| 摘 要： | 同一块地连作４ 年试验结果表明， 连作时间越长， 根产量越低， 连作第２ 年根产量下降１０ ．３ ％ ，含糖率下降２．２１ 度；连作３ 年根产量比第１ 年下降２０ ．８％ ，含糖下降４．４６ 度；连作４ 年根产量比第１年下降４７ ．８ ％ ，含糖率下降６．５０ 度。连作后地上部病虫害发生不严重，但根部病害严重，连作２ 、３ 、４年根腐病发病率分别为４ ．８％ 、１０ ．５％ 、１６ ．３ ％ 。连作时间越长块根个体长势越差

| Abstract: | Succession cropping about 4 yrs. and results have shown that, the yrs. have lasted, the rootyield were lower, the root yield decreased 10.3% and sugar content 2.21% decreased from 2nd succession cropping years. The root yield down 20.8% and sugar content down 4.46% which succession cropping 3id year when it compared with lst year and the 4th year,root yield down 47.8%, sugar content down 6.5%, after that leaf diseases have no more, but the root diseaes too seriously, the ratio of root diseases in the 2nd , 3rd, 4th year: 4.8%, 10.5%, 16.3% and root growth vigours poor with the time. |
