1981年在本所进行春播大豆引种试验。供试品种(品系)47个,以当地推广品种晋豆1号为对照。采用间比排列法,小区长15尺,宽9尺,6行区。试验地为粉砂壤土,肥力中等。为探讨山西中部春播大豆亩产400斤以上品种的产量构成和形态特征,选择产量不同的28个品种(品系)进行了分析,其中亩产404—476斤的9个,300—369斤的16个,276—290斤的3个。一、高产品种的产量构成在一定密度下,产量=单株成荚数×每荚粒×数单粒重,或产量=单株成粒数×单
Spring in 1981 in the introduction of soybeans test. Test varieties (lines) 47, to promote the local varieties Jin Dou 1 as a control. Using the ratio of arrangement, the district is 15 feet long, 9 feet wide, 6-line area. Test for silty loam soil, medium fertility. In order to investigate the yield components and morphological characteristics of more than 400 kg per mu yield of spring sown soybean in central Shanxi, 28 varieties (lines) with different yield were selected for analysis, of which 9 were 404-476 kg per mu and 300-369 kg per mu A, 276-290 pounds of 3. First, the yield of high-yield varieties in a certain density, yield = pods per plant x per pod × number of single grain weight, or yield = single grain number × single
