吸水树脂抗旱保肥提早橡胶幼苗定植试验研究

Study on Utilization of Water Absorbing Resin for Drought Resistance, Fertilizer Preservation and Early Establishment of Rubber Seedlings

为充分利用景洪３～５月的光、热资源，在植胶区利用吸水树脂进行橡胶幼苗抗旱栽培，使橡胶芽接桩定植期提早到３月下旬进行，可确保成活率达９８％以上。按照常规管理，年底可长到６蓬叶以上，比雨季开始后定植的多长２～３蓬叶，使橡胶非生产期缩短，从而达到提早割胶的目的。

By using water absorbing resin in rubber cultivation in Jinghong, Yunnan Province for drought resistance, fertilizer preservation and early establishment of rubber seedlings, the planting date of rubber seedlings was shifted to the last 10 days of March. The survival rate of rubber seedlings reached 98%. More than 6 leaves could be grown at the end of the year by employing traditional management method, thus the non productive period was shortened and reached rubber tapping early.
