本项研究在我校(偃师县)试验地进行。目的是,试从小麦的个体长相着手,运用统计方法,分析和探讨高肥水条件下小麦高产的群体指标并比较不同种植方式的增产效益。一、试验方法个体资料取材于小麦原始材料圃。分别在灌浆和收获期取样测定,统计分析;群体指标测定的主要供试品种是72—1104(矮车三号选系),株高70厘米左右,株型紧凑,分蘖力强,属于大穗多花类型。种植方式和基本情况列于表一。三叶后,每隔五天或十天(越冬期)调查一次,结合定株观察选取十株或二十个单茎(孕穗后)进行单株分析;收获时选五十株进行室内考种。
This study was conducted in our school (Yanshi County). The purpose is to start with the individual appearance of wheat and to use statistical methods to analyze and discuss the group of high-yielding wheat populations under high water-cut conditions and compare the yield-increasing benefits of different planting modes. First, the test method Individual data drawn from the wheat raw material nursery. The main test varieties were 72-1104 (Dashu 3), with a height of about 70 cm, compact plant type and strong tillering ability, belonging to the big spike Multi-flower type. The planting methods and the basic situation are listed in Table 1. After three leaves, every five days or ten days (overwintering period) survey, combined with the observation of plants selected ten or twenty single stem (after booting) for single plant analysis; harvest selected 50 plants for indoor test .
