some defects, so that the whole effect of the medicine and fertilizer product is not ideal, and the purposes of light weight, simplicity, labor saving and cost saving are not really achieved, and the medicine and fertilizer integrated products are mainly expressed as follows: (1) most of the pesticide fertilizer products pay more attention to pesticide effect, and neglect fertilizer effect, the pesticide fertilizer can be used as a single nutrient of the fertilizer, has no balanced formula, has poor fertilizer effect, causes no follow-up of crop nutrition, and has no good pesticide effect and fertilizer effect; (2) the release speed of pesticide is controlled by singly considering most pesticide fertilizer products, and double controlled release of the fertilizer and the pesticide is not considered at the same time, so that the fertilizer effect period is short, the late-stage fertilizer release of crops is serious, and the effect is not ideal; (3) most of pesticide fertilizer products are simple or unreasonable in production process, only pesticides and fertilizers are simply mixed, but the simple mixing of the pesticides and the fertilizers is very unstable and easy to react, so that the effect of the product is affected; (4) the pesticide fertilizer product has single function, most of the pesticide fertilizer only provides a large amount of nitrogen, phosphorus and potassium fertilizers for crops and has the functions of killing insects or preventing diseases, and other functional fertilizers (trace, beneficial element fertilizers or biological stimulants and the like) are required to be additionally applied to meet the growth requirements of the crops; (5) most of pesticide fertilizer products are chemical pesticides and chemical fertilizers, and the phenomena of soil acidification, soil hardening and soil nutrient imbalance are easily caused after long-term use, so that the quality of crops is reduced.

Therefore, there is a need to develop a multifunctional pesticide fertilizer which has both excellent pesticide effect and fertilizer efficiency and realizes dual controlled release of fertilizer and pesticide.
