Problems solved by technology

In 2018, the number of cattle raised in Liaoning Province reached 2.278 million, and the discharge of cow dung is huge and concentrated. If it cannot be treated harmlessly, it will pollute the ecological environment
In traditional agriculture, rice stalks are mostly burned directly or discarded as waste, and most of the rice stalk resources have not been effectively utilized

Embodiment 1

[0042] Decomposed cow dung is mixed with 80% of fresh cow dung and 20% of rice straw according to the volume percentage, and 2kg of microbial compound bacterial agent is added to every 1000kg of fresh cow dung, and it is obtained through 2 times of fermentation and decompression.

[0043]Weigh 4.5g of paclobutrazol, mix it with 9kg of zeolite, add 3.5kg of ammonium sulfate, 2.5kg of superphosphate, 7kg of ferrous sulfate heptahydrate, and 1kg of zinc sulfate, and pour it into a stirring pot for 10 minutes. Take 1L of wood vinegar stock solution and dilute it 40 times, spray it with a sprayer while stirring in a stirring pot, stir for more than 20 minutes and mix thoroughly to prepare 1 part of the preparation.

[0044] Crush and sieve the decomposed cow dung to remove impurities, 1m 3 Add 40kg of zeolite and 1 part of preparation agent to the cooked rotten cow dung, and mix well.

Embodiment 2

[0046] The decomposed cow dung is mixed with 75% of fresh cow dung and 25% of rice straw in volume percentage, and 2kg of microbial compound bacterial agent is added to every 1000kg of fresh cow dung, and it is obtained through 2 times of fermentation and decomposition.

[0047] Weigh 4.5g of paclobutrazol, mix it with 9kg of zeolite, add 3.5kg of ammonium sulfate, 2.5kg of superphosphate, 7kg of ferrous sulfate heptahydrate, and 1kg of zinc sulfate, and pour it into a stirring pot for 10 minutes. Take 1L of wood vinegar stock solution and dilute it 40 times, spray it with a sprayer while stirring in a stirring pot, stir for more than 20 minutes and mix thoroughly to prepare 1 part of the preparation.

[0048] Crush and sieve the decomposed cow dung to remove impurities, 1m 3 Add 40kg of zeolite and 1 part of compounding agent to the decomposed cow dung, and mix well.

Embodiment 3

[0050] The decomposed cow dung is mixed with 70% of fresh cow dung and 30% of rice straw according to the volume percentage, and 2kg of microbial compound bacterial agent is added to every 1000kg of fresh cow dung, and it is obtained through 2 times of fermentation and decompression.

[0051] Weigh 4.5g of paclobutrazol, mix it with 9kg of zeolite, add 3.5kg of ammonium sulfate, 2.5kg of superphosphate, 7kg of ferrous sulfate heptahydrate, and 1kg of zinc sulfate, and pour it into a stirring pot for 10 minutes. Take 1L of wood vinegar stock solution and dilute it 40 times, spray it with a sprayer while stirring in a stirring pot, stir for more than 20 minutes and mix thoroughly to prepare 1 part of the preparation.

[0052] Crush and sieve the decomposed cow dung to remove impurities, 1m 3 Add 40kg of zeolite and 1 part of preparation agent to the cooked rotten cow dung, and mix well.

Abstract

The invention belongs to the technical field of rice mechanized soilless substrate seedling raising, and in particular relates to a rice seedling raising substrate and a preparation method thereof. A soilless seedling raising substrate for rice, the main component of which is decomposed cow dung, 40 kg of zeolite and 1 part of preparation agent are added to each cubic meter of decomposed cow dung, and the mixture is fully mixed and uniform. The seedling-raising substrate can effectively improve the quality of rice seedlings, increase the stem base width of the rice seedlings, increase the above-ground dry weight and underground dry weight of the seedlings, and can effectively inhibit the excessive growth of the rice seedlings. At the same time, the main material of the seedling raising substrate is prepared by mixing and decomposing cow dung and rice straw, which not only realizes the harmless treatment of cow dung, but also realizes the effective utilization of rice straw.

Description

technical field [0001] The invention belongs to the technical field of rice mechanized soilless substrate seedling raising, and in particular relates to a rice seedling raising substrate and a preparation method thereof. Background technique [0002] At present, the mechanized sowing method used in rice production is still based on nutrient soil. The use of nutrient soil as a carrier for cultivating rice seedlings has problems such as large amount of soil taken, difficulty in taking soil, destruction of cultivated land, and susceptibility to soil-borne diseases. In addition, the preparation process of nutrient soil is complicated, labor-intensive, and there are problems such as insufficient nutrients and acidity, which restrict the large-scale development of mechanized rice seedling cultivation. [0003] With the large-scale development of the breeding industry, the harmless treatment of manure has become a major problem. In 2018, the number of cattle raised in Liaoning Pr...
