Problems solved by technology

However, at present, modern scientific methods and awareness of straw utilization have not yet been established, and the efficiency of straw utilization is low. A considerable part of straw is incinerated or discarded. It is not uncommon for highways to be closed and planes to fail to land normally due to straw burning every year, resulting in serious waste of resources. and environmental pollution
[0004] At present, there are few reports on soil improvers for facility vegetable fields. Chinese patent CN101531905 (200910071795.4) discloses a secondary salinization conditioner for facility gardening soil and its preparation method, which uses weathered coal or lignite, zeolite and vermiculite to prepare soil Improver prevents secondary salinization of soil; Chinese patent CN101368103 (200710012471.4) discloses a

Embodiment 1

[0029] The present invention takes into account the CO in the facility 2 The soil improver for fertilization, the raw material components are as follows:

[0030] Component A: 50kg each of air-dried corn stalks and wheat stalks;

[0031] Component B: a mixture of 1kg urea and 20kg sterilized chicken manure;

[0032] Component C: 4kg of straw decomposing agent ("Puyuan" brand straw decomposing agent, purchased from Beijing Jingpuyuan Biological Engineering Co., Ltd.) and 4kg of Bacillus subtilis inoculum (trade name: Baicang, purchased from Yunnan Xingyao Biotechnology Co., Ltd. Products Co., Ltd.).

[0033] The present invention takes into account the CO in the facility 2 The preparation method of the soil conditioner for fertilization is as follows: crush corn stalks and wheat stalks to 5-10 cm respectively and mix them, add 1 kg of urea and 20 kg of sterilized chicken manure; The water content is adjusted to 65%, and the plastic film is used for airtight and static stack...

Embodiment 2

[0046] The present invention takes into account the CO in the facility 2 The soil improver for fertilization, the raw material components are as follows:

[0047] Component A: 100kg each of air-dried corn stalks and rice straws;

[0048] Component B: a mixture of 4kg urea and 20kg sterilized chicken manure;

[0049] Component C: 8 kg of straw decomposing agent ("Sanyi" brand straw decomposing agent, purchased from Jining Sanhuan Chemical Co., Ltd.) and 12 kg of Bacillus subtilis agent (trade name: Weiluda preparation, purchased from Zhejiang University Biotechnology Research Place).

[0050] The preparation method of soil improver of the present invention, step is the same as embodiment 1, and difference is: the consumption of each raw material is different, and after the 3rd turn over finishes, turn over 1 time again every 7 days, then turn 2 times continuously After the end of the stacking, that is, 29 days of stacking. Obtain the soil improver for the required facility ...

Abstract

The invention relates to a greenhouse vegetable soil conditioner compatible with CO2 fertilizer application and a preparation method thereof. The greenhouse vegetable soil conditioner of the invention is prepared by grinding an agricultural waste, namely, crop straw serving as a main body, adding a conditioner and a microbial agent according to proportion for static composting and determining an optimal maturity extent by optimizing stack-turning time and stack-turning frequency. Aiming at the degenerative characteristic of the quality of greenhouse vegetable soil, the greenhouse vegetable soil conditioner can remarkably improve the physical and chemical properties of the soil, lower salt content, improve the workability of the soil, prevent and control continuous cropping obstacles of the soil, can remarkably enhance the CO2 concentration in a greenhouse so as to improve the photosynthesis of a crop, remarkably increases crop yield on the basis of improving the sustainable production capacity of the greenhouse vegetable soil and is a greenhouse vegetable soil conditioner compatible with the CO2 fertilizer application; and the soil conditioner has wide raw material source and simple and convenient preparation process and is suitable for large-area popularization and application in China.

Description

technical field [0001] The invention relates to a soil improver for facility vegetable fields and a preparation method thereof, in particular to 2 A soil improver for fertilization and a preparation method thereof belong to the field of agricultural technology. Background technique [0002] Since the mid-1990s, my country's protected vegetable cultivation area has been ranked first in the world, and has reached 2.8 million hm 2 , accounting for more than 80% of the total area of ​​vegetable facilities in the world. my country's facility vegetables use 20% of the vegetable land area, providing 40% of the vegetable output and 60% of the output value. The facility vegetable industry has become the pillar industry of agriculture in many areas of our country. However, farmers’ one-sided pursuit of high yields has been widespread for a long time, and unreasonable input of chemical fertilizers, pesticides and other agrochemicals is very common, resulting in the degradation of soi...
