How to fertilize lotus root planting? Detailed explanation of fertilization methods
How can pollution-free lotus root cultivation achieve high yields? How should management be carried out? For pollution-free lotus root cultivation, you can refer to the following techniques: 1. Field selection: Choose low-lying wet fields with convenient irrigation and drainage, with yellow mud or blue mud soil being best. 2. Fine land preparation and sufficient base fertilizer: 1. To build soil fertility, you can use the method of turning under green manure, that is...
How should lotus root planting be fertilized? What kind of fertilization is more effectiveThe amount of fertilizer applied to the lotus root field base should be determined according to whether the soil is lean or fertile. Generally, choose fields with loose soil, fertility, rich organic matter, and convenient irrigation and drainage. Combined with land preparation, apply 2500-3000 kg of livestock manure per mu, 25 kg of diammonium phosphate; 10-15 kg of potassium sulfate, 50-100 kg of quicklime, 50 kg of superphosphate, and 150 kg of cake fertilizer, then rake level.
Topdressing is applied 3 times throughout the entire growth period of lotus root. The 1st time is applied when there are 1-2 standing leaves (about 25 days after planting), combined with intertillage and weeding, applying 3-5 kg of urea per mu or 750-1000 kg of human excrement and urine; the second time is applied when there are 5-6 standing leaves (about 40 days after planting, just before the rows close), applying 20-25 kg of compound fertilizer per mu, 5 kg of urea, or about 800 kg of human excrement and urine fertilizer; the third topdressing is carried out when the terminal leaf appears, when lotus root formation begins, that is, lotus root topdressing, applying 1000-1500 kg of excrement and urine fertilizer per mu, and 30-50 kg of cake fertilizer. The third topdressing mainly focuses on supplementing potassium fertilizer, applying about 10 kg of potassium sulfate fertilizer per mu, or spraying 0.2% potassium dihydrogen phosphate foliar fertilizer, spraying once every 7 days.
Fertilization should be chosen on clear and windless days, avoiding midday under the scorching sun. Keep the water level shallow to help the fertilizer penetrate into the soil, then irrigate back to the original depth. In deep-water lotus root fields, fertilizer is easily lost, so liquefied fertilizer cannot be applied directly. Solid fertilizer should be applied instead, that is, heavily applying green grass manure and burying it into the mud pond. When using chemical fertilizer for topdressing, first mix the chemical fertilizer thoroughly with river mud, make it into mud balls, and then apply them into the lotus root field.
