Irrigation Scheduling of Cucumber under Mulched Drip Irrigation in Solar Greenhouse

In order to obtain ideal drip irrigation scheduling of cucumber under plastic mulch in solar greenhouse,cucumber with 4 treatments and 3 repetitions treatment as experimental materials.An experiment was carried out to study the irrigation pattern for drip irrigation cucumber under mulch in solar greenhouse by determining soil water,morphological indexes and yield of cucumber and irrigation amount.It is showed that treatment 4 has the largest yield.While in order to attain high yield,good quality and high efficiency of water use at the same time,the total water amount must be controlled about 120 mm for cucumber drip irrigation under mulch in solar greenhouse and consumption intensity of every day is 3.04～4.68 mm.It is irrigated every 4 days with water amount of 15 mm for each time during the whole stage and ideal soil water content is 85%～95% of field water holdup.
