Talking about the Causes of Vegetable Continuous Cropping Obstacle and Soil Remediation Technology
Vegetable continuous cropping barriers can cause soil productivity to decline. This phenomenon is more common in agricultural production. How can we prevent this from happening? Let's take a look at the causes of vegetable continuous cropping obstacles and soil remediation techniques. First, the basic principles in the process of soil protection In the process of soil environmental protection and improvement, certain land use rules must be followed, so that the value of the soil can be fully utilized. In the process of land protection, organic fertilizer and inorganic fertilizer must be used together. In the process of fertilization, it is best to use organic Fertilizer-based; in the process of using fertilizer, the primary and secondary of the two must be distinguished. The fertilization must be carried out on a yearly basis according to the actual conditions of the soil, so as to continuously improve the fertility of the soil; in the process of fertilization and soil improvement, it must be based on local actual conditions. The situation is analyzed, for example, the viscosity of the soil in the protected area is required to be fertilized with a fertilizer containing a higher crude fiber, so that the soil improvement effect is more obvious, and the loss of fertility can be effectively avoided. Second, the reasons for the emergence of vegetable continuous cropping obstacles 2.1 Secondary salinization and acidification of soil In the process of vegetable planting, because the vegetable farmers neglect the scientific use of fertilizers, the secondary salt and acidification of the soil is caused. For example, in the process of planting, the vegetable farmers use excessive amount in each season of fertilization in order to obtain greater economic benefits. High concentration of chemical fertilizers. The use of this cycle, vegetable film covering process, long fermentation of high temperatures, under natural conditions in the soil surface aggregates salt after evaporation of soil fertilizer, causing secondary salinization. 2.2 The accumulation of harmful substances In the process of vegetable planting bacteria, fungi, actinomycetes is the most important microorganisms, actinomycetes produce antibiotics have a fundamental effect, which has an important impact on agricultural production, but at this stage of the process of agricultural production, is mostly covered film, in the long term to cover the environment, a direct result of bacteria, fungi multiply rapidly, resulting in decline in the number of actinomycetes, while the decline in the number of actinomycetes direct result of the rapid spread of soil pests and diseases, which cause soil of harmful substances is increasing, It poses a great threat to agricultural production. 2.3 Plant self-toxicity The self-toxicity mainly refers to the toxic state secreted by the roots of plants in the agricultural production process. These substances mainly inhibit the decomposition of related enzymes of crops, and the autotoxicity also inhibits the photosynthesis of crops, thereby inhibiting the growth of crops. For example, tomatoes, eggplants, watermelons, etc., such as watermelons are continuously planted in the same plot. In the second year, the roots of watermelons are long-term nematodes, causing watermelon seedlings to die. Therefore, necessary measures must be taken during the current vegetable growing process to promote the steady development of the agricultural economy. Third, the analysis of land continuous cropping repair technology 3.1 Implementation of vegetable rotation In the process of planting vegetables, farmers must analyze the root growth requirements of vegetables to develop a scientific planting plan to avoid the occurrence of soil continuous cropping obstacles caused by single planting. In the vegetable growing process, the vegetable farmers must promptly treat the roots to absorb the same fertility. crop, avoid the absorption of fertility same situation occurs in the process of planting vegetables, such as crop rotation patterns to achieve in the process of planting vegetables, potatoes, tomatoes and other growing realization in turn, to ensure that the soil has a high productivity. 3.2 Carry out the corresponding deep fertilization The corresponding treatment of soil plays an important role in the process of vegetable cultivation. At this stage of agricultural production, this aspect must be taken seriously. The soil must be deep-turned at the end of each crop harvest, which can effectively treat the accumulation of toxins. A condition; the function of protecting the sputum can be achieved by effective deep-turning fertilization. According to statistics, the effective storage capacity of the soil can be increased by about 30%; the deep-turning treatment can make the organic fertilizer better. The value it deserves, so as to avoid the situation that the fertilizer has a decline in fertility during use. 3.3 fallow After planting one crop per year, after weaving and disinfecting the weeds and crop mandrels in the whole park, no other crops will be planted, so that the soil will be fully exposed to sunlight and rain, in the following year. Plants were planted again in February. 3.4 Take effective chemical measures In greenhouse cultivation process, such as watermelon plant Q1, Q3 in the acidification occurs, can take effective measures to chemically Under such circumstances, techniques such as the use of microbial agents in the early and vegetable cultivation, part of the organic fertilizer combined so as to effectively change the soil problem, you must pay attention to the survival of microorganisms in the process, to ensure that the soil has a high self-regulation, must pay attention to the ratio of carbon and nitrogen in the soil treatment process, only to ensure that the proportion maintained between the various elements of science Within the scope, the productivity of the soil can be fully utilized. Fourth, the conclusion The analysis of the continuous cropping obstacles is finished, and conservation and soil remediation are important ways to increase their productivity. In the process of vegetable planting, basic management must be done, and corresponding treatments must be done, such as implementing vegetable rotation, deep fertilization, fallow and other measures to ensure that the soil's own environment is at its best, effectively avoiding the past vegetable cultivation process. The problems in the process will gradually increase the productivity of the soil and ensure the steady and efficient development of the vegetable growing industry.
