| 如何给绿化草坪施肥呢？ How to fertilize the green lawn? 要想草坪上的好，长的茂盛，施肥是不可少的，那我们该如何给草坪施肥呢?下面跟随绿化草坪小编来了解下吧： Fertilization is indispensable for the lawn to grow well and flourish. How should we fertilize the lawn? Let's follow the green lawn knitting to learn about it. 施肥之前熟悉草坪营养特性： Familiar with turf nutritional characteristics before fertilization: 草坪同其他植物一样，正常生长所必需的16种营养元素，除C、H、O主要来自空气和水外，其他的都主要靠土壤和肥料提供。所以要能根据草坪的特性选择适当的肥料来施放，这样才能起到事半功倍的效果。 Like other plants, lawn is mainly supplied by soil and fertilizer, except that C, H and O are mainly from air and water. Therefore, it is necessary to select suitable fertilizer according to the characteristics of the lawn, so as to achieve twice the result with half the effort. 肥料用量： Fertilizer dosage: 草坪氮肥用量不宜过大，否则会引起草坪徒长增加修剪次数，并使草坪抵抗环境胁迫的能力降低，甚至一次肥量过大可能导致草坪发生枯萎的现象，一般高养护水平的草坪年施氮量每亩30至50公斤，低养护水平的草坪年施氮量每亩4公斤左右。 The amount of nitrogen fertilizer should not be too large. Otherwise, it will cause the lawn to grow longer, increase the times of pruning, and reduce the ability of lawn to resist environmental stress. Even if the amount of fertilizer is too large, it may lead to the phenomenon of lawn wilting. Generally, the annual amount of nitrogen applied to lawns with high maintenance level is 30 to 50 kilograms per mu, while that of lawns with low maintenance level is about 4 kilograms per mu. 施肥时期： Fertilization period: 一般情况下，暖季型草坪在一个生长季节可施肥两三次，春末夏初是最重要的施肥时期。南方地区暖季型草坪，可在秋季施一次缓释肥，避免草坪因缺肥而缺绿。冷季型草坪施肥时间是在晚夏、晚秋。 Generally, warm-season turf can be fertilized twice or three times in a growing season, and late spring and early summer are the most important fertilization periods. The warm-season turf in southern China can be treated with slow-release fertilizer once in autumn to avoid the lack of green due to lack of fertilizer. The fertilization time of cold season lawn is in late summer and autumn. 施肥方法： Fertilization methods: 草坪施肥均匀是关键，施肥不均匀，会破坏草坪的均一性，肥多处草生长快、颜色深而草面高出，从而降低草坪质量和使用价值。根据肥料的形态和草坪草的需肥特性，草坪施肥方法通常分喷施、撒施和点施。一般大面积草坪采用机械施肥，小面积草坪可采用人工施肥。人工施肥，通常是横向撒施一半、纵向撒施一半。施用液体肥料一定要掌握好浓度。固体肥料用量较少时，应用沙或细干土拌肥，目的是使肥料撒施更均匀。 Uniform fertilization is the key to lawn. Uneven fertilization will destroy the uniformity of lawn. Many grasses grow fast, have dark color and high grass surface, thus reducing the quality and use value of lawn. According to the form of fertilizer and the fertilizer requirement characteristics of lawn grass, the methods of lawn fertilization are usually divided into spraying, spraying and point application. Generally, mechanical fertilization is used for large area lawn, and manual fertilization is used for small area lawn. Artificial fertilization is usually applied half horizontally and half vertically. The concentration of liquid fertilizer must be well controlled. When the amount of solid fertilizer is small, sand or fine dry soil is used to mix fertilizer in order to make the fertilizer more uniform. |
