保水剂对夏花生种子萌发和植株生长的影响

通过田间试验,研究了保水剂对夏花生生长和产量的影响。结果表明,在干旱半干旱土壤上,应用保水剂对种子包衣处理能明显改善土壤供水状况,促进种子萌发和出苗,出苗期提前2d;应用保水剂的处理均能提高植株的抗旱性,促进夏花生的营养生长和生殖生长,使花生的分枝数和侧枝长分别比对照增加6.54%~6.90%和8.56%~10.65%,产量提高5.35%~28.75%。

Effect of Water Absorbent Polymer on Seed Germination and Growth of Summer Peanut

Effects of water absorbent polymer on growth and yield of summer peanut Luhua no.9 was studied under field experiments.The results showed that water absorbent applied in arid or semi-arid soil not only improved evidently the water supply,promoted seed germination,but also increased the durability to drought and benefited the plant to grow nutritionally or generatively.Compared with the control,the treatments showed a reduction of 2 days in bourgeoning time and increments of 6.54%-6.90% in the branch number,8.56%-10.65% in the lateral root length and 5.35%-28.75% in the yield,respectively.
