自1980年秋开始,我们在立新区恩山岭公社恩山岭大队等三个试验点,利用日光照塑料温室进行葡萄一年三收的栽培试验,证明这种栽培方法可使葡萄全年采收期长达120多天。栽植第二年3次结果,平均亩产8,000斤以上。另外,温室葡萄可在架上安全越冬,解决了防寒、上架问题,与露地栽培相比经济效益显著提高。
Since the autumn of 1980, we conducted three-year cultivation experiments on grapes using sunlight-plastic greenhouse in the three test sites of Nanshanling Brigade in Nanshanling commune of Lixin District, which proved that this cultivation method can make grapes long-term harvesting period Up to 120 days. Planted three times the second year results, the average yield of 8,000 pounds or more. In addition, the greenhouse grape in the shelves safe wintering, to solve the cold, shelves problem, compared with open field cultivation significantly increased economic efficiency.
