为了探讨小麦边际效应的增产潜力,我校农业组与周围大队试验站结合,于1975年秋播时,设计了测定留空带1尺的边际效应试验方案:即小麦行距5寸,每种11行留1尺空带,并把紧挨空带的1行称边行,紧挨边行的称次边行,次边行内的7行系内行。在植物生长和收获期间对小麦的性状和产量进行调查和测定(见表1)。
In order to explore the yield potential of wheat’s marginal effects, the Agricultural Group of our university combined with the experimental station of the surrounding brigade. In the autumn of 1975, a marginal effect test scheme for measuring 1-inch hollow zone was designed: the wheat row spacing is 5 inches and each row is 11 rows Leave a 1-foot empty belt, and close to the empty side of the line called the side line, close to the side line of the next line, the line within the line of the seven lines. The traits and yield of wheat were investigated and determined during plant growth and harvest (see Table 1).
