橡胶树更新,在倒树前如何最大限度地多拿产量,是广大植胶者最关心的问题。1983年,海南农垦局生产处在国营东太农场250.3亩当年将更新倒树的橡胶树上进行了强割试验,取得了显著的效果。平均亩产干胶由强割前的26.2公斤提高到51.8公斤,增产了97.7％,株产由强割前的1.31公斤提高到2.62公斤,增产了一倍。总产干胶12 965公斤,比强割前的6,550公斤增加了6,415公斤,经济纯收益达24,345元,平均每亩增加收益67.3元,每株3.397元。他们的做法是: 一、合理安排割线。(1)每株胶树开占割线二分之一树围的割线4条,即两个割面
Rubber tree update, how to maximize the amount of yield before the tree is inverted, is the majority of the majority of plasticizers are most concerned about. In 1983, Hainan Bureau of Reclamation production in the state-owned farm on the East Pacific 250.3 acres will be updated in the year to reverse the tree rubber tree cut test, and achieved remarkable results. The average yield per mu of glue from the strong cut before the 26.2 kg to 51.8 kg, an increase of 97.7%, strain from strong cut before the 1.31 kg to 2.62 kg, doubling the production. The total output of dry glue was 12,965 kilograms, an increase of 6,415 kilograms over 6,550 kilograms before strong cutting. The net economic income reached 24,345 yuan, with an average increase of 67.3 yuan per mu and 3.397 yuan per plant. Their approach is: First, reasonable arrangements cut line.
