比较了围洞法(定植后不再淋水)、围洞法+30~60g/株保水剂(定植后不再淋水)、80g/株保水剂(定植后不再淋水)、常规抗旱定植方法(定植后定期淋水)进行橡胶裸根芽接桩苗抗旱定植的效果。结果表明,定植40d后,采用围洞法+30~45g/株保水剂的处理,植穴内土壤含水量较高,裸根芽接桩苗定植成活率高,新植胶苗早期生长快,效果优于围洞法处理、极显著优于80g/株保水剂和常规抗旱定植的处理。
Comparison of the surrounding hole method (after the planting no longer water), the hole method + 30 ~ 60g / strain of water retention agent (no longer after the planting of water), 80g / strain of water retention agent (no watering after planting), conventional drought Colonization method (regular watering after planting) for rubber bare root sprouting seedling planting drought resistance effect. The results showed that after 40 days of colonization, the soil moisture content of planting hole was higher than that of the water-retaining agent of 30-45g / hole, and the survival rate of bare-rooted bud pile planting was high. It was significantly better than that of 80g / strain SAP and conventional drought-resistant colonization treatment.
