Abstract

The invention provides a special slow release fertilizer for sugarcane. The special slow release fertilizer sequentially comprises a first fertilizer layer, a first film coating layer, a second fertilizer layer, a second film coating layer, a third fertilizer layer and a third film coating layer at a weight part ratio of (4-6) to (1-2) to (6-8) to 1 to (10-12) to (2-3) from inside to outside, wherein the first fertilizer layer is a fermented product of animal manure, marine product leftovers and a microorganism fermenting agent; the first film coating layer is a mixture of bentonite and acrylic resin; the second fertilizer layer is a fermented product of sugar filtering mud, molasses, saw dust, straws, traditional Chinese medicine liquid, yeast waste liquid and a fermentation bacterium agent; the second film coating layer is a mixture of zeolite and attapulgite; the third fertilizer layer is a mixture of a nitrogenous fertilizer, a phosphatic fertilizer, a potash fertilizer and traditional Chinese medicine residues; the third film coating layer is beta-cyclodextrin. The fertilizer is enriched with nitrogen, phosphorus, potassium and microelements; fermentation products and traditional Chinese medicine extracts are added into the fertilizer, and the continuous absorption and utilization on nutrition by the sugarcane are increased so that the releasing time of the fertilizer in soil is prolonged.

Description

technical field [0001] The invention relates to the field of fertilizers, more specifically, the invention relates to a special slow-release fertilizer for sugarcane. Background technique [0002] Sugarcane is an important sugarcane crop in my country. It has a long production cycle and requires a large amount of fertilizer. Fertilization is one of the key technologies for high-yield, high-sugar and efficient cultivation of sugarcane. However, the proportion of nitrogen, phosphorus and potassium in many sugarcane special fertilizers is improper or out of balance, and the content of trace elements such as zinc and boron is also seriously lacking, which seriously affects the growth and development of sugarcane plants. Moreover, in the main sugarcane producing areas in my country, multiple fertilizations are required to meet the nutrients required for sugarcane production. Generally, the entire production period of sugarcane requires the application of basal fertilizer, seedlin...
