摘要
应用不同场强的磁化水浸种两种冬小麦，２年田间栽培试验结果表明，磁化水浸种使小麦种子发芽势、一级分蘖数、次生根数、株高、小区有效穗数、穗粒数、千粒重和产量分别提高了１２．２％、１３．７％、７０．３％、７．３％、１０．２％、１７．１％、４．３％和２４．４％，使生育期提前１ｄ～４ｄ。干旱严重的１９９４～１９９５年度增产幅度显著高于干旱较重的１９９５～１９９６年度，两种小麦所需的最佳磁场强度不同。
Two types of winter wheat seeds were soaked in different strength magnetized water. Two year field experiment on them showed that the treatments could increase the seed germinating energy,number of the first order tiller, number of se condary roots, plant height, number of a valid spike, number of grain spike, thousand grain weight and yield by 12.2%, 13.7%, 70.3%, 7.3%, 10.2%, 17.1%, 4.3% and 24.4% respectively compared with the control. The growth period was shifted 1 d～4 d earlier. The yield increase in serious drought period of 1994～1995 was much greater than that in the less serious drought period of 1995～1996. The optimum of magnetic field strength for the two types of wheat was different.
