Industrial production method for potato minituber by using foamed plastic as substrate

Abstract

The invention relates to an industrial production method for a potato minituber by using foamed plastic as a substrate. The foamed plastic substrate comprises nutrient elements needed for the growth of potato. The production method for the potato minituber comprises the following steps: 1) planting a potato test-tube plantlet in the above-mentioned foamed plastic substrate; 2) placing the foamed plastic substrate planted with the potato test-tube plantlet on a culture frame in a greenhouse and carrying out cultivation; 3) controlling temperature and illumination, and carrying out irrigation and fertilization; and 4) carrying out continuous and selectable harvesting so as to obtain the mini-sized potato. The foamed plastic substrate and the industrial production method for the potato minituber provided by the invention realize pure soilless cultivation, have high space utilization rate, are free of the problem of continuous cropping, can realize continuous, planned and selectable harvesting, and are basic foundations of industrial production for the potato minituber.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a factory production method and a foamed plastic substrate of potato microtubers. Background technique [0002] At present, the cultivation of plants has not been able to realize the true soilless cultivation. The following will take potatoes as an example for a specific introduction. [0003] Potatoes have been used as one of the four major staple foods in my country. Increasing production and maintaining variety quality and purity are the goals pursued. [0004] The traditional way of planting is to divide the shoots of potatoes to make seeds. That is to say, the potatoes left over from the previous year are germinated on the hot kang every year, and the buds are cut to make seeds and planted in the field. Because this planting form cannot avoid the degradation of varieties and soil-borne diseases, potato production has been operating at a very low level for...

Problems solved by technology

Although the yield has been increased, as a potato breeding, the above forms still cannot provide true non-toxic purebred potato seeds, at best, they are seeds with a high probability of non-toxic purebred

And the price is high, not suitable for large-scale production and planting
