- 摘要:
- 为了给翠菊幼苗生长发育提供合理的施肥量,以硫酸钾为钾源,采用单因素随机区组试验设计,研究了钾素对翠菊幼苗生长的影响。结果表明:当硫酸钾用量为13.14~15.33 g.m-3时,对于翠菊幼苗的生长有促进作用,翠菊幼苗的株高(8.50和8.90 cm)和茎粗(3.82和3.88 mm)分别达到最大值。硫酸钾用量为13.14 g.m-3时,幼苗的全株干重(1 082.17 mg)、叶面积(9.81 cm2)及壮苗指数(2.10)均达到最大。硫酸钾用量为15.33 g.m-3时,翠菊幼苗的地上干重达到最大(460.68 mg)。
- Abstract:
- In order to provide the reasonable fertilizing amount for seedling growth and development of Callistephus chinensis(L.)Nees,taking potassium sulphate as potassium fertilizer,using single-factor randomized block experimental design,the effects of potassium fertilizer on the seedling growth and development of Callistephus chinensis(L.)Nees were studied.The results showed that potassium sulphate could improve seedling growth and development,when the amount was the 13.14~15.33 g.m-3,plant height 8.50 and 8.90 cm and stem diameter 3.82 and 3.88 mm,reached the maximum.when the potassium sulphate amount was 13.14 g.m-3,whole plant dry weight,leaf area and sound seedling index reached the maximum by 1 082.17 mg,9.18 cm2 and 2.10 respectively;when the potassium sulphate amount was 15.33 g.m-3,dry weight overground reached the maximum by 460.68 mg.
