【摘要】 研究表明:广东小麦具有分蘖期短,成穗少,分蘖高峰期出现早,高峰持续时间长;幼穗分化早,分化期短,小花退化晚,退化集中;籽粒灌浆期长等特点。在广东的生态条件下,根据小麦上述特点对品种选用、增产途径、播种期、培育壮苗以及防止后期阴雨天气对籽粒灌浆等影响,趋利避害,以达到高产稳产,提出一些看法。更多还原

【Abstract】 It has been found in this experiment that the wheat in Guangtongprovince has the following characteristics:short tillering period,loweffective-tillering rate,early appearance of the tillering stage with alongpersisting peak,early differentiation of the spike and a short differentia-ting time,late concentrated degeneration of the floscule and a long grainmilking stage.Under the ecological conditions in Guangtong provincc,in accordancewith the above-mentioned characteristics of wheat,the authors have putforward some suggestions to avoid the harmful factors and make use ofthe advantages.In order to ensure a high,stable yield it is suggested toput emphasis on:cultivars to be chosen,the ways to increase production,sowing time,the cultivation of stout seedlings,and the prevention fromthe bad effects of the rainy days on grain milking in the late stage.更多还原
