塑料大棚豇豆春早熟栽培如何进行植株调整?

答案

参考答案:

蔓性豇豆在主蔓长30cm左右时及时吊绳引蔓。

主蔓第1花序以下萌生的侧蔓长到3~4cm时打掉,保证主蔓健壮生长。

豇豆侧枝易开花坐荚,因此,主蔓长至1.5~1.6m时打顶,促进主蔓中上部侧枝上的花芽开花结荚。

主蔓上发生的侧枝都要摘心,促进侧枝第1个花序的形成,利用侧枝上发出的结果枝结荚。但不同部位发生的侧枝,保留节位不同。下部发生较早的侧枝,保留10节左右;中部发生的侧枝,留5~7节;上部发生的侧枝,留2~3节。

A

It was midnight in Paris and we were rolling toward Avenue Bosguet. As we came to the Pont Alexandra Ⅲ, the taxi slowed down, for the traffic light was red against us, and then, without stopping, we sailed through the red in a sudden burst of speed. The same performance was repeated at the Alma Bridge. As I paid the driver, I asked him why he had driven through two red lights.

“You ought to be ashamed of yourself, breaking the law and endangering your life that way ,” I protested.

He looked at me, astonished. “Ashamed of myself? I am a law abiding(守法的)citizen and have no desire to get killed either.” He cut me off before I could protest.

“No, just listen to me before you complain .What did I do? Went through a red light. Well, did you ever stop to consider what a red light is, what it means?”

“Certainly,” I replied. “It’s a stop signal and means that traffic is rolling in the opposite direction.”

“Half-right,” said the driver, “but incomplete. It’s only an automatic stop signal. And it does not mean that there is cross traffic. Did you see any cross traffic during our trip? Of course not. I slowed down at the light, looked carefully to the right and to the left. Not another car on the street at this hour. Well, then! What would you have me do? Should I stop like a stupid animal because an automatic, brainless machine turns red every forty seconds? No, sir,” he shouted. “I am a man, not a machine. I have eyes and a brain and judgment, given me by God. Ashamed of myself, you say? I would only be ashamed of myself if I let those blinking lamps do my thinking for me. Good night ,sir.”

Is this bad, is this good? Frankly I am no longer sure...
