Effect Of Biocatalyst On Improving Soil Structure

Soil is the basis of agricultural production,but in the process of industrial development,the corresponding by-products(nitrogen oxides,sulfides,fluorides,heavy metal wastes)are discharged,and chemical agricultural production methods have caused soil pollution to become more and more serious.The degree of soil degradation continues to increase.Due to the slow process of soil formation,restoring the micro-ecology of degraded soil is an effective way to expand the area of agricultural land,increase food production,and improve the soil environment.At this stage,through the efficient use of bioremediation technology,soil pollution can be properly treated,soil structure improvers can be used to improve soil quality,and soil amendments have a wide variety of types,advantages and disadvantages,and the improvement process is not clear,etc.The effect of manure application on the restoration of degraded soil needs to be tested by practice.To this end,in this experiment,ginger was selected as the research object,and two kinds of planting methods of potted plants and ground plants were used to compare the soil physics under three different fertilization treatments:organic fertilizer group,biological bacterial fertilizer group and biological bacterial fertilizer+organic fertilizer group.Properties(soil bulk density,soil porosity),soil pH,soil chemistry(organic matter content,ammonium nitrogen content,available phosphorus content,available potassium content),soil enzyme activity kinetics,soil enzyme activity(catalase)Active,alkaline phosphatase activity,soil urease activity)and ginger quality(chicken yield,ginger plant height,ginger dry matter content,Vc content,soluble glucose content,volatile oil content).The results showed that the effects of three different fertilization methods on soil improvement were biological bacterial fertilizer+organic fertilizer group>biological bacterial fertilizer group>organic fertilizer group.The combination of biological bacterial fertilizer and organic fertilizer could significantly reduce soil bulk density and increase The total porosity of the soil increases the water holding capacity of the soil,so that the soil pH is kept neutral or acidic,which can effectively improve soil fertility,prolong the duration of fertilizer efficiency,and increase the activity of enzymes in the soil.The use of biological bacterial fertilizer+organic fertilizer fertilization method can not only improve the soil,but also improve the quality of ginger.When the ginger is harvested,the total yield is 16.8%higher than that of the control group.The dry matter content,VC content and soluble sugar in the ginger block.The content and volatile oil content were between 5.5% and 11% higher than other treatment groups.As a kind of biocatalyst,biological bacterial fertilizer can directly achieve the optimization of soil structure,improve physical and chemical indicators and biological indicators,and has many remarkable effects such as increasing yield and improving quality.The development and utilization of biocatalysts can not only create conditions for the development of green agriculture,but also have high economic,ecological and social benefits,and is a powerful guarantee for the sustainable development of agriculture.
