Problems solved by technology

In 2007, the number of dairy cows in the country was 12.189 million, and the daily excretion of cow dung was as high as 200,000 to 300,000 tons. Especially in large-scale dairy farms, if there is no effective treatment method, a large amount of cow dung will easily cause serious pollution.
However, there is no report on the preparation of forest tree drought-resistant growth-promoting seedling substrate by comprehensive cattle manure and microbial technology

Embodiment 1

[0053] The substrate was filled with the LKY-1 non-woven fabric seedling forming machine developed for the Shandong Academy of Forestry Sciences. After molding, the matrix is ​​cylindrical, 12 cm high and 9 cm in diameter. Five different experimental treatments were set up, namely, no inoculation of bacterial agent (CK), inoculation of Bacillus subtilis DZ1, Bacillus subtilis GE3, Bacillus cereus Z77, Lactobacillus casei, and the combined bacterial solution of GE3, Z77 and Lactobacillus casei. Among them, Bacillus subtilis DZ1 was preserved on October 14, 2011 in the General Microbiology Center of China Committee for the Collection of Microorganisms, and its preservation number is CGMCC No.5318. Sow after germination. For every treatment of 30 seedling containers, one seedling was fixed in each seedling container on the 15th day after emergence. The seedling height, ground diameter and fresh weight of ash in 15 seedling containers were measured 90 days after sowing. The rem...

Embodiment 2

[0057] The drought-resistant and growth-promoting colloidal matrix of the invention and the conventional container seedling-raising matrix are used to cultivate container seedlings of orientalis arborvitae. The afforestation experiment was arranged in Niuwangquan Beishan, Beimiaoshan Village, Miaoshan Town, Laicheng District, Laiwu City, and the afforestation experiment was arranged on July 12, 2016. The seedlings for afforestation are respectively selected from the drought-resistant growth-promoting colloidal substrate of the present invention and the container seedlings of arborvitae cultivated by conventional container seedling cultivation substrates. The survival rate was surveyed in the year of afforestation, and the survival rate in the next year. The results are as follows: image 3 shown. It can be seen that the survival rate and preservation rate of the seedlings planted with the matrix of the present invention are significantly higher than those of the conventional ...

Abstract

The invention provides a forest drought-resistant growth-promoting colloidal matrix and application thereof. The matrix is formed by well mixing a solid bacterial agent, turf, perlite and vermiculite,the solid bacterial agent is formed by uniformly inoculating drought-resistant microbial combined bacteria liquid into a colloidal fermentation material, and the drought-resistant microbial combinedbacteria liquid is formed by compounding bacillus subtilis GE3, bacillus cereus Z77 and lactobacillus casei 1.0580. Drought-resistant growth-promoting activity of bacillus subtilis GE3 can be given into full play, and coordinated symbiosis effect of bacillus subtilis GE3 among strains can be brought into play; a water-washing cow dung and cow dung biogas residue mixed fermentation product is addedinto the matrix, so that microbial colonization survival performance is further improved, reutilization of waste resources like cow dung is realized, and the matrix has great value in actual application.

Description

technical field [0001] The invention belongs to the technical field of seedling-raising substrates and forestry microorganisms, and in particular relates to a colloidal substrate for forest tree drought resistance and growth promotion and its application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Substrate is an important part of seedling cultivation. It is an artificial soil prepared from organic and inorganic materials and microbial preparations according to the needs of seedling growth. Most of the foreign seedling substrates adopt the formulations of the 1960s and 1970s, such as the composite substrates A and B of Cornell University in the United States. At pre...
