快中子对大豆的诱变效应

THE HUMBLE OPINION ABOUT THE REFORM OF THE CROPPING SYSTEM ON NONIRRIGATED FARMLAND OF CHANGCHUN

摘要:

用不同注量的快中子照射大豆风干种子的试验表明,快中子对大豆的M₁代的苗高、成株率和孕性有明显的损伤效应,而且对M₂的叶绿素和株高、孕性、熟期等农艺性状均有诱变效应。不同品种对快中子的辐射敏感性不同,九农9号较吉林18敏感。试验还表明,快中子是大豆的良好诱变源。

Abstract:

On the basis of the existing problems of the cropping system and the essential agricultural feature in Changchun, this treatise puts foward a series of ideas to improve the present cropping system.
These include regulating the distribution of crops in agricultural production, carrying out the system of ploughing the land periodically to create the good soil structure and returning the smashed crop stubble to the farmland to raise the fertility of soil as well as less-or non-tillage and full one-time-ferlilizion for achieving the increase of production and income. Doing so may be the way to develop the cropping system from primary situation to modern intensive farming step by step.
