【摘要】 以桂淮2号、桂淮6号、GY44和南城药薯4个淮山药品种为材料,研究它们在不同栽培方式下农艺、产量等性状的表现,结果表明,桂淮2号和桂淮6号综合性状表现优良,在江西淮山药主产区具有广泛适应性和丰产性。搭架栽培产量比不搭架栽培极显著增加,但增收不显著。研究认为,桂淮2号和桂淮6号在江西生态条件下具有较好的推广应用价值,同时,应针对不同品种选择适宜的栽培技术才能发挥其经济价值。更多还原

【Abstract】 In this paper,the performances of the agronomic and yield characters of 4 Chinese yam varieties(Guihuai No.2,Guihuai No.6,GY44 and Nancheng medicinal yam) cultivated by different modes were studied.The results indicated that Guihuai No.2 and Guihuai No.6 had better comprehensive performances,and they had wide adaptability and high-yielding ability in the main Chinese yam producing districts in Jiangxi province.The yield of rack-building cultivation was significantly higher than that of no rack-building cultivation,but the income had no remarkable difference between two cultivation modes.The results deemed that Guihuai No.2 and Guihuai No.6 had good value of extension and application under Jiangxi provincial ecological condition.In order to express their economic value,suitable cultivation technologies should be chosen for different varieties.更多还原
