The saline-alkali land has high salt content and high alkalinity, so that the soil humus is leached and the soil structure is destroyed. It is sticky when wet and hard when dry. There are often white salt accumulations on the soil surface, poor ventilation and water permeability, and serious problems will cause plants. Wilting, poisoning and rotten roots die, so the saline-alkali soil must be improved. The principle of improving saline-alkaline soil is to actively fertilize the soil while draining, isolating and preventing salt. The following are specific measures for the application of strains to the improvement of saline-alkali soils.
Saline-alkali land improvement measures:
1. Drain and wash salt. Draining and washing salt is to pour water into the saline-alkali soil to dissolve the soil salt, and drain the soluble saline-alkali in the topsoil layer into the deep soil through infiltration or leaching out, and then infiltrate it into the drainage ditch to remove it.
2. Level the land. Leveling the land can make the water infiltrate uniformly, improve the effect of raining and irrigation to wash the salt, and prevent soil patchy salinization.
3. Deep ploughing and deep turning. The distribution of salt in the soil is that the surface layer is more and the lower layer is less. After ploughing, the salt in the top soil can be buckled to the bottom of the plough layer, and the soil with less salt in the lower layer can be turned to the surface. Plowing can loosen the cultivated layer, cut off the soil capillary, reduce soil moisture evaporation, and effectively control soil return to salt. The best time for plowing saline soil is spring and autumn. Spring and autumn are the seasons when the salt returns to heavier. Plowing in autumn is especially beneficial for killing pests and eggs, removing weeds, burying roots and stubble deeply, strengthening the decomposition of organic matter and the release of late-acting nutrients, so it is worth promoting.
4. Rake the ground at the right time. Harrowing the ground can loosen the topsoil, cut off the soil capillary water to transport salt to the surface, and play a role in preventing salt return. The harrowing of the land should be timely, with shallow spring ploughing, rush ploughing, early autumn ploughing, dry ploughing instead of wet ploughing.
5. Increase the application of bio-organic fertilizer fermented by biological bacteria, and rationally use chemical fertilizers. Saline-alkali land generally has the characteristics of low temperature, thin soil and poor structure. For example, the golden fungus bio-organic fertilizer is decomposed and transformed into humus, which can improve the buffering capacity of the soil, and can react with sodium carbonate to form sodium humate and reduce the alkalinity of the soil. Sodium humate can also stimulate crop growth and enhance salt resistance. Humus can promote the formation of agglomerate structure, thereby increasing the porosity and water permeability, which is conducive to salt leaching and inhibits salt return. Organic matter produces a large amount of organic acids during the decomposition process, which can neutralize the alkalinity of the soil on the one hand, and accelerate the decomposition of nutrients on the other hand, promote the conversion of late-acting nutrients, and improve the availability of phosphorus. Therefore, increasing the application of bio-organic fertilizer is an important measure to improve saline-alkali soil and improve soil fertility.
6. Apply probiotics. Generally, the soil environment of saline-alkali soil is harsh, and many harmful bacteria will breed, which is a vicious circle in the soil. On the one hand, the application of such as golden bacteria can inhibit harmful bacteria, release nutrients in the soil, enrich soil nutrients, etc., on the other hand, it can absorb the salt in the soil into organic matter, and neutralize the alkalinity of the soil, fundamentally Solve the problem of soil salinization.
In short, the improvement of saline-alkali soil requires a multi-pronged approach. At the same time, the use of bacterial agents can increase the rate and quality of saline-alkali soil improvement, so that the soil can form a virtuous circle, fundamentally solve the problem of soil salinization, and promote agricultural health and effectiveness. Continuous development.
