勐腊分公司速生、高抗、高效二代胶园建设技术

勐腊橡胶分公司在植胶资源极为有限的条件下，为将二代胶园建设成速生、高抗、高效，集社会效益和经济效益为一体的生态环保型橡胶园。充分利用现有更新胶园的土地资源进行科学规划，采用宽行密株种植形式，合理密植、规范开垦，使土地资源利用率比更新前提高50.53%。并根据植胶小区环境，结合品种特性对口配置具有相应抗性的速生、高抗、高产优良品种，充分发挥地力和品种的潜力。积极推广应用高吸水树脂春季抗旱、节水、保肥、速生栽培技术，促进胶苗速生，可比新植胶园提前一年投产开割，增加经济效益480.73万元/年。

Establishment of Fast-growing, Highly Resistant, Effective, Second Generation Rubber Plantations

A scientific planning for the replanted rubber plantation land was made by Yunnan Natural Rubber Industry Co. Ltd. Mengla Branch to include planting patterns of wide row and dense population, rational dense planting, and standard land preparation. The land resource use rate was increased by 50.53%. Relatively stress-resistant, fast-growing, cold resistant, high yielding clones were arranged based on the microenvironment and clonal characteristics to make full use of the potential of the land and avail-able clones. A fast growing cultivation by using high water absorbent resin to combat drought, water con-servation, fertilizer management was recommended for practice to improve rapid growth of nursery plants. Rubber plantations managed by this cultivation practice were put into production (tapping) one year earlier than those newly planted, and increased economic benefits by 4.8073 million yuan/year.
