摘要
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/hm^2),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 trans-planting 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 (2.69×10^5 hills/hm^2), and nitrogen fertilizer applying of basal, tillering, panicle as 5∶4∶1 or 4∶5∶1.
