摘　　要：研究了优质杂交粳稻MH2 0 0 3、寒优湘晴的有机栽培技术。结果表明 ,该二组合分蘖高峰期在 7月 2 5～ 30日 ,高峰苗数在 2 95 .5～ 36 0 .0万 hm2 之间 ,产量分别达 6 5 16kg hm2 和70 15 .2kg hm2 ;采用中草药驱避剂预防虫害、硅化物L提高肥效和增强植株抵抗力、大田水育秧缩短本田期等栽培技术措施取得了较好的效果。Organic cultivation techniques on hybrid japonica rice 'MH2003' and 'Hanyouxiangqing' were studied. The peak tillering stage of the two varieties were during July 25th to 30th, their peak tiller numbers were between 295.5×10 4/hm 2 and 360×10 4/hm 2, and their yields were 6516kg/ hm 2 and 7015.2kg/ hm 2, respectively. Insectifuge made from Chinese medicinal herbs was used to control insect and pest, silicide L was used to improve fertilizer efficiency and enhance rice plant resistance,and water breeding seedlings were used to shorten growing duration. All the cultivation measurements above proved to be effective.
