大蒜是成县栽培历史悠久、营养丰富、风味独特、用途广泛、发展较快、市场畅销、收益较高的名优外销商品蔬菜之一,近几年播种面积、产量、产值均占到全县蔬菜生产的三分之一以上。但近年来,成县大蒜由于长期进行无性繁殖,受多种病毒的连年侵染,使品种逐渐衰老退化,加之新技术研究应用滞后,栽培管理不当,致使品质变劣,产量下降,效益徘徊。本县农技人员通过近3～4年的试验探索,总结出了一套地膜大蒜高产、高效技术规程,可有效消除
Garlic is one of the famous export commodities vegetables with long history, rich nutrition, unique flavor, wide range of uses, rapid development, best-selling market and high income in the county. In recent years, the planting area, output and output all account for vegetables More than one-third of production. However, in recent years, due to long-term vegetative propagation in Chengxian County, successive years of infection by many viruses have led to the gradual deterioration of cultivars. In addition, the application of new technologies lags behind and the cultivation and management are inadequate, leading to deterioration in quality, yield decline and profitability. The county agricultural technicians through nearly 3 to 4 years of experimental exploration, summed up a set of high yield garlic film, high efficiency technical regulations, which can be effectively eliminated
