1986～1987年度,我们在本县漆桥乡舟村设省油菜“丰收杯”竞赛百亩丰产方的试验研究,取得亩产219公斤的高产成绩夺魁。该村地处茅山丘陵南缘,属北亚热带南部季风气候区。丰产方面积121.3亩,为紫色土质。其中冲田88.5亩,傍岗田32.8亩;中籼稻茬口94.2亩,后季稻茬口27.1亩。供试品种以宁油7号为主,搭配宁7-8和华油8号。本文就丰产方技术资料和辅助试验资料对油菜高产形成规律与栽培技术予以总结。 产量形成与高产途径 据丰产方产量构成因素与亩产量通径分析结果(表1)表明,在亩产155.4～283.5公斤范围内,亩有效角果数对产量的作用最大,角粒数次之,千粒
From 1986 to 1987, we set up a pilot study on the yield-saving and high-yielding side of rapeseed harvest harvest cup in Zhous Village, Qiuxiao Township of this county, and won the high yield of 219 kg per mu. The village is located in the southern margin of Maoshan hills, belongs to the northern subtropical monsoon climate zone. 121.3 acres of high yield area, purple soil. Including 88.5 acres of red fields, 3242 acres of coal fields near the postponed; Middle indica rice crop 94.2 acres, 27.1 acres of rice crop after the season. Test varieties to Ningyou 7, with Ning 7-8 and China Oil 8. This article summarizes the law of formation and cultivation of high yield of rapeseed on the technical data of high yield side and auxiliary test data. Yield formation and high-yielding ways According to the results of yield component of high-yielding side and per-acre yield analysis (Table 1), it shows that in the range of 155.4 ~ 283.5 kg per acre, the effect of acreage per acre is the greatest on yield, Thousand grain
