简述果树对缩剪的反应。

答案

参考答案:

缩剪亦称回缩。即在多年生枝上短截。缩剪反应特点是对剪口后部的枝条生长和潜伏芽的萌发有促进作用,对母枝则起到较强的削弱作用。其具体反应与缩剪程度、留枝强弱、伤口大小有关。如缩剪留强枝,伤口较小,缩剪适度,可促进剪口后部枝芽生长;过重则可抑制生长。缩剪的促进作用,常用于骨干枝、枝组或老树复壮更新上;削弱作用常用于骨干枝之间调节均衡、控制或削弱抚养枝上。

The UK has a well­respected higher education system and some of the top universities and research institutions in the world. But to those who are new to it all, sometimes it can be confusing.

October is usually the busiest month in the college calendar. Universities have something called Freshers’ Week for their newcomers. It’s a great opportunity to make new friends, join lots of clubs and settle into university life.

However, having just left the comfort of home and all your friends behind, the prospect(前景)of meeting lots of strangers in big halls can be nerve­wracking(令人头痛的). Where do you start? Who should you make friends with? Which clubs should you join?

Luckily, there will be thousands of others in the same boat as you worrying about starting their university social life on the right foot. So just take it all in slowly. Don’t rush into anything that you’ll regret for the next three years.

Here is some top advice from past students on how to survive Freshers’ Week:

●Learn rules. Make sure you know British social etiquette(礼节). Have a few wine glasses and snacks handy for your housemates and friends.

●Be kind. Sometimes cups of tea or even slices of toast can give you a head start in making friends.

●Be sociable. The more active you are, the more likely you’ll be to meet new people than if you’re someone who never leaves their room.

●Bring a doorstop. Keep your door open when you’re in and that sends positive messages to your neighbors that you’re friendly.

So with a bit of clever planning and effort, Freshers’ Week can give you a great start to your university life and soon you’ll be passing on your experience to next year’s new recruits
