摘要
使用杂交稻品种“汕优63”在安宁河流域干热河谷稻区的云甸乡实施水稻高产攻关试验。栽培措施上采取两段育秧培育壮秧,确定适宜基本苗,宽窄行栽插合理密植,控制最高苗;施肥方式方法上磷肥与农家肥堆沤作底肥,氮肥“重底早追,前促中控后补”,钾肥在水稻生育中期重施,合理配方N:P:K为2．5:1:1．5,补施微量元素硅肥。经验收,产量达13612．5 kg／hm2。
By using hybrid rice “Shanyou 63” to have a brainstorm experiment on rice high production at Yundian in An＇ ning river warm valley, we take two steps to breed seedling on breeding measures, choose suitable basic seedling, plant reasonably at space and control the highest seedling. On supplying manure, we use phosphate fertihzer and farmhouse＇s manure as base manure, supply nitrogenous fertilizer at different time, and supply potash fertilizer again during the middle period of rice growing with suitable formula 2.5（N）：1 （P）：1.5（K）, and then supply microelement silicon fertilizer. After checking, the yield is up to 13612.5 kg / hm^2.
