麒麟区机插秧软盘育苗试验研究

Experimental Study on Machine Seedling Planting Floppy Disk

试验分别设置不同播种量、种子消毒药剂浸种时间、覆盖物厚度、追施肥料品种、尿素不同追肥用量及营养土肥料配比等6个因子,开展机插秧软盘育秧试验。通过试验调查结果说明,在麒麟区蔬菜大棚内进行机插秧软盘育秧,最佳技术组合为：每盘播种量100 g;采用咪鲜胺2 000倍液浸种48 h;覆盖物厚度0.5 cm;采用当地旱地红壤土装盘,可均匀混入蔬菜复合肥（氮∶磷∶钾=17∶17∶17）3.6~7.2 g/盘,提高秧苗素质;追肥最佳肥料品种为硝酸铵2.4 g/盘·次。

This test set up 6 factors of different sowing rates, seed disinfection medicament seed soaking time, the thickness of the cover, topdressing fertilizer varieties, different urea fertilizer consumption and nutritional soil fertilizer ratio to carry out the machine planting floppy disk boards for testing. Through the experimental investigation results, it showed that the best technology combination is 100g per tray seeding rate, use the prochloraz 2 000 times liquid seed soaking 48 h, mulch thickness of 0.5 cm. Using local upland red loam plate, can be evenly mixed with vegetables compound fertilizer（N ： p ： k = 17 ： 17 ： 17）3.6～7.2 g/plate to improve the quality, best fertilizer fertilizer varieties for ammonium nitrate is 2.4 g/plate.
