马铃薯脱毒原种就是将脱毒苗生产的微型种薯(即原原种)在大田土壤中种植、收获的农业栽培技术的实施过程。马铃薯种薯生产,除满足一般的栽培技术外,尚有以下特殊的要求。1.原种生产中的特殊技术要点原种生产要求种植在肥水条件较好的地块;在病毒病害多发区采用网室种植;在病害少的地区如无马铃薯等同病源作物的地方采用自然隔离种植。此外,马铃薯是忌氯作物,不能施含氯的肥料;微型薯的休眠期较长,切忌种植未通过休眠期的原原种。产量指标及构成因素
The original virus-free potato seed is the implementation of the agricultural cultivation technique of planting and harvesting miniature seed tubers (that is, the original seedlings) of the virus-free seedlings in the field soil. Potato seed production, in addition to meet the general cultivation techniques, there are the following special requirements. 1. Special technical points in the production of original seeds The production requirements for original seeds are planted in plots with good fertilizer and water conditions; planted in cymbals in virus-prone areas; natural isolation in areas where there is less disease, such as potato-free crops Planting. In addition, the potato is to avoid chlorine crops, can not be applied chlorine fertilizer; microtubes dormancy longer, should not be planted without the dormant period of the original species.
