Problems solved by technology

However, there are also the following disadvantages: ① this type of conditioning agent is used in a large amount, the cost is high, laborious and laborious, and the powder is not easy to spread
Taking phosphogypsum as an example, the effect can only be achieved when the dosage per hectare is at least 15,000kg; ②The improvement effect is single, and the effect on improving the physical properties of the soil is obvious, but it has little effect on soil fertilization and improving the salt tolerance of crops

Embodiment 1

[0054] The preparation method consists of the following steps:

[0055] 1) Inoculate 2kg of actinomycetes, 2kg of photosynthetic bacteria, 5kg of phosphorus- and potassium-solubilizing bacteria, 3kg of nitrogen-fixing bacteria, 4kg of Bacillus subtilis, and 5kg of plant growth-promoting bacteria into the seed medium respectively to obtain a fermentation seed liquid;

[0056] 2) Inoculate the fermented seed liquid prepared in step 1) into solid-phase medium containing 80 kg of traditional Chinese medicine waste, the inoculum amount is 10%, leave it to ferment at 27° C. in a shallow plate solid-state fermentation device, mix Afterwards, the microbial composite bacterial agent is obtained;

[0057] 3) Mix 50 kg of wolfberry extraction waste, 90 kg of fermented cow dung, 40 kg of desulfurized gypsum, and the microbial composite bacterial agent prepared in step 2) evenly, and carry out fermentation treatment in shading. During the fermentation process, keep the temperature at 35° ...

Embodiment 2

[0059] The preparation method consists of the following steps:

[0060] 1) Inoculate 3kg of actinomycetes, 4kg of photosynthetic bacteria, 2kg of phosphorus- and potassium-solubilizing bacteria, 5kg of nitrogen-fixing bacteria, 2kg of Bacillus subtilis, and 3kg of plant growth-promoting bacteria into the seed medium respectively to obtain a fermented seed liquid;

[0061] 2) Inoculate the fermented seed liquid prepared in step 1) into solid-phase medium containing 50 kg of traditional Chinese medicine waste, the inoculum amount is 12%, leave it to ferment at 25° C. in a shallow plate solid-state fermentation device, mix Afterwards, the microbial composite bacterial agent is obtained;

[0062] 3) Mix 20 kg of wolfberry extraction waste, 45 kg of fermented cow dung, 90 kg of desulfurized gypsum and the microbial composite bacterial agent prepared in step 2), and carry out fermentation treatment in shading, keep the temperature at 15 ° C during the fermentation process, and the ...

example

[0063] Example: A field experiment was carried out in the saline-alkali land of Shizuishan City in the northern part of Ningxia District. 500 kg of microbial soil improvement agent was used as base fertilizer per mu. The soil data before fertilization and the field soil data after fertilization were collected in the test field. The results are as follows:

[0064]

[0065] Table 1: Comparison of soil data in the test field before and after fertilization

[0066] It can be seen from the data in Table 1 that after using the microbial compound soil improvement agent, the alkalinity and salinity of the soil decreased significantly, and the organic matter content and nitrogen, phosphorus and potassium nutrient content in the soil were obvious, and the improvement effect on saline-alkali land was remarkable.

Abstract

The invention relates to a composite microbial soil modifier containing wolfberry fruit extract waste and a preparation method thereof. The composite microbial soil modifier containing wolfberry fruitextract waste is prepared from the following components in part by mass: 5-20 parts of wolfberry fruit extract waste, 15-30 parts of traditional Chinese medicine waste; 15-60 parts of fermented cow dung; 3-30 parts of desulphurization gypsum, and 1-10 parts of microbial composite fungicide. Through the composite microbial soil modifier containing wolfberry fruit extract waste disclosed by the invention and the preparation method thereof, the problems of soil hardening and soil salinizing can be effectively improved, the cost is low, and the effect is obvious; the effect on the physical feature of the improved soil is obvious, and the fertility of the soil and the capacity of improving the salt resistance of the crop are obvious at the same time. By regulating the growth environment in themicrobial flora natural growth multiplicative process, the soil physical property is improved, the mineral nutrients in the soil are activated, the plant nutrient level is improved, and the beneficial microbial amount and the enzyme activity in the soil are improved, the pathogenic microbial activity is inhibited, the disease resistance and the stress resistance of the plant are enhanced, therebyachieving an aim of increasing production and harvesting the crops.

Description

technical field [0001] The invention relates to the field of soil ecological restoration, in particular to a compound microbial soil improver containing wolfberry extraction waste and a preparation method thereof. Background technique [0002] Salinized soil is widely distributed in more than 100 countries and regions around the world, with an area of ​​1.0x10 9 hm 2 , accounting for about 30% of the total land area, distributed in the arid regions of all continents of the world. The proportion of saline soil in China is significantly higher than the world average, with about 1.7x10 saline soil 7 hm 2 , Nearly 1 / 3 of the irrigation areas have soil salinization problems. [0003] Since the 1980s, the extensive use of chemical fertilizers and pesticides in planting has caused soil compaction and increased salinization, posing a serious threat to the agricultural ecological environment. Based on the above reasons, it is proposed to use soil conditioners to improve soil con...
