1试验材料及方法1.1试验材料大豆种子,等离子机。1.2试验处理采用大区对比法设计,不设重复。试验共设2个处理,通过等离子体机处理的种子为处理区,未经过处理的种子为对照区。处理1:黑农44,依兰县三道岗镇试验种植点,种植面积处理与对照各0.5hm2相邻种植。土壤为黑土,地势为岗地。肥力均匀一致。该地区属第二积温带。播种前6d用等离子体机对大豆种子进行处理(5月6日下午)。5月12日播种,随机带种肥施撒可富二铵 1 Test Materials and Methods 1.1 Test Materials Soybean seeds, plasma. 1.2 Tests using large area contrast design, no duplication. A total of two experiments were conducted in this experiment. Seeds processed by the plasma machine were treated areas, and untreated seeds were used as control areas. Treatment 1: Heinong 44, Sandaigang Town, Yilan County Experimental planting site, planting area treatment and control each 0.5hm2 adjacent planting. Soil is black soil, terrain for posts. Fertility uniform. The area is the second plot temperate zone. Soybean seeds were treated with a plasma machine 6 days before sowing (May 6 afternoon). May 12 sowing, random with fertilizer to spread diammonium
