| 摘 要： | 青椒是温室中常见的一种蔬菜,为探求青椒灌溉制度,进行日光温室滴灌条件下灌水下限对青椒生长影响试验。结果表明:土壤含水率变化幅度随深度增加而减少,表层波动剧烈,深层变化平缓。对于不同层土壤含水率的变化规律:处理1处理2处理3CK。处理1、2、3和CK全生育期耗水量为228.3、271.7、345.2和440.1 mm,青椒苗期日均耗水量0.3~1.0 mm/d,初花初果期0.7~2.2 mm/d,盛果期2.4~5.3 mm/d。在整个生育期内株高、茎粗的变化为:处理2处理3CK处理1。滴灌处理1、2、3和对照沟灌青椒产量分别为60.0、106.413、103.062和78.07 t/hm2。对应灌溉水分生产率分别为29.77、35.94、31.481、7.73 kg/m3。综合因素分析,日光温室青椒在滴灌条件下,处理2为最佳灌溉方案,可得到高产、省水的效果。

| Abstract: | Green pepper is one kind of common greenhouse vegetable.In order to search the green irrigation scheme,the test for effect of lower limit of drip irrigation quantity on growth of green pepper is conducted in the greenhouse.The results show that the variation amplitude of soil water content decreases with the increase of soil depth,the surface change acutely while the deep layer changes gently.The sequence of water content in different layer from small to large is treatment1,treatment2,treatment 3,CK,respect... |
