Results showed activities of tourists have hardened the soil,reduced its organism content and water content, and increased its unit weight. Basically theseverity of the effects increases with the increase of tourist activity.The former scene of arborescence is now a tourist dense area.
对森林公园土壤的研究选择了四个景区:古驿道、毛竹林、竹类园和防火瞭望台,研究结果表明游客的活动使土壤的紧实度增加,有机质含量从2.33%减少到1.33%,土壤含水率34.42%从降低到21.87%,土壤容重从1.13 g/cm3增加到1.38 g/cm3,样地受影响的严重程度依次为竹类园>古驿道>防火瞭望台>毛竹林。

Thischaracteristic of Atriplex canescens is consistent with that of many local species. TheLCP of Atriplex canescens in different treatments (light, medium, no and heavy watersoil stress) are 314.8μmolm~(-2)s~(-1)、272.5μmolm~(-2)s~(-1)、176.7μmolm~(-2)s~(-1)、143.1μmolm~(-2)s~(-1), respectively, which indicates that the LCP of Atriplex canescens is reducingwith the escalation of soil water stress. This tendency is favorable for Atriplexcanescens under drought stress to maintain certain photosynthesis even in weaksunlight so as to ensure the survival of itself, and keep balance between maintainingwater content inside and its photosynthesis.
四翅滨藜在不同土壤水分胁迫下的光补偿点:轻度土壤水分胁迫、中度土壤水分胁迫、无土壤水分胁迫和重度土壤水分胁迫下的光补偿点分别为,314.8μmolm~(-2)s~(-1)、272.5μmolm~(-2)s~(-1)、176.7μmolm~(-2)s~(-1)、143.1μmolm~(-2)s~(-1),说明四翅滨藜的LCP随着土壤水分胁迫的加重而呈现降低的趋势,这种变化有利于处在干旱胁迫中的四翅滨藜在光强较弱的条件下仍然能维持一定的光合作用,以满足植物自身生命活动所需,同时也可以使植物在保持体内水分和进行光合作用之间寻找平衡。

People have paid attention to the pollution of soil and water quality caused by using organic arsenic chemistry reagent to prevent and cure apple-tree canker in our apple area, so it has an important purpose to seek a harm-free way for sustaining development of apple. The tests studied the effect of prevention and cure on apple-tree canker with EM mud, EM liquid, 40%'Fumeishen powder' and contrast. The results showed that the EM mud was superior to the EM liquid, 40% 'Fumeishen powder' and contrast. The prevention and cure effects of EM in 2006 and 2007 were 92.7% and 93.5%, while the recurrence rates of canker scars 1.8% and 2.8% respectively. And the healing effect of scar is 50.4%. So, it was considered as a new way to prevent and cure apple-tree canker with EM mud.
中国各苹果主产区果农长期使用有机砷等化学制剂防治腐烂病,对土壤、水质等环境造成的污染已引起人们的关注,寻求无公害的方法防治腐烂病,对苹果业可持续发展具有重要意义;本试验设EM活性菌泥涂抹、EM活性菌液涂抹、40%福美砷可湿性粉剂50倍液刮涂和对照(只刮除腐烂病疤,不涂药)4个处理,三次重复,进行了苹果树腐烂病的防治研究;结果表明,EM活性菌泥在防治效果、病疤复发率和促进病疤愈合效果方面均优于其它处理,其当年和第二年4月的防治效果分别为92.7%、93.5%,病疤复发率分别为1.8%、2.8%,促进病疤愈合效果也最好(50.4%);因此,作者提出,将EM活性菌融入粘泥载体中制成菌泥,涂抹在腐烂病疤上,以菌治菌,是防治苹果树腐烂病的新途径。
