自大跃进以来,我国小麦产量获得了巨大的增长,全国各地相继創造了高額丰产的卫星田,出現了我国史无前例的小麦亩产千斤以上的奇迹。然而部分地区只追求小面积高产指标,而忽视了大面积均衡增产,因此,这些地区常常存在有大面积的三类苗,使小麦总产量不能迅速提高。“麦收胎里富,見苗三分收”,这句农諺生动地說明培育小麦壮苗对于丰产具有极其重要的意 Since the Great Leap Forward, the output of wheat in our country has witnessed tremendous growth. Satellites of high yield and high yield have been successively created in all parts of the country. There has been a miracle that the output of wheat in our country has reached an unprecedented level. However, in some areas, only the small-area, high-yield index is pursued while the large-area and balanced production increase is neglected. Therefore, there are often three types of large-area seedlings in these areas, so that the total output of wheat can not be rapidly increased. “Wheat harvest in the rich, see seedlings three points,” this proverb vividly shows that cultivating strong seedlings of wheat is of great importance to the high yield
