Generally, about 10 cultivars of water should be applied to the seedlings, about 2-3 kg of potash fertilizer and about 8 kg of ammonium bicarbonate, accounting for the total fertilization. About 15% of the volume.
Meng Shi ear spike fertilizer should be a big horn from the top of the corn or hand can touch the best fertilizer when applied to smallpox, early application of weak seedlings, strong seedlings later, usually with 30-40 per mu water dung, plus ammonium bicarbonate 20- 25 kg mixed superphosphate 25-35 kg.
