桑树是怎样发育生长的?

答案

参考答案:

当早春气温上升到12℃以上时,桑树条上的芽开始膨大萌发,随着气温上升而伸梢展叶。5月初开始养蚕,当时新梢条已有10片左右桑叶,并迅速旺盛生长。到5月下旬新梢长到20多片叶,家蚕大量食桑,桑园成片收获,一般每亩能收获750-1000公斤桑叶。到5月底春蚕上簇结束时,要将桑条齐拳全部伐去(夏伐),重新发芽抽条,用再生长的桑叶可养2次秋蚕。10月初晚秋蚕结束,桑叶生长已经十分缓慢。当气温低于12℃时就停止生长,落叶休眠。桑园管理要“养一次蚕,施一次肥”,肥水足的桑叶大幅度增产,春叶就能有1500公斤。

The clock rules our lives. The more we try to save time, the less time we seem to have. In every area of our lives we are doing things faster. And many of us live in towns and cities which are getting noisier and more stressful as each day passes. But now a worldwide movement, whose aim is to slow life down, has started. Its supporters are people who believe that a happier and healthier way of life is possible.

The Slow Food movement was founded the day that an Italian journalist, Carlo Petrini, saw that McDonald’s had opened a restaurant in a beautiful square in Rome. He thought it was sad that many people today live too quickly to sit down for a proper meal and only eat much fast food. He decided that he had to try to do something about it and so he started the Slow Food movement. Slow Food has become a global organization ever since and now has more than 80,000 members in 100 countries.

Slow Food also encourages people to eat local and regional food, to use local shops and markets, to eat out in small family restaurants, and to cook with traditional recipes.

The idea of Slow Cities was inspired by the Slow Food movement. The aim of Slow Cities is to improve people’s quality of life. Towns which want to become a Slow City have to reduce traffic and noise, increase the number of green areas, plant trees, build pedestrian zones, and promote local businesses and traditions. Now it has spread to other countries all over the world, from the UK to Japan and Australia. There are now 135 Slow Cities in 24 countries across the world that have been named since founding of the organization in 1999. Gao Chun County, in east China’s Jiangsu Province, is expected to be named the first “Slow City” in China next year.

“Slow Cities are about having a community life in the town,” said a local resident. “It is not ‘slow’ as in ‘stupid’. It is ‘slow’ as in the opposite of ‘worried’ and ‘stressful’.”

But not everybody is happy. For teenagers, who have to go 25km to Norwich, the nearest city, to buy CDs, living in a Slow City is not very attractive. “It’s all right here,” says Lewis Cook, 16. “But if you want excitement, you have to go to Norwich. We need more things here for young people.”
