脱毒马铃薯芽栽,即将原原种大中型薯块在酿热阳畦内催芽,再将长至一定规格的薯芽定植于大田。该方法能节约种薯(大田常规播种亩需块茎100公斤,而芽栽每亩仅用20公斤左右),加快脱毒薯繁殖速度。具体方法如下:1.建床与催芽根据种子多少确定阳畦大小,深度83厘米,垫热马粪33厘米,踩实后填肥沃沙壤土26厘米,浇足底水,上覆塑料薄膜。在4月底5月初,将选择好的脱毒薯原原种平放于阳畦,覆土6厘米,盖好薄膜。一般出苗前不浇水。待
Virus-free potato bud planter, about the original large and medium-sized potato tuber germination in the heat Yang Yang, and then grow to a certain size of potato buds planted in the field. This method can save the seed potato (field conventional seeding acres of tubers need to be 100 kg, while the bud planted only 20 kg per mu) to speed up the virus-free potato breeding speed. The specific methods are as follows: 1. Build beds and sprouting According to the number of seeds to determine the size of the sunburns, the depth of 83 cm, pad hot horse manure 33 cm, step on the real fertile sandy loam 26 cm, pour foot of water, overlying plastic film. At the end of April and early May, will choose a good virus-free potato raw plains lay flat Yang, Tu 6 cm, covered with film. Generally not before emergence of watering. Wait
