Ecological rice field compound microbial fertilizer and preparation method thereof

Abstract

The invention provides ecological rice field compound microbial fertilizer and a preparation method thereof and relates to the technical field of fertilizer. The ecological rice field compound microbial fertilizer is prepared from the following components in parts by mass: 5 to 15 parts of humic acid, 10 to 20 parts of bementite, 3 to 7 parts of medical stone, 5 to 15 parts of shell powder, 5 to 15 parts of fishbone dust, 35 to 45 parts of urea, 10 to 20 parts of potassium chloride, 0.5 to 1.5 parts of compound microbial agent and 0.5 to 1.5 parts of chitosan. The ecological rice field compound microbial fertilizer solves the technical problem that rice fertilizer application in a planting, breeding and cocuiture process of an existing ecological rice field has harm to growth and quality of aquatic products, achieves the technical effects of guaranteeing rice nutrient supply balance, achieving good quality and high yield of rice, purifying water quality, guaranteeing normal growth of the aquatic products and constructing a dynamic micro ecosystem of the ecological rice field, further can reduce fertilizer applying times at the same time, prolongs fertilizer action time and reduces economical and labor invest of producers.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a compound microbial fertilizer for ecological paddy fields and a preparation method thereof. Background technique [0002] Ecological paddy field is a new type of paddy field developed based on the principle of symbiosis and mutual benefit between rice and aquatic products. The paddy field area and water area organically combine the planting of green and high-quality rice with aquaculture, which can not only improve the edible quality of rice, but also harvest various aquatic products such as fish, shrimp, crab and shellfish, so as to improve the planting structure and optimize the paddy field ecosystem , to exert the maximum load capacity of rice field resources. [0003] However, in the process of planting and raising ecological rice fields, they always face the problem that fertilization of rice will cause harm to the growth of aquatic products. In order to ensure the n...

Problems solved by technology

[0003] However, in the process of planting and raising ecological rice fields, we always face the problem that fertilization of rice will cause harm to the growth of aquatic products.

In order to ensure the normal growth of rice, it is necessary to fertilize and topdress rice regularly. However, after the existing chemical fertilizers are applied to the rice fields and dissolved, the activity of heavy metals will increase, the pH value will be abnormal, the growth rate of aquatic products will be slow, and even death. At the same time, it will also seriously reduce Quality of aquatic products
