结果枝组的含义是什么?其与骨干枝有何关系?

答案

参考答案:

结果枝组是指直接着生在各级骨干枝上、不断发展变化的、大大小小的枝群,是果树生长结果的基本单位。结果枝组以其体积大小、所含枝条多少、疏密程度和形态特征不同,又可分为大型、中型和小型枝组,紧密型和松散型枝组,多轴集团式和单轴鞭节式枝组等等。

结果枝组在骨干枝上配置的是否合理直接影响果树光能利用率的高低、是果树能否获得优质、丰产的又一个关键所在。结果枝组相对于骨干枝而言,一是变化较大、主要视所在空间大小和与周围枝组的关系而定;二是从属于其所着生的骨干枝,一般情况下、其粗度应控制在着生骨干枝直径的1/3左右,生长势也不能超过骨干枝。但在特殊情况下,结果枝组和骨干枝也是可以相互转化的。

Wonder why you can get angry so easily while your friend smiles all the time? It’s probably because you both have different personalities(个性).

Personality is also about how people think, behave, and react (反应) to everything around them from day to day.

So what makes people think and behave in certain ways?

Part of the reason is that people are born like this. A baby gets its blood type, genes (基因) and other physical things when it’s still inside its mother. These things may help decide what the baby will be like.

But one’s personality doesn’t stop here. Family life, school learning and life experiences can also make you the person you are. This doesn’t mean it’s impossible to change your personality. You can always try to make yourself better. Don’t get too worried about your shortcomings (缺点). Just accept them. This is a good way to start making changes.

If you don’t know how to make friends, find out why. Is it because you’re too shy? Tell yourself to smile at people. Start talking to people using warm greetings.

Don’t give yourself a hard time about it all. It’s not easy to change lifelong habits in one night. Keep working at it. One day you’ll see that you can turn over a new leaf and be a new you!
