15、mmittee. BS7370 has been prepared in order to provide those responsible for the upkeep of land that has a recreational or amenity use, or a functional purpose that is not solely for agriculture, commercial horticulture or forestry, with a series of recommendations for the various aspects of such mai

16、ntenance. It has been assumed in the drafting of this British Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people, for whose guidance it has been prepared. This Part of BS7370 gives assistance in determining categories of amenity and functiona

17、l turf maintenance objectives for each turf category together with the provision of a means of assessing that the objectives of maintenance are being achieved. It also describes suitable maintenance programmes. BS7370 at present comprises the following parts: Part 1: Recommendations for establishing

18、 and managing grounds maintenance organizations and for design considerations related to maintenance; Part 2: Maintenance of hard areas 1) ; Part 3: Maintenance of amenity and functional turf (other than sports turf); Part 4: Maintenance of soft landscape (other than amenity turf) 1) ; Part 5: Maint

19、enance of water areas 1) . Further Parts may be prepared, as necessary.

General 0 Introduction The recommendations given in this Part of BS

22、7370 are intended: a) to assist users in determining categories of amenity and functional turf when compiling maintenance programmes; b) wherever possible, to set maintenance objectives for each turf category and to provide a means of assessing, with some form of measurement, that such standards of

23、maintenance are being achieved; c) to describe suitable maintenance programmes for each turf category. It is recognized that, in some circumstances, users may have to adjust the maintenance objectives to meet local conditions but it is recommended that the maintenance objectives described should be

24、followed wherever possible. 1 Scope This Part of BS7370 gives recommendations for categories of amenity and functional turf for different applications based on the minimum height of cut and the maximum recommended length to which the vegetation can grow before it becomes unsuitable for the intended

25、purpose. For each category of turf, recommended maintenance objectives are described based on suitability of the turf for the intended purpose and these include a series of suggested measurable parameters. Maintenance programmes for achieving these maintenance objectives are suggested, and informati

26、on is given on types of machinery, materials and equipment, and their applicability. The recommendations given in this Part of BS7370 are intended to apply to the maintenance of amenity and functional turf. They do not apply to sports turf. Recommendations for the production of turf for sale are giv

27、en in BS3969. Factors such as geographical and climatic conditions, which have an influence on management, are described in some detail, as are the patterns of growth throughout the UK. Management practices have to be varied according to the soil and the grass species used for a specific purpose. Th

28、e document therefore includes suggestions on the most suitable grass species for different applications. NOTEThe titles of the publications referred to in this standard are listed on the inside back cover. 2 Definitions For the purposes of this Part of BS7370 the following definitions apply. 2.1 aer

29、ation the operation of making a series of holes through a grass sward into the soil beneath, with round, flat or hollow tines, to improve the passage of air, moisture or nutrients 2.2 amenity grassland all grass with recreational, functional or aesthetic value, and of which agricultural productivity

30、 is not the primary aim 2.3 arisings grass clippings, cuttings, cores or other material removed from the sward by maintenance operations 2.4 banding the action of mowing grass so that adjacent passes are in the same direction, giving a resulting visual effect of stripes wider than a single cutting w

31、idth. (See also 2.73) 2.5 bent(s) 1) Reproductive stems of grasses standing out above a mown sward, particularly evident when temporarily flattened and therefore left uncut by cylinder mowers with front rollers. 2) Grasses of the genus Agrostis.BS7370-3:1991 2 BSI 03-1999 NOTEThis term is deprecated
