| 摘 要： | 本文研究了柑桔叶片脱落与产量的关系及三种柑桔病害对叶片脱落、叶片矿物质营养和果实内含物的影响.结果表明:6月以前和6月上旬～8月中旬春(?)叶的脱落与产量有极显著直线回归关系,后者的影响为最大;春梢叶脱落以黄化病化为最大,脚腐病次之,流胶病最小;对产量的影响以6月上旬～8月中旬为最大,6月以前次之.

| Abstract: | This paper has studied the relation of the leaf dropping with orange yield and three kinds of orange disease's influence upon leaf dropping,leaf mineral nutrition and fruit-content composition. The result has revealed that there is highly significant linear-regression relation between the spring leaf dropping before June and in June to the middle of August and the yield. And the effect of the latter is much greater. Of all effects of the three diseases of foot rot, gum flow and the yellows causing spring leaf dropping,the yellows' is the greatest,the foot rot's second and the gum flow's is the least. the strongest influence upon the yield is in June to the middle of August, too. The influence before June is the second. |
