Preparation method of fertilizer for vegetable plantation

Abstract

The invention discloses a preparation method of a fertilizer for vegetable plantation. The method includes the steps of: 1) using brown sugar to perform enlarged culture on a microbial inoculant to obtain a culture solution, and adding wheat bran into the culture solution to obtain biological wheat bran; 2) mixing and crushing cottonseed hull, coconut shell, bagasse, plant straw, mushroom residue and coal cinder, then adding pig manure, fresh cow dung and a proper amount of water, and stirring the substances; 3) dividing the slurry obtained in step 2) into multiple parts, laying biological wheat bran between every two parts, performing sealing, and conducting fermentation at room temperature; and 4) drying the fermented organic fertilizer, performing crushing, then dividing the product into two parts, making one part of the product, a nitrogen fertilizer and a potassium fertilizer into composite A fertilizer particles, and making the other part and a phosphate fertilizer into composite B fertilizer particles, and taking the compound B fertilizer as the base fertilizer. The green and environment-friendly fertilizer provided by the invention can accelerate the growth of vegetables, also can give full play to the effectiveness of each element, turns waste into treasure, has the functions of water conservation and fertilizer protection, and has the effects of improving the vegetable yield and quality, etc.

Description

technical field [0001] The invention relates to a method for preparing vegetable fertilizer, in particular to a method for preparing fertilizer for vegetable planting. Background technique [0002] The fertilizers used for vegetable fertilizers in my country are mainly nitrogen, phosphorus, and potassium. However, with the development of society and economy, the consumption of vegetables is increasing day by day, and vegetables have gradually become one of the indispensable foods in people's daily diet. The industry can provide people with fresh vegetables every day throughout the year, and has developed rapidly. According to statistics, at present, 15% of the total vegetable supply comes from the greenhouse vegetable planting industry. Excessive application of fertilizers, especially nitrogen fertilizers, leads to problems such as single nutrient, low utilization rate, lack of organic components and medium and trace elements, and the quality and taste of fruits and vegetables...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing fertilizers used for vegetable planting have single nutrient and low utilization rate, which will reduce the quality and taste of fruits and vegetables, and destroy the soil structure, causing huge damage to the ecological environment. The fertilizer preparation method for planting can accelerate the growth of vegetables and give full play to the effectiveness of each element. At the same time, trace elements and plant hormones required for plant growth are added to the fertilizer to improve the yield and quality of greenhouse vegetables and meet the needs of crops. Needs for the growth of branches, stems and leaves, fruits and grains, and turning waste into treasure, is friendly to the environment, slowly releases fertility, has the functions of water retention, fertilizer retention, and improves the yield and quality of vegetables, etc.
