- 摘要:
- 以“青线椒1号”为试材，在青海省农林科学院试验站日光温室内进行了单次562、437、312、187、62 m3/hm2 5种不同灌溉量对线辣椒生长发育及产量影响的试验,测定分析了不同处理下土壤含水率、土壤电导率、土壤温度及线辣椒植物学性状和产量性状的变化。结果表明：在1个灌水周期内，各处理土壤含水量总体呈下降趋势；562、437、312 m3/hm2处理下的电导率呈现高-低-高的变化趋势，187、62 m3/hm2处理下电导率随时间变化的趋势较为平缓，没有明显升高或降低的趋势；土壤温度随灌水量的减小而升高；不同灌溉量下辣椒株高、茎粗、产量差异显著；从节水高效模式来看，312 m3/hm2的灌溉处理为最经济灌水量。
- 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.
