摘要
研究了水浆管理对水稻氮代谢和褐稻虱种群的影响,结果表明:在淹水状况下,稻株在生殖生长阶段碳、氮代谢失调,氮代谢偏强,碳代谢偏弱,这不但影响稻株中碳水化合物的有效积累,造成减产,同时也有利于褐稻虱种群发生。
Effects of water management on rice plant metabolism and brown planthopper (Nilaparvata lugens) population development were studied in the paper. In continuous flooding area, imbalance of nitrogen metabolism and carbonhydrate metabolism had been checked in rice plants since the beginning of reproductive growth: nitrogen nutritional level was too high, and cabonhydrate level too low. This nutritional imbalance might not only affect the carbonhydrate accumulation in rice plant, but also stimulate the BPH population development.
