Abstract
The invention discloses a method for treating corn straws by earthworm composting. The method comprises the following steps of: smashing the corn straws to obtain the smashed corn straws with the lengths of 0.8-1.2 cm, mixing the smashed straws and rotten chicken manure to obtain a material, wherein the dry weight ratio of the straw powder to the chicken manure is 2.5 to 1, and a ratio of carbon to nitrogen is 35; pre-fermenting the material under the condition of 30 DEG C for 15 days, and then inoculating earthworms, wherein the inoculating proportion is that every 100 g of material is inoculated with three pieces of epifauna type earthworm eisenia fetida and three pieces of endo-anecic type earthworm lumbricus terrestris respectively; composting the materials inoculated with the earthworms at 25 DEG C under the conditions of keeping the water content at 55-65 percent for 60 days to obtain an organic fertilizer. According to the method, the straw composting treatment efficiency can be improved, and the organic fertilizer with high fertilizer efficiency is obtained.
Description
Technical field
The present invention relates to a kind of agricultural biomass method for transformation, particularly a kind of method of utilizing the vermicomposting maize straw.Specifically utilize two kinds of common composting Treating straws of ecotype earthworm, obtain the good fertilizer of fertilizer efficiency.
Background technology
The earthworm multiple organic waste of eating, change it into soil ulmin sample material, i.e. wormcast (Vermicompost).In this process, N, the P, the K that are present in rejected material can be transformed into the form that plant more easily absorbs.Agricultural wastes such as various crop material, due to nontoxic, be rich in a large amount of organic matters, can be used as the good source of earthworm foodstuff.The vermicomposting process is the coefficient decomposition course of earthworm and microorganism.
Earthworm composting thing fertilizer efficiency is good, can Promoting plant growth, improve output.For example, the impact of Arancon et al research earthworm composting thing on strawberry upgrowth situation and output, discovery promotes the strawberry growth after using the earthworm composting thing, output increases, show that leaf area index increases by 37%, the number of flower increases by 40%, and fruit weight can be sold in market increases by 35%, therefore use the earthworm excrement and obviously promote the strawberry growth, improve economic return.The impact of earthworm composting thing on soil physico-chemical property and biological property used in Arancon et al research.Result of study shows, after using the earthworm excrement, soil dehydrogenase activity and microbial biomass N increase, and causes ammonia-state nitrogen and nitrate nitrogen content to increase, and microbe population increases with vigor, promotes soil nutrient to circulate.Produce the hormone of Promoting plant growth and the material of inhibition phytopathogen and nematode in the earthworm composting process.
China's agricultural wastes stable yield and enriching, various agricultural crop straw annual production reach 600,000,000 tons, and the straw utilization mode is comparatively extensive at present, and these stalks are innoxious, recycling treatment, for the development green agriculture with improve the ecological environment very important.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing the vermicomposting stalk, the method is a large amount of agricultural organic wastes of trans-utilization effectively, obtain the good fertilizer of fertilizer efficiency.
Method of the present invention is: with corn straw smashing, the stalk length after pulverizing is 0.8 ~ 1.2cm, and the stalk after pulverizing and the chicken manure that becomes thoroughly decomposed are mixed into material, and the dry weight of straw powder and chicken manure is than being 2.5:1, and make C:N than carbon: the nitrogen ratio is 35; , with this material pre-fermentation 15 days under the 30oC condition, then inoculate earthworm.Inoculative proportion is that every 100g material is inoculated respectively three tables dwell class earthworm Eisenia foetida (Eisenia fetida) and three dark positive earthworms in class earthworm land (Lumbricus terrestris) of dwelling.The material of inoculation after earthworm, at 25oC, kept under water content 55 ~ 65% conditions composting 60 days, obtain fertilizer.
The invention has the beneficial effects as follows: can improve stalk composting processing efficiency, obtain the good organic fertilizer of fertilizer efficiency.
Description of drawings
Fig. 1 is that in vermicomposting maize straw process, C:N compares variation diagram.
Embodiment
With air-dry maize straw, be crushed to 0.8 ~ 1.2cm length, to mix with the chicken manure that becomes thoroughly decomposed, straw powder is with the chicken manure dry weight than being 2.5:1, making the C:N ratio is carbon: the nitrogen ratio is 35., with this material pre-fermentation 15 days under the 30oC condition, then be placed in plastic tank the inoculation earthworm.Inoculative proportion is that every 100g material is inoculated respectively 3 tables dwell class earthworm Eisenia foetida (Eisenia fetida) and 3 dark positive earthworms in class earthworm land (Lumbricus terrestris) of dwelling.Material with after the inoculation earthworm, cover with gauze,, to prevent the earthworm escape, is placed under the 25oC condition, and regularly water spray is kept water content 60% left and right, and composting 60 days, obtain fertilizer.Composting end product nitrogen when composting finishes, phosphorus, potassium content are as shown in table 1, and Mierocrystalline cellulose, hemicellulose and content of lignin are as shown in table 2.C:N during the stalk composting is processed is than changing as shown in Fig. 1.
Table 1 the present invention is on nitrogen, phosphorus, potassium content (mg/kg) and the impact of C:N ratio in maize straw composting end product
Table 2 the present invention is on Mierocrystalline cellulose, hemicellulose and xylogen (%) changing effect impact in maize straw
