A kind of slow-release compound fertilizer for disease-resistant and strong seedlings special for sugarcane planting

Abstract

The invention relates to the field of compound fertilizer for crops, in particular to a slow-release compound fertilizer for disease-resistant and strong seedlings specially used for sugarcane planting. The compound fertilizer is prepared from the following raw materials in parts by weight: urea 30-32, ammonium nitrate 10-12, biogas residue 6 -8, rapeseed cake fertilizer 15-18, bamboo tube 6-8, rice straw 8-10, river sand 15-18, potassium dihydrogen phosphate 28-30, walnut shell 3-5, glucose 5-8, calcium lactate 0.2 -0.3, borax 4-5, copper citrate 0.2-0.3, ferrous citrate 2-4, sodium methyl silicate 0.01-0.02, sodium dodecylbenzenesulfonate 0.2-0.3, sodium dehydroacetate 6- 8. Baking powder 12-15, malt root 4-6, mannoprotein 2-5, β-aminoisobutyric acid 0.01-0.02, polyvinyl alcohol 8-10, loach powder 1-3, additives 3-5; The compound fertilizer of the present invention is made of bamboo tubes, rice grass clippings and other raw materials into absorbent powder, which is mixed with raw materials such as organic fermentation liquid and auxiliary agents to achieve the effect of solid fertilizer, and the effect of slow and controlled release fertilizer is realized by using the coating agent. The compound fertilizer of the invention has long-lasting fertilizer effects, strong seedlings and lush leaves, strong disease resistance, and obvious effects of increasing production and income.

Description

technical field [0001] The invention relates to the field of special compound fertilizers for crops, in particular to a slow-release compound fertilizer for disease-resistant and strong seedlings special for sugarcane planting. 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...

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 requirements of different types of crops, and carry out scientific proportioning. On the basis of not destroying the soil balance, it can prolong the duration of fertilizer effect, improve soil vitality, promote the growth of crop roots, and increase root resistance. Nutrient absorption efficiency, avoiding invalid release of fertilizer effect, so as to achieve the purpose of improving planting efficiency, and realize sustainable green planting, and provide consumers with high-quality products
