Abstract

The invention discloses a crop straw biochar composite microbial organic fertilizer, a preparation method and application thereof. The crop straw biochar composite microbial organic fertilizer is prepared from the following raw materials in percentage by weight: 0.8-1.0% of a composite microbial agent, 0.05-0.15% of arbuscular mycorrhizal fungi, 0.000001-0.00001% of a plant immune resistance inducer, and the balance of crop straw biochar. According to the invention, crop straw biochar, a functional composite microbial agent and a plant resistance inducer are compounded to obtain the crop strawbiochar composite microbial organic fertilizer; and the crop straw biochar composite microbial organic fertilizer can activate a plant immune system and adjust a plant root system ecological system,and has the functions of high fertilizer efficiency and disease and pest prevention.

Description

technical field [0001] The invention relates to the technical field of functional compound microbial fertilizers, in particular to a crop straw biochar compound microbial organic fertilizer and its preparation method and application. Background technique [0002] In recent years, the incidence of various crop diseases has been on the rise, and the risk of epidemic diseases is high, which seriously threatens the safety of food and vegetable production. One of the reasons for the occurrence of the disease is that the production is limited by soil factors, excessive application of chemical fertilizers; the disease of heavy cropping is becoming more and more serious; soil compaction, low organic matter content, unbalanced nutrients, and aggravated secondary salinization. At present, the main measures to break through the limitation of soil factors on agricultural production are to cultivate disease-resistant varieties and increase the application of chemical fertilizers and pest...
