摘要： 大白菜干烧心病是缺钙性生理病害,自1970年以来在我国北方大白菜产区危害日趋严重.此项研究的重点是从“心叶补钙”入手探索经济有效的防治方法.从结球始期应用0.7%有水氯化钙附加50ppm萘乙酸进行“心叶补钙”.经8年连续试验,防治效果可达80%以上.采用常规分析和45Ca示踪试验的方法,证实了萘乙酸对钙素的吸收和运转有明显的促进作用,为改进大白菜干烧心病的防治方法提供了理论依据.

Abstract: The tip burn of Chinese cabbage is a physiological disease of the calcium deficiency, In the northern China the Chinese cabbage production areas are damaged seriously day by day from 1970. The focal point of this research worK is to probe into the economic and effective control method with interior leaf spray calciferous salt solution, The interior leaf is sprayed with 0,7% CaCl2·2H20+50PPm NAA at beginning of bearing fruit, It has been showed that effective control has reached over 80% for 8 years conti-experiment,Using the routine analysis method and 45 Ca trace experiment, it has been demonstrated that NAA can promote obviously calcium absorbing and transporting, and has provided theoretical evidence to improve the control method of the tip burn of Chinese cabbage.
Key words:
Tip burn of Chinese cabbage,
Spraying calciferous salt solution for interior leaf
