Problems solved by technology

[0004] In traditional sugarcane planting techniques, the application of fertilizers and insecticides are separated, requiring two to three application of insecticides and fertilizers, which undoubtedly increases the labor intensity and times of labor for farmers
At the same time, sugarcane fertilization management and pesticide application control are not targeted, which easily leads to blind fertilization and pesticide application, resulting in unbalanced fertilization and poor pest control effect
There is no report on the special slow-release granular fertilizer products for sugarcane developed according to the characteristics of sugarcane fertilizer requirements and the occurrence of insect pests

Abstract

The invention provides a sugarcane sustained-release granular medicinal fertilizer comprising the components of, by mass: 0.01-3% of a pesticide, 20-50% of fertilizer effective components, 0.01-2% of trace element fertilizer effective components, 0.001-0.1% of beneficial element fertilizer effective components, 0.1-5% of a fertilizer sustained-release agent, and balance of a filling agent. The fertilizer effective components comprise N, P2O5, and K2O. The trace element fertilizer effective component comprises boron, zinc, manganese, molybdenum, copper and iron. The beneficial element fertilizer effective components comprise silicon and selenium. The sugarcane special-purposed sustained-release granular medicinal fertilizer provided by the invention can provide nutrients for sugarcane, and can control pests effectively. With the medicinal fertilizer, application effects of pesticide and fertilizer are improved, labor intensity is saved, and plantation cost is reduced.

Description

technical field [0001] The invention relates to the fields of pesticides and fertilizers, in particular to sugarcane slow-release granular medicinal fertilizers that integrate nutrition and insecticidal effects. Background technique [0002] Sugarcane is a high-stalk crop with a long growth period and consumes more nutrients than other crops. The imbalance of fertilizer absorption. At the seedling stage, the need for fertilizer is urgent and the amount of fertilizer absorption is small. The demand for nitrogen is relatively large, followed by phosphorus and potassium. In the tillering stage, the amount of fertilizer required gradually increases, and the absorption of the three elements accounts for about 20-30% of the whole period. Entering the elongation period, the absorption of the three elements increases greatly, accounting for more than 50% of the whole period. At this time, it is the season of high temperature, rain and strong sunlight. Sugarcane has the highest util...
