缩短胶树大田非生产期的有效措施之一,是用有孔的黑色聚乙烯袋培育大苗作定植材料。然而,由于许多农业因子的限制,至今用聚乙烯袋培育胶苗虽已有约十年的历史,但并未普及,过去只小规模地用聚乙烯袋培育在移植前约两个月截干的小苗芽接桩。根据最近的研究,采用适当的农业措施,可在苗圃用聚乙烯袋培育成大苗(6—7蓬叶),然后定植。研究结果表明,只要所用的土壤和袋的大小适当以及施肥充足,袋育苗长到与芽接约10个月的常规大田芽接苗相同的大 One of the effective measures to shorten the non-productive period of the gum tree field is to cultivate the seedlings for colonization by perforated black polyethylene bags. However, due to many agricultural constraints, the plastic bags so far made in polyethylene bags have been around for ten years, but have not been widely used. In the past, only polyethylene bags were used for small-scale cultivation about two months prior to transplantation The sprout pick then pile. According to recent research, suitable agricultural practices can be used to grow seedlings (6-7 Puffs) in polyethylene bags at nurseries and then colonized. The results show that bagging grows to the same size as a conventional field sprouted seedling that has been sprouted for about 10 months, provided the soil and bag sizes used are adequate and well-fertilized
