我省有高产小麦田2000万亩,占小麦面积1/3。几年来,亩产一直在350～400公斤之间徘徊。人们在问:高产小麦还能增产吗? 山东农业大学小麦专家余松烈教授从70年代就开始探索,终于找到“大肥、大水、少播量”的增产栽培技术,就是将亩播量由过去的7.5～15公斤减少到5公斤以下,甚至2公斤,增大行距和粒距。这种栽培方法,在地力较高,肥水条件良好的土地上,较好地处理了群体发育与个体发育的矛盾,使小麦群体较
The province has a high yield of 20 million mu of wheat, accounting for one third of the area of wheat. Over the past few years, mu production has been hovering between 350 to 400 kg. People are asking: Can high-yield wheat increase it? Prof. Yu Songlie, a wheat expert from Shandong Agricultural University, started to explore from the 1970s and finally found the yield-increasing cultivation technology of “big fat, big water and less sowing” From the previous 7.5 to 15 kg reduced to 5 kg or less, or even 2 kg, increasing row spacing and grain distance. This cultivation method, in the land with higher fertility and good fertilizer and water conditions, better handled the contradiction between population development and individual development, making the wheat population more
