Soil conditioner and preparing method thereof

Abstract

The invention discloses a soil microbial habitat improvement agent and a preparation method thereof. The soil improvement agent of the invention is composed of microbial activity factors, gelatin, calcium dodecylbenzenesulfonate, steelmaking slag, and fly ash. The preparation method is: the gelatin of the weight percentage is added into an appropriate amount (3%) of water to dissolve, and the microbial activity factor and calcium dodecylbenzenesulfonate of the weight percentage are added to make the liquid material component A; Steel slag (80 mesh) and fly ash are added to the mixer according to the weight percentage and mixed; add liquid material A, fully stir and serve. Compared with the prior art, the present invention has the functions of improving soil, reducing soil bulk density, improving soil nutrient utilization rate, eliminating soil compaction, balancing soil pH value, increasing soil beneficial microorganism species and activity, promoting crop rooting, absorbing and degrading soil toxin, promoting Advantages of vigorous crop growth.

Description

Technical field [0001] The invention belongs to the technical field of soil improvers, and in particular relates to a soil microbial habitat improver and a preparation method thereof. Background technique [0002] Due to decades of predatory farming in China, nutrients have been lost, and the quality of cultivated land has been severely damaged. Over-reliance on chemical fertilizers has reduced the high-yield performance of crops, and the sustainable output capacity has continued to decline. According to the data analysis of nearly 200 soil nutrient monitoring points in China, the content of organic matter in the soil of cultivated land in China is low, with an average of 1.8%, and most of the dry land is less than 1%, which is 1-3 times different from the soil fertility level of developed countries in Europe and the United States. In the past 10 years, the content of soil organic matter has continued to decline, with a decrease rate of 20%. 70-80% of the cultivated land is...

Problems solved by technology

Due to the high multiple cropping index, farmers are eager for quick success and instant benefits, and it is difficult to popularize

Since the above measures are not effective, the farmers' dependence on chemical fertilizers is further aggravated, so farmers form the concept that in order to obtain high yields, more chemical fertilizers must be applied

In this way, the use of chemical fertilizers has increased year by year, causing soil fertilizer damage to intensify, crop yields have stagnated, quality has declined, farmers' input-output ratios have become smaller and smaller, and they have entered a vicious circle of blind fertilization
