Problems solved by technology

[0003] However, the previous technology used a large amount of chemical pesticides and fertilizers in agriculture, and the long-term application of monotonous fertilizers and pesticides caused great damage to the soil. The pH balance of the soil was out of balance, and harmful minerals were deposited on the soil surface, and the soil was poor in nutrients. , which leads to a great impact on the reproduction of microorganisms beneficial to crop growth, which also leads to crop yield reduction, plant variety variation, etc.
In the past, the use of fertilizers mainly considered the supplement of nutrients needed by plants in different growth stages, such as nitrogen fertilizer, potassium fertilizer, and phosphorus fertilizer. Long-term use of chemical fertilizers and pesticides will have adverse effects on the land and damage the soil properties, thereby reducing yield and crop quality.

Abstract

The invention provides an environment-friendly soil remediation agent as well as a preparation method and application thereof and relates to the technical field of soil remediation. The environment-friendly soil remediation agent is mainly prepared by mixing and fermenting the following raw materials in percentage by weight: 1.5-2.0% of lime, 0.05-0.15% of brown sugar, 20-25% of water, 0.8-3.6% of a composite bacteria solution and the balance of plants. The composite bacteria solution comprises more of bacilli, trichoderma, probiotics and saccharomycetes. The environment-friendly soil remediation agent can remedy the damaged soil and restore the dynamic balance; meanwhile, the cost of the environment-friendly soil remediation agent is also low; the preparation method of the environment-friendly soil remediation agent is simple to operate and convenient to prepare.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to an environment-friendly soil remediation agent and its preparation method and application. Background technique [0002] With the ever-increasing population and the continuous improvement of people's quality of life, the demand for plants, feed and fiber is increasing, and the quality requirements are becoming more and more stringent. In order to improve the quality and output of agricultural products, more efforts are made in agriculture. focus on more efficient production. The growth of plants depends on soil, sunlight and water. The growth of different plants has different requirements for soil, sunlight and water, and the fertility and barrenness of soil play a decisive role in the growth of crops. Therefore, many scientists in the world Soil improvement has done a lot of research and made great progress. [0003] However, the previous technology used a large amoun...
