【正文】 嫁接苗：嫁接部位以上芽全部保留，嫁接部位以下芽全部抹掉。微繁苗或原種苗：所有萌芽全部保留。因而不需要修剪、整形，任其叢生生長(zhǎng)即可。進(jìn)入盛果期后，樹體將維持現(xiàn)狀，不再有徒長(zhǎng)枝生成。個(gè)別地區(qū)發(fā)現(xiàn)有“金龜子”吞食核桃樹葉。第二天早晨，將毒死的金龜子放入塑料袋中，扎緊袋口，置于太陽(yáng)下暴曬三日。八、薄皮核桃核桃什么季節(jié)成熟？ 核桃成熟季節(jié)一般是“處暑”季節(jié)（陽(yáng)歷8月中旬）。一般3天即可曬干。此時(shí)的核桃苗已經(jīng)封頂不抽新梢，基本進(jìn)入休眠狀態(tài)，此時(shí)移栽后，在封凍前，核桃苗正萌發(fā)新根，對(duì)來(lái)年的長(zhǎng)勢(shì)非常有利。 封凍前栽植，此時(shí)的核桃苗已經(jīng)進(jìn)入完全休眠狀態(tài)，移栽過(guò)程中，樹苗像在“夢(mèng)”中，移栽后，春暖后樹苗直接萌動(dòng)扎根，避免了損傷，成活率也很高，當(dāng)年樹冠一般在23平方米。 春末栽植，此時(shí)的樹苗已經(jīng)在土壤中扎根，移栽過(guò)程中樹苗損傷嚴(yán)重，緩苗特慢成活率不足50%，當(dāng)年基本沒(méi)有樹冠。所以人們常說(shuō)，“秋（末）冬栽樹一場(chǎng)夢(mèng)，春天栽樹一場(chǎng)病，夏天栽樹要它命”。核桃是食品中的佼佼者，歷代醫(yī)書中對(duì)其保健作用極為推崇，稱其能“通經(jīng)絡(luò)、潤(rùn)血脈，黑須發(fā)，常服皮肉細(xì)膩光潤(rùn)”。核桃既可生食、炒食，也可以榨油、配制糕點(diǎn)、糖果等，不僅味美，而且營(yíng)養(yǎng)價(jià)值也很高，被譽(yù)為“萬(wàn)歲子”、“長(zhǎng)壽果”。在西歐各國(guó)它又是圣誕節(jié)等一些傳統(tǒng)節(jié)日的節(jié)日食品。 核桃營(yíng)養(yǎng)豐富，含有豐富的蛋白質(zhì)、脂肪，礦物質(zhì)和維生素。脂肪中含亞油酸多，營(yíng)養(yǎng)價(jià)值較高，此外，還含有豐富的維生素B、E。核桃中還含有特殊的維生素成分，不但不升高膽固醇，還能減少腸道對(duì)膽固醇的吸收，適合動(dòng)脈硬化、高血壓和冠心病人食用。 核桃仁還含有多種人體需要的微量元素，是中成藥的重要輔料，有順氣補(bǔ)血，止咳化痰，潤(rùn)肺補(bǔ)腎等功能。 二、核桃的吃法核桃的吃法很多，除了直接敲開(kāi)吃以外，琥珀核桃、椒鹽核桃都是很好的選擇。 不過(guò)核桃火氣大，含油脂多，吃多了會(huì)令人上火和惡心，正在上火、腹瀉的人不宜吃。最后一個(gè)辦法就是生吃了，簡(jiǎn)單方便，有營(yíng)養(yǎng)。Types of burnsFirst degree burns These affect only the top layer of the skin. These burns are not serious and should feel better within a day or two. Examples include mild sunburn and burns caused by touching a hot pan, stove or iron for a moment.Third degree burns These affect all three layers of the skin and any tissue and organs under the skin. Examples include burns caused by electric shocks, burning clothes, or severe petrol fires. These burns cause very severe injuries and the victim must go to hospital at once.First degree burns ●dry, red and mildly swollen● turn white when pressed● blisters ● extremely painful ● swollen。 ● little or no pain if nerves are damaged。may be pain around edge of injured are.Remove clothing using scissors if necessary unless it is stuck to the burn. Take off other clothing and jewelry near the burn.For first degree burns, place cool, clean, wet cloths on them until the pain is not so bad. For second degree burns, keep cloths cool by putting them back in a basin of cold water, squeezing them out and placing them on the burned area over and over again for about an hour until the pain is not so bad.Cover the burned area with a dry, clean bandage that will not stick to the skin. Hold the bandage in place with tape. Never put butter, oil or ointment on burns as they keep the heat in the wounds and may cause infection.If the injuries are second or third degree burns, it is vital to get the victim to the doctor or hospital at once. HEROIC TEENAGER RECEIVES AWARDJohn was presented with his award at a ceremony which recognized the bravery of ten people who had saved the life of another.It was John’s quick action and knowledge of first aid that saved Ms Slade’s life. He immediately asked a number of nearby people for bandages, but when nobody could put their hands on any, his father got some tea towels and tape from their house. John used these to treat the most severe injuries to Ms Slade’s hands. He slowed the bleeding by applying pressure to the wounds until the police and ambulance arrived.John had taken parting in the Young Lifesaver Scheme at his high school. When congratulating John, Mr Alan Southerton, Director of the Young Lifesaver Scheme said, “There is no doubt that John’s quick thinking and the first aid skills he learned at school saved Ms Slade’s life. It shows that a knowledge of first aid can make a real difference.”Unit 1Art is influenced by the customs and faith of a people. Styles in Western art have changed many times. As there are so many different styles of Western art, it would be impossible to describe all of them in such a short text. Consequently, this text will describe only the most important ones, starting from the sixth century AD.During the Middle Ages, the main aim of painters was to represent religious themes. A conventional artist of this period was not interested in showing nature and people as they really were. A typical picture at this time was full of religious symbols, which created a feeling of respect and love for God. But it was evident that ideas were changing in the 13th century when painters like Giotto di Bondone began to paint religious scenes in a more realistic way.During the Renaissance, new ideas and values gradually replaced those held in the Middle Ages. People began to concentrate less on religious themes and adopt a more humanistic attitude to life. At the same time painters returned to classical Roman and Greek ideas about art. They tried to paint people and nature as they really were. Rich people wanted to possess their own paintings. so they could decorate their superb palaces and great houses. They paid famous artists to paint pictures of themselves, their houses and possessions as well as their activities and achievements.Impressionism (late 19th to early 20th century
