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

A kind of for holding up day Nutrition Soil that tree nutrient cup grows seedlings and preparation method thereof

Technical field

The present invention relates to Forest Tree Nutrient cup seeding raising technology field, be specifically related to a kind ofly for holding up day Nutrition Soil that tree nutrient cup grows seedlings and preparation method thereof, belong to forest seedling growth technical field.

Background technology

Hold up day tree (Parashorea Chinensis Wang Hsie) Dipterocarpaceae Parashorea, megaphanerophyte, high 40-70 rice, diameter of a cross-section of a tree trunk 1.3 meters above the ground 60-160 centimetre, bark grey or brown, trunk top be shallow lobe, straw bag bottom is bulk and peels off, sprout is by lepidiod fine hair, the circular hole skin of tool, leaf keratin, ellipse or ellipticity lanceolar, according to expert investigation examination, only deposit several thousand strains at ground ball clay, be mainly distributed in the ground such as Napo County, Ba Ma county and Daxin County in Yunnan Province of China province Xishuangbanna and southwest, osmanthus, Guangxi Zhuang Autonomous Region.

Hold up that it trees material is hard, durable, rotproofness is strong, be not subject to damage by worms, wood color is isabelline, without special odor, texture is straight, even structure, handling ease, slicing face is smooth, decorative pattern is attractive in appearance, to manufacture various top-grade furnitures, glued board and industrial wood, bridge, building, musical instrument, the quality matetrial of sports apparatus etc., be listed in country-level rare and protected trees, having Important Economic is worth and scientific research value, owing to holding up, it tree existing resource is little, in addition seed longeivity is short, be multiplied into tree by natural germination very difficult, for satisfying the demand, people have to develop artificial cultivation technique, hold up day tree afforestation and carry out, first to solve day sapling wood problem of holding up, low by exposed root and shoot forestation surviving rate, after transplanting, seedling growth is slow.

Assure success to build and hold up a day tree woods, best bet is grown seedlings by nutrient cup exactly, and the Nutrition Soil key link that to be nutrient cup grow seedlings, and growing for seedling growth provides various nutrition and moisture, is the grow seedlings deciding factor of success and failure of nutrient cup.

Summary of the invention

goal of the invention: the object of the invention is the problem for prior art existence, provide a kind of for holding up day Nutrition Soil that tree nutrient cup grows seedlings and preparation method thereof, this Nutrition Soil is according to holding up a day tree growth of seedling feature amount body preparation, guarantee to cultivate and hold up day tree strong sprout, hold up a day tree fast-growing, high-yield woods and provide nursery stock to ensure for building.

technical scheme: Nutrition Soil of growing seedlings for holding up sky tree nutrient cup of the present invention, specifically comprise that yellow earth cubsoil, fire are around turf mud and calcium superphosphate, their component ratio is: yellow earth cubsoil 68%, fiery around turf mud 30%, calcium superphosphate 2%.

The preparation method who the invention also discloses this Nutrition Soil, step is as follows:

1. get yellow earth cubsoil: selecting yellow earth hillside fields, after plane game clock soil layer, get second layer cubsoil, smash carefully, is then square sieve sieve de-stone piece, grass roots and other foreign material of 3～5 ㎜ with sieve aperture;

2, turf mud is burnt in preparation: select near the barren hill of a nursery, first ground weeds shrub is cut down and dries rear concentrated stack up, then with hoe, soil ulmin on the ground, turf, weeds shrub root, epidermal area earth etc. are scraped to heap in the above, with burning to the greatest extent, smashing to pieces, is that the square sieve of 3～5 ㎜ sieves de-stone piece and other foreign material with sieve aperture again;

3, preparation Nutrition Soil: 68% yellow earth cubsoil, 30% fire are mixed and stirred around the calcium superphosphate of turf mud and 2%;

4, Nutritive cube sterilization: the formalin with 0.5% sprays Nutrition Soil, mixes rear accumulation thoroughly, then with plastics film sealing 8～10 days, then remove film, after 2 days, flavour of a drug are evaporated completely just and can use, and pack nutrient cup into.

beneficial effect: the present invention is compared with prior art, its beneficial effect is: it is evenly fine and close that the Nutrition Soil that the present invention produces has quality, preserve moisture and fertility performance is good, transparent performance is good, material weight is light, the not feature of worm and weed seed in spite of illness, can ensure to hold up day required various nutrients and the moisture of tree seedling development.

embodiment

Below in conjunction with the concrete example of implementing, technical solution of the present invention is elaborated.
