Eucalyptus seedling culture substrate and production process thereof

Abstract

The invention discloses a eucalyptus seedling culture substrate. The eucalyptus seedling culture substrate comprises the following components in part by weight: 35 to 40 parts of coconut shell powder, 25 to 30 parts of peat, 15 to 20 parts of bentonite, 20 to 25 parts of attapulgite, 0.5 to 0.8 part of soil water-retaining agent, 15 to 20 parts of nutrient substance and 0.2 to 0.3 part of composite strain. A production process of the eucalyptus seedling culture substrate comprises the following steps of: drawing silk from a coconut shell to generate fragments; crushing the fragments; sieving until the granular size is 10 to 20 meshes; performing salt exclusion; mixing 35 to 40 weight parts of the coconut shell powder subjected to the salt exclusion, 15 to 20 weight parts of the nutrient substance and 0.2 to 0.3 weight part of high-temperature-resistant fermenting strain; adding clean water to stir and wet; stacking into a circular truncated cone shape; covering a membrane on the circular truncated cone so as to ferment; and after fermenting completely, adding the peat, the composite strain, the bentonite, the attapulgite and the soil water-retaining agent according to the weight ratio to mix and stir uniformly to prepare into block shapes. The coconut shell powder serves as a main raw material, so the materials are obtained singly and easily, the nutrient ingredients and the content are easy to control, and large-scale standard production can be performed easily.

Description

technical field [0001] The invention relates to seedling raising technology, in particular to a eucalyptus seedling raising substrate and a production process thereof. Background technique [0002] Seedling-raising substrates are used in modern agriculture and forestry to replace soil for seedling-raising. Because seedling-raising substrates are easier to control the nutrient content and realize large-scale production than ordinary soil, they are gradually widely used. [0003] Chinese patent No. 200510061570.2 discloses a "compressed matrix seedling raising nutrition bowl", the composition ratio of which is: peat 35-40, woody nutrients 20-25, livestock manure 15-20, attapulgite 20-25 , Composite strains 0.2 to 0.3. Taking every 100 kg of nutritional bowls produced as an example, 20-25 kg of lignin nutrients with a specification of 30-50 mesh should be mixed with 15-20 kg of livestock and poultry manure, and 0.2-0.3 kg of high-temperature-resistant fermentation bacteria...
