Have you ever been to the football field? Xiao Bian believes that most people have been there. Maybe you are playing football on the football field now. You may be careful about the lawn of the football field. Is the grass real grass on the lawn? What if it's not a real grass? Then, by the small editor of the hundred safety net, take you to find the answer to the safe little knowledge of the "natural lawn of the football field".
The establishment of football field turf mainly includes planting time, grass seed selection, bed treatment and sowing.
(1) planting time: because of the different growth temperature of different grass species, there are some differences in the selection of planting time. The suitable growth temperature of the cold season turf grass is 15 - 25 C, so the construction of the cold season turf is mostly in the early spring and autumn. The sprinkler pressure of the spring sowing lawn is great, and it is vulnerable to the weeds. In contrast, the autumn is the best planting time. In the cold season arid areas in China, it is better to plant turf before the rainy season in early summer. The suitable growth temperature of warm season turf grass is 25 - 39''C, and the planting time of warm season turf is mainly in summer.
(2) turf bed treatment: turf bed treatment is an important step in building turf. It mainly includes soil cleaning, tillage, leveling, improvement, fertilization and installation of drainage irrigation system. We should carefully remove the debris and weeds in the flat bed, apply fine sand or peat to improve the permeability of the soil. According to the condition of the soil fertility, a proper amount of ammonium phosphate, compound fertilizer and organic fertilizer can be applied to the base fertilizer when sowing, and the suitable amount of fertilizer is 30 to 40 grams per square meter (organic manure can be properly increased) and the lawn is planted. The problem of ground drainage should be taken into full consideration.
(3) grass seed selection and mixing proportion: selecting suitable turf grass species suitable for local climate and soil conditions is an important prerequisite for successful planting turf. The basic principle is to choose the grass species suitable for local soil climate first, that is to choose the survival problem first, and then choose color, texture and homogeneity, secondly, it should be based on the following. Different management conditions choose suitable varieties for orderly complementation, so mixed seeding is generally adopted in football field turf. The important basis for mixing turf grass is that it is necessary to take full account of the uniformity of the appearance and texture of the mixed planting lawn, that is to say, there should be a complete and uniform landscape effect. The mixing and proportion of the grass species in different areas and in the same area are different, and the management conditions are good or bad, and the proportion of the mixed sowing is different.
(4) sowing method and sowing amount: football field lawn seeding to sowing mainly, the amount of sowing is different because of the variety, the amount of sowing of different grass seed can be consulted the relevant books.
