Problems solved by technology

[0002] Miscanthus is a perennial C4 tall herbaceous plant of Poaceae. It has the characteristics of low planting cost, strong adaptability, high biomass yield, and strong carbon sequestration capacity. It is considered to be a plant with great potential for development. Its young leaves can be used as Livestock feed, plants have the functions of greening and beautifying, sequestering carbon and improving saline-alkali soil, which can have a good ecological effect on the saline-alkali marginal land in the coastal saline-alkali area of ​​the Yellow River Delta, but how to pollute and recycle miscanthus during the harvest season, Even ecological recycling has never been a feasible solution
[0003] The following problems exist in the recovery and treatment of miscanthus in the coastal saline-alkali land area of ​​the Yellow River Delta: (1) The treatment method in areas where miscanthus has not been recycled is basically incineration
During the process of straw decomposing, it will consume a large amount of available nutrients such as nitrogen in the soil, resulting in a decrease in soil fertility. At the same time, it will also cause soil microorganisms (that is, microorganisms converted from straw) to compete with crop seedlings for nutrients, affecting the growth of seedlings.
(3) There is a certain scale of livestock breeding in the coastal saline-alkali land area of ​​the Yellow River Delta. Livestock manure is naturally fermented and used as organic fertilizer. This method of manure treatment has caused certain pollution

Embodiment 1

[0013] A method for making a compressed culture medium for circular ecological full-nutrition fermentation in coastal saline-alkali land. The production method includes three steps. The first step is to harvest and break Miscanthus and regional agricultural and forestry waste, the second step is to ferment mixed livestock manure, and the third step is to ferment the substrate Compression molding.

Embodiment 2

[0015] The preparation method of the coastal saline-alkali land cycle ecological full-nutrient fermentation compression cultivation medium described in Example 1, the first step is to harvest and break Miscanthus and regional agricultural and forestry wastes, and the climate is cold and dry in autumn and winter in the coastal saline-alkali land area of ​​the Yellow River Delta. At the beginning of December, the Miscanthus stalks and leaves were harvested, mixed with agricultural and forestry wastes and mechanically crushed into fragments and ashes with a length of 3mm-10mm or less.

Embodiment 3

[0017] The production method of the coastal saline-alkali land cycle ecological full-nutrient fermentation compressed cultivation substrate described in Example 1, the second step is to ferment the mixed livestock manure, which is to add 0.1% to 0.5% of the fiber to decompose the crushed straw in the first step Bacteria, 10%~20% livestock manure, 0.5%~1% urea, add water to make the moisture content reach 75%~85%, stir evenly with a mixer, pile up into a pile with a width of 2 meters, a height of 1.5 meters, and an unlimited length Bar stacks, covered with plastic cloth, and fermented; when the temperature in the center of the stack reaches 45°C, turn over the stack, and then cover with film for fermentation, and then turn over when the stack temperature reaches above 60°C; ferment in summer for 10~ 15 days, 30-45 days of fermentation in winter. When the stalks turn brown or dark brown and are soft and elastic when held wet, it indicates that the fertilizer is mature.

Abstract

Povided is a preparing method of a coastal saline circular ecological all-nutrient fermented and compressed culture medium. The preparing method includes the steps of firstly, harvesting and smashingChinese silvergrass and regional agricultural and forestry waste; secondly, fermenting mixed livestock excrements; thirdly, conducting compression-molding on a fermented medium. The preparing method is used for preparing the coastal saline circular ecological all-nutrient fermented and compressed culture medium.

Description

technical field [0001] The invention relates to a preparation method of a cycle ecological full-nutrition fermentation compressed cultivation substrate in coastal saline-alkali land. Background technique [0002] Miscanthus is a perennial C4 tall herbaceous plant of Poaceae. It has the characteristics of low planting cost, strong adaptability, high biomass yield, and strong carbon sequestration capacity. It is considered to be a plant with great potential for development. Its young leaves can be used as Livestock feed, plants have the functions of greening and beautifying, sequestering carbon and improving saline-alkali soil, which can have a good ecological effect on the saline-alkali marginal land in the coastal saline-alkali area of ​​the Yellow River Delta, but how to pollute and recycle miscanthus during the harvest season, Even ecological recycling has never been a feasible solution. [0003] There are the following problems in the recovery and treatment of miscanthus...
