Abstract

The invention provides a spruce culture medium prepared from a cassava stalk. The cassava stalk and the spruce skin are respectively smashed into different sizes of particles, after treatment of pile fermentation, the ectomycorrhizal fungi of the spruce is added into the particles and then blended uniformly so as to obtain the spruce culture medium, the spruce culture medium comprises the following raw material components according to parts by weight: 4-5 parts of pile fermenting cassava stalk base material and 5-6 parts of pile fermenting spruce skin base material, the pile fermenting cassava stalk powder base material comprises 100 parts of cassava stalk powder, 100 parts of chicken manure, 0.1 part of cassava powder, 5 parts of superphosphate, 0.05 part of slaked lime powder, and 0.02 part of an enzyme microorganism agent, and the pile fermenting spruce skin powder base material comprises 100 parts of spruce skin powder, 2 parts of urea, 0.02 part of slaked lime powder, and 0.01 part of 95% hymexazol wettable powder. The spruce culture medium makes full use of processing residue of agriculture and forestry, so that the culture of seedling cost is lowered; and the culture medium has the particles with proper size, has a loose structure, is high in organic matter content, contains multiple microelements, is proper in power of hydrogen, has less germ, and is very suitable for growth of spruce seedlings.

Description

Utilize the chinese fir culture matrix of Cassava stalk preparation

Technical field

The invention belongs to field of plant growing technology, relate to a kind of chinese fir culture matrix of utilizing the Cassava stalk preparation.

Background technology

China fir (Cunninghamia lanceolata) growth is rapid, and material is good, and handling ease, purposes are very extensive, are one of important fast-growing commerical tree species in China South China.The existing lanceolata forest area in Guangxi exceedes 1,250,000 hectares, and annual regeneration is more than 500,000 mu, and required afforestation nursery stock quantity is very large.

Cassava is one of south China Main Economic crop, and after the peasant gathered in the crops cassava, outside remaining Cassava stalk depolarization small part gave over to and plants, major part was dropped, or is burnt, and causes the wasting of resources and atmospheric pollution.Cassava stalk contains abundant Mierocrystalline cellulose, hemicellulose, xylogen, protein and mineral element, can be used for cultivating edible mushrooms, simultaneously light, the short texture of Cassava stalk quality, easily decompose, the suction moisture retention is preferably, also the good material of making cultivation matrix, but at present there are no relevant report.

Summary of the invention

The object of the invention is to be dropped or burnt for existing most of Cassava stalk, cause the wasting of resources and atmospheric pollution, be Mierocrystalline cellulose, hemicellulose, xylogen, protein and the mineral element that takes full advantage of Cassava stalk, a kind of chinese fir culture matrix of utilizing the Cassava stalk preparation is provided.

The present invention realizes like this:

A kind of chinese fir culture matrix of utilizing the Cassava stalk preparation, that Cassava stalk and fir hull are ground into respectively the Bu Tong particle of size, after pile fermentation is processed, mix and mix all, obtain chinese fir culture matrix, its raw material forms and parts by weight are: 4～5 parts of stack retting Cassava stalk base-materials, 5～6 parts of stack retting fir hull base-materials; Described stack retting Cassava stalk powder base-material is comprised of Cassava stalk powder 100 weight parts, chicken manure 100 weight parts, Tapioca Starch 0.1～0.2 weight part, calcium superphosphate 5 weight parts, dry hydrate 0.05 weight part, ferment microbial inoculum 0.02 weight part; Described stack retting fir hull powder base-material is disliked mould clever wettable powder 0.01 weight part by fir hull powder 100 weight parts, urea 2 weight parts, dry hydrate 0.02 weight part, 95% and is formed;

Above-described Cassava stalk powder particles is 3～5 orders;

Above-described fir hull powder particles is 8～10 orders;

Above-described ferment microbial inoculum is the commercially available prod.

The preparation method of above-described chinese fir culture matrix comprises the steps:
