近几年我们组织了西华、南乐、临颖、上蔡、郑州、邓县、临汝、延津、开封、新乡等科研单位及大队农科站协作,开展了红薯高产栽培技术研究.1978-1980年,全省29点次高产试验田38.84亩,鲜薯亩产7016-9672.8斤(小面积突破万斤),平均为8366.4斤,折薯干亩产1558.7～2650.7斤,平均为2120.9斤.现将红薯亩产八、九千斤的群体生长动态和长相指标初步综述如下:
In recent years, we organized scientific research units such as Xihua, Nanle, Linying, Shangcai, Zhengzhou, Dengxian, Linru, Yanjin, Kaifeng, Xinxiang and other agricultural research institutes to conduct research on high-yield sweet potato cultivation techniques. From 1978 to 1980, the province produced 38.84 mu of high yield 29 trial plots and 7016-9672.8 kilos of fresh potato per mu (a small area exceeded 10,000 kilos), with an average of 8366.4 kilos and an average of 2120.9 kilos At present, the dynamic growth and the appearance index of the group of eight to ninety kilograms of sweet potato per mu are summarized as follows:
