Abstract:
Taking ‘Qinghai chili pepper No.1’ as material，the effect of different irrigation amounts (562,437,312,187,62 m3/hm2) on growth and yield of chili pepper in Qinghai Academy of Agriculture and Forestry Experiment Station solar greenhouse were conducted，the soil moisture，soil conductivity，soil temperature，botany and yield traits of chili pepper were analyzed under different treatments.The results showed that in an irrigation cycle，the soil moisture presented overall downward trend in each treatment.The soil conductivity of 562,437,312 m3/hm2 treatments rendered high-low-high trend and 187,62 m3/hm2 treatments changed relatively gentle，without significantly raising and lowering trend.The soil temperature increased with the reduction in the amount of irrigation.The plant height，stem diameter and yield had obvious difference under different irrigation amounts.From the water-saving efficiency mode，312 m3/hm2 treatment was the most economical irrigation amount.
