我省大豆面积大,近年来大豆始终徘徊在亩产90——100公斤的水平。1992年10月7—9日笔者在灵壁县韦集镇双龙村,为期3天,考察了该地大面积丰产的现场,得到了很大的启发。1315.5亩夏大豆目前已收获脱粒完毕,经风干扬净逐户统计共获实产236640公斤。平均亩产达179.9公斤。其中亩产在80—125公斤范围占119亩;亩产在126—175公斤范围占508亩;亩产在176—225公斤范围占509亩;亩产在226—275公斤范围占154.5亩;亩产在276—300公斤范围占25亩。亩产276公斤以上的产量均是在油菜茬的田块获得的。由于该村推行丰产栽培是第一年,少数农户因施肥不当引起疯长,或瘦田稀播,或缺苗断垄,导致产量不高。1993年在栽培技术上,只要严要求高标准,单产尚可进一步提高。
Soybean area in our province is large, in recent years, soybean has been hovering at the level of 90--100 kg per mu. October 7-9, 1992 I was in Lingwei County, Weiji Town, Ssangyong Village, for a period of 3 days, inspected the site of large areas of high yield, has been greatly inspired. 1315.5 acres of summer soybean has now been harvested threshing completed by air-dried Yang net household statistics a total of 236640 kilograms. The average yield of 179.9 kilograms. Among them, the area of mu produce accounts for 119 mu in the range of 80-125 kilograms; the per mu yields 508 mu in the range of 126-175 kilograms; the mu produce accounts for 509 mu in the range of 176-225 kilos; the mu produce 154.5 mu in the range of 226-275 kilos; Production in the 276-300 kilograms of 25 acres. Yields of more than 276 kg per mu were obtained from fields of rapeseed stubble. As the first year of high-yielding cultivation in this village, a small number of farmers are soaring due to improper fertilization or thin sowing or scarce seedling, resulting in low yields. In cultivation technology in 1993, as long as the strict requirements of high standards, yields can be further improved.
