关于工艺 Flashcards
Cutting 和 layering 为了? 用在哪里? 做法? 目前倾向于用哪种,为什么
目的:preserve the unique qualities of a variety
倾向于:cutting (Due to the risk of phylloxera)
Cutting: (commercial nurseries)that sell vines to growers
A section of a vine shoot that is planted and then grows as a new plant
Layering: (take place in vineyard)
A cane is bent down and a section of it is buried in the ground->
The cane tip points upwards out of the ground->
The buried section takes root, once the roots are established ->
Cut the cane that linking the new growth and the original plant
Clone和variety的关系
clone品种怎么得来
clone品种如何定义
clonal selection:
Positive mutation-> better quality fruit OR better disease resistance
-> selected for further propagation by layering/cutting
=> 得到clone品种
Shows a particular set of unique characteristics
cross-fertilisation
用于___。
create new grape varieties in controlled conditions.
寻找新品种是为了哪些方面的进步?(3)
- better able to thrive in certain climates and soil conditions
- Improve disease resistance
- Deliver a higher quality or quantity of grapes
crossings 和 hybrids
- 目的
- 做法(定义)
- 举例
目的: create new variety
crossing:用same species做parents (都是V.vinifera)
这个名词常指研究者培育的新品种
比如:
Müller Thurgau (Riesling X Madeleine Royale)
Pinotage (Pinot Noir X Cinsault)
Hybrids 父母至少有一方为American vine American vine很少用于酿酒,所以它的hybrid也很少用,一般都是用于rootstock 但是例外有: Vidal (Canada)
rootstocks的益处
offers the protection of the American vine and the flavour of the European vine.
- resistance to Phylloxera
还有很多其它好处,所以人们培育更多hybrids作rootstock - can be used to protect against nematodes
- provide better resistance to drought conditions
所以即使phylloxera不严重的地方也会用rootstock
grafting是什么
两种方式,目前常用的是?
a technique used to join a rootstock to a V.vinifera variety
- bench grafting (specialist plant nurseries) joined together by machine
- head grafting(grape grower) 3年后才能有commercial crop产出
预防冰雹(2)
netting
owning several vineyard sites in different locations
Irrigation techniques:(3)
Drip irrigation
Sprinklers
Flood irrigation
Sunlight hazard的应对管理用什么方法
canopy management
冬天过冬保护graft的方法
earthing up
In area at risk from winter freeze, earth can be used to cover up and protect the graft
Spring frosts的应对:(4)
- Heaters
- Sprinklers
- Wind machines
- Thoughtful vineyard design
Waterlogged soil can be avoided by (2)
- Planting vines on a slope or on flat sites
2. Installing drainage pipes to aid the flow of water away from the roots.
Chlorosis的应对
Using an appropriate fertilizer
