 一、草坪病害发生的原因
First, the reasons for the occurrence of lawn diseases
草坪病害是在外界环境条件影响下草坪与病原相互作用并导致草坪草生病的过程,因此,影响草坪病害发生的基本因素有病原,感病寄主和环境条件。环境条件包括土壤栽培等非生物因素,人、气候、和昆虫及植物周围的微生物区系等生物因素。防治草坪病害必须重视环境条件的治理,使其有利于草坪草生长和抗病性的提高,而不利于病原的发生和发展,从而减轻或防止病害的发生。
Turfgrass disease is a process of interaction between turf and pathogen under the influence of external environment, which causes the disease of turfgrass. Environmental conditions include abiotic factors such as soil cultivation, biological factors such as human, climate, and insect and plant flora. Prevention and control of turfgrass diseases must pay attention to the treatment of environmental conditions, which is conducive to the growth and improvement of disease resistance, and is not conducive to the occurrence and development of pathogens, so as to reduce or prevent the occurrence of disease.
二、草坪综合治理
Two, lawn comprehensive management
1、土壤改良 1.1 草坪黑土层的控制 :形成:在化肥,杀菌剂的共同作用下,土壤中的生物种群由好氧占优势,转变成厌氧占优势,最终形成一种黑色的凝胶状物质。
Control of the 1, 1.1 lawn soil improvement: the formation of black soil in fertilizer, common fungicides, populations in the soil by biological aerobic anaerobic transformation into dominant, dominant, and ultimately the formation of a black gelatinous substance.
(2)用梳草的办法,将草坪内的枯草清除。
(2) the removal of the grass in the lawn with the method of combing grass.
(3)解决方法:通过实验确定主要以打孔加喷生物制剂进行土壤改良为主,以草皮的开挖和土壤的更换为辅。1.2 草土层的控制和降低土壤硬实性
(3) the solution: through the experiment to determine the main hole and spray biological agents for soil improvement, mainly to the excavation of the turf and soil replacement supplement. 1.2 of the soil and reduce soil grass hard
(4)危害:增加土壤的硬实性,降低根系层的透气、透水性,严重影响草坪生长。
(4): increase the hardness of the harm of soil, lower permeability, root layer, serious impact on turfgrass growth.
(5)用切根机对生长在土层之上、草毡层中的草根加以剪断破坏。
(5) cut the damage to the growth in the soil above, grass-roots grass carpet layer to be used in cutting machine.
(6)然后使用打孔机对草坪进行打孔。此时打孔的目的是使经过切根之后草坪的根系迅速向富含水分的土壤中延伸。 1.3 低洼处排水效果的改善,通过病害调查发现低洼处排水不良处草坪发病严重,采取做排水和用钢叉深穿刺草皮的办法解决。
(6) and then use the punching machine for punching lawn. This punch is designed to make the lawn root cut through the root after extended rapidly to the water rich soil. 1.3 low-lying drainage improvement by disease investigation found low-lying poor drainage at the lawn drainage and the incidence of serious, take the fork deep puncture SOD solution.
2、科学的喷灌 ,要让草坪生长良好,为各部分草坪建立相应的喷灌制度是十分必要的。我公司制定的喷灌制度主要有三个方面的内容:喷灌水量,喷灌频率,和喷灌时间。
2, scientific sprinkler irrigation, to make the lawn grow well, for each part of the lawn to establish the corresponding sprinkler system is very necessary. There are three main aspects of sprinkler irrigation system in our company: sprinkler irrigation, sprinkler irrigation frequency and irrigation time.
(1)喷灌时间:草坪何时需要喷灌的确定方法
(1) sprinkler irrigation: a method for determining the need for sprinkler irrigation
a.植株观察法
A. plant observation
当草坪草叶色变为灰绿色,失去光泽,叶尖开始卷曲时,显示草坪水分不足。此时,若不及时灌水,草将变黄,在极端情况下还会因缺水达到永久性萎蔫而死亡。
When the turf color is gray green, lose luster, tip to curl, show the lawn water shortage. At this time, if not timely irrigation, grass will turn yellow, but also died for lack of water to achieve a permanent wilting in extreme cases.
b.土壤含水量检测法
B. soil moisture measurement method
用螺丝刀分层取土。湿润土壤呈暗黑色,干旱的土壤呈浅白色。
Use a screwdriver to layered soil. The wet soil was dark black, and the dry soil was pale white.
(2)具体操作时间
(2) specific operation time
最佳的喷灌时间是夜间与清晨
The best irrigation time is night and early morning
夜间进行喷灌有利方面是最充分的利用水分,不利方面是草坪潮湿时间过长,会诱发病害的发生。
At night, the best use of sprinkler irrigation is the best use of water, the negative aspects of the lawn is too wet, will lead to disease.
清晨喷灌的好处,清除草坪叶面的露水,减少病害发生。
In the early morning, the benefits of sprinkler irrigation, removing the dew on the lawn, reduce the occurrence of disease.
综合来看,春秋季可安排傍晚浇水,夏季安排清晨浇水。
On the whole, the spring and autumn can be arranged in the evening watering, summer arrangements early watering.
2.2 喷灌水量
2.2 sprinkler irrigation
每次浇水要浇足、浇透,不能只浇湿表面。
Each time the water should be poured, poured, not only wet surface.
2.3 喷灌频率
2.3 sprinkler frequency
草坪的喷灌应遵循大量、少次的原则,尽可能减少浇水次数。
Lawn sprinkler irrigation should follow the principle of a large number of times, as far as possible to reduce the number of watering.
