Nutrient soil for growing seedlings of guangxi green plum in nutrient cup and preparation method of nutrient soil

Abstract

The invention discloses nutrient soil for growing seedlings of guangxi green plum in a nutrient cup. The nutrient soil comprises 57% of yellow earth subsoil, 30% of burned turf sludge, 10% of honeycomb coal ash and 3% of phosphatic fertilizer. The invention also discloses a preparation method for the nutrient soil. The preparation method comprises the following specific steps: preparing the yellow earth subsoil, preparing the burned turf sludge, preparing the nutrient soil and sterilizing the nutrient soil. The nutrient soil belongs to the field of seedling raising technology. The problem of the nutrient soil for growing a strong seedling of the precious guangxi green plum is solved. The nutrient soil has the characteristics of being compact and uniform, good in water and fertilizer retention, good in permeation, and having no diseases and pests and weed seeds, and can be used for providing various nutrients and moisture for growing of guangxi green plum seedlings, guaranteeing that the seedlings of the guangxi green plum are strong, and providing good seedlings for creating a fast-growing and high-yield plantation of guangxi green plum.

Description

technical field [0001] The invention relates to the technical field of tree nutrition cup seedling cultivation, in particular to a nutrient soil used for Guangxi green plum nutrition cup seedling cultivation and a preparation method thereof, belonging to the forest tree seedling cultivation technical field. Background technique [0002] Guangxi Qingmei (scientific name: Vatica guangxiensis) is a species of Dipterocarpaceae, about 30 meters high, with annual branches densely covered with yellowish-brown to brown star-shaped hairs, old branches glabrous, leathery leaves, oval Oval-shaped and lanceolate, it likes warm winters, not hot summers, and high humidity all year round. It was originally distributed in Guangxi (Napo), where it grows on slopes and hills. [0003] Guangxi Qingmei is a typical tropical tree species newly discovered in China. It has a straight and round trunk, fine wood structure, strong material, corrosion resistance, smooth and smooth after planing. It is ...

Problems solved by technology

[0004] Due to the lack of existing resources of green plums in Guangxi and the short lifespan of seeds, it is very difficult to grow trees by natural germination. In order to meet the needs, people have to develop artificial cultivation techniques. To carry out artificial afforestation of green plums in Guangxi, the problem of Guangxi green plum seedlings must first be solved. However, the use of bare-root seedlings to grow Guangxi greengage is very demanding on the land and climate, the survival rate of afforestation is low, and the seedlings grow slowly after transplanting
