Embodiment 1

[0035]Pile 9 tons of wheat straw powder that has been coarsely ground to a height of about 6 meters, and prepare the white rot fungus liquid with a mass concentration of 0.68g / L and Trichoderma reesei Rut-C30 with a mass concentration of 0.39g / L The bacterial liquid is directly sprayed on the raw material pile, and the amount of the sprayed bacterial liquid is controlled at the bottom of the pile until the aqueous solution flows out, and it is maintained for 20 days. Turn the pile as needed, add 90kg of rotund nitrogen-fixing bacteria biological fertilizer, mix well, To obtain a cultivation substrate; in order to further enhance the nutrition of the cultivation substrate, add 1050kg of pig manure, mix well, and mature for 7 days to obtain a high-efficiency cultivation substrate. Apply the cultivation medium evenly on the surface of the saline-alkali land, and the application rate is 2000kg / mu; immediately after the application, perform rotary tillage twice, the depth of rotary ...

Embodiment 2

[0037] Pile 20 tons of elm branch powder that has been coarsely powdered to a height of 5 meters, prepare a mixed solution of 120kg cellulase, 60kg hemicellulase solution, and 50kg lignin peroxidase and spray it directly on the raw material pile, spray The amount of the enzyme mixed solution is controlled at the bottom of the heap until the aqueous solution flows out, and it is maintained for 20 days. Turn the heap as needed, add 90kg of Azotobacter rotundum biological fertilizer, and mix well to obtain a cultivation substrate; in order to further enhance the nutrition of the cultivation substrate , add 1050kg of pig manure, mix well, and mature for 7 days to obtain a high-efficiency cultivation substrate. Apply the cultivation medium evenly on the surface of the saline-alkali land, and the application rate is 2000kg / mu; immediately after the application, perform rotary tillage twice, the depth of rotary tillage is 20cm, and suppress immediately after rotary tillage. Ridge wit...

Embodiment 3

[0039] Pile 9 tons of poplar leaf powder that has been coarsely powdered to a height of about 6 meters, and spray 160kg of laccase into a solution directly on the raw material pile. 1 day, turn the heap as needed, add 6kg of Aspergillus niger XX-15A and 3kg of Candida tropicalis biological fertilizer, and mix well to obtain a cultivation medium; in order to further enhance the nutrition of the cultivation medium, add 9000kg of sheep manure, mix well, and mature After 7 days, a high-efficiency cultivation substrate was obtained. Apply the cultivation medium evenly on the surface of the saline-alkali soil at an application rate of 100kg / mu; perform rotary tillage twice immediately after application, with a depth of 10cm, and suppress immediately after rotary tillage. Ridge with a ridging machine and compact; before transplanting the seedlings, use nitrogen-fixing bacteria fertilizer solution to moisten the seedling roots with soil, and then plant on the ridge according to the de...

Abstract

The invention provides an organic cultivation substrate and a preparation method thereof, and methods for transforming saline alkali land and planting Lycium ruthenicum by using the cultivation substrate. The invention aims to overcome disadvantages in the prior art. According to the invention, fermented agricultural and forest residues, a biological bacterium fertilizer and animal manure are utilized to develop a low-cost and highly-efficient organic cultivation substrate, so the saline alkali land is transformed, and the yield and the quality of the Lycium ruthenicum are improved at the sametime; and an important practical significance is realized for improving the comprehensive development and utilization level of the saline alkali land in China and promoting the sustainable development of agricultural economy in a saline alkali land area.

Description

technical field [0001] The invention relates to an organic cultivation substrate, a preparation method thereof and a method for using the cultivation substrate to transform saline-alkali land and plant black fruit wolfberry. Background technique [0002] Soil salinization is a typical feature of soil in Northwest my country, which seriously restricts the development of agriculture in Northwest China. my country's saline soil accounts for 10% of the country's land area, mainly concentrated in the northwest inland area, and a small part is distributed in the northeast, north China and coastal areas, and has a tendency to gradually expand. Many farmlands have been abandoned due to the impact of salinization, and the salt in these abandoned farmlands quickly accumulates upwards with the evaporation of water, which further aggravates the phenomenon of soil salinization. Most halophytes have strong salt resistance and are good materials for studying plant salt resistance. It is o...
