The cherry spring tube was
"Cherry's delicious tree is hard to plant." How about the cherry tree planted in the spring when cherry is planted in spring? What diseases need to be controlled? Recently, the reporter interviewed a senior fruit technician named Zhong Zhongfu of the Zhuangfu Fruit Planting Professional Cooperative in Tianfu New District, Chengdu, Sichuan Province. He told the reporter that the management of cherry is one of the fruit trees that the fruit growers prefer to plant, and it is actively developing cherry. The industry has a bright future.
Planting environment
Cherry is a happy, happy, happy, fruity tree. It is suitable for growing at an annual average temperature of 10 to 12 degrees, an annual rainfall of 600 to 700 mm, and annual sunshine hours of 2600 to 2800 hours.
Key technologies
Cherry is suitable for planting in November and March of the following year. 111 acres of planting, spacing 23 meters.
1. Before planting, first remove the grafted membrane from the graft and trim the length of the main root and the long lateral root at 15 cm. Seedlings should be soaked in fresh water for 1 to 2 hours depending on the water loss. At the time of colonization, the pruned seedlings were stained with a sufficient amount of mud or aqueous solution mixed with rooting powder and carbendazim to sterilize and promote seedling survival.
2, planting, in the pre-established position on the first soil loose pine 50cm square soil for 10cm deep hole, the roots of the seedlings flattened in the planting hole system around, with fine soil to root tightly stepped tight. Pouring enough water to soak the rooting water. It is advisable to pour about 20 pounds of water per plant. From the soil to seedlings in the soil mark of the nursery, the grafting interface is exposed outside the soil. Then cover a black plastic film 1 m square, surrounded by sealing, warming and moisturizing, and promote the growth of seedlings.
Fertilizer management
(1) Sapling fertilization principle: The plant should be applied in a thin manner, and timely fertilization and top-dressing of foliar fertilizers should be used to make the young trees grow neatly and robustly, and early high-yield. When the new shoot grows to 15 to 20 centimeters, fertilizer is applied in time. Every 100 pounds of water is added 3 two urea 5 two superphosphate stir evenly after pouring, the plant applies 3 to 5 pounds of fertilizer water is appropriate. Before July, nitrogen fertilizer was the main form, applied once every 15 days or so, a total of 3 to 4 times were pursued, and weak plants should be topped with 2 or 3 more times to make the weak plants catch up with the strong trees as soon as possible.
(2) The second year of tree fertilization will be applied once in the second, third, ninth and October. In February and March fertilization, 50 cm from the main stem of the fruit seedlings were planted, and three small pits were drilled. The compound fertilizer (N, P, K15:15:15) was applied to the plant at 50 g and the soil was covered with water. During the use of fertilizers, it must be applied lightly and hard to avoid excessive use of fertilizers, causing burning of roots and burning seedlings.
Disease prevention and treatment
Cherry brown rot mainly damages flowers and fruits, causing flower rots and fruit rots. At the early stage of disease, the flower grows gradually brown until it is dry. Prevention and control measures: Clean the orchard, sweep away the fallen leaves and fruit and burn it; reasonably trim, make the canopy have good ventilation and light conditions; spray 3 to 5 degrees lime sulfur before germination; spray once every 10 to 15 days in the growing season Drugs, spray a total of 4 to 6 times, the agent can be used 1:2:240 times Bordeaux mixture or 77% can kill 500 times, 50% captan 500 times.
Cherry flow gum disease mainly damages cherry trunks and main branches. It usually begins when the sap flows in the spring, resulting in declining tree vigor, and branches are dead when severe. Prevention and control measures: Increase organic fertilizers, strengthen tree vigor, prevent drought, aphid, and freezing injury; do a good job of prevention and control of pests and diseases to avoid causing excessive wounds; and find out that fluidic diseases must be promptly scraped and then coated with drugs for protection. The commonly used agents include 50% tetromycin, 50% suspended sulfur, 5 portions of water, and a mixture of water, and 10 parts of quicklime, 1 part of lime sulfur, 2 parts of salt, and 0.3 parts of vegetable oil.
