Cherry is the first fruit in the spring in the northern deciduous fruit trees. It is bright and colorful, delicious, nutritious, and has the reputation of “the first branch of the spring fruit” and the “treasure in the fruit”. Cherry fruit contains rich nutrients, has the role of adjusting the spleen, regulating Qi and activating blood circulation, and removing liver heat. It is a kind of health-care fruit that prolongs life, and is called “vitamin pill” by experts [1-2]. Big cherries are the fruit tree species in Laizhou, which are currently cultivated in large areas. They have less management labor, low production costs, and high economic benefits. The current cherry cultivation techniques are summarized below.
1 The joy of building a garden cherry is to choose a hilly land with fertile soil, deep soil layer, low groundwater level, well-drained water, and water-filled conditions. Soil requirements are neutral or acidic sandy loam or loam and require open terrain, good light conditions, and air circulation. If a park is built in the plain, windbreaks or windbreaks should be planted on the north side of the orchard to prevent winds from warming. The early maturing varieties include red light, Italian early red, early big fruit, and early morning, etc. The medium-maturing varieties mainly include Nageng, Saitengjin, and Pioneer, and the late-maturing varieties include Sunyang and Rennie. When selecting pollination varieties, it is necessary to consider various factors such as high pollination affinity, main flowering period, strong adaptability, and high fruit economic value of the main plant varieties, and it is best to select more than two pollination varieties. The percentage of pollination trees should be above 30%.
2 The seedling planting cherry has the highest survival rate in the middle and late March. The row spacing can be 4 m × 5 m or 5 m × 6 m. Different regions can adjust the row spacing according to the soil fertility and the growth potential of the varieties. Plant the seedlings to extend the roots, cover the soil to the seedlings when the seedlings are in the original nursery, fill in the soil and then apply water and water. After the water infiltrates, use the soil to seal the hole and cultivate a 30 cm high mound to facilitate the preservation of the soil. Moisture [3]. Ploughing the whole garden in autumn or early winter before planting, and applying high-quality fertilizer 75-150 t/hm2 according to soil fertility to improve the soil.
3 Soil Fertilizer Water Management Cherries are shallow rooted trees and require strict soil conditions. When planting, the hole communicates with the ditch so that the root system can be stretched to prevent it from accumulating inside the hole. In the second year, combined with Shiji, digging 60 cm wide and deep trenches between the plants to make the ditch penetrated and communicated with the original planting hole. For a cherry orchard planted with a ditch and planted along a ditch, the ditch with a width of 1 m and a depth of 60 cm should be excavated between the plants, and a ditch with a width of 1 m and a depth of 60 cm should be excavated between the rows in the third year. The garden has reached a 40 cm thick layer of living soil. From the time of colonization, a mound of about 30 cm high was cultivated at the base of the trunk. Planting 0.5 to 1.0 kg/strain of ternary or multi-component fertilizer from June to July in the year of planting. 2 to 3 years for the crown expansion period of the young tree, with the application of quick-acting nitrogen fertilizer, supplemented with appropriate amount of phosphate fertilizer, promote the early formation of crown; 4 to 6 years for the initial result period, the application of organic fertilizer and compound fertilizer as the main control Nitrogen, phosphorus, and potassium supplements are mainly applied to the base fertilizers and pre-harvest topdressing before autumn; 7 years or more is the result of the peak period. In addition to autumn base fertilizers and top dressings before flowering, attention should be paid to top dressing and nitrogenous fertilizers after fruit harvesting to prevent trees. Excessive body and premature aging. Autumn basal fertilization should be carried out from September to November. The application of topdressing nitrogen fertilizer at the early flowering stage has a significant effect on promoting flowering, fruit setting and foliage growth [4]. Spraying 0.3% urea + 0.1% -0.2% borax + 600 times potassium dihydrogen phosphate solution at full flowering stage can effectively increase fruit setting rate and increase yield. About 10 days after fruit picking, the shoots stopped growing and the flower buds started to diverge. At this time, fertilizer should be applied immediately, preferably compound fertilizer. Before germination to flowering, the water before flowering is the germinating water, so as to avoid the harm of the late frost and effectively increase the leaf area and facilitate the formation of flower buds. After the flower is dropped, if the size of the fruit is sorghum, the hard core water should be poured and the irrigation should be sufficient. That is to say, water should be poured 1 time before harvest and the water should be controlled before 10 days before harvest to ensure the fruit quality. After harvesting, the flower buds are differentiated and concentrated, and fertilizer and watering should be applied immediately. 4 Fruit and Fruit Management Cherry has a low self-cultivation ability. In addition to disposing pollination trees when setting up the garden, artificial pollination (rolling on a feather duster) and pollination with pollinators should also be performed. Sparse blossoms are carried out before flowering or flowering of large cherry. Generally, 5 to 7 flower buds of short flowering branches can fade away about 3 weak flower buds, retain 2 to 4 full flower buds, and retain flower buds to open about 3 flowers. Each flower-like fruit branch retains 5 to 7 flowers. After the fruit is naturally dropped, the fruit is thinned, leaving 3 to 4 fruits per short bunch of fruit. Remove small fruits, weak fruits, and fruits that are not easily colored, and retain horizontal and upward large fruits. When a fruit matures, it often attracts birds to feed. Birds should be guarded against birds, and the method of spreading the net is usually adopted.
5 Pruning The cherries should not be too dry, generally 60 to 80 cm. The concentrated seedlings are taken as short cuts to give them a “stick”. The young cherry tree grows particularly vigorously and has natural growth levels. The degree of summer pruning should not be too large. Sparse branches, thin and weak branches, and dead branches of the pests should be removed or shortened to retain a certain length. In principle, the stem does not move, but when the lateral shoot grows to 50 to 60 cm, the opposite shoot can be picked slightly. Winter pruning should not be carried out prematurely, and it is usually implemented after the beginning of spring. In the winter, the mid-dry height is determined by a short cut, and the sprouting around the middle dry twigs achieves the requirement and purpose of promoting the branches and cultivating numerous fruiting branches. The pruning of dried stems is heavier than that of apples and is in a controlled state to facilitate the germination of lateral branches.
6 Pest control During winter pruning, do a clean garden work and spray it with 5 ° Bé lime sulfur before germination. When spring shoots are taken (around June 10), thiophanate-methyl, carbendazim, Dasheng M-45, mancozeb, and other sprays can be selected to prevent diseases. In late June and late July, each sprayed 200 times the lime times Bordeaux mixture, spraying 2 or 3 times a year. Insect pests mainly prevent red spiders and white spiders, paying attention to the green-blind maggots, leaf miners, moths, etc., as well as the moth-eaten leaf-feeding leaf-feeding leaf pests, which can be used as 3,000 times as much as 20% cypermethrin EC. Liquid, or 2.5% to 2.5% of deltamethrin spray control. In addition, it can also be controlled by chlorsulfuron, imidacloprid, abamectin, diflubenzuron, and the like.
7 Fruit Harvest The cherry fruit is poor in storage and transportation, and it is not resistant to mechanical operations. Therefore, it mainly depends on manual picking. When picking, holding the fruit stems, with the index finger to withstand the base of the pedicel, gently lift off to pick. During the picking process, care must be taken with care to avoid man-made injuries, and at the same time, good results should be taken to ensure good results.
