Almond (Ren Peach, American Almond) is the most important tree species in the international fruit trade, with high economic benefits. In the international market, the price of unprocessed almonds is about 4,000 US dollars / t, and the price of finished almonds is about 2 times its price. In the United States, the cultivation and production of almonds has become an industry. The almonds develop fast and the results are early. The tree grows into the fruiting stage in 3 to 4 years. The fruiting period is 10 to 25 years. The economic life span is 50 years. The fruit yield can reach 150-300kg/667 square meters, plus almonds. It is a fast-growing tree species, so it is the best choice for returning farmland to forests.
1 The choice of almonds is resistant to barren, drought-tolerant, cold-resistant and highly adaptable. However, in the production, it is best to choose loam and sandy loam with deep soil and good ventilation. Since almonds are extremely vulnerable to night frost, it is necessary to pay attention to the selection of the central slopes and the open flats, valleys and sheltered south slopes, and be careful not to build gardens on the windward side of the main wind direction. 
2 The row spacing of seedling plants should be 3m×4m or 4m×5m, and the planting density is 33～35 plants/667 square meters. In order to achieve the goal of high yield and high efficiency in the early stage, 83 to 111 plants/667 square meters can be planted for the planned dense planting, but attention should be paid to timely thinning. The planting seedlings can be used for both finished seedlings and sprouts. The use of bud seedlings can save 1 year of seedling time, which is convenient for early plastic surgery, but some reserve seedlings need to be kept, which is convenient for replanting at any time. Planting pits with a depth of 60 cm and a diameter of 60 cm before planting can be directly dig into a planting belt of 60 cm wide and deep. 
3 Fertilizer management young trees are applied once a year, and adult trees are applied once every 2 to 3 years. The saplings are applied with 15 to 25 kg of base fertilizer, 20 to 25 kg for middle-aged trees, and 50 to 100 kg for large trees. Fertilization in a year is generally divided into 3 times. The first time should be in early spring or autumn and winter, with quick-acting nitrogen fertilizer as the main. The second time is in the fruit expansion period, mainly nitrogen and potassium fertilizer, and the third time after fruit harvesting, composting. Organic fertilizers such as manure and fertilizer are mainly used in combination with deep turf in autumn. In addition, foliar spray fertilizer can also be carried out during the growing season, such as 0.3% potassium dihydrogen phosphate, 0.2% to 0.4% urea, and the like. In areas with annual rainfall of 400-450 mm, there is generally no need to special watering. In areas with insufficient rain or uneven distribution in summer, water should be irrigated 1 or 2 times. If you do winter irrigation before winter, the effect is better. 
4 Plastic trimming almonds are light and dry. In high-density cultivation orchards, they are mainly free-spindle-shaped, and low-density orchards are mainly natural and happy. The main feature of the free spindle shape is that there is a central leading trunk. In the different parts of the center, 10 to 15 main branches are left in the wrong place. The main branch and the trunk maintain an angle of 80 to 90 degrees, and the result branches are directly formed on the main branch. The main feature of the natural happy shape is good light transmission, dry height 40 ~ 50cm, choose 3 to 4 main branches on the trunk, base angle 45 ~ 70, 2 ~ 4 side branches, equipped with branches on the side branches. Because the almonds are strong, the principle of pruning is to reduce the number of cuts. Almonds are mainly caused by short fruit branches. The saplings and fruit trees grow vigorously in the early fruiting stage. The amount of medium and long fruit branches is more. Generally, when the new shoots grow to about 50-60cm, the heart is picked up in time, the secondary shoots are promoted, and the result branches are increased. At the same time, the excess branches are removed in time. For the branches and erect branches that have space to be retained, when they are as long as 50 to 60 cm, twist them in time. It is basically not cut in winter, and it can be formed in the winter of the second year after planting. 
5 flower and fruit management
5.1 Strengthen the comprehensive management of orchard to apply organic fertilizer, enhance the tree potential, promote flower bud differentiation, and pay attention to the combination of nitrogen, phosphorus and potassium fertilizer, which is beneficial to increase the ratio of complete flower, thus reducing the drop of flowers and fruits. 
5.2 In the flowering period, the amygdala flowers are worm flowers, and the bees are placed in the flowering period. Generally, 1 box of bees per 667 square meters can be used to make the normal flowers get good pollination and fertilization, thereby increasing the fruit setting rate and increasing the yield by 20%. 
5.3 Reasonable allocation of pollination tree almonds are not self-sufficient, generally every 2 to 3 rows of main varieties, with 1 to 2 rows of pollination varieties, creating conditions for the normal pollination and fertilization of almonds, which is conducive to improving the fruit setting rate. At present, the main reason for the low fruit set rate and low yield of some new almond bases in China is due to the unreasonable allocation of pollination trees. When constructing a garden, we must pay attention to the allocation of pollination trees. When the varieties are matched, the main varieties should be combined with an early flower variety and a late flower variety. For example, Yiyiping No. 1 is the main plant variety, accounting for 60%. Ping 2 and Yiping 3 are pollinated tree varieties, each accounting for about 20%. 
6 Pest control The almonds have strong resistance to pests and diseases. The main factors affecting the growth and development of almonds are peach aphids, red spiders and leaf shrinking diseases, dry rot, root rot, and gum disease. (1) Controlling peach aphids. In addition to the control of natural enemies such as grasshoppers and buds, it can be controlled with 40% dimethoate or 50% dichlorvos or 50% parathion 2000 times. (2) Controlling red spiders. Can be used to prevent death or phlegm. (3) Prevention and treatment of leaf shrinkage. Spray with 50% thiophanate 800-1000 times solution or defoliation with Baume 5 degree stone sulphur mixture. (4) Prevention and treatment of dry rot. Brush the disease with a 4 degree stone sulphur mixture. (5) Prevention and treatment of root rot disease. The topsoil is removed from the roots of the tree and the upper rhizome is exposed to the air and dried. (6) Prevention and treatment of gum disease. After the flower, spray a 0.5 degree stone sulfur mixture every 15 to 20 days for a total of 3 times. It can also be sprayed from the month of April with 50% carbendazim wettable powder 1000 times, and sprayed once every half month for 3 to 4 times.
