潜水埋深对疏叶骆驼刺(Alhagi sparsifoli)幼苗生长和叶片形态的影响/Effects of Water Table Depth on Leaf Morphology and Growth of Alhagi sparsifolia Seedlings[J]

open access: yes, 2014
研究了潜水埋深(40、80、120、180、220 cm)处理对一年生疏叶骆驼刺(Alhagi sparsifoli)幼苗生长和叶片形态的影响.结果表明:随着潜水埋深的增加,疏叶骆驼刺幼苗叶片厚度逐渐增加,叶片厚度在220 cm埋深下最大,长度和宽度在120 cm埋深下最大,且叶片长度呈优先减小的趋势;潜水埋深变化对疏叶骆驼刺株高生长影响不大,但对冠幅和分枝数的生长影响显著(p<0.05);除40 cm埋深处理中根系以平均1.24 cm·d-1的速率扎入地下水层外 ...

Effects of Fertilization Depth on Biological Character and Yield of Winter Wheat in Semi-arid Region

open access: yes, 2011
为给旱地作物合理施肥提供理论依据,以旱地小麦品种长武134为试验材料,采用隔离式上下两层土培装置,模拟黄土高原半干旱区"上干下湿"的土壤水分环境,研究了中度和重度水分胁迫下施肥深度对冬小麦生物学性状及产量的影响。结果表明,两种水分胁迫下施肥深度对冬小麦生物学性状、产量及其构成的影响不同。相同水分胁迫处理下,株高表现为上层施肥处理>下层施肥处理>未施肥处理;叶面积表现为下层施肥处理>上层施肥处理>未施肥处理;上、下层施肥处理间地上部生物量和籽粒产量差异不明显 ...
