Nutritional soil for nutritious cup nursery of parashorea chinensis and preparation method of nutritional soil

Abstract

The invention discloses nutritional soil for nutritious cup nursery of parashorea chinensis and a preparation method of the nutritional soil, belonging to the technical field of forestry seedling culture and solving the problem of the nutritional soil needed for strong seedling culture of the rare parashorea chinensis. The nutritional soil comprises the following components by weight percent: 68% of yellow subsoil, 30% of fired turf mud and 2% of calcium superphosphate. The preparation method comprises the following concrete steps: taking the yellow subsoil, preparing the fired turf mud, preparing the nutritional soil and disinfecting the nutritional soil. The nutritional soil has the characteristics of dense and uniform texture, good moisture and fertility preserving properties and permeability, light weight and no diseases and pests and weed seeds; various nutrients and moisture needed for growth and development of parashorea chinensis seedlings can be ensured, strong parashorea chinensis seedlings can be cultured, and a nursery stock guarantee is provided for creating fast-growing and high-yield plantation of the parashorea chinensis.

Description

Background technique [0002] Parashorea Chinensis Wang Hsie Dipterocarpaceae, the genus Liuan, a large tree, 40-70 meters high, 60-160 cm in diameter at breast height, gray or brown bark, shallow longitudinal cracks in the upper part of the trunk, and shallow longitudinal cracks in the lower part of the straw bag Massive exfoliation, young branches covered with scaly hairs, round lenticels, leathery leaves, oval or oval-lanceolate, according to expert investigation and evaluation, there are only a few thousand plants in the earth, mainly distributed in Xishuangbanna, Yunnan Province, my country And Napo County, Bama County and Daxin County in the southwestern part of Guangxi...

AI Technical Summary

Problems solved by technology

[0003] Supertree wood is hard, durable, strong in corrosion resistance, and not easy to be eaten by moths; its color is brownish yellow, it has no special smell, straight texture, uniform structure, easy processing, smooth sliced ​​surface, and beautiful patterns. Plywood and high-quality materials for industrial wood, bridges, buildings, musical instruments, sports equipment, etc., are listed as a national first-class rare and protected tree species, which have important economic value and scientific research value. Short, it is very difficult to reproduce trees by natural germination. In order to meet the needs, people have to develop artificial cultivation techniques. To carry out supernatural tree plantation, the problem of supernatural tree seedlings must be solved at first, but the survival rate of afforestation with bare root seedlings is low, and transplantation Seedlings grow slowly after planting
