我们从1959—1966年进行了油菜磷素营养与磷肥有效施用技术的研究。全部研究工作包括油菜磷素营养的规律性与油菜磷肥有效施用技术两大部分。关于油菜磷素营养规律性的研究结果已作专题报道(见本刊上期本文Ⅰ报)。这里综合报道关于油菜磷肥有效施用技术的研究结果。 一、研究工作的基本情况 油菜磷肥有效施用技术的研究以田间试验为主,并利用同位素P~(32)示踪配合土培试验。(?)年的研究讲度如下-1 1959—1961年
We conducted from 1959 to 1966 Rape phosphorus nutrition and phosphorus fertilizer application techniques. All the research work includes the regularity of phosphorus nutrition in rape and the effective application technology of rape phosphorus. The results on the regularity of phosphorus nutrition in rapeseed have been reported in special reports (see the first issue of this paper I reported). This comprehensive report on the effective application of rape phosphate fertilizer research results. First, the basic situation of research The effective application of Rape P fertilizer research field trials, and the use of isotope P ~ (32) trace with soil culture test. (?) Years of research are as follows -1 1959-1961 years
