Method for raising seedlings of carex brunneopilosa seeds

Abstract

The invention relates to a method for raising seedlings of carex brunneopilosa seeds. On the basis of an existing rapid germination method, a greenhouse container cultivation method is adopted, the carex brunneopilosa seeds with dormancy broken are subjected to rooting powder soaking treatment with the specific concentration of 10-30mg. Kg<-1> and the specific time of (6-18h), a specific seedlingraising substrate is used, the specific sowing depth of (0.5-1.0cm) is set, the seeds can rapidly emerge and are uniform, the seedling rate of nursery stocks is high, the nursery stocks grow robustly,the seedling raising period and the transplanting rejuvenation period can be effectively shortened, the transplanting survival rate is increased, and the technical problems that in ecological restoration of high-cold degraded grasslands, the carex brunneopilosa seeds are difficult to raise seedlings and slow in growth, and the method is not beneficial for being widely applied and popularized to ecological restoration of the degraded grasslands are solved.

Description

technical field

[0001] The invention relates to the technical field of seedling raising, in particular to a method for seedling raising of Carex brown scales. Background technique

[0002] Gansu Yellow River Shouqu (Maqu) National Nature Reserve is located in the east of the Qinghai-Tibet Plateau, the roof of the world known as the "third pole of the earth", in Maqu County, Gannan Tibetan Autonomous Prefecture, Gansu Province. It is the best-preserved Qinghai-Tibet Plateau wetland area in the world. The largest and most representative alpine swamp wetland, its unique geographical environment plays an irreplaceable role in maintaining water resources and ecological security in the Yellow River Basin. However, in the past 60 years, under the frequent interference and destruction of natural and human factors, coupled with historical diversions of the Yellow River, incisions, and groundwater level declines, the ecology of the small area of ​​Maqu alpine grassland has shown a ser...
