土壤保水剂对星星草幼苗抗旱性的影响

THE PROMOTIVE EFFECTS OF WATERHOLDING AGENT ON DROUGHT RESISTANCE INSEEDLINGS OF PUCCINELLIA TENUIFLORA

在干旱条件下,所有经土壤保水剂 Igeta—Green P 和 Igeta—Green FS 处理土壤种植的星星草,其幼苗生长状况均超过干旱处理植株,经土壤保水剂处理植株的脯氨酸含量远低于干旱处理植株,因此本文认为施用土壤保水剂 Igela—Green P 和 Igeta—Green FS 对星星草幼苗具有促进抗旱的作用。其中又以浓度为0.8%和1.0%的 FS 和 FS+P 效果最明显。

The state of growth of all the seedlings of Puccinellia tenuiflora showed in the soil treated with water-holding agent Igeta-Green P and Igeta-Green FS in the drought condition was better than that of the plants that had not supplied with soil water-holding agent.The proline content of plants growing in the soil treated with the water-holding agent was much lower than that of normally growing plants in the drought condition.Thus,we suggested that both the Igeta-Green P and Igeta-Green FS can help the seedlings of P.tenuiflora increase their drought resistance, and 0.80% and 1.00% FS or FS+P is the concentration of water-holding agent which have the best effect.
