我场地处桂中偏北地区,历年在三月上中旬都受春寒威胁,大田尚不宜插秧,九月下旬末或十月上旬初必有寒露风的侵袭,影响晚造空秕粒多和结实不饱满等情况。一九七七年在英明领袖华主席“抓纲治国”,一年初见成效,三年大见成效的伟大号召指引下,我场进行大面积杂交水稻早晚连作栽培试验,早造战胜早春寒,22.65亩平均亩产1007.76斤;晚造避过寒露风,24.67亩平均亩产994斤。通过实践,获得了一些初步体会。 My field is located in the north-central Guangxi region, all over the calendar year in mid-March by the threat of cold spring field is not suitable for transplanting, in late September or early October there must be cold dew invasion, the impact of late-made empty noodles more grain and strong Not full and so on. In 2007, under the great call of Chairman Hua, who wisely led Chairman Hu Jintao and “rule the country by state”, achieved initial success in one year and achieved fruitful results in three years, we conducted a trial of morning and evening continuous cropping of large-area hybrid rice. , 22.65 mu average yield of 1007.76 kg per mu; late to avoid cold dew, 24.67 mu average yield 994 kg. Through practice, obtained some preliminary experience.
