- 摘要:
- 以早熟甜椒品种“甜杂1号”(A)和中晚熟甜椒品种“茄门”(B)为试材,分析了不同灌溉土壤水分上限(田间持水量的65%、75%、85%、95%、100%)下,温室甜椒的株高、茎粗、叶面积、根鲜干质量、茎鲜干质量、叶鲜干质量及全株鲜干质量等指标,以期制定温室甜椒高产栽培合理的灌溉定额。结果表明:不同灌溉土壤水分上限对甜椒幼苗的生长有显著影响。根、茎、叶、全株干质量均在土壤水分上限85%时达最大,株高适中,茎粗、叶面积及壮苗指数在土壤水分上限85%时最大。综上分析认为,在早春温室甜椒栽培中,土壤水分上限值以85%田间持水量,既有利于提高水分利用率,又可防止幼苗徒长达到壮苗的目的。
- Abstract:
- With early maturity varieties of sweet pepper ‘Sweet Mixed 1’ (A) and moderate sweet pepper varieties ‘Eggplant Gate’ (B) as test materials,the different irrigation upper limit of soil water (65%,75%,85%,95%,100% of field capacity) on the greenhouse pepper plant height,stem diameter,leaf area root fresh-dry weight,stem-fresh-dry weight,leaf fresh-dry weight,and whole plant fresh-dry weight of greenhouse sweet pepper were measured.In order to formulate a reasonable irrigation quota for high yield cultivation of greenhouse sweet pepper.The results showed that different irrigation soil moisture limit had significant influence on the growth of sweet pepper seedlings.The dry mass of root,stem,leaf and whole plant reached the maximum at the soil moisture limit of 85%,the plant height was moderate,the stem diameter,leaf area and seedling index were the maximum at the soil moisture limit of 85%.In conclusion,in the cultivation of sweet pepper in early spring,the upper limit of soil moisture is 85% of the field water capacity,which can not only improve the water utilization rate,but also prevent the seedling from growing to reach the goal of strengthening the seedling.
