花生是沙苑地区的主要经济作物,约占耕地面积40％左右。为了总结高产经验,促进花生生产的发展,1981年我们组织79个科技户,开展花生高产栽培技术实验,秋季考察验收的有12块地19.9亩,亩产600～800斤,其中3块3.4亩,亩产达800斤以上,最高亩产855斤,现将实验资料总结如下: 一、产量构成因素花生荚果产量是由每亩株数、单株结果数和果重三因素构成。各高产田块选用品种为疏枝型、中熟、大果的“徐州68—4”,亩产600～800斤的产量构成因素指标是,每亩种植5000～6000窝,实收株数1.2～1.5万 Peanut is the major cash crop in the Shayuan area, accounting for about 40% of the cultivated area. In order to sum up high-yielding experience and promote the development of peanut production, in 1981 we organized 79 science and technology households to carry out high-yielding peanut cultivation experiments. In autumn, there are 12 plots of 19.9 mu and 600-800 kg per mu, of which 3 are 3.4 mu , Mu yield of 800 pounds or more, the highest yield of 855 pounds per mu, the experimental data are summarized as follows: First, the yield components of peanut pod production per mu of plants, the number of fruit trees and fruit weight of three factors. The selection of high-yield plots for the varieties of thinning, medium, large fruit “Xuzhou 68-4”, yield of 600 to 800 kg per mu yield indicators, planting 5000 ~ 6000 nest per mu, the actual number of plants 1.2 ~ 15,000
