探讨了再生稻的吸肥特点是:吸肥量大而早,从头季稻收割到再生稻齐穗,30多天时间内,所吸收的氮、磷、钾养分占一生中吸收总量的80%—90%。土壤供肥力及稻桩中养分的贮存量,直接影响再生稻的萌发和出苗。抓住头季稻收剖前5—10天,每亩配合施用氮素8kg,p_2o_54kg,k_2o_8kg,是夺取再生稻高产的关键。 The absorption characteristics of ratooning rice were discussed as follows: the amount of fertilizer absorbed was large and earlier, and the harvest of nitrogen, phosphorus and potassium absorbed from the first crop of paddy to the ear of ratooning rice within 30 days, accounted for 80 % -90%. Soil fertility and storage of nutrients in rice piles directly affect the germination and emergence of ratoon rice. Seize the first crop of rice 5-10 days before harvesting, with the application of nitrogen per mu 8kg, p_2o_54kg, k_2o_8kg, is the key to capture high yield of ratoon rice.
