Embodiment 1

[0022] The preparation method of the nutrient matrix of the present invention's improved saline-alkali land, comprises the steps:

[0023] (1) The organic matter mixture is prepared according to the weight percentage of the following formula: 50% plant fiber, 10% biomass coke, 9% bryophyte, 20% biogas residue, 10% vermicompost, and 1% beneficial microbial flora; among them, the beneficial microbial The flora contains 0.3% of photosynthetic bacteria, 0.39% of Lactobacillus acidophilus, 0.06% of spores, 0.08% of yeast, 0.05% of potassium bacteria, 0.05% of phosphorus bacteria, and 0.07% of actinomycetes;

[0024] (2) Take the organic mixture, add brown sugar water and mix well according to the ratio of 100-150 kg of mixture and 1 kg of 20% brown sugar water;

[0025] (3) Stack retting at 40-50°C for 15-25 days;

[0026] (4) Add vermicompost to the fermented clinker at a ratio of 100:10-15, mix well and serve.

Embodiment 2

[0028] Carry out according to the preparation method of the nutrient matrix of embodiment 1, difference is: according to following formula weight percentage, prepare organic mixture: plant fiber 65%, biomass coke 5%, bryophyte 5%, biogas residue 10%, vermicompost 14%, beneficial microbial flora 1%.

Embodiment 3

[0030] Carry out according to the preparation method of the nutrient matrix of embodiment 1, difference is: prepare organic mixture by following formula weight percentage: plant fiber 58%, biomass coke 8%, bryophyte 7%, biogas residue 14%, vermicompost 12%, beneficial microbial flora 1%.

[0031] The saline-alkali soil nutrient substrate provided by the invention covers 5 to 10 centimeters on the preliminarily improved soil, and after putting 20 live earthworms per square meter, it can be cultivated.

Abstract

The invention discloses a nutrient matrix for improving saline-alkali soil and a preparation method thereof. The method is characterized by comprising the following steps of: preparing an organic substance mixture from 40 to 70 percent of plant fiber, 5 to 10 percent of biomass coke, 5 to 10 percent of moss plant, 10 to 25 percent of biogas residue, 9 to 14 percent of worm excretion and 1 percentof beneficial microbial flora in percentage by weight: adding brown sugar water in a ratio of adding 1 kilogram of 20 percent brown sugar water into 100 to 150 kilograms of mixture, and stirring uniformly; stacking for 15 to 25 days at the temperature of between 40 and 50 DEG C; and adding the worm excretion into the fermented rotten materials in a ratio of 100: (10-15), mixing uniformly, and thus obtaining the nutrient matrix. The nutrient matrix can improve the environment of the saline-alkali soil, and fulfills the purposes of increasing fertility, nourishing soil, holding water and permeating air.

Description

technical field [0001] The invention relates to the improvement of saline-alkali soil, in particular to a nutrient matrix for improving saline-alkali soil and a preparation method thereof. Background technique [0002] The improvement of saline-alkali land is a worldwide problem, and the global saline-alkali land area exceeds 900 million hectares. There are 100 million hectares of saline-alkali land in my country. Saline soil is a part of my country's important land resources, and saline soil occupies a large proportion of wasteland resources. At present, the control technology of saline-alkali soil is mainly to reduce the salt and alkali components through leaching, soil cultivation, and the application of organic fertilizers to increase soil nutrients, and to change the pH value, water retention value, and dissolved air value of the soil through chemical modifiers, effectively reducing The salt in the soil increases soil biological activity, improves soil physical and ch...
