密植无杆速成高产茶园试验包括四个课题:一是茶树适当密植,二是茶树地上部无主杆,三是茶树快速成蓬开采,四是提高茶园亩产。我们于1973年在河铺公社王家道大队桑茶场开始试验,1975年又在溢流河公社华三大队茶场重复试验,先后经过四年,两个试点都初步取得显著成效。王家道桑茶场试验茶园1976年亩产干茶577斤,比对照亩产174斤增产两倍多;华三茶场亩产干茶由 Close-planting non-stick speed into high-yield tea garden test includes four topics: First, appropriate close planting tea, the second is no pole in the upper part of the tea tree, the third is the rapid development of tea into a canopy, the fourth is to improve tea yield per mu. In 1973, we started the trial at Sang Chachang, a unit of Wangji Road, Hepu Commune. In 1975, we repeated the trial at the tea plantation of the Wusan Brigade in the overflow river commune. After four years in succession, we achieved notable initial success in both pilot projects. Wang Road, Sang Chachang test tea plantation in 1976 acres of dry tea 577 kg, 174 kg more than the control yield more than twice as much;
