我所甘薯高产栽培技术的研究,自一九七三年亩产突破万斤以来,连续进行了八年;其中六年亩产万斤以上,二年亩产八千斤以上。一九七六年产量最高,亩产15031斤。此项科研成果在基点示范推广也获显著的效果。一九七八年十二月经《中国甘薯栽培学》编写组实地考察验收:我所甘薯高产田,亩产达13410斤;示范基点石西大队,亩产达13049斤;渚林大队,亩产达1356斤。现将一九七三至一九八○年万斤甘薯群体结构及栽培技术的研究结果整理如下:
The research on sweet potato high-yielding cultivation techniques has been carried out for eight consecutive years since it broke through 10000 kg of mu production in 1973; of which, six-year mu production was over 10,000 kg and mu production was over 8,000 kg for two years. The highest output in 1976, 15031 pounds per mu. The achievements of this research have also been significantly promoted in the demonstration and promotion of the basic points. In December 1978, the compilation team of “China sweet potato cultivation” field inspection and acceptance: I sweet potato high yield field, yield 13,410 pounds; demonstration base point of the West Brigade, per mu up to 13049 pounds; Houzhu Brigade, mu Up to 1356 pounds. The results of the study on the structure and cultivation techniques of ten thousand kg sweet potato in 1973 to 1980 are summarized as follows:
