The cassava is planted by taking seed stems as seeds and cutting the stems for cultivation. The seeds are generally planted in the next year after the winter by cutting, harvesting and storing the seed stems in the current year. The overwintering storage of the seed stems is poor, the germination rate of the seed stems is low, the seedling shortage of the cassava is serious, the yield of the cassava is directly reduced, the plant growth, the root tuber differentiation and the like are also influenced, and the yield and the quality of the cassava are further influenced.
North latitude 23.8 。 The heavy frost region and low temperature region in north, including Guangxi, guangdong, north Yunnan and Hunan, jiangxi and Zhejiang provinces, are all of ChinaAn edge area of cassava planting. The area is an unsafe area for overwintering storage of the cassava seed stems, frost and low temperature occur each year because of relatively low temperature in winter, the overwintering storage difficulty of the cassava seed stems is high, and the whole seed stems can be necrotized if the cassava seed stems are improperly protected.
At present, the overwintering storage of the cassava seed stems in the heavy frost area and the low temperature area generally adopts a winter protection karst cave or cellar storage method or a vertical stacking method of a plastic greenhouse and a small arch shed to store the cut seed stems, and also has the functions of cutting the seed stems and sealing wax for storage. However, the methods require strict storage conditions and management measures, the storage effect is not ideal, the survival rate of the cassava seed stems is low, and the survival rate of the cassava seed stems is less than 70%. If the cassava is in contact with the severe frost, rain and snow, a large number of seed stems freeze up, rot or dry up, and the gap of improved seeds is very large, so that the healthy development of the cassava industry is restricted to a great extent.
How to overcome the defects in the prior art, a feasible overwintering storage method for the cassava seed stems in a heavy frost area and a low-temperature area is found, and the survival rate of the cassava seed stems is improved, so that the technical problem which is urgently solved by the person skilled in the art is solved.
