金华地区早、中稻晚季栽培是在1958年试种早稻倒种春的基础上发展起来的。金华专区农科所、义乌良种场等单位从1959年起开始进行早、中稻作连作晚稻栽培的研究,同时全区各地也陆续开展试种示范。据不完全统计,目前已有陆财号、江南1224、矮脚南特、三九九、田基度、台北8号等不下50个早、中稻品种参加过试验试种,栽培面积1963年已扩大到2,000亩左右。从几年试验,特别是1963年的全区普遍示范来看,多数地区都获得良好结果,有的还取得了大面积平衡高产。如金华专区农科所23.58亩,平均亩产520斤;兰溪县宋宅公社宋宅大队31亩,平均亩产500
Jinhua early and mid-season rice cultivation in late-season cultivation of early rice in 1958 on the basis of the development of inverted spring. Since 1959, Jinhua Prefecture Agricultural Science Institute and Yiwu Variety Farm have carried out research on the cultivation of early and mid-season continuous cropping rice. At the same time, pilot demonstration projects have also been carried out in different districts throughout the region. According to incomplete statistics, no less than 50 early and middle-grade rice varieties have been tested and planted in southern China, such as Jiangnan 1224, Dantou Nantes, Sanjiujiu, Tiajiuji, and Taipei 8, and the cultivated area has been tested in 1963 Expand to about 2,000 acres. In the past several years of experiments, especially in the 1963 general demonstration in the region, most regions have achieved good results, while others have achieved large-area balance and high-yield. Such as Jinhua Prefecture Agricultural Science Institute 23.58 acres, an average of 520 pounds per mu; Songxi Song Lanxi County Song brigade brigade 31 acres, the average yield of 500
