高垅栽薯法,在修水县山口区试验推广五年了。过去,我区采用平畦栽薯法,虽然亩栽六、七千蔸,但因耕作层浅薄,施肥不集中,造成个体发育差,后期群体结构不协调,结果产量不高。在吸取外地红薯堆栽法经验的基础上,经过几年的试验摸索,我们得出了“高垅栽著法”,即将小垅加大加高,垅底宽2.4尺,顶宽1.6尺,沟深1.6尺,每亩比平畦少栽一半藤,兼顾个体与群体。1975年在桃坪公社中兴九队试验,每亩增产85％。次年,扩大到山口、复源两公社,面积近三百亩,在夏秋连续干旱80多天 Gaotian planting potato method, test in Xiukou County, Yamaguchi Prefecture promotion of five years. In the past, our district adopted the planted flat-bottomed potato method. Although six-thousand and seventy-thousandth acres were planted, due to the shallow cultivation layer and poor fertilization, the individual development was poor and the post-colonial population structure was uncoordinated. As a result, the yield was not high. Drawing on the experience of field cultivation of sweet potato heap, after several years of trial and error, we come to the “method of cultivation of high tuna”, about to step up the small tuna, bottom width of 2.4 feet, top width of 1.6 feet, Groove 1.6 feet deep, less than half planted per acre vine Ping, take into account the individual and groups. In 1975, the trial of Peking Zhongxing nine teams, an increase of 85% per mu. The following year, expanding to Yamaguchi, Fuyuan two communes, an area of ​​nearly three hundred acres, drought in summer and autumn more than 80 days
