摘要
在干旱条件下，所有经土壤保水剂Ｉｇｅｔａ－ＧｒｅｅｎＰ和Ｉｇｅｔａ－ＧｒｅｅｎＦＳ处理土壤种植的星星草，其幼苗生长状况均接近或超过无盐碱仅干焊处理植株，经土壤保水剂处理植株的脯氨酸含量均高于无盐碱仅干旱处理植株，因此本文认为施用土壤保水剂Ｉｇｅｔａ－ＧｒｅｅｎＰ和Ｉｇｅｔａ－ＧｒｅｅｎＦＳ对星星草幼苗具有提高其抗碱性的作用。
The state of growth of all the seedlings of Puccinellia tenuiflora showed in the soil treatalwith water--holding agent Igeta --GreenP and Igeta--Green FS and different concentrations ofNa2CO3 in the drought condition is bethe than that of the plants had not treatal with Na2CO3,the proline content of plants growing in the soil with the water hoaring agent and differentconcentrations of Na2CO3 treated is a lot higher that that of normally growing in the soil onlywith the water holding agent treated. Thus, we suggested that water--holding agent can helpthe seedlings of P. tenuiflora increase their alkaline resistance to some extent.
