Endophyte-containing seaweed composite microbial organic fertilizer for peanuts

Abstract

The invention belongs to the field of agricultural fertilizers, and particularly relates to an endophyte-containing seaweed composite microbial organic fertilizer for peanuts. The organic fertilizer provided by the invention comprises the following raw materials in parts by weight: 400-600 parts of plant-derived organic matters, 300-400 parts of animal-derived organic matters, 100-200 parts of activated humic acid, 40-80 parts of medium trace elements, 10-20 parts of a nutrition regulator, 1-20 parts of a compound microbial agent and 5-10 parts of chitin. The composite microbial fertilizer containing endophytic strains separated from peanut roots instead of other plant endophytes is adopted, so that the fertilizer can be colonized in peanut plants and can survive and grow in the peanut plants, especially in root systems, thereby playing a role in promoting growth; chitin is adopted, the plant autoimmune system can be activated to achieve the disease-resistant effect, no toxicity or harm is caused, and the disease and pest resistance of peanut plants is reduced.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, in particular to a seaweed compound microbial organic fertilizer for peanuts containing endophytes. Background technique [0002] Peanut is one of the important sources of edible oil and protein. At present, the main problems in peanut planting are: 1. Unreasonable use of fertilizers, complex soil types, various varieties of peanuts, and lack of targeted production of peanuts in different regions. Special fertilizer products needed for high-yield and high-efficiency production; 2. Excessive nitrogen application in the early stage inhibits the nitrogen fixation potential of peanuts, and the soil's continuous nitrogen supply capacity for peanuts in the middle and late stages is insufficient, which will easily lead to premature aging, affecting peanut production and planting benefits. [0003] CN108129189A discloses a special urea sulfate microbial fertilizer for peanuts, which is characteriz...

Four kinds of microbial agents have poor control effects on mango powdery mildew

In relieving continuous cropping of peanuts, endophytes have a significant effect. At present, regarding the use of peanut endophytes for compound microbial fertilizers in peanut planting, especially the combination of endophytes and other microbial strains to improve continuous cropping soil There are few publications on microflora and mitigation of peanut continuous cropping obstacles
