为了探讨花生良种“粤油551—116”的生长发育规律,为高产栽培技术进一步合理化提供理论依据,1980——1982年我们对该品种的生长发育全过程进行了系统的研究,现将3年的研究结果综述如下。研究方法供试品种为“粤油551—116”,分别于1980、1981、1982年春播,播种期分别在该年的2月25日、3月3日和2月24日。播种规格为8寸×3寸,单粒植,畦宽5.2尺(包沟)。基肥每亩施土杂肥2000斤,栽培技术措施按常规进行。齐苗后开始取样调查,1980年每隔7—10天取样1次,1981、1982年每隔7天取样1次,直至收获,全生育期共取样16—18次,每次取样20株。调查项目有主茎高、第一对分枝长、分枝亚枝数、主茎叶数、主茎青叶数、小叶长、宽度(主茎顶下第三片复叶)、叶绿素
In order to investigate the law of growth and development of peanut “Yueyou 551-116” and provide theoretical basis for further rationalization of high-yielding cultivation techniques, we systematically studied the whole process of growth and development of this variety from 1980 to 1982, The research results are summarized below. Study methods The tested varieties were “Yueyou 551-116”, which were sowed in spring in 1980, 1981 and 1982 respectively. The sowing dates were February 25, March 3 and February 24 of that year respectively. Sowing specifications for the 8-inch × 3 inch, single grain planting, width of 5.2 feet (including ditch). Base fertilizer per mu Shi Tu Hefei 2000 pounds, cultivation techniques and measures according to conventional. After Qi Miao began sampling survey, sampling once every 7-10 days in 1980, once in 1981 and 1982, sampling once every 7 days, until harvest, the whole growth period of sampling a total of 16-18 times, each sampling of 20 strains. The main survey items are the main stem height, the first branch length, the number of branch branches, the number of main stems and leaves, the number of main stems and leaves, the leaflet length and width (the main stem under the third compound leaf), chlorophyll
