滦县第四农业技术推广站花生压蔓是苏联的增产经验,近两年来河北省很多地区都在重点试验或普遍推广,但结果表现极不一致,有增产的也有减产的,而且减产较增产多。现就我们调查的情况及对比田的结果,初步分析以下几点,供参考。压蔓与稀密度稀植花生压蔓后表现增产。如滦县兴隆庄富强农业社的七块对比田,行距为1.55-1.6尺,墩距1.0-1.2尺,每亩密度为3,100-3,800墩,结果压蔓比不压蔓的平均增产8.4%。密植花生压蔓后表现减产。如
Luanxian Fourth Agricultural Technology Extension Station peanut grazing is the Soviet Union’s yield-increasing experience in recent years, many areas in Hebei Province are focused on testing or universal promotion, but the results were extremely inconsistent, there are also increased yield reduction, and reduce production more than increase. Now we investigate the situation and compare the results of Tian, a preliminary analysis of the following points for reference. Volatile vine and sparse density of peanut after the performance of vine yield. Such as Luanxian prosperous Zhuang strong agricultural cooperatives of seven fields, spacing of 1.55-1.6 feet, pier spacing of 1.0-1.2 feet per mu density of 3,100-3,800 piers, the results of the creeping than the average vine yield 8.4%. Close planting peanut performance after the reduction of output. Such as
