为了摸索小麦高产的生育规律,掌握高产栽培的田间生态测报指标,我们从1979年开始,对本县两个骨干品种“7023” (半冬性)和襄麦5号(春性)进行了连续三年的定株观察。 一、观察方法 两品种每年每个播期各固定10株,年前每隔3天、年后每隔3—5天记载一次叶龄;每分一个蘖,就挂一个塑料牌,并记载分蘖出生日期和蘖位。收获时连根拔起,分别考种。1979—1980年度两品种各观察一个播期:即10月25日播的“7023”(亩产611斤),10月30日播的襄麦5号(亩产614斤)。
In order to explore the law of reproductive growth of high-yielding wheat and to master the ecological forecasting indicators for high-yielding cultivation, we conducted a series of experiments on two key cultivars “7023” (semi-winter) and “Xiangmai 5” (spring) Year of observation. First, the observation method Two varieties of each sowing each fixed 10 each year, every year before the three days, every 3-5 days after the year record leaf age; every tiller, hanging a plastic card, and records tillers Date of birth and tillering position. Uprooted when harvesting, respectively, test species. In 1979-1980, two varieties were observed for one sowing date: “7023” (611 kg per mu) sowed on October 25 and Xiangmai 5 (614 kg mu per mu) sowed on 30 October.
