再生制种是利用头季制种田收割后父母本稻桩上的休萌芽,通过肥水管理,促其再生成穗配制。它能充分利用两季不足而一季有余的光热资源,多收一季种子,投入少,经济效益高,很受农户欢迎。1990～1992连续3年,我们在赤门乡良种场制种基地,进行了杂交水稻再生制种技术探讨,取得了一定的成效。 1990年试验20亩,组合为汕优63。经有关单位领导和科技人员验收,头季制种亩产186.1kg,再生季制种亩产
Regeneration is the use of the first season after harvest farming parent piles on the seedlings of buds, fertilizer and water management, and promote the formation of spike regeneration. It can take full advantage of the lack of more than two quarters of the season of light and heat resources, more than a season of seeds, less investment, high economic efficiency, very welcomed by farmers. From 1990 to 1992, for three years in succession, we explored seed production techniques for hybrid rice in the seed production base of the improved seed field in Taimen Township and achieved some success. Test 20 acres in 1990, the combination of Shanyou 63. The relevant unit leaders and scientific and technological personnel acceptance, the first season of seed production 186.1kg, the regeneration season seed production
