随着农业种植结构调整,马铃薯生产成为山区农民增收的主要途径之一。从1998年我县建立万亩马铃薯秋繁基地以来,所生产的脱毒种薯,在次年的大田春种中长势良好,比本地种产量翻一番,取得了良好的经济效益。现将脱毒马铃薯秋繁技术介绍如下: 一、选择繁育田,选用良种 为了确保脱毒种薯在繁育过程中不再受病毒侵染,保证种薯的质量,选择繁育田的条件为:1.无传播性病毒和细菌性病害的,前作以水稻田为佳,不能是种马铃薯、茄科作物或十字花科的地块。2.选用隔离条件相对较好的地块,如无水源、风源传染等,四周200米内不能种有马铃薯、茄科蔬菜、油菜等作物。
With the adjustment of agricultural planting structure, potato production has become one of the main ways for mountain farmers to increase their incomes. Since the establishment of 10,000 mu potato autumn base in our county in 1998, the virus-free seed potato produced has enjoyed good growth in the next spring field and has doubled the local production and achieved good economic benefits. Now autumn virus-free potato technology is as follows: First, select the breeding fields, the selection of elite To ensure that virus-free seed in the breeding process is no longer infected with the virus to ensure the quality of seed potatoes, the choice of breeding conditions: 1 Non - transmissible viruses and bacterial diseases, preferably rice fields, can not be potatoes, solanaceous crops or cruciferous plots. 2. Use relatively good isolation conditions of the land, such as non-water sources, sources of infection, not to be planted within 200 meters of potatoes, solanaceous vegetables, rape and other crops.
