| 摘 要： | 采用两个Ｌ９（３４）正交表安排黑麦草良种Ｇｏｒｄｏ、Ｌｉｐｏ、２１２、Ｌｉｍｅｌａ、Ａｕｂａｄｅ和Ｄｅｒｂｙ等６个的正交试验结果说明，因素的水平较佳处理组合、每００６７ｈｍ２的鲜草产量和选择丰产栽培品种的次序为：Ｇｏｒｄｏ的Ｂ３Ｃ３Ｄ３为１３４０６７，Ａｕｂａｄｅ的Ｂ２Ｃ３Ｄ１为１３２６９０，Ｌｉｍｅｌａ的Ｂ３Ｃ３Ｄ３为１２９８４５，Ｌｉｐｏ的Ｂ２Ｃ３Ｄ１为１２９７７８，２１２的Ｂ１Ｃ３Ｄ２为１１５４０１和Ｄｅｒｂｙ的Ｂ３Ｃ２Ｄ１为８０３５６ｋｇ，皆达到高产水平，３和２水平极显著或显著高于１水平的产草量。因此认为，黑麦草丰产栽培的关键技术有三，一是在标准用种量的基础上加大标准用种量的２５％～５０％作为实际播种量，以确保获得足够的基本苗；二是采取撒播下种；三是要较高施肥水平。

| Abstract: | When two L 9(3 4) orthogonal tables were arranged in use,six ryegrass cultivars in trial were Gordo,Lipo,212,Limella,Aubade and Derby respectively.The results showed that the excellent combination at factorial level order based on grass yield per 0 067hm 2 were as follows:B 3C 3D 3-cv.Gordo,yield-13406 7kg;B 2C 3D 1-cv.Aubade,yield 13269 0kg;B 3C 3D 3-cv.Limella,yield 12984 5kg;B 2C 3D 1-cv.Lipo,yield-12977 8kg;B 1C 3D 2-cv.212,yield-11540 1kg;and B 3C 2D 1-cv.Derby,8035 6kg,all attained the highest level.And meanwhile,the yields of fresh grass in level 3 and level 2 were shown significantly higher than that of leve1 l.On the basis of trial results,the conclusion was that there were 3 key techniques stressed on ryegrass cultivation:1)the seed yield was 25% ～50%higher than the seeding standard,which would insure enough seedlings;2)applying of broadcast sowing was necessary and 3)enough fertilizers should be used as required. |
