Drought and locust plagues are the most common and serious natural disasters in the cotton production process. Both have great impact on cotton production and quality.
There are three main hazards of drought to cotton growth and yield: First, under drought conditions, the cotton plants become shorter, the leaf area becomes smaller, and the growth rate of bolls becomes slower. Second, under the conditions of drought, the normal physiological metabolism of cotton plants was affected, and the synthesis, supply, and distribution of nutrients in the cotton plants were hindered. As a result, a large number of flower buds fell off, and the more severe the drought, the higher the bell rate. Third, under the conditions of drought, the number of bolls per plant and boll weight decreased, and the length, strength, elongation, and uniformity of the fibers decreased, and the quality deteriorated.
There are also three aspects of damage to cotton growth and yield: First, cotton field flooding destroys the coordination and balance of water, fertilizer, gas, and heat in the cotton field, resulting in a serious shortage of soil air, inhibiting the respiration of the root system, and reducing the absorption capacity. Root growth slows down. At the same time, locust damage caused topsoil compaction and nutrient loss, soil aerobic microbial activity was inhibited, and anaerobic microbial activity increased, resulting in a large number of toxic substances, directly poisoning the roots of cotton, and causing roots to become black and rot. Second, locust damage causes soil hypoxia, which not only reduces the ability of root absorption, but also does not allow the synthesis of roots. The synthesis of amino acids, cytokinins, and other organic substances in the roots is reduced, resulting in cell division, elongation, differentiation, and other growth processes. Inhibit and hinder the growth and development of cotton plants. Third, locust damage caused the roots to reduce the ability to absorb fertilizer and water, and the transpiration of the aboveground parts of the leaves continued to be carried out. The water balance in the cotton plants was destroyed, and the physiological metabolic functions such as photosynthesis and transport of substances were hindered, resulting in the sudden increase of bells and bells. Reducing weight, production and quality decline.
Is there any good way to reduce or avoid the harm caused by droughts and plagues, and to make cotton high quality and high yield?
High-tech products Soil Active high-level ecological conditioning fertilizers - high ground-level irrigation can also reduce the harm of drought or flood disasters while achieving no-tillage. It is a new type of soil conditioner with high efficiency, safety, non-toxic and unique mechanism of action. It is organically combined with soil particle structure accelerator and soil activator. After applying high ground in cotton fields, not only can the plough layer be deepened, the soil can be loosened, and the compaction can be completely eliminated. Moreover, it can resist heavy cropping, drought resistance, cold resistance, fertilizer retention, water conservation, heat preservation, promote cotton growth, make the roots of cotton plants grow deeply, and reduce the cost. , Inhibit soil-borne diseases, improve cotton quality, and increase cotton yield. Shigeao is the preferred fertilizer for the production of pollution-free agricultural products and is the best alternative for traditional fertilizers.
