随着水稻高产栽培技术研究的深入,传统的管水技术有的已不再适应水稻高产的需要。过去根据水稻生理需水与生态需水的规律,水稻本田期传统的管水技术,基本上是浅水插秧;深水活棵;薄水分蘖;足水长穗;干湿交替结实。此技术虽然能较好地满足水稻整个生育期的生理需水,但是有的环节往往会影响 With the deepening of research on high-yielding cultivation techniques of rice, some traditional tube-water technologies no longer meet the needs of high-yielding rice. In the past, according to the law of physiological water requirement and ecological water requirement of rice, the traditional water management technology in Honda during the rice period was basically shallow water transplanting, deep water living trees, thin water tillers, long panicles of water and alternate wetting and drying. Although this technology can better meet the physiological needs of rice throughout the growth period, but some aspects tend to affect
