Germination accelerating method capable of increasing sprouting rate of saccharum officinarum seeds and application of germination accelerating method

Abstract

The invention belongs to the technical field of crop cultivation, and particularly relates to a germination accelerating method capable of increasing the sprouting rate of saccharum officinarum seedsand an application of the germination accelerating method. In order to provide a germination accelerating or seedling raising method capable of increasing the sprouting rate of saccharum officinarum seeds, the invention provides the germination accelerating method capable of increasing sprouting rate of saccharum officinarum seeds. The germination accelerating method capable of increasing sprouting rate of saccharum officinarum seeds comprises the steps of building a film arched shed on seedling raising substrates on which saccharum officinarum seeds are sown, then performing transferring intoa culture green house, and performing germination accelerating and germinating culture under certain condition for 3-5 days. When the saccharum officinarum seeds are subjected to germination acceleration by the method, germination of saccharum officinarum hybrid seeds can be promoted, the sprouting rate is high, and seedling emergence is quick and tidy; when the method is applied to cultivation of saccharum officinarum seedlings, the quantity and the quality of saccharum officinarum seedling groups in each hybrid combination can be guaranteed; and besides, when the germination accelerating method provided by the invention is used, sowing time is not influenced by external environment.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a germination accelerating method for increasing the germination rate of sugarcane seeds and an application thereof. Background technique [0002] Sugarcane (Saccharum officinarum L.) is the most important sugar crop in my country, mainly distributed in southern regions such as Guangxi, Yunnan, Guangdong, and Hainan. At present, the process of breeding new sugarcane varieties is mainly to obtain hybrid seeds through conventional cross-pollination methods, grow the obtained hybrid seeds to obtain seedlings, then transplant the cultivated seedlings to the field, and finally pass the pedigree selection method or family selection method. Perform system screening. Since sugarcane is an allopolyploid plant with a very complicated genetic background, breeders need to sow tens of thousands to hundreds of thousands of seedlings every year for selection. Therefore, t...

Problems solved by technology

However, if the environmental temperature and humidity are not controlled correctly, such as rainy weather after sowing, insufficient light, and low temperature for too long, etc., it is easy to cause mildew and no germination or low germination rate of hybrid seeds; In continuous high temperature weather, it is necessary to use spraying and watering in time to cool down and increase humidity based on experience, but it is easy to water not in time or excessive or uneven watering, which may easily cause hybrid seeds to not sprout or rot.
