| 摘要: |
| 研究了梯度磁场对小麦、玉米及马铃薯苗期生长及产量的影响,并对其作用机制进行了初步探讨.结果表明,梯度磁场能促使农作物的种子、块茎等早萌发、早出苗,提高出苗率、促进幼苗生长发育,达到苗齐、苗壮、子粒饱满、提早成熟,并且显著地增加农作物的分蘖或分枝,提高产量达11%～45%.利用电子顺磁共振法测定了种子内自由基的浓度,并测定了淀粉酶及过氧化氢酶的活性,结果表明,梯度磁场处理能适当增加自由基浓度,使上述两种酶的活性均有提高. |

| Abstract: |
| Deals with the effect of gradient magnetic field on seedling growth and yields of wheat,corn and potatoes and studies on its mechnism of action.The result showed that the gradient magnetic field can increase the rate of emergence,accelerate seedling growth and development.Natably increased effective tiller and branch of crop.In all tests yield of crops was raised.By means of ESR technique the concentration of free radicals was mea- sured.The results showed that gradient magnetic fields increased concertrati... |
