摘要
为比较夏直播花生单粒播种与双粒播种在植株性状和产量构成因素、产量结果方面的差异,连续三年在大田条件下,采用麦后直播、起垄覆膜栽培技术,每年选用四个疏枝大果中熟品种和四种不同配置方式进行了研究.研究结果表明:四个品种连续3年均表现出共同趋势,即单粒播种与双粒播种相比,株高变矮0.13-3.57cm,第一对侧枝长度缩短0.07-3.45cm,单株总分枝数增加0.20-1.65条、结果枝数增加0.03-1.66条,有效枝长和结果范围内节数也有所增加;果重略增,单株果数和单株产量都显著增加,分别增加4.97%-34.53%和5.99%-37.87%,单位面积产量增加1.13%-11.53%.
Research was carried out on four selected varieties and four different configurations of direct-sowing after wheat and plastic film mulching cultivation technologies of peanut to study the differences of plant characteristics and yield components on single-seed and double-seed sowing for three years. Results showed that： compared with double-seed sowing, plant height of single-seed sowing peanuts shortened by 0.13 to 3.57cm, length of the first pair of lateral branches shortened by 0.07 to 3. 45cm, number of branches per plant increased by 0.20-1.65, number of fruiting branches increased by 0.03-1.66, fruit weight increased slightly, Yield and number of fruit per plant increased significantly. Number of fruits per plant and yield per plant increased by 4.97% to 34.53% and 5.99% to 37.87% respectively. Yield per unit aera increased by 1.13% to 11.53%.
