Nutrient soil for fruit tree seedling production

Abstract

The invention relates to nutrient soil, particularly to nutrient soil for fruit tree seedling production. The nutrient soil is made by soaking sawdust with water, adding ferment bacteria and syrup for sealed fermentation, pouring turfy soil, leaf mold, plant ash, vermiculite powder, bone meal, perlite and composted dung to the fermented sawdust, adding an inorganic fertilizer and performing uniform mixing. The invention provides the nutrient soil for fruit tree seedling production, and the nutrient soil is made by fermenting sawdust and mixing the fermented sawdust with other base materials and fertilizers. The nutrient soil is loose, is relatively rich in potash fertilizer and excellent in drainage performance and air permeability, and has improved the physical behavior, thereby raising the survival rate of seedlings.

Description

technical field [0001] The invention relates to a nutrient soil, in particular to a nutrient soil for raising seedlings of fruit trees. Background technique [0002] At present, the preparation of nutritious soil for fruit tree seedlings is usually done by taking the plow layer soil and adding soil improvement materials such as farmyard manure, pond mud, plant ash, and manure, breaking and mixing with the soil, and then adding fungicides such as thiophanate-methyl and mixing with the soil. The mixed soil can be used as nutrient soil for raising seedlings. The nutrient soil prepared in this way has two obvious shortcomings. One is that the raw materials such as soil, farmyard manure, pond mud, plant ash, and manure usually carry harmful diseases, insects, and weeds that are harmful to crops; During this period, pesticides such as insecticides and fungicides should be frequently used to control the growth of diseases and insect pests. Although this method can also complete...

Problems solved by technology

The nutrient soil prepared in this way has two obvious shortcomings. One is that the raw materials such as soil, farmyard manure, pond mud, plant ash, and manure usually carry harmful diseases, insects, and weeds that are harmful to crops; During this period, pesticides such as insecticides and fungicides should be frequently used to control the breeding of diseases and insect pests

Although this method can also complete the seedling raising process, the whole seedling raising process only superficially controls the breeding and spread of diseases and insect pests, and the source of diseases and insect pests carried in these raw materials has not disappeared. Reproduction and spread, especially sometimes carry some difficult-to-control diseases, and spread to some areas where there is no disease, forming an epidemic, causing devastating damage to crop production

[0003] There are also some technicians who have proposed some other methods for preparing nutrient soil, but these methods are either too complicated to operate, or the raw materials are not easy to obtain, the cost is high, and the practicability is not strong.

At present, there is still a lack of methods for preparing seedling nutrient soil that are accepted and used by the public and can better control the spread of plant diseases and insect pests.
