It was prepared by Technical Committee AW/1, Nursery stock. A list of organizations represented on this committee can be obtained on request to it

9、s secretary.SupersessionThis part of BS 3936 supersedes BS 3936-4:1984 and BS 3936-5:1985, which are withdrawn.Information about this documentBS 3936 is published in eight parts: Part 1: Specification for trees and shrubs; Part 2: Specification for roses; Part 3: Specification for fruit plants; Part

10、 4: Specification for forest trees, poplars and willows; Part 7: Specification for bedding plants; Part 9: Specification for bulbs, corms and tubers; Part 10: Specification for ground cover plants; Part 11: Specification for container-grown culinary herbs.BS 3936-4 was originally published at the re

11、quest of the Horticultural Trades Association and the National Farmers Union. This revision has been prepared following a periodic review.The market for wood from fast-grown poplars available when BS 3936-5 was first prepared has largely disappeared. Poplar and willow varieties are currently planted

12、 for amenity and biomass. Poplars are also included in the provisions of the Forest Reproductive Material Regulations 1. As the former parts 4 and 5 had increasingly much in common, they are now combined.The species listed in the tables in Annex A include all those named in recent publications descr

Details of sources are given in Annex A.Attention is drawn to the Forest Reproductive Material Regulations 2002 1 and the Plant Health (Great Britain) Order 1993 2. See Annex B.This document conforms closely to standards set by the National Plant Specifi

14、cation published by the Horticultural Trades Association 3 and guidance from the Joint Council for Landscape Industries 4 and is consistent with best contemporary forestry nursery practice.Plants marketed and supplied to this specification as forest nursery stock meet the requirements for Forestry C

16、I 2007It is a characteristic of crop husbandry that periodically, pests or diseases unexpectedly become more virulent than previously, and invalidate earlier recommendations based on many years of experience and practice. Regrettably, varieties of willow and poplar grown widely for biomass have rece

17、ntly suffered seriously from attacks of rusts and other fungal diseases. As a consequence, all lists of willow and poplar cultivars recommended as forest nursery stock are being revised. As it is uncertain when definitive lists will finally be available, recommended willow and poplar cultivar lists

18、are not included in this edition of this British Standard.Many of the tree species and varieties listed in Annex A are also grown onto larger sizes for amenity planting. BS 3936-1 specifies requirements for such stock.Presentational conventionsThe provisions of this standard are presented in roman (

19、i.e. upright) type. Its requirements are expressed in sentences in which the principal auxiliary verb is “shall”.Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publicat

20、ion does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.Compliance with a British Standard cannot confer immunity from legal obligations. BSI 2007 1BS 3936-4:20071 ScopeThis part of BS 3936 specifies requirements for forest nurser

21、y stock of a size suitable for planting or replanting of woodlands, woodland landscapes and land required for other purposes involving trees such as production of Christmas trees and production of biomass.It also specifies requirements for planting stock of poplars and willows.BS 3936-4 is relevant

22、to the supply of the young trees and shrubs for planting in woodland that falls within the scope of the Forest Reproductive Material (FRM) Regulations 1. It is not limited to such uses and can be applied to similar plants supplied for any woodland or landscape project.It includes specifications for

23、plant description, plant dimensions, health and condition, labelling, and packaging and storage, both for field-grown and for cell-grown plants.Requirements specified for plants being grown for sale or for transfer through market processes include: naming their origin and provenance or variety and/o

24、r cultivar; age and the cultural system under which they are raised; dimensions, including height or length, diameter at a specified point or in relation to a given height; condition (health); and care when supplying stock to the planter.2 Normative referenceThe following normative document contains
