低频割制的高效性及其在生产上的应用

High Efficiency of Lower Frequency Tapping System and Its Application to the Production

目前提高割胶劳动生产率的途径有低频割胶、短线割胶、微割、针刺采胶、机械化采胶、管道流胶、尼龙袋收胶等等,但其中综合效果最佳的途径是低频割制。因为其它方法存在较大缺陷,有的造成减产,有的成本高,有的受环境制约,有的劳动强度太大等。当前,要提高我国低频割制的效能,就必须注意:①采用拖拉机运胶,减轻胶工的挑胶负担;②尽量采用大胶杯收胶,减少收胶次数;③采用S/2阴阳线轮换割制,少用S/4阴阳线同时割制,以简化割胶操作;④实行割胶和林管分开,或尽量采用机械化林管(化学除草和机械挖坑施肥);⑤加强当地天气预报,防止雨冲胶。

The present ways of increasing labor productivity of tapping include lower frequency tap ping,shorter-cut tapping,micro-cut tapping,penetrating ex ploitation,mechanized ex ploitation,collecting latex through pipes,collecting latex by nylon bags.The most effective way is lower frequency tapping,as other ways may cause production decrease or need high cost or be re strained by environment or require great labour intensity.In order to in crease the effi ciency of lower frequency tapping in China,attention must be paid to the following:①Carry latex by tractor to relieve the labour in ten sity of tapping workers.②Try to collect latex by bigger cup to reduce collecting times.③Adopt the one-half cut rotation up ward and downward tapping system,avoiding using the one-fourth upward and downward simul ta neous tap ping system in order to simplify the tapping operation.④Separate tapping work from manage ment of rub ber planta tions or try to use mechanical weeding and fertil izer ap plication.⑤Improve local weather fore cast to prevent rain from wash away the latex.
