摘要
就焉耆县大田色素辣椒膜下滴灌,进行了试验研究。色素辣椒全生育期总灌溉次数为14次,总灌水量为3 150m3/hm2,灌水定额均为225m3/hm2,灌水周期为9d。定植-开花期42d(5月20日-6月30日),灌水5次,该阶段灌水量为1 125m3/hm2;坐果期41d(7月1日-8月10日),灌水5次,阶段灌水量为1 125m3/hm2;成熟期36d(8月11日-9月5日),灌水4次,阶段灌水量为900m3/hm2;采收期10d(9月6日-9月15日),不灌水。色素干辣椒产量为5 745kg/hm2。
In this paper, the experimental study on irrigation scheduling of pigment pepper under drip irrigation under mulch was con- ducted in Yanji county of Xinjiang. In the whole growth period, the total irrigation times was 14, the total irrigation water quantity was 3 150 m^3/hm^2 , the irrigation quota was 225 m^3/hm^2 , and the irrigation cycle was 9 days. In the 42 days from planting to flow ering period, from May 20 to June 30, the irrigation times was 5 and the irrigation water quantity was 1 125 m^3/hm^2. In the 41 days of flushing period, from July 1 to August 10, the irrigation times was 5 and the irrigation water quantity was 1 125 m^3/hm^2. In the 36 days of mature period, from August 11 to September 5, the irrigation times was 4 and the irrigation water quantity was 900 ma/hm^2. In the 10 days of picking time, no water was irrigated. The yield of dry pigment pepper was 5 745 kg/hm^2 .
