How should late-stage premature senescence in cotton be managed to prevent and control it?
How can management prevent and control late-stage premature senescence in cotton? Please provide methods. To prevent and control late-stage premature senescence in cotton, you can refer to the following methods: 1. Fertilizer and water management: According to the condition of the cotton plants, the climate and the soil conditions, apply the flowering and boll fertilizer heavily; if the flowering and boll fertilizer is insufficient, then apply a top-dressing fertilizer. After mid-August, if the maximum field water-holding capacity is below 60%, and in early September below 55%, water promptly to promote fertilizer with water and ensure the fertilizer effect is exerted in time. If cotton premature senescence is caused by soil potassium deficiency, while applying base fertilizer, increase the application of potassium sulfate or potassium chloride by 5-10 kg during the seedling and bud stages. When fertilizing, be sure to plow deeper than 20 cm, apply the fertilizer at the plow bottom, achieve deep fertilizer application, promote root penetration downward, reduce fertilizer loss, and improve fertilizer use efficiency. During the flowering and boll-setting stage, if drought occurs, water lightly, carefully clean the furrows and beds to prevent waterlogging again; if waterlogging occurs, drain promptly.

What should be noted when growing pollution-free tea?
How should early spring tea be managed? Please guide the management methods for early spring tea as follows: 1. Weeding and loosening the soil: After 4-5 months of rain and snow, the tea garden soil has become compacted, and some areas have already grown green weeds.

How should seed fertilizer be applied reasonably when sowing summer corn?
How should seed fertilizer be applied when sowing summer corn? Please give an introduction. The main reasons why improper application of seed fertilizer when sowing corn causes bud burn and seedling burn: First, the amount of seed fertilizer applied is too large, causing the seeds or the root system during emergence to come into contact with chemical fertilizer, resulting in seed burn and seedling burn. Second, the seed fertilizer is mixed with the seeds during sowing, and although the amount of seed fertilizer applied is not too large, because the seeds and fertilizer are mixed together during sowing, the seeds and fertilizer come into direct contact, causing seed burn and seedling burn.
