- 摘要:
- 以辣椒为试材，在大棚内采用盆栽方式，利用微润交替灌溉方法，设置1.0、1.5 m压力水头2个处理，并以普通灌溉为对照，分析了不同处理下辣椒的生长发育情况、产量及土壤含水率，探讨了不同压力水头对辣椒生长的影响。结果表明：微润交替灌溉处理组（1.0、1.5 m压力水头）辣椒的株高、鲜质量、干质量和产量等均高于普通灌溉组，灌溉水分生产率分别为普通灌溉组的1.53倍和2.22倍。在交替周期均为4 d的条件下，1.5 m压力水头更有利于辣椒的生长。因此微润交替灌溉不仅能应用于辣椒种植，且选择合适的压力水头可以在节约灌溉用水的同时提高辣椒产量。
- Abstract:
- Pepper was used as test material,using potted plants and alternate micro-irrigation methods in greenhous,two different treatments of 1.0 m pressure head and 1.5 m pressure head were set up,using ordinary irrigation as the experimental control,the growth and development,yield of pepper and soil water content under different treatments during the whole growth process of pepper were analyzed to obtain the effect of different pressure heads on crop growth.The results showed that the plant height,fresh weight,dry weight and yield of the pepper in the alternate irrigation group were all higher than those in the ordinary irrigation group.Irrigation water productivity of 1.0 m and 1.5 m pressure head were 1.53 times and 2.22 times that of the normal irrigation group,respectively.Under the condition of 4 days alternating period,the 1.5 m pressure head was more conducive to the growth of pepper.Therefore,alternate micro-irrigation could be applied not only to actual pepper planting,but also to select appropriate pressure heads to save irrigation water while increasing yield.
