近年来,番茄栽培面积不断扩大,生产上对产量、品质等各经济性状的要求也越来越高。但番茄病害也日趋严重,不少地区不但夏番茄难种成,春番茄单产也大幅度降低。例如,北京市面积扩大近一倍而总产反而减少,致使北京市从五十至六十年代番茄供应充裕变成近年旺季不旺、淡季少见的严重局面,群众意见很大。全国不少地区也有类似情况。造成减产的直接原因是病毒病等的危害。所以对番茄品种的抗病性要求变得重要起来。现在,一个番茄品种如不能经受当地主要病害的考验就难以推广。但任何抗病品种的抗性都是相对的,运用不当就易失败。现就目前我国番茄抗病品种利用的几个问题谈几点看法。
In recent years, the growing area of tomato cultivation, production, production, quality and other economic traits requirements are getting higher and higher. However, tomato diseases are also becoming more serious. In many areas, not only is it difficult for summer tomatoes to grow into varieties, but spring tomato yields have also been significantly reduced. For example, the area in Beijing nearly doubled while the total output decreased. As a result, Beijing’s supply of tomatoes from the 1950s to the 1960s turned into a serious situation with no peak season in recent years and a rare season in low season. The opinions of the masses are very high. In many parts of the country, there are similar situations. The direct cause of the cut is the harm of viruses and the like. Therefore, the resistance to tomato varieties become more important. Now, a tomato variety can not be promoted if it can not withstand the test of the major diseases in the area. However, the resistance of any resistant variety is relative, and it is easy to fail if not used properly. Now on the use of several varieties of resistant varieties of tomato in our country to talk about several points.
