辽阳草坪种植修剪有什么原则？一般什么时候修剪比较好？

草坪的修剪，不是推着草坪机剪一剪就好的事情。草坪修剪，首先要观察草坪的长势和病虫害情况，然后再做如何进行修剪的计划。

Mowing the lawn is not just a matter of pushing the lawn mower to cut it. In lawn mowing, we should first observe the growth of lawn and the situation of pests and diseases, and then make a plan of how to mow the lawn.

【1】草坪的修剪原则

[1] Principles of lawn mowing 

辽阳草坪种植修剪，应掌握1/3原则，对长得较高的草坪要分次进行修剪，不能一次剪到所需要的高度。每次修剪剪去1/3的叶片或高度，要使草坪具有正常的光合作用。若一次修剪到需要高度，则草坪同化产物的能力降低，容易使草坪退化，甚至死亡。

The principle of 1/3 should be mastered in lawn mowing. The higher-growing lawn should be mowed in different stages, not at the required height at one time. Cut 1/3 of the leaves or height each time to make the lawn have normal photosynthesis. If the turf is cut to the required height at one time, the ability of assimilation products will be reduced, and the turf will degrade or even die easily.

【2】旺草适度调高修剪

在辽阳草坪基地生长过旺时，应尽量的调高草坪的修剪高度，修剪后可间隔3—5天再进行调整到正常高度进行修剪，以使成熟叶片得到缓冲修剪。这样可以避免草坪受到光危害，也就是我们说的日灼。因为草坪生长过高，下面的草茎长时间适应荫蔽环境，剪得过低，则完全暴露在光照下，极容易造成灼伤。

When the lawn grows too fast, the height of the lawn should be adjusted as high as possible. After trimming, the height of the lawn should be adjusted to the normal height after 3-5 days, so that the mature leaves can be buffered and trimmed. This will prevent the lawn from being damaged by light, which is what we call sunburn. Because the lawn grows too high, the grass stems below adapt to the shady environment for a long time, and cut too low, they are completely exposed to light, which is very easy to cause burns. 

【3】修剪不宜过频或过久，要确定修剪频率。

[3] The pruning frequency should not be too high or too long, but should be determined. 

辽阳草坪草修剪频率取决于草坪草生长的快慢。有些草生长速度快，就要勤修剪，有的则生长缓慢，修剪次数就要减少。如假俭草相对就修剪次数少，而狗牙根和地毯草则修剪就频繁。细羊茅和紫羊茅的修剪次数也少。当然这也是不是确定的，如果氮肥施用充足，则生长快，修剪就勤。另外暖季型草坪夏季修剪相对频繁，秋季则冷季型草坪修剪相对频繁。

The frequency of lawn grass mowing depends on the growth rate of lawn grass. Some grasses grow fast and need to be pruned diligently. Others grow slowly and the number of times of pruning will be reduced. For example, the pruning frequency is relatively low, while the pruning frequency is frequent for canine root and carpet grass. Festuca arundinacea and Festuca arundinacea were pruned less frequently. Of course, this is not certain. If nitrogen fertilizer is applied adequately, it will grow fast and prune regularly. In addition, warm-season lawn mowing is relatively frequent in summer, while cold-season lawn mowing is relatively frequent in autumn.

【4】修剪与草坪的水分有一定关系

[4] There is a certain relationship between mowing and water content of lawn. 

在合适的草坪水分管理情况下，灌水量越大，草坪的修剪次数越频繁。反之在干旱的条件下，草坪生长缓慢，则修剪次数就少。在刚灌过水或土壤较潮湿的情况下不要修剪。

[4] There is a certain relationship between turf mowing and water content. Under the suitable water management condition, the more irrigation, the more frequent the lawn mowing. Conversely, under drought conditions, the lawn grows slowly, and the number of times of pruning is less. Do not prune the soil when it has just been irrigated or when it is wet.

【5】修剪的草屑处理

草坪修剪后的草屑，应及时清理出去。虽然草屑可以为草坪提供营养，但草屑不利于草坪的通风和光照，容易使草坪长势变弱和病害发生。如果需要草屑归还草坪内，应经过腐熟后再适量撒入。

The grass debris after lawn mowing should be cleared out in time. Although grass scraps can provide nutrition for lawn, they are not conducive to the ventilation and illumination of lawn, and can easily weaken the growth of lawn and cause diseases. If grass scraps need to be returned to the lawn, they should be decomposed and then properly sprinkled into the lawn.
