How can the boll-setting rate be increased in cotton cultivation?
Types of square and boll shedding in cotton include physiological shedding, shedding caused by pests and diseases, and shedding caused by mechanical damage. As for the causes of physiological shedding: first, excessive application of fertilizer and water causes excessive vegetative growth, with nutrients consumed too heavily in the early stage and supply falling short of demand in the later stage; second, excessive planting density in the cotton field causes severe shading by branches and leaves, reducing light, weakening photosynthesis, and decreasing the nutrients produced; third, some cotton fields are deficient in boron, causing cotton to flower but not set fruit; fourth, high temperature and drought, insufficient fertilizer and water, or excessively high temperatures cause cotton pollen sterility; fifth, frequent rainy weather leads to poor pollination. As for pest and disease damage, inadequate control of cotton mirids, cotton bollworms, Fusarium wilt and Verticillium wilt can easily lead to massive square and boll shedding. As for mechanical damage, it is mainly caused by improper operation during field management. In addition, in the past two years, blind application of herbicides has occasionally caused square and boll shedding.
