At present, most cottons have entered the flowering or flowering period. This period is one of the most important periods for cotton production. It is the most vigorous and most fragile period in cotton life. It is the most vulnerable to the damage of cotton bollworms and other pests. The infestation of pathogenic bacteria caused falling flowers and falling bells. During this period, the growth of cotton was greatly affected by the environmental climate, and it was sensitive to the demand of water and fertilizers. It was the period with the most demand for fertilizer and water. Therefore, special attention should be paid to the production for this period. The most prone problems of cotton during flowering and bolling period: 1Because of the poor field permeability after the enclosure, the light is affected and the photosynthesis effect is reduced. At the same time, the oxygen in the root system is insufficient to affect the growth and development of the roots; 2 The bollworm, red spider and other pests Serious damage. Due to the quality of the cotton boll shell during this period, the cotton boll is young and juicy, so it is susceptible to insect pests; If there is too much rain, the peach will be unfavorable, and it will be prone to diseases, resulting in rotten bells and black bells. If the weather is arid, it will affect fertilization, and it will easily produce a lot of bells. 4 The irritability of fertilizer and water, excessive fertility, proneness to madness, and fertilizer Insufficiency is likely to cause a large number of aborted bells to fall off, causing premature aging and affecting cotton yield and quality. Field management points: 1 Drought relief, do a good bubble system, to avoid the impact of drought or flooding cotton growth; 2 Rational fertilization to meet the needs of water and fertilizer, so that plants grow robust and prevent mad grow; 3 control pests and diseases, focus on anti-cocoon bollworm, red spider Diseased guests and physiological diseases caused by pests and various pathogens, to avoid causing a large number of falling flowers and falling bells due to pests and diseases; 4 Pruning pruning to avoid nutritive waste, appropriate control of the closure line, enhance the field ventilation and invitability; 5 spray leaf surface Fertilizers, such as the Cotton Special Spraying Room, can increase photosynthesis capacity, enhance root vigor, increase budding, flowering, and ringing speeds, shorten the bud and boll period, reduce the shedding of bolls, increase bud growth, protect bells, and prevent drought. Decline and late maturity increase cotton yield and quality.
