preparation example Construction

[0018] In the present invention, a method for preparing a harmless wheat straw material is provided, wherein the preparation method comprises: first crushing the wheat straw and exposing it to the air for decomposition to obtain cooked wheat straw; Anaerobic treatment is carried out in an oxygen-sealed environment; finally, leguminous plant straw and / or forage plant straw are added for mixing to obtain harmless wheat straw material.

[0019] In the above preparation method, the decomposing conditions used can be selected in a wide range, but in order to further improve the decomposing effect of wheat straw, preferably, the decomposing temperature is 20-25° C. and the time is 60-65 days.

[0020] At the same time, after the wheat straw is decomposed, anaerobic treatment is carried out, and the conditions of the anaerobic treatment used can be selected within a wide range, but in order to further improve the treatment effect on the wheat straw and reduce the toxicity in the wheat...

Embodiment 1

[0029] First, the wheat straw was crushed and exposed to the air, and decomposed at 20°C for 60 days to obtain cooked wheat straw; then, the cooked wheat straw was subjected to anaerobic heating at 70°C for 48 hours in an anaerobic and sealed environment, and after heating and anaerobic treatment Remove the gas generated during the process; finally add soybean, broad bean and pea straw (the length of the straw is 1cm), and the total volume ratio of the added soybean, broad bean and pea straw to the cooked wheat straw is 1:1. The harmless wheat straw material can be obtained after mixing, which is denoted as A1.

Embodiment 2

[0031] Firstly, the wheat straw was crushed and exposed to the air, and decomposed at 23°C for 63 days to obtain cooked wheat straw; then, the cooked wheat straw was subjected to anaerobic heating at 73°C for 60 hours in an anaerobic and sealed environment, and after heating and anaerobic treatment During the process, the gas generated will be removed in time; finally add the stalks of peas, mung beans, cowpeas and peanuts (the length of the straw is 2cm), and the total volume of the straws of peas, mung beans, cowpeas and groundnuts added is 1 to the volume ratio of the cooked wheat straw: 1-1.5 are mixed to obtain the harmless wheat straw material, denoted as A2.

Abstract

The invention discloses a harmless wheat straw material and a preparation method of the harmless straw material. The preparation method comprises the steps of firstly, crushing the wheat straw; then, exposing the wheat straw in air; performing decomposition to obtain rotten wheat straw; next, performing anaerobic treatment on the rotten wheat straw in anaerobic sealing environment; finally, adding leguminous plant straws and / or feed type plant straws for mixing to obtain the harmless wheat straw material. The prepared harmless wheat straw material has no allelopathic inhibition effect on greenhouse vegetables, fruits and other commercial crops; the harmless wheat straw material can be safely used as a fertilization substrate of crops.

Description

technical field [0001] The invention relates to the treatment of plant straws, in particular to a harmless wheat straw, a preparation method thereof, and a fertilization substrate containing the harmless wheat straw. Background technique [0002] At present, three major allelochemicals have been identified in wheat, including phenolic acids, hydroxylamines, and short-chain fatty acids. However, allelochemicals have three effects: promoting effect, inhibiting effect and no significant effect. Among them, the inhibitory effect of allelochemicals will have a certain toxic effect on greenhouse vegetables, fruits and other economic crops. [0003] Due to the diversity of allelochemical substances in wheat, the allelopathic effects also show diversity: not only autotoxic effects, but also allelopathic potentials to higher plants and microorganisms such as other crops, vegetables, and weeds, and chemical effects on pests. Defense becomes an important aspect of allelopathy in whea...
