Micro-potato production method by mist culture method

Abstract

The invention discloses a micro-potato production method by a mist culture method. By the micro-potato production method, micro-potatoes are cultured by the aid of mist spraying technique, the whole culture process is divided into a growth phase, an induction phase and a tuberization phase by combining growth characteristics of micro-tubers, and three different nutrient solutions including growth phase nutrient solution, induction phase nutrient solution and tuberization phase nutrient solution are used, so that better growth of the micro-potatoes is promoted. The micro-potato production method has the advantages that micro-potato growth period is shortened, the tuberization quantity is increased, and single micro-potato weight is increased.

Description

technical field [0001] The invention relates to a plant growth regulator, in particular to a method for producing potato microtubers by aeroponics. Background technique [0002] At present, there are mainly four methods for the production of potato microtubers: one is soil cultivation, where potatoes are directly planted in the soil; the other is soilless substrate cultivation, which combines soilless cultivation with potato bioengineering technology to quickly produce virus-free Microtubers are currently widely used in soilless cultivation methods based on peat, vermiculite, etc.; the third is the test tube method, by changing the formula of the medium, inducing the test tube seedlings to produce many small aerial tubers; the fourth is the aeroponic method, It is to spray the nutrient solution suitable for different periods of development on the rhizosphere of potato plants kept under dark conditions in a timely and appropriate amount, so that the potatoes can get sufficien...

Problems solved by technology

Research shows that soil cultivation is susceptible to infection, and the quality of microtubers produced at the same time is poor, low yield, and long time; soilless substrate cultivation is mainly due to low reproduction coefficient, light weight of a single tuber, and long production time; the test tube method has a long production cycle. There are many limiting factors, which prevent large-scale production, and are only suitable for some special researches; the use of aeroponic cultivation can shorten the production cycle, and at the same time, various physiological indicators and yields of potatoes can be significantly increased

[0003] Trace elements play a vital role in the growth of potato minitubers and the formation of tubers. At the same time, the requirements of nutrient elements in different growth stages of potato minitubers are also different. At present, there are few research reports on these two aspects, and many have been published. The formulations of the seed mist spray liquid nutrient solution are similar, most of them are based on MS nutrient solution, the biggest difference is the ratio of N, P, K in the nutrient solution and the nutritional form of nitrogen
