How to improve Shajiang black soil?

Recently, the reporter received a call from a vegetable farmer in Zaozhuang, Shandong Province. According to him, the climate characteristics of Zaozhuang region are similar to those in Shouguang, and it is reasonable to say that the cultivation conditions of the local greenhouses should be similar to those of Shouguang. However, the same vegetables are grown in both places, but the output is quite different. In addition to factors that have differences in planting technology, the reporter felt that this is also very much related to the local soil conditions.
The vegetable farmer told reporters that the soil in most parts of Zaozhuang is shag black soil. The main characteristics of this soil: First, the texture is more viscous, easy to dry and easy to dry, wet when muddy dry hard, very poor permeability; second, organic matter content is insufficient, only about 1%, but also a serious lack of phosphorus and nitrogen. At present, the area is vigorously developing greenhouse vegetable, and many shortcomings in shajiang black soil seriously restrict the improvement of the economic benefits of greenhouse vegetables. Therefore, how to improve Shajiang black soil has become a topic of great concern to local farmers. After consulting the experts of the newspaper, the reporter summarized the following points for reference by farmers:
(1) In combination with deep turning, organic manure husks are added. After deep-sweeping the soil into the rice manure, first, it can effectively improve the soil structure, increase the permeability of the soil permeability, promote root growth and development, and thus help to cultivate strong trees, increase production. Secondly, the ground temperature can be increased. Due to the viscous weight of shajiang black soil, the soil moisture content is large, and the temperature rises slowly after warming in the spring. After applying rice husk manure, it promotes the activity of microorganisms in the soil, and the microorganisms decompose the organic matter to release heat, thereby effectively increasing the ground temperature. Secondly, organic matter, nitrogen and phosphorus content can be increased. The content of organic matter in organic rice husk manure is about 20%, and it is rich in nitrogen and phosphorus, which can significantly increase soil fertility when applied deep into the soil.
(2) Use a soil conditioner. At this year's Shouguang Vegetable Expo, many types of soil conditioners emerged, among which mineral soil conditioners are more suitable for the improvement of shajiang black soil. The mineral soil conditioner is mainly made of minerals such as medical stone and rare earth. It is a kind of fertilizer applied at the end and can supplement nitrogen, phosphorus, potassium and other elements and boron, zinc and copper that are normally grown and grown in vegetables. Such trace elements can also in-depth conditioning of the soil environment structure, eliminate compaction, effectively increase soil fertility.
(3) After the deep plowing, the soil is mixed with sand or coal ash residue and fertilized rationally. Due to the viscous texture of Shajiang black soil, the water, fertilizer, gas, and heat of the soil are inconsistent. Therefore, where conditions permit, after deep soiling, sand or coal ash residue can be added for improvement, and the power plant can be used to burn off the abandoned coal residue to improve the physical properties of shajiang black soil. has seen an increase.
Reasonable fertilization, it is recommended that organic fertilizer and chemical fertilizer combined application, while the application of trace element fertilizer. Organic fertilizer can increase soil organic matter and promote the formation of granule structure. Shajiang black soil is generally deficient in nitrogen and phosphorus. Rational application of chemical fertilizer can regulate the ratio of nitrogen, phosphorus and potassium in soil and promote crop growth. Boron and zinc in shajiang black soil Lack of trace elements, trace element fertilizer in the bottom application can solve this problem. This method can quickly fertilize the soil and increase the yield of vegetables.
