1X19 Stainless Steel Wire Rope
The steel wire rope plays the role of bearing the load, and its performance is mainly determined by the steel wire. The steel wire is a round (or special-shaped) wire made of stainless steel, carbon steel or alloy steel by cold drawing or cold rolling. It is used to increase the elasticity and toughness of the steel wire rope, lubricate the steel wire, reduce friction and improve the service life. Commonly used rope core organic fibers (such as hemp, cotton), synthetic fibers, asbestos core (high temperature conditions) or soft metals and other materials. Folding type 1. Round strand wire rope 2. Braided wire rope 3. Flat wire rope.

First, the characteristics of occurrence. In autumn and winter, cotton leaves are wintering in winter, green weeds, weeds, soil seams, and litter. The next year begins in late February to early March, first in winter or early spring. After the cotton seedlings are unearthed, they are moved to the cotton field for damage. Cotton leafhopper on weeds is the main source of cotton fields. Every year in mid-June, the peak of nursery hazards is the most serious damage to wheat stubble cotton. From mid-July to mid-August, Fuxi harms cotton leaves. In the middle of September, late-onset, late-onset cotton field cotton leafhopper can also be harmful. Weather is the primary condition affecting the occurrence of cotton leafhoppers. The weather is hot and dry, there is no rain, and the cotton leafhopper will occur in a large area, causing the leaves to turn red and the deciduous poles. Heavy rain and heavy rain have a certain scouring effect on cotton leafhoppers, which can quickly reduce the density of insect populations, and inhibit and reduce the damage of cotton leafhoppers.
Second, prevention and control measures 1, agricultural control. In the early spring, clearing weeds reduces the source of sputum. Cultivate strong seedlings, increase compound fertilizer application, and improve the insect resistance of cotton plants. It was found that the leaves of the buds were removed and removed in time to prevent the spread.
2. Chemical control. When the cotton field has a rate of 3-5%, the control should be carried out. Found a circle, found a bit of a piece, you can choose 800-1000 times of dicofol, choose to prevent after the dew dry or in the evening, enhance the efficacy, improve the killing effect, and evenly spray to the back of the leaves, do There is no diseased plant in Daejeon, and the diseased plant does not leave diseased leaves. In order to prevent the resistance of cotton leafhoppers, it is necessary to use a broom, a killing agent and other acaricides. It can also promote the use of "avermectin" to control cotton leaf mites. "Avermectin" can be applied positively to achieve the effect of the opposite side of the dead insects, the control is simpler and easier, and the prevention period is long and the effect is stable. 
Cotton leafhopper, also known as cotton red spider, belongs to the arachnid, the genus Aphid, the leaf worm, and all cotton areas. In addition to harming cotton, it also harms corn, sorghum, wheat, soybeans, etc. The host is extensive. Cotton leafhopper mainly sucks juice on the back of cotton leaf surface, causing yellow spots, red leaves and fallen leaves to appear on the leaf surface. It is similar to "fire dragon". In the year of the outbreak, it caused a large area of ​​production reduction or even no harvest. It can be harmful during the entire growth period of cotton.
