Problems solved by technology

[0003] At present, when sugarcane wild species resources are collected in the wild, due to the large number of materials to be collected and the inconvenience of carrying and transportation, less materials are collected in the wild for each material, and there are differences in climate and environmental conditions between the material collection area and the conservation area , the germination and growth of wild sugarcane resource materials are relatively slow when they are directly stored in the resource nursery after collection, and some materials gradually die due to poor growth during the conservation process, which limits the in-depth research and utilization of wild sugarcane resources, thus restricting sugarcane. Germplasm innovation, variety improvement and the development of sugarcane planting production industry; in the prior art, there is no relevant research to solve this problem

Embodiment 1

[0028] Such as figure 1 shown

[0029] A method for improving the survival rate of sugarcane wild species resource conservation, comprising the following steps:

[0030] 1) Choose a medium or large flower pot with good drainage and ventilation, and pre-fill the pot with impurity-free soil to 1 / 2 of the total volume;

[0031] 2) Number the sugarcane wild resource materials collected in the field, plant them in flower pots after numbering, and further cover with soil to 3 / 4 of the total volume of the flower pots, water them thoroughly and cover them with transparent plastic films, and then place them in a greenhouse at about 30°C for cultivation Let the seedlings germinate, and when the seedlings grow to 14-16cm, remove the plastic film and continue to cultivate;

[0032] 3) When the tallest stem of the seedling material grows to 1.4-1.6 meters, cut off the main stem and most of the well-developed tiller stems from about 10cm away from the soil surface in the pot, and continue...

Embodiment 2

[0045] In September-October 2016, a total of 7 hand-cut secret resource materials were collected around Kunming, numbered 2016-1, 2016-2, 2016-3, 2016-4, 2016-5, 2016-6 and 2016-7, After collection, it was treated with the method of the present invention and was preserved in the sugarcane wild germplasm resource nursery of the Houshan Sugarcane Research Institute of Yunnan Agricultural University located in Heilongtan before the arrival of the rainy season in Kunming in May 2017. By November 2017, 7 materials All have survived and each material has more than 50 tiller stems ( figure 2 ), the growth is vigorous, and the conservation survival rate reaches 100%; and the same material that is directly planted in the resource garden after collection still has only 10 or less short tiller stems even in September 2018, and the growth is poor ( image 3 ), one of the materials is dead, and the other 2 materials also show signs of death.

Abstract

The invention discloses a method for improving a survival rate of sugarcane wild species conservation. The method relates to the technical field of sugarcane wild species conservation. The method forimproving the survival rate of sugarcane wild species conservation is characterized in that acquired sugarcane wild resource materials are planted in a potting manner before being planted in a resource garden, the tillering capability of the sugarcane wild resource materials is effectively improved, new roots developed from tillering stems form a strong root system, the sugarcane wild resource materials reach a survival rate of 100% after being transplanted into the resource garden, and the survival rate of sugarcane wild species conservation is improved. The method facilitates the intensive study and utilization of the sugarcane wild species resources, thereby promoting sugarcane germplasm innovation, variety improvement and development of the sugarcane planting and production industry.

Description

technical field [0001] The invention relates to the technical field of sugarcane wild species conservation, in particular to a method for improving the survival rate of sugarcane wild species resource conservation. Background technique [0002] Sugarcane (Saccharum spp.) is a tall plant of the genus Saccharum in the Gramineae subfamily Saccharastrae. In the sugarcane subfamily, there are also some genera that are closely related to sugarcane and have important utilization value for sugarcane breeding, such as Erianthus, Miscanthus, Sclerostachya, Narenga And Imperata (Imperata) and so on. The plants of these genera together with Saccharum are collectively referred to as "Saccharum complex". Because these plants have many excellent traits such as strong tillering, strong stress resistance, and barrenness tolerance, they have potential use value for the cultivation of new sugarcane varieties or the improvement of original varieties, and they are constantly being studied and ...
