Organic sustained release pesticide fertilizer specially used for dragon fruits

Abstract

The invention relates to organic sustained release pesticide fertilizer specially used for dragon fruits. The organic sustained release pesticide fertilizer specially used for the dragon fruit contains 12-24 parts of grass ash, 25-30 parts of rape seed cakes, 8-20 parts of cumin, 6-16 parts of xylitol residue, 18-29 parts of humic acid and the like. The organic sustained release pesticide fertilizer specially used for the dragon fruits has the beneficial effects that the organic sustained release pesticide fertilizer has good sustained release performance and long lasting period, and the demand of the dragon fruits in the whole physiological process can be met by only applying the fertilizer once; the organic sustained release pesticide fertilizer has dual functions of preventing and treating plant diseases and insect pests and improving fertility; on one hand, natural pure traditional Chinese herbal medicines are used, occurrence of plant diseases and insect pests of the dragon fruitscan be effectively prevented, usage amount of pesticide and chemical fertilizer is reduced, and production cost is reduced; and on the other hand, the organic sustained release pesticide fertilizer is rich in amino acid nutrient substances, content of vitamin C and amino acids can be increased, and yield and taste quality of the dragon fruits can be increased.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a special organic slow-release medicinal fertilizer for dragon fruit. Background technique [0002] Pesticides and chemical fertilizers play an important role in agricultural production, and the use of a large amount of toxic pesticides and chemical fertilizers not only makes pests resistant to pesticides, but also reduces the utilization rate of chemical fertilizers, resulting in the loss and rapid release of chemical fertilizers, and the continuous accumulation of non-nutrient salts in the soil Or ions, causing soil acidification, compaction, water pollution, crop quality decline, poor taste and flavor. [0003] The slow-release fertilizer mainly adopts the method of "encapsulation", that is, the surface of the fertilizer particles is wrapped with a layer of film to control the release, or a certain fertilizer is used to wrap another fertilizer. This kind of che...

Problems solved by technology

At present, most domestic controlled-release fertilizer coatings are sulfur-coated or polyolefin-coated, of which sulfur-coated controlled-release fertilizers account for the majority, but their nutrient content is low, and the slow-release effect cannot meet the national standard; The release fertilizer is difficult to degrade in the soil due to the very stable structure of polymer materials such as polyethylene and polypropylene.
