７～８月稻田管理应注意的问题一、科学用水：春稻经过一阶段烤田蹲苗后，已达到叶色转淡，长势稳健的稻田，要分别先后进行复水，采取间歇灌溉；麦茬稻要根据不同情况，已达到预定计划的穗数（抛秧田达到７０％时），要抓紧时间落干（个别污水灌区、长势过旺的稻田要进行...
7-8 months of paddy field management should pay attention to the problem First, the scientific use of water: After a period of spring rice paddy field squatting, has reached the leaf color downturn, steady growth of the paddy fields, respectively, to rehydration, to take intermittent irrigation; stubble rice According to different circumstances, has reached the planned number of spikes (throwing seedlings reached 70%), we must pay close attention to time off (individual sewage irrigation, growing rice fields to carry out ...
