河北省涿鹿县温泉屯公社吉家营大队是一个葡萄老产区。近年来,由于树势衰弱,产量低,连年死亡。第三生产队有45亩旱地龙眼葡萄,原定植每亩50—60株,到1972年只剩下每亩10株左右,平均亩产160斤。老贫农崔大仕总结了“连株压蔓”迅速丰产的经验,在45亩葡萄园里进行压蔓繁殖,增加株数,提高了产量。“连株压蔓”的具体方法是:春季葡萄出土后,把老蔓根部的土挖掉3—5寸深,使其露出根茎部(图1),疏松土壤,增高地温。随着葡萄发芽生长,从根茎 Zhuolu County, Hebei Province, Wenquan Tuen commune Ji Jiaying brigade is an old grape producing area. In recent years, due to the weakness of the tree, the output is low and has been declining year after year. The third production team has 45 acres of dry land longan grapes, the original planted 50-60 plants per acre, to 1972 only about 10 per mu, the average yield of 160 pounds. Cui Shi, an old poor peasant, summed up the experience of “rapid cropping” and quickly yielding herbage in 45 acres of vineyards, increasing the number of trees and increasing her output. The specific method of “even strain creeping” is: after the spring grapes were excavated, dig the soil of the root of the old vine 3-5 inches deep to expose the rhizome (Figure 1), loosen the soil and increase the ground temperature. As the grapes grow, grow from the rhizome
