Method for manufacturing compost tea with lawn grass and application of compost tea

Abstract

The invention discloses a method for manufacturing compost tea with lawn grass and application of the compost tea. The method includes steps of 1, collecting fresh plant materials-lawn grass in a current year; 2, adding various components into a closed container according to an EM (effective microorganism) strain-brown sugar-table salt-urea-sterile water proportion of 10:100:3:5:1000 w / w, carrying out anaerobic cultivation at the temperatures of 35 DEG C for 2 d to obtain EM activated bacteria solution; sufficiently drying and smashing the fresh lawn grass, then weighing 1-5 kg of fresh lawn grass, placing each type of materials into a heat-insulation tank, adding 1.5-7.5 kg of activated bacteria solution with EM bacteria into the heat-insulation tank, fermenting each batch of materials for 2 months, then placing thoroughly decomposed materials in plastic buckets with the volumes of 20-100 L, to be more specific, placing 0.5-2.5 kg of raw materials into each bucket, adding 18-45 L of water into each bucket, continuously filling the buckets with air for 3 d, then filtering the raw materials by the aid of filter screens and removing filter residues to obtain liquid which is the compost tea. The method and the application have the advantage that certain crop growth promotion effects can be realized by the compost tea.

Description

technical field [0001] The invention belongs to the field of agricultural technology, in particular, it relates to a method for making turfgrass compost tea and its application. Background technique [0002] At present, the application of chemical fertilizers still occupies a dominant position in my country's agricultural and forestry production process. Due to the lack of scientific fertilization guidance in the farming process, the majority of farmers often mistakenly believe that applying more chemical fertilizers is beneficial to crop growth, resulting in excessive use of chemical fertilizers, which will only increase the cost of planting and harvesting and cause serious waste of chemical fertilizers. And with the impact of continuous cropping obstacles, the phenomenon of eutrophication of cultivated land and irrigated groundwater is becoming more and more serious, and the hidden ecological crisis has become more and more obvious. The formula fertilizer made of compost ...
