几种措施对大鸡心黄皮成花与产量的影响

试验结果表明：（1）间伐、间伐 环割、间伐 环剥等三种处理对促进大鸡心黄皮来花有明显的成效，间伐 环剥处理效果最好，其次是间伐 环割处理，采取单一措施间伐效果相对较差。（2）在四个处理中以间伐 环剥处理产量最高，其次是间伐 环割处理，第三是间伐处理。间伐、间伐 环剥、间伐 环割处理等三种处理主要是通过提高来花结果枝条数、单株结果数提高产量。建议在黄皮低产园造中结合间伐、断根，增施有机肥等措施根据树势合理使用环剥、环割措施。

Effect of the several measures On Flower and Yield of Large heart-shaped Wampee

The results showed that: (1)Three treatments including internally hag, internally hag circular snick, internally hag circular bark significantly promoted the flowering performance of large heart-shaped Wampee, internally hag circular bark treatment is the best, internally hag circular snick treatment followed, adoption of a single measure internally hag effect relatively poor. (2)In the aspect of yield obtained by the four treatments, internally hag circular bark get the highest, followed by internally hag circular snick treatment, and internally hag process the third. Three treatments of internally hag, internally hag circular snick, internally hag circular bark treatment increase yield mainly by raising the number of branches and the number of results per plant. Recommendations are flowing: in the Wampee garden with low-yield internally hag, root pruning, organic fertilizer and other measures based on the rational use of Tree growth conditions circular bark, circular snick.
