用石灰氮打破棚室葡萄的休眠期,以提早上市,这项技术已成为葡萄设施栽培中不可缺少的关键技术,在我国已应用近十年,越来越被广大农户所认可。但是由于石灰氮呈粉尘状,电石味很浓,对人畜的鼻粘膜有较强的刺激,所以无论是小包装,还是在葡萄上喷涂都不方便。因此笔者于2000年初在盖州市红旗镇八家村的无核白鸡心葡萄上,进行了用单氰胺来打破葡萄休眠的试验,收到良好效果。
Lime nitrogen to break the dormant period of greenhouse grape to be marketed earlier, this technology has become an indispensable key technology in grape cultivation in our country has been applied for nearly 10 years, more and more farmers are recognized. However, since the lime nitrogen is dusty and the calcium carbide is very strong, it has strong stimulation to human and animal nasal mucosa, so it is inconvenient to spray on small grapes or grapes. Therefore, in early 2000, the author carried out the experiment of breaking dormancy of grape with cyanamide on the grapes of seedless white chicken hearts of Bajian Village, Hongqi Town, Gaizhou, and received good results.
