Five Key Points for Late-Stage Sweet Potato Management to Ensure a Bumper Harvest
After late August, summer sweet potatoes enter the critical period of tuber expansion. At this time, management should be strengthened. On one hand, the nutrients needed for tuber expansion should be met to the greatest extent possible; on the other hand, premature senescence of stems and leaves should be prevented, photosynthesis should be enhanced, and nutrient accumulation should be increased. Specific yield-boosting technical recommendations are as follows

Three key stages to grasp in rice film seedling raising
Based on many years of practical experience, I believe that three key stages should be noted in the technique of raising rice seedlings under film: the closed stage, the hardening stage and the film-removal stage. The first stage: the closed stage, that is, from sowing to the one-leaf-one-heart stage. During this period the film must be tightly closed to create

Four key techniques to grasp in the management of cotton during the boll-opening stage
Grasp the "four key techniques" in cotton management during the boll-opening stage (skillfully manage fertilizer and water, skillfully prune, skillfully pick rotten bolls, skillfully promote ripening). 1. Skillfully manage fertilizer and water to promote nutrient transport. First, foliar topdressing. For cotton fields where leaves lose green too early and show premature aging due to nutrient deficiency, spray 50-60 kg per mu of 1%-2% urea solution onto the leaves to extend the functional period of the leaves. For cotton fields that grow too vigorously and show late maturity with excessive vegetative growth, foliar spray 0.2% potassium dihydrogen phosphate solution or 0.3% superphosphate soaking liquid to promote nutrient transport and help improve boll opening. Second, prevent autumn drought.
