摘要
杂交水稻经过20多年的种植,增产优势已被人们普遍认可。但由于受传统的栽培方式和种植观念的阻碍,没有真正发挥其高产优势。为了更好地利用杂种优势提高农作物产量,给扩大种植杂交水稻地区提供科学依据,海南省琼中气象局进行了大面积杂交早稻高产气象对策的推广试验,取得了成功。
After cultivation for more than 20 years, the production advantages of hybrid rice have been widely recognized. However, due to the obstruction from manners and concepts of traditional cultivation, their advantages of high-yield do not really play a role, in order to make use of the heterosis better to increase crop yield, in order to provide a scientific basisfor expanding the area of hybrid rice euhivation , we conducted a large area of experiment to promote yield of hybrid rice, which Had been successful.
