1978—1980年,经过三年、四个单位、八个点次的试验结果表明,~(60)Co_γ射线刺激大豆生长,增加光合作用面积,促进干物质积累,提高单位面积产量。黑农26号大豆经2千伦和3千伦的γ射线照射比对照单产提高3.57-17.20%。黑农16号大豆经2千伦和3千伦照射比对照单产提高6.93-12.27%。经均数差异显著性测定,两个品种都是2千伦的达到显著和极显著标准。1980年,大面积对比试验,2千伦两地共25.63亩,平均增产10.07%,3千伦两地共22.30备,平均增产3.33%。因此,播前应用~Coγ射线照射大豆干种子,能够促进增产。适宜照射量为2千伦左右。
From 1978 to 1980, after three years, four units and eight points, the results showed that ~ (60) Co_γ ray stimulated the growth of soybean, increased photosynthetic area, promoted the accumulation of dry matter and increased yield per unit area. The increase of 3.57-17.20% in yield of Heinong 26 soybean by γ-ray irradiation of 2 1000 Lun and 3 000 Lunan was more than that of the control. Heinong 16 soybean by two thousand and three thousand Lun exposure than the control yield increased by 6.93-12.27%. After the significance of the difference was significant, the two cultivars reached the significant and extremely significant standard at 2 thousand. In 1980, a large area of comparative test, two thousand Lun Lun a total of 25.63 acres, an average yield of 10.07%, a total of 22.30 three thousand two Lun prepared, with an average yield of 3.33%. Therefore, pre-sowing ~ Coγ-ray irradiation of dried soybean seeds can promote the increase of yield. Suitable exposure for 2 thousand or so.
