A kind of production method of potato miniature tuber that germinates without dormancy

Abstract

The invention discloses a method for producing potato miniature tubers that germinate without dormancy, which comprises the steps of cultivating miniature tubers, aerosol planting of double-leaf node stem segments, nutrient solution supply, aerosol culture management, and axillary bud potato planting steps. Greenhouses use conventional methods to plant miniature tubers to plants with 8-10 leaves; only 2-4 leaves in the lower part of the plant are kept, and the cut middle and upper leaves are planted in aeroponics facilities in the form of double-leaf nodes to prepare for nutrient solution supply, aeration Aeroponic management. Its beneficial effect is to directly obtain potato miniature tubers that germinate without dormancy. This method can obtain miniature tubers with a bud length of 1∼3 cm in 10∼14 days, shorten the planting cycle of miniature tubers, reduce the number of seedlings or miniature tubers, and ensure Germination rate, increase the reproduction coefficient of miniature tubers. Simultaneously, the problem of germination rate reduction caused by the occurrence of diseases and insect pests and water loss during storage and germination is avoided. In addition, the remaining 2∼4 leaves in the lower part can continue to provide sufficient nutrients for the formed microtubers.

Description

technical field [0001] The invention belongs to the rapid propagation technology of potato microtubers in the field of agricultural technology, and specifically refers to a production method of potato microtubers that germinate without dormancy. Background technique [0002] Potato is one of the four major food crops next to wheat, rice, and corn. It is also a high-efficiency economic crop that is used as grain, vegetable, feed, and industrial raw materials. It mainly uses tubers for vegetative propagation. Once seed potatoes are infected with diseases such as viruses, fungi, and bacteria, it is easy to cause variety degradation and a decline in quality and yield, which will severely impact the development of the potato processing industry. The most effective way to solve the problem is to mass-produce virus-free seed potatoes. In the production process of virus-free seed potatoes, the rapid propagation speed of virus-free test tube seedlings and the number of miniature tub...
