1.通过試驗証明生育期长短不同的馬鈴薯在同时收获的条件下,生育期短,块茎未充分成熟的处理,并未減輕退化程度;在芽眼尚不可能萌动的結薯初期,馬鈴薯植株如处于高温条件下也可能加重退化,从而说明馬鈴薯的退化并非由于过度成熟产生自然衰老,亦非因为高温影响了萌动的芽眼,使其衰老所致。 2.早收及夏播的馬鈴薯,除去可能因为低温有利于馬鈴薯抗病力的增強外,更主要的是由于低温条件不利于花叶型病毒的增殖和运轉,降低了新生块茎內病毒浓度的結果。 3.为了从根本上解决馬鈴薯退化問題,应采取以隔离病源,严格汰除病株病薯,防治媒介昆虫,控制传播等措施为中心,生产无毒种薯,并結合选用耐病品种和二季栽培的留种技术,进行综合防治。 4.在推行二季栽培留种技术时,应适当推迟夏播播期,夏播所用种薯必須春季提早收获,并結合选株、选薯等措施。
1. Through experiments to prove that the different growth stages of potatoes at the same time harvest conditions, short growth period, tubers did not fully mature treatment, did not reduce the degree of degradation; bud eye is not likely to germinate in the early potato, potato plants such as in Degradation may also be aggravated under high temperature conditions, indicating that potato degradation is not caused by natural aging due to over-maturation, nor is aging due to high temperature affecting budding eyes. Early harvesting and summer sowing of potatoes, removal may be due to low temperature conducive to enhancing the resistance of potato, the more important is due to low temperature conditions is not conducive to the proliferation and operation of mosaic virus, reducing the virus concentration in the nascent tuber the result of. 3. In order to fundamentally solve the problem of potato degeneration, we should take measures to isolate the source of the disease, strictly eliminate the diseased plants, prevent and control vector insects, control the spread and other measures as the center to produce non-toxic seed potatoes, and select the resistant varieties and the second season cultivation The remaining technology, for comprehensive prevention and treatment. 4. In the implementation of planting techniques for planting in the second quarter, the summer sowing date should be appropriately postponed. The seed sowing for summer sowing must be harvested early in spring and combined with the selection of strains and selection of potatoes.
