How to scientifically manage water and fertilizer in the middle and late stages of rice?
How should water and fertilizer be managed in the middle and late stages of rice? Please provide an introduction to the management methods. Water and fertilizer management in the middle and late stages of rice can refer to the following: (1) Apply panicle fertilizer cautiously as appropriate to promote large panicles, full grains, and high yield. Based on the earlier rice seedling growth and field diagnosis results, for fields with high soil fertility, strong water and fertilizer retention capacity, many tillers, and darker leaves, delay, reduce, and lower the application rate of panicle fertilizer, generally applying 4-5 kg of urea per mu at the 5th-7th stage of panicle differentiation or at the penultimate leaf stage; for fields with poor fertilizer retention capacity, insufficient tillering, and lighter leaf color, appropriately increase the panicle fertilizer rate earlier, generally applying 6-8 kg of urea per mu at the 4th leaf from the top stage when entering the panicle initiation stage, and spray trace element fertilizers such as potassium dihydrogen phosphate on the leaves at the initial heading stage to increase grain filling and raise yield.

How to Fertilize Cauliflower Properly? A Detailed Guide to Scientific Fertilization Methods
How to fertilize cauliflower properly? Please give guidance. Cauliflower, also known as cauliflower (Brassica oleracea var. botrytis), has an edible portion that is a malformed flower head, and fertilization techniques differ depending on the variety. 1. Given that early-maturing varieties have a short growing season, the base fertilizer should be a quick-acting nitrogen fertilizer, applying about 8 kg of urea and about 8 kg of superphosphate per mu; for mid- and late-maturing varieties with a long growing season, the base fertilizer should be 1500 kg of barnyard manure, applied into the soil when tilling and preparing the land, followed by transplanting the seedlings. 2. Topdressing. In the early growth stage of cauliflower, frequently apply light applications of quick-acting chemical fertilizer as a 2% to 4% ammonium sulfate aqueous solution, about 700 kg per mu each time, or 10% to 30% human feces and urine, about 700 kg each time, applied around the roots. When the flower head begins to form, heavy topdressing should be applied to promote leaf and flower head growth. Apply about 800 kg of 40% human feces and urine per mu, or 10 kg of urea, about 20 kg of superphosphate, and about 8 kg of potassium sulfate, watered on.
