Problems solved by technology

Among all kinds of straw, the annual output of rape straw exceeds 20 million tons, but the comprehensive utilization rate of rape straw is still less than 30%. Its comprehensive utilization is still faced with large output, high cost of returning to the field, and high cost of leaving the field. , Weak technical support, shortage of supporting equipment, difficulties in implementing support policies, and unsound collection and storage systems, etc., and the traditional incineration treatment method will not only cause serious pollution to the environment, but also a huge waste of organic resources
[0005] However, most of the above-mentioned matrix formula components are relatively complicated, the production and processing process is relatively cumbersome, and the quality control of the product is difficult, and most of them still contain traditional matrix materials such as perlite, vermiculite, peat, etc., and the cost is high. In addition, many matrixes also contain Traditional Chinese medicine ingredients, rapeseed cake, bean cake and other components that are prone to deterioration further increase the difficulty of production and transportation, which is not conducive to popularization and application
In addition, many similar substrates are used as cultivation substrates for soilless cultivation, and their formula composition does not meet the needs of the growth and development of vegetable seedlings, so most of them are not suitable for vegetable seedling cultivation substrates
[0006] To sum up, up to now, there are few reports on vegetable-specific seedling-raising substrates made of rapeseed straw as the main raw material.

Embodiment 1

[0048] A kind of rape stalk seedling raising substrate is made of the following raw materials in parts by volume:

[0049] Rape straw 70; river sand 30.

[0050] The preparation method is as follows:

[0051] (1) Rapeseed stalk decomposing treatment: crush the rape stalks into particles with a diameter of 0.1-0.3cm, add 2.0 times the amount of water to it, and simultaneously add a straw decomposing agent equivalent to 0.2% of the total weight of the rape stalks, and the stalks are decomposed The agent is prepared by the ratio of starter: brown sugar: water = 1:1:20. It is activated for 12 hours before use, and the above-mentioned rapeseed straw particles, water and straw decomposing agent are fully mixed to obtain a straw premix, and the straw premix is ​​controlled. The moisture content of the material is 60-65%; the above-mentioned straw premix is ​​stacked up, sealed with a plastic film, turned every 7-10 days, and an equivalent amount of other straw is added to the straw ...

Embodiment 2

[0056] A kind of rape stalk seedling raising substrate is made of the following raw materials in parts by volume:

[0057] Rape straw 65; river sand 28.

[0058] The preparation method is as follows:

[0059] (1) Rapeseed stalk decomposing treatment: crush the rape stalks into particles with a diameter of 0.1-0.3 cm, add 1.8 times of water to it, and simultaneously add a straw decomposing agent equivalent to 0.3% of the total weight of the rape stalks, and the stalks are decomposed The agent is prepared by the ratio of starter: brown sugar: water = 1:1:20. It is activated for 8 hours before use, and the above-mentioned rapeseed straw particles, water and straw decomposing agent are fully mixed to obtain a straw premix, and the straw premix is ​​controlled. The moisture content of the material is 60-65%; the above-mentioned straw premix is ​​stacked up, sealed with a plastic film, turned every 7-10 days, and an equivalent amount of other straw is added to the straw premix befo...

Embodiment 3

[0062] A kind of rape stalk seedling raising substrate is made of the following raw materials in parts by volume:

[0063] Rape straw 75; river sand 32.

[0064] The preparation method is as follows:

[0065] (1) Rapeseed stalk decomposing treatment: crush the rape stalks into particles with a diameter of 0.1-0.3 cm, add 2.0 times the amount of water to it, and simultaneously add a straw decomposing agent equivalent to 0.1% of the total weight of the rape stalks, and the stalks are decomposed The agent is prepared by the ratio of starter: brown sugar: water = 1:1:20. It is activated for 24 hours before use, and the above-mentioned rapeseed straw particles, water and straw decomposing agent are fully mixed to obtain a straw premix, and the straw premix is ​​controlled. The moisture content of the material is 60-65%; the above-mentioned straw premix is ​​stacked up, sealed with a plastic film, turned every 7-10 days, and an equivalent amount of other straw is added to the straw...

Abstract

The invention relates to the field of agricultural planting and vegetable cultivation and especially relates to an oilseed rape straw seedling substrate special for vegetables and a preparation methodthereof. The invention researches an ideal oilseed rape straw seedling substrate by utilizing agricultural wastes--oilseed rape straws as the main raw materials of the vegetable seedling substrate, researching the influences of oilseed rape biological maturity, optimized substrate ratio, physical-chemical parameter regulation and various substrate formulas on the growth and development of the vegetable seedlings and combining with the preparation method and the condition screening. The oilseed rape straw seedling substrate provided by the invention is characterized by simple composition, usesafety, low production cost and simple and feasible processing technology, is beneficial to wide application in the field of vegetable planting and is capable of supplying a novel method for comprehensively utilizing the oilseed rape straw resource.

Description

technical field [0001] The invention relates to the fields of agricultural planting and vegetable cultivation, in particular to a vegetable-specific rape straw seedling-raising substrate and a preparation method thereof. Background technique [0002] As the world's largest agricultural producer, my country's straw production reached about 840 million tons in 2016, accounting for 17.29% of the world's annual straw production, and therefore it has also become the world's largest straw producer. Among all kinds of straw, the annual output of rape straw exceeds 20 million tons, but the comprehensive utilization rate of rape straw is still less than 30%. Its comprehensive utilization is still faced with large output, high cost of returning to the field, and high cost of leaving the field. , Weak technical support, shortage of supporting equipment, difficulties in implementing support policies, and unsound collection and storage systems. The traditional incineration treatment meth...
