被水稻专家称为“农业灌溉方式革命”的水稻控水增产技术,已在湖南省快速推广到66.7万公顷。 水稻控水增产技术是根据水稻不同生育阶段对水分的不同需求,合理控制田间水分,确保对水稻的最佳供水,避免和减少水肥流失的一项节水灌溉新技术。按照这一新技术的要求,水稻在其生育期间除插秧至返青和治虫时才允许田间有水层外,从开始分蘖至收 Rice control and stimulation technology, which is called “Revolution of Agricultural Irrigation” by rice experts, has been rapidly popularized to 667,000 hectares in Hunan Province. Water control and paddy production technology is a water-saving irrigation technology based on the different needs of water at different stages of rice growth, reasonable control of field moisture, to ensure the best water supply to rice, to avoid and reduce the loss of water and fertilizer. In accordance with the requirements of this new technology, in addition to transplanting rice and controlling pests, paddy rice is allowed to have a water layer in the field during its growing period.
