Last Updated: 2024/11/08, Lesser Heat and Greater Heat are in July. This month is the hottest month of the year. It is necessary to do a good job in flood control, summer heat prevention and drought relief, timely rush harvest of early rice, application of tiller panicle fertilizer in middle rice, loosening soil, topping, applying flower fertilizer in cotton, and controlling red bollworm and cotton lacewing insects. Rush to plant late autumn crops at the right time. Do a good job in ventilation and cooling of livestock and poultry cages to prevent human and animal heatstroke. Most of the cotton fields in our province are in a state of dark stains at present. At present, cotton is in the most critical period of transformation from vegetative growth to reproductive growth, and it is also the most critical period for the increase of cotton buds and bolls, so emergency management should be taken immediately.

Dig three trenches deep. Quickly remove clear water and reduce waterlogging in cotton fields. Dredge the box groove and waist groove in time. The outlet must be deep so that all the water can flow into the branch ditch, and the branch ditch should remove the drainage obstacles in time.

Look at the fields and fertilize. At present, cotton is in two states: one is waterlogging water control type, the other is multi-Rain Water hairstyle. First, waterlogging water control type. Mainly refers to three types of seedling fields and cotton fields flooded for more than 36 hours, it is necessary to apply available nitrogen fertilizer, 10 kg urea or 15 kg diammonium phosphate per mu. Second, more than Rain Water hairstyle. The long-term heavy rain inhibited the reproductive growth of cotton, the vegetative growth of cotton was too prosperous, the cotton plant grew excessively, and the bud and boll fell off seriously. For watery cotton, it is necessary to reduce the amount of fertilizer, especially available nitrogen fertilizer. Flower and boll fertilizer must be applied when cotton growth weakens and each plant sits on 1 Mel and 2 big peaches. Due to the serious loss of nitrogen, potash and micro-fertilizers in long-term flooded cotton fields, peach fertilizer must be re-applied. 25 kg urea, 15 kg potassium chloride, 1 kg boron fertilizer and 1 kg zinc fertilizer were applied to peach fertilizer per mu. Combined with fertilization for cultivation.
