水稻旱种湿管种植技术是解决水源困难,节水种稻的有效措施。为科学用水,提高效益,我们于1984年至1986年,以苗期旱长、中期和后期湿润灌溉为基础,进行了灌溉水量和灌溉方式试验,以期确定高效益灌溉水量及各生育阶段的灌水量。试验设计 1984年设每亩100、200、300、400和800立方米五个灌水量及湿润、间歇、喷灌、淹水和覆盖地膜湿润灌五种灌溉方式。 1985年在两种肥力条件下,设每亩300、 Rice dry cultivation wet pipe planting technology is to solve the water source difficulties, water-saving rice effective measures. In order to scientifically use water and improve the efficiency, we conducted experiments on irrigation water amount and irrigation methods based on the wet, dry and mid-term and late-stage irrigation periods from 1984 to 1986 in order to determine the irrigation water amount for high-efficiency irrigation and irrigation during each growth period the amount. Experimental Design In 1984, five irrigation amounts of 100, 200, 300, 400 and 800 cubic meters per mu and wetting, intermittent, sprinkling, flooding and plastic film mulching wet irrigation were set up. In 1985 under two fertility conditions, set 300 per acre,
