通过对机插早籼稻品种、播期、播种量、秧龄、栽插密度和施氮方式等关键技术试验研究,提出了浙江苍南机插早稻高产配套栽培技术,即在选择中嘉早17、中早39、嘉育253等高产中熟品种的基础上,3月25至4月1日播种,播种量150~175 g/盘,秧龄控制在20 d左右,机插规格30.0 cm×12.4 cm(26.9万丛/hm2),施氮方式为基肥∶分蘖肥∶穗肥为5∶4∶1或4∶5∶1。
Suitable variety, sowing date, sowing rate, seedling age,planting density and nitrogen application methods of machine transplanting conventional early indica rice were studied in the paper. The suitable cultivation techniques are summarized as follows: choosing high yield and middle maturity varieties such as Zhongjiazao 17, Zhongzao 39, Jiayu 253, sowing seed during March 25th to April 1st with the sowing rate 150~175 g per seeding tray, controlling the seedling age about 20 days in density of 30.0 cm×12.4 cm(2.69×105 hills /hm2), and nitrogen fertilizer applying of basal, tillering, panicle as 5∶4∶1 or 4∶5∶1.
