摘要
小麦生产对我国粮食安全十分重要,品种改良是最主要的科技因素。面对种植面积下降、水资源短缺、化肥利用效率低等问题,小麦品种改良的对策是培育节水、省肥、高产的超级小麦新品种,通过合理的品种推广方式,良种良法结合,实现大面积高产高效。
The variety improvement is the most significant scientific and technologic factor in wheat production, which is very important to the food security of China. Facing the problems of reducing sowing area, water resources shortage and lower use rate of fertilizer, the objective of wheat improvement is the super-wheat cultivar by the strategy of breeding water saving, economizing fertilization and high-yielded characters. Through the reasonable variety extensive way, integrate improved variety and good cultivation techniques, the high output and efficiency in a large area can be realized.
