旱稻是指在旱地上种植和生长的稻子,它不需建立和保持水层,人们只是根据其生长发育需要予以适时适量灌溉.近年国内有关研究表明,我国华北、东北一季春稻旱作,在5—9月份降雨500毫米的情况下,生育期间每亩灌水200米~3,亩产稻谷400公斤以上;华北麦茬旱作稻,在7—8月份降水250毫米左右时,生育期间亩灌水200—100米~3,亩产稻谷250公斤左右.我们1986—1987年在南北疆10个点试验也表明,春早稻生育期间浇水10—12次,亩灌量500米~3,亩产稻谷250公斤以上;麦茬早稻生育期间浇水5—6次,亩灌水量300—400米~3,亩产稻谷200公斤以上.旱稻的总灌水量与冬小麦和夏玉米差不多.
Upland rice is planted and grown in the dry land of rice, it does not need to establish and maintain the water layer, people just according to their growth and development needs to be timely and appropriate irrigation.In recent years, the domestic studies show that the spring season in North China, May-September rainfall of 500 mm in the case of fertilization during the fertilization period of 200 meters to 3, more than 400 kilograms of rice per mu; North China wheat cropping paddy, precipitation in July-August when about 250 mm, during the growth of 200 acres of irrigated 200 -100 meters ~ 3, about 250 kilograms of rice per mu.We 1986-1987 in the northern and southern Xinjiang 10 points test also showed that during early spring rice watering 10-12 times, 500 acres of irrigated 500 acres per mu Rice 250 kg or more; wheat stubble early during the growth of watering 5-6 times, mu irrigation 300-400 m ~ 3, 200 kg per mu of rice more than the total amount of irrigated rice and winter wheat and summer maize almost.
