Prunus armeniaca is usually grafted with Prunus armeniaca as rootstock, and there are two methods of grafting: branch grafting and bud grafting. Grafting of branches should be carried out in spring, and bud grafting should generally be carried out in early August. Select the fully developed branches and buds of the year and graft them with the buds.

The planting density of Prunus armeniaca is per hectare 1245 plants, and the row spacing is 2× 4m. The best planting time is digging holes in summer and autumn, preserving rain and snow, and planting in spring. During the growth of young trees, it is necessary to strengthen management, prune in time, loosen the soil and fertilize, and prevent and control pests and diseases in time. In mountain apricot orchards, the combination of grass mulching under trees and topdressing with chemical fertilizers can promote the formation of humus under tree crowns, improve soil fertility and ensure high and stable yield of apricot orchards.

Prunus armeniaca has strong adaptability, fast growth and early fruiting, and is one of the precious local products. The apricot garden is well managed, with considerable economic benefits, and the income per mu is 1000 yuan.

Due to the limited information on hand, please go to the local agricultural science and technology exhibition hall or library to consult relevant information, and now provide some reference books.

Prunus armeniaca is a unique resource in China, which is barren-tolerant and adaptable. Almond is rich in nutrients and anticancer substances, and enjoys a high reputation in the international market. Since March, 2003, our county has selected 23 small watersheds in Weizigou, Dasijiazi in the east, Houxinqiu and Sihecheng in the north. Focus on the implementation of small watershed soil and water conservation comprehensive management demonstration pilot project. In the control area1.5000 hm ~ 2, we chose sloping farmland1.333 hm ~ 2 and wasteland1.000 hm ~ 2 to plant Prunus armeniaca. By the time of acceptance in April 2006, the forest and grass coverage rate of the sample plot had reached 10%, and the annual water storage capacity was 47. Soil and water conservation 1.6 million t, per capita income 1.30 yuan. It is estimated that by 20 10, the economic benefit of Prunus armeniaca will reach10.5 million yuan, the social benefit will be doubled, and the ecological environment will be comprehensively improved. The soil and water conservation measures and under-forest cultivation management techniques of apricot orchards in mountainous areas are summarized as follows.

According to the research results and production practice of apricot, the reasons for the low fruit setting rate of apricot were summarized, and the comprehensive technical measures to improve the fruit setting rate of apricot were put forward, such as selecting excellent strains, configuring pollination trees, shaping and pruning, flower and fruit management and underground management.

First, the superior trees of Prunus armeniaca were selected, and then the superior trees were identified. According to the main productive and economic characters of the clones, five excellent apricot clones, 90 18, 9037, 9063, 9076, 90 106, were selected by principal component analysis. The selected excellent clones are genetically stable in high yield and economic characters, and the yield is high and stable.

Since 1990, we have undertaken the key scientific and technological research project of Liaoning Science and Technology Commission, "Study on Selection and Breeding of Improved Varieties of Prunus armeniaca". After 10 years of selection of superior trees and identification of superior clones, we have bred an excellent apricot strain (Longwangmao) with cold resistance, drought resistance, high and stable yield, big kernel and high quality.

Prunus armeniaca is a specialty of Rosaceae. Almonds are large and flat, with good quality. Its almonds contain 60% fat, 23% protein and 65,438+00% sugar. It also contains trace elements such as phosphorus, calcium, iron and potassium, 18 amino acid and anti-cancer substance vitamin B 17, and is used in food and medicine. It is a precious local product and a "fist commodity" of China's foreign trade export. Prunus armeniaca is one of the main economic tree species in northern China, which has the characteristics of fast growth, early fruiting, high yield and long economic life. With the adjustment of forestry production structure and the rise of "green enterprises", the planting area of Prunus armeniaca has developed rapidly on the original basis. At present, there are 20,000 hectares of Prunus armeniaca, about 30 million plants in our province. Some apricot orchards grow slowly. Low yield and poor benefit have formed a low-yield orchard. In order to speed up the base construction and realize the goal of "two highs and one excellent" in apricot production, it is necessary to transform the low-yield garden.
