摘要
根据日光温室黄瓜不同生育期的需水特征,选择灌水量和灌水周期作为试验因素,开展日光温室黄瓜膜下滴灌灌溉制度试验研究。日光温室春茬黄瓜全生育期持续92 d,适宜的灌水次数为15～16次,平均灌水周期为5～6 d,次灌水量为267～271 m3/hm2,全生育期适宜的灌溉定额为4 065～4 275 m3/hm2,产量可达9.9万kg/hm2以上。
According to the water equirements of nectarine in different phenologies in sunlight greenhouse,the paper chose irrigation quantity and the irrigation time as the experimeutal factors and set up different irrigation treatments and carried out the experimatnt of drip irrigation schedule.Which can supply the technical support for the Nectarine growth in greenhouse.The results showed that the growth period in sunlight greenhouse,nectarine last about 365 days,the suitable irrigation times is 22,the average irrigation interval is 16 days,the mean irrigation quota is 185 m3/hm2 and the yearly irrigation norm is 4080 m3/hm2,the yield of nectarine can be reached more than 30 000 kg/hm2.
