苏薯2号是江苏省农科院“七五”期间育成的高产高淀粉甘薯新品种,目前正在省内外甘薯生产区大面积推广种植.为进一步完善良种良法配套的高产栽培技术措施,我们在过去单因子试验基础上,于1991年进行了NPK不同组合水平的复因子试验,研究NPK不同施肥水平与产量结构因素的关系及其数学模型,为甘薯高产栽培提供科学依据.
Jiangsu Shuhua No. 2 is a high-yield and high-starch sweet potato variety bred during the “Seventh Five-year Plan” period of Jiangsu Academy of Agricultural Sciences and is being popularized in a large area in sweet potato production areas both inside and outside the province. In order to further improve the high- Based on the single-factor experiments in the past, complex factor experiments of NPK at different combinations were conducted in 1991 to study the relationship between NPK fertilization levels and yield structure factors and their mathematical models to provide a scientific basis for high-yield sweet potato cultivation.
