Special high yield long-acting slow release compound fertilizer for sugarcane planting in dryland

Abstract

The invention relates to the field of crop compound fertilizers and particularly relates to a special high yield long-acting slow release compound fertilizer for sugarcane planting in a dryland. The compound fertilizer is prepared from the following raw materials in parts by weight: 0.5-1 part of copper sulfate, 8-10 parts of calcium magnesium nitrate, 1-3 parts of saccharomycetes, 15-18 parts of winery filter mud, 15-18 parts of rape seed cakes, 5-8 parts of pieces of wood, 2-3 parts of fulvic acid, 8-10 parts of humic acid, 13-14 parts of attapulgite, 3-5 parts of banana skins, 1-2 parts of ammonium polyphosphate, 0.1-0.2 part of pentaerythritol, 8-10 parts of polyvinyl alcohol, 4-5 parts of zinc borate, 6-8 parts of aluminum hydroxide, 3-5 parts of canna leaves, 6-8 parts of eleusine indica, 12-14 parts of old cell mud, 8-9 parts of pseudo-ginseng residues, 1-2 parts of alpha-amylase, 0.2-0.3 part of astaxanthin powder and 3-5 parts of assistants. According to the compound fertilizer provided by the invention, adsorptive powder is prepared from the raw materials such as pieces of wood and pseudo-ginseng residues and is mixed and adsorbed with the raw materials such as organic matter fermentation liquor, astaxanthin and the assistants, and meanwhile, the effect of the slow release fertilizer is realized by an enveloping agent. The compound fertilizer is lasting and efficient in fertilizer release, abundant in content of organic matters and strong in ability of preserving moisture and fertility, and the output and quality of sugarcanes are improved.

Description

technical field [0001] The invention relates to the field of compound fertilizers for crops, in particular to a high-yield and long-acting slow-release compound fertilizer for sugarcane planting in dry land. Background technique [0002] Compound fertilizer plays an extremely important and indispensable role in modern agriculture. Compared with traditional organic fertilizers, it has the advantages of many types of nutrients, high content, high nutrient utilization rate, and convenient packaging, storage, and application. It is the future chemical fertilizer. direction of development. However, most of the existing compound fertilizers have a relatively fixed nutrient ratio, which cannot meet the growth needs of different soil environments and different crop varieties at each growth stage, and eventually lead to the ineffective loss of fertilizer efficiency, and cannot achieve a satisfactory effect of increasing production and income. Therefore, it is very It is necessary to...

However, most of the existing compound fertilizers have a relatively fixed nutrient ratio, which cannot meet the growth needs of different soil environments and different crop varieties at each growth stage, and eventually lead to the ineffective loss of fertilizer efficiency, and cannot achieve a satisfactory effect of increasing production and income. Therefore, it is very It is necessary to formulate special fertilizers for different crops based on the characteristics of fertilizer requ
