A method of using the anaerobic pool seed mud of domestic sewage treatment plant to ferment biomass to produce machine-transplanted rice and seedling-raising substrate method

Abstract

The invention discloses a method of using the anaerobic pond seed mud fermentation biomass production machine of a domestic sewage treatment plant to insert rice and seedling substrates, using crushed rice / wheat straw and rice husk, dehydrated cow dung or chicken manure, or aerobic and Anaerobic treatment of dehydrated domestic sludge is used as the main raw material, and the seed sludge cultivated from the anaerobic bottom sludge of domestic sewage treatment plant is added, and a small amount of low-value attapulgite and uniconazole are added. The main raw materials are mixed according to the C / N of about 25, the water content is adjusted to 60-70%, and the fermentation is stacked for 1-2 months. When the temperature of the pile body exceeds 60°C for 2 consecutive days and needs to be turned over or exceeds 70°C, turn over immediately. After the fermentation is finished, it is sieved, crushed, and packaged into a machine-transplanted rice seedling-raising substrate. The substrate has good water and fertilizer retention properties, appropriate bulk density, good permeability, and good acid-base buffering properties. The seedlings are neat, the seedlings are green, the base is flat, wide and elastic, and there are many white roots. , there is no slow seedling period or very short after transplanting, and can be applied to industrialized intensive seedling raising of machine-transplanted rice.

Description

technical field [0001] The invention belongs to the technical field of machine-transplanted rice seedling raising substrate production technology. It specifically relates to a kind of rice straw, cow dung and other biomass as the main raw material, adding a small amount of low-value attapulgite and a small amount of uniconazole, adding the sludge in the anaerobic tank of the domestic sewage treatment plant as the seed mud, and fermenting to produce the rice seedling raising substrate Methods. Background technique [0002] Since the reform and opening up, with the development of the economy, fewer and fewer people use straw as fuel for cooking in rural areas, and more and more straws are burned in the fields, which not only seriously pollutes the atmosphere, but also affects traffic safety, resulting in series of questions. According to statistics, my country produces 700 million tons of straws annually, but very few straws are utilized as resources, resulting in serious wa...

Problems solved by technology

[0003] The object of the present invention is to solve the problems of waste of biomass resources and environmental pollution such as rice / wheat straw, rice husk, cow dung, chicken manure, domestic sludge, etc. Silt is used as seed mud, and the characteristics of low-value attapulgite, water and fertilizer retention, and bonding properties and the plant dwarf agent uniconazole are used to increase the elasticity of rice seedlings, and a small amount of low-value attapulgite and trace amounts of olefin are added to the raw materials. Meconazole, carry out fermentation and make the method for machine-transplanted rice seedling-raising matrix, the present invention realizes by following technical scheme:
