Coated flower fertilizer with bactericidal and insecticidal effects

Abstract

The invention discloses a coated flower fertilizer with the bactericidal and insecticidal effects. The coated fertilizer is prepared from, by weight, 3-4 parts of dioscin, 46-48 parts of guano, 12-14 parts of fresh orange peel, 9-10 parts of leaf mold, 4-5 parts of trisodium phosphate, 7-9 parts of ammonuim humate, 2-3 parts of glucolactone, 1-2 parts of oxidized starch, 39-43 parts of young tangelo fruits, 0.6-0.8 part of dimethylformamide, 1.8-2.0 parts of jasmonic acid methyl ester, 1.1-1.4 parts of polyvinyl alcohol, an appropriate amount of a 50% ethanol solution, an appropriate amount of a 70% methanol solution and an appropriate amount of water. According to the coated fertilizer, the nutrient content is high, the added active components such as dioscin have the good insect expelling effect, and the blended fermented materials of the fresh orange peel, the leaf mold and the like can promote reproduction of an effective microbial community of a root system and prevent proliferation and infection of pathogenic bacteria; meanwhile, the adopted raw materials are all easy to degrade, residual pollutants cannot be caused, the pesticide resistance is not prone to generate, and an ideal usage effect on flower disease prevention and inhibition is achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a flower-coated fertilizer for sterilizing and eliminating insects. Background technique [0002] With the development of specialization, industrialization and scale of planting in our country, its requirements for fertilizers are constantly upgrading, while traditional fertilizers have restricted the sustainable development of planting industry due to their low nutrient utilization. The application of coated fertilizer is an effective way to solve this problem. However, at present, the coating materials of common coated fertilizers are mainly chemically synthesized non-degradable polymers, which are easily left in the soil and cause soil degradation and pollution. At the same time, the coating materials have a single function and usually only have slow and controlled release. The effect does not take into account the functions of water absorption, antibacterial, anti-oxidat...

Problems solved by technology

[0004] The special fertilizer formula for flowers provided by CN101913953B includes photosynthetic bacteria, chitosan, synergist, trace element mixture, nitrogen, phosphorus and potassium inorganic nutrients and natural plant essence, but its nitrogen source, phosphorus source, and potassium source do not have slow-release effects , and are still dominated by large amounts of elements such as nitrogen, phosphorus, and potassium, which cannot well meet the needs of flowers for medium and trace elements, and need to be supplemented separately, which increases the cost of fertilization. adjust accordingly
