Problems solved by technology

The degree of dormancy of seed potatoes affects the morning and evening of field emergence, uniformity and yield, especially prolonging the germination and growth of tubers, and ultimately affecting the increase in yield. If the potatoes are not stored properly, the potatoes will germinate early, which will cause the loss of nutrients and Dehydration and wilting will affect the emergence rate, plant growth and yield. Some varieties have a long dormancy period or slow germination. When production needs, the seed potatoes will be accelerated to break dormancy and sow in time

Abstract

The invention provides a storage method for increasing the germination rate of seed potatoes, and belongs to the technical field of crop seed storage. The method comprises the following steps that S1, freshly harvested seed potatoes are subjected to callus treatment for 5-8 days; S2, the seed potatoes in S1 are soaked for 5-20 minutes with a pretreatment agent containing an erycibe roxb plant extract, and is dried in a dark place; S3, the seed potatoes in S2 are placed in a mesh bag or a packaging box, and stacked in a refrigeration house for storage. The storage method for increasing the germination rate of the seed potatoes has the advantages that the content of isochlorogenic acid in the erycibe roxb plant extract is high, and the yield of prepared N-cocoyl complex amino acid is high; the method can reduce the activity of soluble starch synthase, polyphenol oxidase and peroxidase, inhibit the growth and reproduction of microorganisms in the seed potatoes, and prolong the dormancy period of tubers, while in the dormancy breaking process of the seed potatoes, the activity of the soluble starch synthase, polyphenol oxidase and peroxidase is improved, and the germination rate is increased.

Description

technical field [0001] The invention belongs to the technical field of crop seed storage, and in particular relates to a storage method for improving the germination rate of seed potatoes. Background technique [0002] As a major crop with wide adaptability, strong stress resistance and high unit yield, potato is widely cultivated in various parts of my country. The annual cultivated area in the country has been stable at about 5 million hectares for many years, and the annual demand for seed potatoes is 10 million tons. More than 1 million tons of seed potatoes are lost during storage every year. Good storage facilities and storage techniques are the key to reducing storage losses. The degree of dormancy of seed potatoes affects the morning and evening of field emergence, uniformity and yield, especially prolonging the germination and growth of tubers, and ultimately affecting the increase in yield. If the potatoes are not stored properly, the potatoes will germinate early,...
