A high-efficiency vegetable blend compound fertilizer and its preparation method

Abstract

The invention relates to a high-efficiency vegetable blend compound fertilizer, which includes nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer, and is characterized in that it also includes the following components accounting for the total weight percentage of the compound fertilizer: 2-4‰ chelated boron-zinc fertilizer, 2 ~3% calcium fertilizer, 4~5% magnesium fertilizer and 2~3% potassium polyaspartate. The invention has a scientific proportioning ratio, and mixes boron-zinc fertilizer, calcium fertilizer and magnesium fertilizer in a chelated state with high-nitrogen and high-potassium ternary compound fertilizer and potassium polyaspartate to meet the growth needs of crops, and make vegetables, The quality of melons and fruits is good, the ability to resist diseases and insect pests is strong, and the yield is increased. Moreover, various components are extruded into granules by blending. The quality of potassium aspartate is beneficial to the absorption of crops. It can be seen that this compound fertilizer is an ideal compound fertilizer for economic crops such as vegetables, melons and fruits with comprehensive nutrition, rapid absorption, rooting, and flower and fruit preservation.

Description

technical field [0001] The invention belongs to the technical field of crop compound fertilizer, in particular to a high-efficiency vegetable blend compound fertilizer and a preparation method thereof. Background technique [0002] Vegetables, melons and fruits are inseparable crops in people's daily life, which not only enrich people's diet, but also provide people with beneficial nutrients. The various fertilizers used in traditional planting can no longer meet the needs of the healthy growth of vegetables and melons and fruits. Therefore, through research, people use base fertilizers in the early stage, and then topdressing fertilizers during the growth of crops. The base fertilizer that is more commonly used at present is 15:15 : 15 nitrogen, phosphorus and potassium compound fertilizer, 45% of compound fertilizer or 45% of NK top dressing is commonly used as top dressing, and the use of these top dressings effectively ensures the needs of crop growth. [0003] The comp...

AI Technical Summary

Problems solved by technology

[0003] The composition of traditional compound fertilizers is basically the same. With its large-scale use, the effect of increasing the production of vegetables and fruits continues to decline. It can be seen that there is an urgent need for a compound fertilizer that is conducive to increasing crop growth and improving the ability to resist diseases and insect pests.
