Abstract

The invention provides a special microbial compound fertilizer for vegetables. The microbial compound fertilizer is prepared from the following components in parts by weight: 60-100 parts of a carrier and 15-25 parts of a compound liquid fungicide, and the invention further provides a preparation method thereof. The special microbial compound fertilizer for the vegetables and the preparation method of the special microbial compound fertilizer have the characteristics and advantages that by applying the rhizosphere microbial compound inoculant, the yield of the vegetables can be increased, and meanwhile, the quality of the vegetables can be improved. In addition, by using the product, insoluble phosphorus in soil can be dissolved, nitrogen in air can be fixed, sufficient nutrients can be provided for plants, absorption of other nutrient elements by the plants can be promoted, plant growth can be regulated and promoted, besides, the product can help the plants to resist infection of pathogenic fungi, and the yield can be increased.

Description

technical field [0001] The invention relates to the field of agricultural biotechnology, in particular to a special microbial compound fertilizer for vegetables and a preparation method thereof. Background technique [0002] Vegetables are an important part of agricultural production, an important source of vitamins and minerals for people, and an indispensable food for human beings every day. With the improvement of people's living standards, higher requirements have been put forward for the quality of vegetables, especially their nutrition, hygiene and safety. However, vegetables are generally highly dependent on nitrogen and phosphorus fertilizers. Traditional agriculture mainly relies on chemical fertilizers to provide nutrition for vegetables. In order to pursue higher yields, farmers use chemical fertilizers that seriously exceed the standard. This not only increases purchasing input, but also causes At the same time, it also brings hidden dangers to food safety. For ...
