当前人参生产上存在的主要問題是:病害严重,品种混杂,产量不高。在老参区一般因病害减产30%以上,新栽参区病害也相当严重。看来,通过杂交育种的途径,选育出抗病、丰产、优质的新品种,是进一步提高产量和质量的主要关鍵之一。但杂交之前,必須詳細研究人参开花习性及杂交技术,才能順利开展工作。为此,作者于1960年、1962年进行了試驗观察,現将結果报道如下。材料及方法本試驗以吉林省农家品种大馬牙(3～5年生)作材料,1960年在吉林省特产研究所(左家地区),分别于田間参畦中檐,选定植株,进行出苗至始花期所需天数,一昼夜开花情况,单花序、单花朵开花情况的观察;又以同样材料、方
At present, the main problems in the production of ginseng are: serious diseases, mixed varieties, and low yields. In the old ginseng area, the disease is generally reduced by more than 30% due to diseases, and the diseases in the newly planted areas are also very serious. It seems that through cross-breeding methods, the selection of new disease-resistant, high-yield, and high-quality varieties is one of the main keys to further increase production and quality. Before hybridization, we must study the ginseng flowering habits and hybridization techniques in detail in order to work smoothly. For this reason, the author conducted experimental observations in 1960 and 1962. The results are reported below. Materials and Methods This experiment was conducted in Jilin Province, a farmer breed of Da Ma Ya (3 to 5 years old), and in 1960 in the Jilin Province Institute of Special Products (Zuojia District). The number of days required until the beginning of the flowering period, the day and night flowering, the observation of the single inflorescence and single flowering; the same material,
