茶树营养诊断

答案

参考答案:通过分析土壤养分状况和植物营养状况确定茶树生育过程中对各种营养元素需求程度的技术。主要方法有:①目测诊断,根据缺肥茶树生长过程中的叶色、长相和树势等,与营养条件最适茶树相比较,从而确定缺素内容;②植株化学分析诊断,根据在规定时间对茶树指示器官(或部位)的营养元素含量进行化学分析,与营养条件最适茶树进行对照。确定缺索内容;③土壤农化诊断,根据对茶园土壤的农化分析,与营养条件最适土壤条件相对照.确定土壤缺索内容。在实际生产中,常将三者并用.进行综合分析和判断,然后断定缺肥程度,采取相应施肥方法。是茶园配方施肥和平衡施肥的基础。

The common Chinese greeting of “Ni chi le ma?” may soon be replaced by a new greeting: “Have you cleaned your plate?”

Over the Spring Festival holiday there was a big effort to get people to curb their habit of ordering too much food in restaurants because a lot of that food ended up being wasted. Holiday eaters were urged to “clean their plates” and were asked to take leftover food home in “doggy bags.”

The impetus behind the campaign was the startling government statistic that over 200 billion yuan is spent every year on food that ends up in the garbage bin. And in the midst of all this waste, statistics show that 128 million people are living below the poverty line and going hungry.

The “clean your plate” campaign is part of a worldwide effort to stop precious food from being wasted. The United Nations estimates that $1trillion (yes, that’s a very big number) worth of food is wasted each year. Most of that is lost during food production and transportation, but a significant percentage is attributed to waste by consumers. The United Nations Environment Program (UNEP) has launched a campaign called “Think. Eat. Save.” to make people aware of the problem.

Chinese actress Fan Bingbing is an ambassador for UNEP and she encouraged people to upload pictures of their “clean plates” to show their support for the program. Thousands of people responded and demonstrated that they had a clear conscience to go along with their full stomachs.

Xi Jinping, the incoming Chinese president, is also urging people to be less wasteful and he told Party members to cut back on extravagant holiday banquets and to be more careful when spending the people’s money.

For some, though, Xi Jinping’s and Fan Bingbing’s admonitions don’t go far enough. Yuan Longping, an agricultural scientist, caused a stir by saying that wasting food should be treated as a crime. (Jail time for leftover chicken feet!?)

If not a crime, wasting food is certainly a sin and it goes against what Xi Jinping calls, “the Chinese tradition of being diligent and thrifty.” Having a “clean plate” is just a traditional and responsible thing to do.
