| 摘 要： | 为探讨日光温室滴灌条件下青椒最佳灌水下限组合,通过小区试验方法分析了滴灌条件下5种不同灌水下限组合对青椒形态、品质、产量及灌溉水利用效率的影响.结果表明:不同灌水下限组合对青椒株高、茎粗、VC含量影响差异显著.对青椒产量的影响差异不显著.采用主成分分析法对各灌水下限组合进行了量化的综合评价.评价得分显示:当青椒苗期、开花着果期及结果期的水分下限分别控制在田间持水量的50%～60%、50%～60%、70%～80%时得分最高,表明该处理下青椒产量最高、品质最佳、灌溉水利用效率最高,其为青椒最佳灌水下限组合.

| Abstract: | In order to determine the lower limit of the most appropriate soil moisture of the greenhouse pepper under drip irrigation,the field experiment was conducted and the effect of 5 soil moistures of different kinds on green pepper shape,quality,yield and irrigation water use efficiency was analyzed.The results show that different soil moistures have a significant effect on plant height,stem diameter,VC content of pepper.But pepper yield is not significant.The results of a comprehensive evaluation based on prin... |
