近十年来我国油菜的单位面积产量增加很快,广大贫下中农在生产实践中积累了宝贵的经验。为了总结这些好经验,从中探索共同性的规律,我们曾借助P~(32)示踪原子来了解油菜一生中不同生育时期营养物质的运转与分配情况,借以探明这些丰产经验的理论依据。但我们在这方面的观察还是很初步的,仅作为资料提供参考。试验经过本试验分两个阶段进行,第一阶段在1963年冬到1964年春,用胜利油菜为材料,分
The yield per unit area of rapeseed in China has increased rapidly in recent ten years, and the vast majority of poor and middle-income peasants have accumulated valuable experience in production practice. In order to summarize these good experiences and explore the law of commonality, we have used the P ~ (32) tracer atom to understand the operation and distribution of nutrients in different growth stages of rape in order to explore the theoretical basis of these rich experiences. However, our observations in this regard are still very preliminary, only as a reference for information. The test is divided into two stages after the test. The first stage is from the winter of 1963 to the spring of 1964, with the victory rape as material,
