摘要
针对日光温室辣椒膜下滴灌,选择灌水定额、灌水周期、灌水次数作为试验因素,开展完全组合的膜下滴灌灌溉制度试验研究。日光温室冬春茬辣椒全生育期共持续180～215 d,适宜的灌水次数为30～38次,平均灌水周期为5～6 d,灌水定额为255～270 m3/hm2,全生育期适宜的灌溉定额为7 500～9 750 m3/hm2,产量11.55×104kg/hm2以上。
In view of the sunlight greenhouse hot pepper drip irrigation under membrane,choice of the irrigating quta,irrigation cycle,irrigation times for the experimental factors,the paper carried out complete combination of experiment of irrigation schedule by drip irrigation under membrane.Whole grow season of the winter and spring hot pepper in sunlight greenhouse was about 180-215 days,the suitable irrigation times was 30-38,the average irrigation intorval was 5-6 days,the irrigating quota was 255-270 m^3/hm^2,the suitable irrigation norm was 7 500^-9 750 m^3/hm^2 in whole growing season.The output was above 11.55×10^4 kg/hm^2.
