Large flat apricot is an excellent tree species for village and township greening
Large flat apricot is a plant of the genus Prunus in the Rosaceae family and is an economic tree species unique to our country, originating from the Zhangjiakou area of Hebei Province and the suburbs of Beijing. In 2002, Liaozhong County of Shenyang City introduced nearly ten thousand large flat apricot seedlings for trial planting, and since 2006 has carried out large-scale promotion and cultivation; at present, the whole county has planted nearly 2000 mu of large flat apricot, and the growth is good. The excellent characteristics of large flat apricot: strong adaptability: cold-resistant and drought-resistant, tolerant of barren soil. It can grow normally whether in plains, mountains, hills, or sandy, barren, saline-alkali land. Early fruiting and high yield. Long fruiting period: two to three years after planting

Scraping pear tree bark in winter is the key to growing good pears
The farming proverb says: "If you want to eat good pears, scrape the bark in winter." In the cold winter season, scraping off the old bark of pear trees that have already borne fruit can effectively eliminate fungal spores such as pear scab, ring rot, anthracnose, and pear rust that remain inside and outside the old cracked bark of pear trees, as well as the eggs of various pear tree pests such as the pear psyllid, aphids, fruit borers, and scale insects, ensuring robust production of pear trees with high quality, high yield, and high returns. Scraping must be thorough When scraping pear tree bark, you must remove the old cracked bark, rot disease, pear scab, ring rot, anthracnose, scale insects, pear psyllids, aphids,

The Pathogenesis and Control Methods of Peach Tree Gummosis
Peach tree gummosis is a disease commonly occurring on peach trees today, and its incidence is severe. Especially in peach orchards with extensive management and weakened tree vigor, the rate of affected plants can reach over 90%. This disease severely weakens tree vigor, affects yield and quality, and in severe cases leads to dead branches and dead trees, threatening the production and development of peach trees. It is also one of the most troublesome diseases for fruit growers. I. Causes of peach gummosis. There are two causes of peach gummosis: one is non-infectious pathogens, such as gummosis caused by wounds from mechanical injury, pest and disease damage, frost damage, freeze injury, etc., or gummosis caused by physiological disorders of the tree body resulting from extensive management

How to prevent and treat gummosis in peach trees? A detailed guide to practical methods
Peach gummosis is a physiological disease that occurs frequently on peach trees, mainly on the branches and trunk, and in severe cases it has a great impact on the growth and development of the peach tree. Besides peach, stone fruit trees such as apricot, plum, Japanese apricot (ume) and cherry also suffer from it. Symptoms of damage: This disease can occur on any part of the peach tree's branches and shoots. The diseased part swells slightly, the wood tissue turns brown, and then a transparent gum-like substance oozes from the lenticels or wounds; after contact with air it gradually turns yellowish-brown to brown, and finally becomes a black hard lump. The bark of the diseased part is rough and cracked, heals with difficulty, and easily becomes an egg-laying site for the red-necked longhorn

Detailed Explanation of Key Points of Jujube Tree Training and Pruning Techniques
The training and pruning of jujube trees is based on the jujube tree's unique branching habits and its strong light-loving characteristics. Through pruning, a fixed framework suitable for the jujube tree's growth habits is formed, thereby improving the transparency of the canopy, increasing the fruiting positions, achieving three-dimensional fruiting, improving jujube fruit quality and yield, and extending the fruiting years. There is no issue of retaining flower buds: the flower buds of most fruit trees are differentiated in the previous year, so during winter pruning the number of flower buds to retain must be determined according to the target yield, in order to reduce the consumption of large amounts of tree nutrients caused by flowering and fruit set.

What meteorological factors does jujube tree growth require?
Germination stage: when the daily average temperature reaches 13--14°C, germination begins; at 17°C, leaves unfold. Flowering stage: when the daily average temperature reaches 19--20°C, flower buds appear, and at 20--22°C flowering begins. During full bloom, the optimal temperature is 22--27°C and the relative humidity is 60%--70%. A relative humidity below 25% will cause a large amount of "scorched flowers" and young fruit drop. Fruit ripening stage: the optimal temperature for fruit development is 25--27°C, with relative humidity around 75%. Optimal temperature during the fruit ripening stage 1

The giant winter peach is a new variety among peach trees.
The "King of Chinese Peaches," the "Giant Winter Peach," is the latest new and superior winter peach variety bred by the Zhengzhou Fruit Research Institute of the Chinese Academy of Agricultural Sciences. Its outstanding characteristics are as follows: exceptionally large fruit. The average single fruit weighs more than 400 grams, and the largest single fruit reaches 1200 grams. The fruit is nearly round and is one of the largest peach varieties currently in China. The appearance is brilliant and the quality is excellent. After ripening, the fruit fuzz naturally falls off; the background color of the fruit surface is creamy yellow, and the fruit surface is bright red, very brilliant, in line with internationally popular colors; the flesh is milky white, the texture is dense, tender and firm, and the taste is sweet with a delicate fragrance, with a sugar content of 17

Detailed Guide to Peach Tree Cultivation Techniques and Key Planting Management Points
Peach trees generally come into production in the third year and reach full production in the fourth year. After reaching full production, the yield is 3500 jin per mu, the annual input is 1000 yuan (including 400 yuan for land rent), the output value per mu is 5200 yuan, and the profit is 4200 yuan per mu. The main varieties and cultivation techniques are as follows:

What are the control methods for the jujube tree tortoise wax scale?
(1) Manual removal of the pest source: during winter and in early spring in March of the following year, use a stiff-bristled brush to scrape the insects off the branches and collect and kill them. If snow or fog freezes on the branches with a thick layer of ice, you can directly strike the branches to shake off the ice, and the insects will fall with it. (2) Protect and utilize natural enemy resources: this pest has many natural enemies; a single predatory Chilocorus kuwanae can prey on thousands of these insects in its lifetime; the larvae of the long-shield golden small wasp can parasitize under the pest's abdomen and feed on the scale eggs. The larvae of the long-shield golden small wasp can parasitize under the pest's abdomen and feed on the scale eggs. (3) Chemical control:
