连作晚季杂交水稻机械插秧用何种秧苗为适宜?机插后农艺性状与手插的有何差异?这是近年我国南方稻区急待研究的课题。二年来,我们针对上述问题在福州地区进行试验研究,采用盘式育秧法培育带土中、小苗供机插,初见成效:一九七九年四优二号用条播盘式育秧培育带土中苗适当早插的方法,由武夷75型机动插秧机机插,获得亩产1133斤,与同期手插分蘖秧的单产相近;一九八○年机插5亩,平均亩产847.3斤,其中1.37亩四优二号重复上年试验,仍取得亩产1012.4斤,四优光79用撒播盘式育秧育成带土小苗供日本井关PS650 Even for late hybrid rice mechanical seedlings with appropriate seedlings? Machine inserted after the agronomic traits and hand inserted What is the difference? This is the rice fields in southern China in recent years, an urgent task of research. In the past two years, we conducted experiments and research on the above issues in Fuzhou. Using the method of disc-type seedling cultivation, we planted seedlings in the soil and seedlings for planting. Initial results were achieved. In 1979, Miao suitable insertion method early, by Wuyi 75 mobile transplanter machine inserted, access to 1133 kg per mu, with the same period of hand-inserted tillering seedlings yield similar; machine inserted in 5 acres in 1980, the average yield of 847.3 kg per mu, Of which 1.37 mu Siyou No. 2 repeated the previous year’s test, still obtained 1012.4 kg per mu, Siu Guang 79 with spreading pan-type seedling nurturing with soil seedlings for Japan Jingguan PS650
