The A. turfgrass and sedum plants are a good variety of green roofs that can stand up to the test. It has the advantages of extreme heat resistance, extreme drought resistance, extreme cold resistance, and extensive management. However, necessary management is absolutely necessary, otherwise it will not grow well and it will even be completely destroyed. According to the eight years of experience and lessons from the cultivation of A. sinensis in Beijing, the following management rules have been formulated.
1. Maintain the beautiful and tidy state of the roof, clear large areas of fallen leaves, debris, and weeds in time, especially in the summer and autumn.
2, do a good job of drainage inspection during the rainy season, especially the drainage outlets, drainage ditch, etc., so as not to block the drainage outlet, if the drainage is not smooth, flooded the lawn flooded, sun exposure, Buddha grass will instantly die, so whenever it rains, The roof drainage must be checked in time.
3, pay attention to check the fullness of the roof substrate, found that the loss of matrix should be quickly added to ensure the normal growth of seedlings block, appropriate water supplement when the spring is a necessary measure.
4. Observe the growth status of the seedlings regularly, and supplement the seedlings with alopecia areata and uneven density.
5, carefully check the status of matrix soft and water, timely and appropriate amount of green roof watering to prevent the matrix plate. Especially when entering the winter, it is necessary to pour enough frozen water, pouring spring water before returning green in spring, and timely replenish water in summer drought. This is the focus of the conservation of A. sinensis.
6, pay attention to fertilization and disease prevention, pest control, and ensure the effectiveness of greening.
7. For seedlings of alien species such as poplar, eucalyptus, and willow, they must be removed in time. Since most roof turfs do not have a special root barrier waterproof layer, the strong root system not only robs the main plant of nutrients, but also destroys the waterproof structure over time, and then destroys the roof structure, which is likely to cause significant impact.
8, to the conservation on the roof, safety is the first, one is the safety of the staff, the other is the security of the house, should wear soft-soled shoes, all movements should be gentle, to prevent artificial damage to the roof, causing Leaking accident.
9, should pay attention to wind protection in winter, especially in the roof position of the outlet, should be properly set windproof, encountered particularly arid year, should be adequate water.
10. The conditional unit shall implement an automatic irrigation system on the roof lawn, which is conducive to water conservation, safety, and benefit to the growth and quality of the turf, and is conducive to urban civilization.
