Cold-proof skills of open-air flowers and trees

In winter, you can let some cold-tolerant flowers and bonsai overwinter outdoors naturally, but don't ignore the cold and warmth of these flowers and plants. Anti-freezing measures for flowers and trees planted on the ground: peach, plum, wintersweet, elm, magnolia, etc. Straw, wheat straw, old cloth, old cotton wool and other warm-keeping materials can be used to wrap the stem to keep warm. It can also be applied to the branches of flowers and trees that overwinter outdoors, which can not only effectively prevent freezing injury, but also play a role in preventing and controlling pests and diseases remaining on the branches. However, it should be noted that the whitening agent prepared with quicklime must be turned into hydrated lime before use, otherwise it will burn the branches of flowers and trees. The proportion of whitening agent is: 36-40 parts of water, 0-20 parts of quicklime/kloc-0, 2 parts of salt 1-2, 2 parts of clay and 2 parts of sulfur mixture stock solution. First, dissolve quicklime and salt and mix them evenly, then pour in the mixture of stone and sulfur and clay, mix them evenly and brush them into white. Don't run down the amount of paint.

Anti-freezing measures for cold-resistant herbaceous flowers: Cucurbita, Corydalis tricolor, kale, corn poppy, etc. In case of severe cold current or rainy and snowy weather, it can be covered with plastic film, grass stalks and other warm things, and then uncovered after the weather is fine to make the seedlings short and strong.

Anti-freezing measures for bulbous flowers: Canna, Dahlia and other bulbous flowers can be covered with compost soil, rotten leaves and hay if they need to overwinter outdoors and underground. And pay attention to keep the bulbs under the frozen soil, otherwise the bulbs will be frozen and the new buds will not grow in the next spring. Note that the lid cannot carry germ eggs.

Anti-freezing measures for cold-resistant potted plants: the best way is to bury the pot under the outdoor frozen soil layer to protect the roots from freezing damage; Plant ash can also be used to cover the basin surface, which not only has good heat preservation effect, but also has no side effects on flowers and trees. The flowers and trees that survived cutting in those years, because of their small plants and poor cold resistance, should be covered with warm things besides the main branches and leaves, and the pot soil should also be covered with plant ash or other warm things to keep warm.

Skillful use of aspirin in flower and tree cultivation

Aspirin, also known as acetylsalicylic acid, can be decomposed into salicylic acid and acetic acid in water. Salicylic acid has antibacterial, anti-inflammatory and antiseptic effects, while acetic acid can inhibit the biological activity of glycolate oxidase, improve the photosynthesis of flowers and trees and increase photosynthetic products. Aspirin has the following uses in production. 1, improve the survival rate: the root system of bare-rooted flowers and trees is soaked in 400-500mg/kg aspirin solution for 1-2 hours, taken out and dried for 8- 10 minutes, and planted immediately, which can improve the survival rate. When transplanting flower seedlings and stump bonsai, the root system is watered with 30-50 mg/kg aspirin solution, and the survival rate can reach above 95%. When cutting flowers and trees (hard branch cutting, tender branch cutting, leaf cutting, root cutting, etc.). ), watering or foliar spraying with 80 mg/kg aspirin solution can prevent the wound infection bacteria from rotting, promote the seedlings to produce callus in advance and improve the survival rate.

2. Promote robust growth: During the growth and development of flowers and trees, root irrigation with 300-500mg/kg aspirin solution every 7- 15 days/time can promote the robust growth of flowers and trees, with enlarged leaves, swollen fruits, gorgeous flowers and enhanced ornamental value.

3. Improve stress resistance: Spraying stems, branches and leaves of flowers and trees with 500 mg/kg aspirin solution can reduce water transpiration in plants and improve the ability of flowers and trees to resist drought environment. Combined with watering, watering or spraying aspirin (1 tablet dissolved in 0 kg water) can promote the closure of leaf stomata, reduce leaf water transpiration loss, reduce high temperature burns and improve the drought and cold resistance of flowers and trees.

4. Extend the life of flower arrangement: Aspirin can close the stomata of leaves and prevent the wound from producing jasmonic acid. Using 0.03% aspirin solution to arrange flowers can delay the withering time of flowers and prolong the fresh-keeping time of flowers by 7- 10 days.

