A special fertilizer mixture for litchi and its preparation method and application

Abstract

The invention discloses a special fertilizer-pesticide mixture for litchi, and a preparation method and application thereof. The special fertilizer-pesticide mixture for litchi comprises the following components in percentage by weight: 0.05-0.2% of disodium octoborate tetrahydrate, 0.01-0.02% of ammonium molybdate, 0-0.02% of zinc sulfate, 0-0.02% of manganese sulfate, 0-0.5% of complexing agent, 0.008-0.01% of prochloraz, 0.128-0.16% of ethanol and the balance of water. According to the invention, the performance of a micro element fertilizer component in the special fertilizer-pesticide mixture for litchi is similar to that of an independent test solution, and is not obviously influenced by pesticide; and the stability of the prochloraz is improved. The special fertilizer-pesticide mixture for litchi is favorable in applicability in case of being sprayed after being mixed, and has favorable applicability in case of mixed storage for less than 3 days while keeping from light and heat. Thus, the special fertilizer-pesticide mixture for litchi can improve the fertilizer-pesticide application efficiency, and save water resources and human resources, namely time cost.

Description

technical field [0001] The invention relates to the fields of pesticides and chemical fertilizers, in particular to a special fertilizer-drug mixture for litchi and its preparation method and application. Background technique [0002] According to statistics, in 2012, the planting area of ​​litchi in my country has exceeded 577,900 hectares, with a total output of 1.552 million tons, ranking first in the world. However, despite the large planting area, litchi planting is still a high-risk industry in nature. In addition to accidental disasters, common downy mildew, anthracnose and insect mite damage are the main reasons for the reduction or even loss of litchi production. In addition, improper fertilization measures may be the source of unstable yield and quality problems. According to reports, due to the strong fixation of boron and other elements in the soil in South China, medium and trace elements are mainly sprayed on leaves, but effective calcium, magnesium, boron an...

Problems solved by technology

[0004] Attributed to medium and micro fertilizers such as Zn 2+ , Ca 2+ The cations are sensitive to alkali. Currently, there are not many fertilizer concentrates on the market that are mainly medium and micro fertilizers, and they are mainly added in small amounts as auxiliary materials; pesticide preparations are mainly mixed water-dispersed particles or monomer emulsions, which can only be dispersed in aqueous solutions. Difficult to organically mix with the aqueous solution of fertilizer

In addition, taking into account the policy factors of the Ministry of Agriculture, the fertilizer-medicine mixed system available on the market is almost only the herbicide-mass fertilizer system, and the medium and micro-fertilizer system has no available finished products and corresponding testing methods and fertilizer efficacy standards
