Description

technical field [0001] The invention relates to various nutrient supply technologies in plant soilless cultivation, and at the same time takes into account disease prevention and control technologies, in particular to a potato spray cultivation nutrient solution for potato spray cultivation to produce miniature potatoes and a preparation method thereof. Background technique [0002] Potato is the fifth largest crop in the world, and my country is the largest potato growing country. Since potatoes are asexually propagated crops, viruses will accumulate in perennial planting, which will cause serious degradation of potato seed tubers. Therefore, virus-free seed potato breeding based on shoot tip tissue culture virus-free technology and soilless culture virus-free mini-tuber breeding technology Technology plays a very important role in the potato industry. Potato substrate-free spray cultivation is a new type of micro-tuber production technology developed in recent years. It u...
