种植优质高产低耗的苎麻,既是广大麻农的愿望,也是麻纺工业的要求,如何实现?除了品种的差异,还取决于栽培的技术。从1985—1987年我们进行了品种、密度、肥料三方面的五因子四水平正交试验,以探讨苎麻优质高产的有关技术和栽培模式,现将三年试验结果报告如下:1 材料与方法试验选用 L_(16)(4)~5正交表设计,五个因子分别为品种、密度、氮、磷、钾肥的用量,每个因子各设有四个水平(表1)。各品种全用细切种根材料种植,新余麻、青壳子、野麻为江西地方品种,并经过
To grow ramie with high yield, high quality and low consumption is not only the wish of the majority of hemp farmers, but also the requirement of the hemp spinning industry. How to realize it? Besides the difference of varieties, it depends on the cultivation techniques. From 1985 to 1987, we carried out orthogonal test of five factors and four levels in three aspects of variety, density and fertilizer to explore the related technology and cultivation mode of high quality and high yield ramie. The results of three years test are as follows: 1 Materials and Methods The design of L_ (16) (4) ~ 5 orthogonal table design, the five factors were the variety, density, nitrogen, phosphorus and potassium consumption, each factor has four levels (Table 1). All varieties of fine cut with all kinds of planting materials, Xinyu Ma, green shell, wild hemp Jiangxi local varieties, and after
