凤城满族自治县大堡镇大堡村村民李世国,1984年在1.2 亩的庭院里建立一个巨峰葡萄园。由于他科学管理,第二年亩产近600公斤,第三年亩产1,800公斤,最高株产20公斤。他获得葡萄早期丰产的主要经验有以下几点。一是采用催根育苗技术。定植前一个多月,将头年冬剪时选留的插条(拐子)插入沙箱中,放在火炕上催根育苗。箱内沙子要保持湿润,沙箱底部温度保持28—30℃,经1个月左右,插条即可生根发枝。然后逐渐降低温度进行炼苗,经10天左右炼苗后定植在院内。幼苗定植后成活率高,缓苗快,当年主蔓可生长2米左右。
Li Shiguo, a villager in Da Bao, Fengcheng Manchu Autonomous County, founded a giant vineyard in 1984 in a 1.2-acre courtyard. Because of his scientific management, the second year, nearly 600 kg per mu, the third year 1,800 kg per mu, the highest strain of 20 kg. His main experience with early grapes harvesting is as follows. First, the use of root nursery technology. More than a month before planting, the first year of winter cut when selected cuttings inserted (sandwiches) into the sand box, on the kang root reminder nursery. Sand inside the box to keep moist, sand bottom temperature maintained at 28-30 ℃, after about 1 month, cuttings can take root branch. Then gradually reduce the temperature for hardening, after about 10 days colonization after planting in the hospital. After planting seedlings high survival rate, Huanmiao fast, when the main man grows about 2 meters.
