A good Tree species for Village Greening-Dabian Apricot

Dabian apricot, a plant of the subgenus Prunus of Rosaceae, is an endemic economic tree species in China. It is native to Zhangjiakou area of Hebei Province and the suburbs of Beijing. In 2002, nearly ten thousand seedlings of Dabian apricot were introduced into Liaozhong County of Shenyang City for trial planting, and a large area of popularization and cultivation has been carried out since 2006. at present, Dabian apricot has been planted in the county of nearly 2000 mu, and growing well. Dabian apricot has excellent characteristics and strong adaptability: cold and drought resistance, barren resistance. It can grow normally in plains, mountains, hills and sandy saline-alkali land. Early fruit and high yield. The result period is long: it can bear fruit after two or three years of planting, and the fourth to the fifth year enters the full fruit period, and the full fruit period lasts as long as 50-60 years, and the apricot fruit yield per mu can reach 1500 kg. Fruit listed early: it can be harvested and listed at the end of May every year, which is the off-season of the fruit market and plays a very important role in regulating the supply of fresh fruit market in early summer. Its price can reach about 8 yuan per kilogram. Fruit has a wide range of uses: in addition to fresh food, apricot fruit can also be processed into preserved apricot, dried apricot, apricot juice, canned apricot and so on. Almonds can not only be processed into almond cream, almond dew and all kinds of cakes and candies, but also have medicinal value, such as invigorating body and relieving thirst, moistening lung and resolving phlegm, clearing heat and detoxification, treating wind-cold lung disease and so on. In addition, the almond oil extracted from almonds is a kind of advanced industrial lubricating oil and an important raw material for many high-quality cosmetics. High nutritional value: the content of carotene b in apricot fruit is 2.2 times of Hawthorn, 22.4 times of apple, 30 times of peach, 179 times of pear and nearly 400 times of citrus. The fatty acids contained in almonds are also very beneficial to human health. Apricot also contains calcium, phosphorus, iron, potassium, sodium and other trace elements and various vitamins and proteins, fats and sugars and other nutrients. Planting method planting density: for Dabian apricot orchard with good site conditions, it is suitable to plant 55 trees per mu. In places with poor site conditions, 83 plants can also be planted per mu. Village greening planting large flat apricot, the plant distance of 3 meters to 5 meters is appropriate, street, road, road greening should be more than 6 meters. Planting method: take the planting site as the center and dig a planting pit with a diameter of 50 cm and a depth of 40 cm. If farm manure is applied, the pit depth and diameter will be larger. The soil dung should be mixed well with the ripe soil. The night before planting, the roots of the seedlings were cut, the grafted plastic strips were untied, and the roots were soaked in water in a small pit dug in advance, so that the seedlings could fully absorb water. When planting, first pour water into the pit, add a little soil, mix it into mud, put the seedlings into the pit, fill the seedlings and step on them again and again. Finally, according to the size of the planting pit, a 20 cm high mound was formed at the base of the seedling to prevent soil moisture from evaporating. When planting seedlings, the planting depth should be strictly controlled, and the rhizome of the seedlings should be slightly lower than the surface. The management fixed stem after planting: the fixed dry height is 70 cm-80 cm. Cut off the upper part with pruning shears, and there must be full buds under the cut. Timely drying can reduce water evaporation of seedlings, prevent wind shaking, maintain the balance between underground and aboveground parts, and is conducive to survival and growth. Irrigation: about 15 days after planting, if the soil is dry, slow seedling water should be irrigated once in the soil pile, and the amount of irrigation should not be too much. After irrigation, it should be sealed and buried into a small mound. Remove the mound and sprout: remove the mound at the base of the seedling when the seedling leaves, so as to increase the soil temperature and air circulation, promote the development of roots and the growth of aboveground parts. At the same time, wipe off the sprouts of the seedlings 40 centimeters below the ground. Whitening: build a pile of soil in the rhizome before freezing, and at the same time paint the tree cadres with white ash to prevent disease and cold of young trees. The development of Dabian apricot can conserve soil and water, afforest the "four sides", increase the green coverage rate and improve the ecological environment. Moreover, Dabian apricot is resistant to drought and barren, strong adaptability, easy to manage, resistant to storage and transportation, and high economic value, so it is called "iron crop". It is the first choice for farmers to shake off poverty and become well-off and beautify their homes.
