Effects of water stress on the photosynthesis physiological index of field Apple-pear tree and the potted Apple-pear and stock were studied.
水分胁迫对苹果梨树光合生理指标影响的结果表明：对于田间苹果梨，Pn的年变化同PAR的年变化趋势大体相同，都呈双峰曲线：Pn的日变化呈双峰曲线，有明显的“午休”现象，PAR日变化呈“抛物线”型；干旱可大幅度降低Pn值，处理后60天左右Pn值降至最低；浇水在胁迫前期Pn值下降，后期Pn值上升；覆草效果最佳，提高Pn值的同时，还可保水保墒；覆草和浇水叶绿素含量均比对照高，而干旱比对照低；干旱使叶片可溶性糖含量增加，浇水使其减少，短期恢复灌水，恢复较慢；浇水和干旱处理的脯氨酸含量均比对照高，干旱处理的田间苹果梨第18天至28天为脯氨酸的迅猛增长期，短期恢复灌水，干旱未能恢复正常状态，而浇水处理恢复较慢；叶片SOD含量先增后减，且干旱和浇水均比对照高，覆草一直呈平稳上升趋势，且低于其它三个处理：叶片MDA增加，增加幅度：干旱〉浇水〉覆草；覆草可以明显提高单产、改善苹果梨果实的外在品质。

海林梨树瀑布
海林梨树瀑布位于柴河镇境内头道河子支流梨树沟，是一瀑布群落，俗称吊水湖。由于此处山谷又深又窄，宽度10米，在上下200多米长的峡谷中，有10多处形态各异的瀑布景观，有的最高落差达9米多，有的则化为三级跌水，有的在飞瀑水帘后面还有“水帘洞”。由海林镇和柴河镇都有公路和乡路通达，过梨树村之后为山路。当年杨子荣为追歼残匪的英雄故事在群众中流传。周围山峦森林浓密。
