践踏

According to the habitat types, weed species can be induced into 5 species groups. In the edge habitat, species were almost perennials which can endure dankness. In abandoned habitat with debris, species were tall perennials of Compositae. In abandoned habitat with soil, species were almost annuals which can endure leanness. Short-lived species appeared in spring in the habitat with human disturbance taking no care of environment effects. Species which can endure trampling were prostrate perennials

林下—林缘型种组所包含的物种多是多年生耐阴湿物种；废弃空地型种组所包含的物种多是多年生菊科高茎草；废弃空地型所包含的物种多是一年生耐贫瘠物种，亦有草质藤本葎草；春季短寿命型种组所包含的物种多是冬季一年生物种，在春季短时间占据生境，不能很好地体现生境特征；耐践踏型种组所包含的物种多是多年生匍匐、耐践踏物种。

Viridescence of equestrian orchid colour and lustre, in northern region green period can amount to 280 days of above; Ma Lan's purple beautiful quietly elegant is beautiful, nectar faint scent, florescence is as long as 50 days, still can serve as the material that cut a flower; Malannai tramples, after experience tramples, need not breed can ego restores; Moderate of height of equestrian orchid plant, the leaf is much and erect grow, have stronger aspiration, decrease dry, drop in temperature action; Equestrian orchid vitality is strong, do not need daily conserve basically, managing water fertilizer and management are devoted; In the city that build plant segregation of two side afforest takes open greenbelt, road to wait with ground of compose flowers and plants in, ma Lan is unquestionable high grade material.

马兰色泽青绿，在北方地区绿期可达280天以上；马兰紫色的花淡雅漂亮，花蜜清香，花期长达50天，还可作为切花材料；马兰耐践踏，经历践踏后无须培育即可自我恢复；马兰植株高矮适中，叶多而竖立生长，具有较强的吸尘。减燥。降温作用；马兰生命力强，基本不需要日常养护，节约了水肥和治理投入；在建植城市开放绿地。道路两侧绿化隔离带和缀花草地等中，马兰是无可争议的优质材料。

And a experiment was conducted to examine the response of the wear resistance of Shanghai JD-1 Zoysia to compound fertilizer under traffic stress, which was made by traffic machine.

践踏胁迫对上海"JD-1结缕草"生长及生理的影响 1.1不同践踏胁迫下草坪草的生长状况和坪用质量均有不同程度的下降。

It could be concluded that compound fertilizer could improve the trampling resistance of Shanghai JD-1 Zoysia and 50 g/m^2 were optimum application rate.

氮、磷、钾复合肥能够有效减轻践踏对结缕草的胁迫程度，提高结缕草草坪的耐践踏性。

Different changes of POD activity show experiment species have different adaptative mechanisms to traffic stress in quenching activated oxygen.

利用测试的生长生理指标，采用AHP模型对不同践踏处理下三种草坪草耐践踏性进行综合评价。

Heddewigii, Dianthus barbatus L, Dianthus latifolius, Dianthus caryophyllus and Dianthus chinensis var. liaotungensis, with relatively high fructification rates and certain traffic tolerance, showed little difference in ecological adaptability and exhibited an average seedling height of 20cm and a mean crown size of 23cm, and pruning during the late growth period could obviously promote flowering and reduce the seedling height by 3cm. While Dianthus barbatus L. and Dianthus phlox subulata, with relatively low fructification rates and higher traffic tolerance, had an unobvious difference in ecological adaptability, which present an average seedling height of 14cm and a mean crown size of 36cm, and pruning during the late growth period could promote flowering to some extent and reduce the seedling height by 2cm.

其中，大红石竹、锦团石竹、五彩石竹、五寸石竹、浓香石竹、重瓣石竹品种间差异小，平均苗高20cm，冠幅23cm，结实率相对高，有一定耐践踏能力，在生长后期进行修剪能很好的促进开花并降低株高3cm；常夏石竹和美国地被石竹品种间差异小，平均苗高14cm，冠幅36cm，结实率低，耐践踏能力稍强，在生长后期进行修剪能较好地促进开花并降低株高2cm。

The effect of compound fertilize on the trampling resistance of Shanghai JD-1 Zoysia was tested through simulative tramper. The results showed that both aboveground phytomass and green grass rate were increased along with the application amount of compound fertilizer with or without the trampling stress.

通过践踏器模拟践踏，研究氮、磷、钾复合肥对践踏胁迫下上海&JD-1结缕草&草坪耐践踏性的影响，结果表明：非践踏区和践踏区内，结缕草Zoysia japonica的地上生物量和绿叶率随着复合肥用量的增加而增加。