5. Improve the survival rate of stumps: Treating the stumps bonsai with aspirin can make stumps germinate ahead of time, improve the survival rate and shorten the blank-raising time. The method is as follows: during the dormant period of the plant, the stump is dug to minimize the wound surface and keep more fibrous roots. At the same time, the roots, dead branches and waste branches are removed. The wound surface of the thicker root is sawed flat, and the branchlets are sawed flat with fruit branches. They are soaked in 5% aspirin solution for 3-5 hours, and the basin soil is made of river sand, pastoral soil and sawdust according to the ratio of 4:5: 1.

Love between master and flowers and trees

Plum blossoms were planted in the former residence of Qi Baishi, a master of Chinese painting. He named his studio Baimei Bookstore. Qi Baishi likes painting plum blossoms very much, but he seldom uses plum blossoms to imply Leng Yan's nobility, loneliness and arrogance. His "Painting Plum Poems" said: I don't know the lonely mountain and the moon when I shake my teeth, and each pair of plum blossoms is full of sweat. This means that his later years are different from Lin Hejing, who is called Mei's wife and the lonely mountain crane. Qi Baishi rented an ancestral temple when he was young, and the house was surrounded by plum trees. He called it Baimei Temple. When he paints plum blossoms, he often shows his nostalgia for that life. Qi Baishi painted plums and was deeply influenced by Wu Changshuo. He paints branches with dignified stones and likes to use strong magenta when ordering flowers. The former residence of historian Chen in Sun Yat-sen University Park is called "Cold Willow Pavilion" by the world. Chen Yinque has a soft spot for cold willows. The collection of essays is called Han Liu Tang Collection, and the collection of poems is a manuscript of Han Liu Tang's poems. His own family history is that Han Liu Tang dreamed. After textual research, Chen Yinque has a soft spot for cold willow, which is probably related to his special feelings for Liu, a poetess in the late Ming Dynasty. Liu's thought and behavior of maintaining the spirit of national culture are consistent with Chen Yinque's idea of not forgetting his national identity, which makes him and Liu become bosom friends through time and space. Mr. Hu Shouwei believes that this is the cultural motivation for Chen Yinque to write his own unique biography of Liu after ten years of poverty. Chen once laughed at himself and said, "I gave up my life for righteousness, only looked down on my eyes, and only left red makeup in the book." Liu's "Jin Ming Chi Han Liu Fu" was praised by Chen as "the first poem in the late Ming Dynasty". It can be said that Lengliu is the embodiment and portrayal of Liu.

There are three pine trees in the courtyard where the philosopher Feng Youlan lives. In his later years, he named his lifelong work The Complete Works of Sansongtang. Feng Youlan explained the reason for the naming: three pines in the court, touching and lingering, more profound and far-reaching These three trees accompany Mr. Feng day and night. When he is cold, he knows that the pine and cypress are dying, which can be regarded as the symbol of his supreme personality.

Liang Shiqiu loves grass, flowers and maple trees, so the elegant houses he left behind include Aifeng Tree and Rhododendron Mountain. In Mourning for the Maple Tree, he said affectionately: Maple provides us with shade when we need it. In winter, when we need warmth, it quickly removes its thick leaves, leaving only bare branches and claws in the cold air. It's so funny, so cute!

When Yu Pingbo, a red scientist, first entered Beiping, he took Guhuai Bookstore as the name of Zhai because there were ancient pagodas in the courtyard. He also wrote three books in the name of the bookstore: Dream of Ancient Huais, Ci of Ancient Huais Bookstore and Dream of Wu Huais. Every time someone asks about the locust tree, Mr. Yu closes his eyes and pays close attention. He replied for a long time: this tree is older than this house and has read all the vicissitudes of life. This scene here has become one of the marks of his life in Beiping.

When the poet Hu Feng came to Beijing in the early days of the founding of New China, he planted four trees in his yard: a pear tree, a peach tree, an apricot tree and a clove tree. Therefore, he named his study Si Shu Zhai, and later signed the four study Hu Feng at the end of all articles. Who knows this is exactly what I said. He said with emotion: what four-tree lent? I made enemies all around!

There are two towering poplars in the former residence of Mao Dun in Beijing, which echo with the writer's masterpiece Praise of Poplar and become an indispensable and important landscape and symbol. Mao Dun also wrote a poem: There are beautiful trees standing like spears in the north. All leaves are United, and branches strive for the upper reaches. It is difficult to be ashamed, but willing to live in algae. Dan Qing is a man of backbone and is willing to share hatred with his son.
