(2) bleaching essence [character] bleaching essence is a white powder, smelly of chlorine, soluble in water and a small amount of sediment. Contains less impurities. It is relatively stable and not easy to decompose when exposed to moisture. The aqueous solution is alkaline, and the active ingredient of bleach is the same as that of bleach, which contains 60% of available chlorine, more than twice that of bleach. Bleach is also a broad-spectrum disinfectant with the same principle as bleach. It is also an encounter with aquatic products

Potassium should be sprayed on cotton leaves in August
As the content of available potassium (including water-soluble potassium and available potassium) in soil is decreasing year by year, available potassium has become the first major demand of cotton nutrition physiology. When 30 jin and 40 jin of high quality potassium fertilizer was applied to the base fertilizer, due to the consumption of cotton growth and development and the leaching after heavy rain, the content of available potassium in the soil would decrease to the original level in August. In August, with the deterioration of soil permeability and the decrease of soil temperature after ridge closure, soil potassium supply capacity is weakening day by day. If potassium fertilizer can not be replenished in time, it will show obvious potassium deficiency.

Extreme potassium deficiency in cotton fields will cause a large number of dead trees.
Cotton is sensitive to potassium deficiency, especially since the development of BT transgenic insect-resistant cotton, potassium-deficient cotton fields often show serious disease, premature senescence, few bolls, poor boll opening and poor fiber quality. Four or five years ago, the results of rapid measurement of available nutrients in cotton field soil in central and southern Hebei showed that the content of available potassium in most soil was less than 80PPM (mg / kg), which belonged to serious potassium deficiency, and some soils lacked 40PPM to the extent of extreme potassium deficiency. The data measured by the soil nutrient rapid measuring instrument are not accurate, and the content of available potassium in some soil samples is 0.
