摘要
对葛根的移栽时间、移栽苗的大小、施肥标准、种植密度、种植方式和高产葛园各个不同生长阶段的长相标准进行了规范化栽培研究。结果表明:湘葛一号产量比一般的品种高一倍以上。以直径约为2 cm大苗为移栽苗,并在4月底前移栽产量最高。以施硫酸钾复合肥1 125 kg/hm2、人畜粪22 500 kg/hm2、土杂肥112 500 kg/hm2能获高产。搭架栽培其产量明显比不搭架的高,搭架栽培密度以12 000～15 000株/hm2为宜。按照上述方法栽培,当年产量能达到3万kg/hm2左右。
A standardized cultivation research was conducted to the transplanting time,the size of transplant seedling,fertilizer standard,planting density and planting method of Radix Puerariae and the appearance standard of Radix Puerariae in each growing stage of high-yield Radix Puerariae orchard.The results showed that the yield of Xiangge No.1 is over one time higher than the others general varieties,and the yield is the highest when taking big seedlings with diameter of 2 cm as transplanting seedlings and transplanting it before end of April;it could be high-yield when applying potassium sulfate compound fertilizer of 1 125 kg/hm2,animal and human manure of 22 500 kg/hm2 and miscellaneous fertilizer of 112 500 kg/hm2;the yield of shelf cultivation is obviously higher than that of non-shelf cultivation,and the optimum density of shelf cultivation is between 12 000 to 15 000 shoots/hm2.If cultivating the Radix Puerariae by using the above method,the annual yield could reach around 30 000 kg/hm2.
