一、水浇地免耕节水灌溉模式 该模式为一年两收,上茬小麦,下茬玉米等作物。节灌的主要措施是:选节水抗旱品种或抗旱保水剂拌种,并与增施有机肥、平衡施肥相结合。通过将水源(机井、塘坝、蓄水池等)以下各级渠道建成水泥防渗渠和平整土地(达到上略高,下头略低),长畦变短畦,宽畦变窄畦,大畦变小畦,免耕播种等节灌措施的综合运用。 First, irrigated irrigated water-saving irrigation mode The model for two crops a year, on the crop of wheat, corn and other crops next crop. The main measures of irrigation are: water-saving drought-resistant varieties or water-resistant drought seed dressing, and with the addition of organic fertilizer, combined with balanced fertilization. Through the water sources (wells, ponds, reservoirs, etc.) into the following channels at all levels of cement seepage canal and the formation of land (to achieve slightly higher, slightly lower head), long 畦 short 畦, wide 畦 narrow 畦, 畦 large 畦Small 畦, no-tillage sowing and other measures of integrated irrigation.
