Embodiment Construction

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] Yingkou area is located in the central city of Liaodong Bay, with a latitude of 40.65°N. The historical minimum temperature in winter is minus 33°C. The average minimum temperature in the past eleven years is around -21°C, of ​​which there are 5 years from -21°C to -26°C. It belongs to the northern temperate zone. climate. In 2005, mother plants of bamboos were introduced from Jiangsu and other places, including Polygonatum inlaid with Polygonatum, Bamboo, and Emerald Bamboo, and were domesticated in 3 locations through the c...

Abstract

The invention relates to the field of bamboo seed cultivation, in particular to a method for cultivating and acclimating cold-resistant bamboo species in the high-latitude Liaodong Bay region, which adopts comprehensive cold-resistance methods such as climate acclimation method, and includes the following aspects: (1) cold-acclimated basic materials and habitats (2) Daily monitoring and management of domestication; (3) Overwintering management. The cultivation and acclimation method of the present invention neither adopts greenhouse coverage nor utilizes geothermal pipelines, but adopts pure open air for cultivating and domesticating, and the bamboo species domesticated by the method of the present invention are fully adapted to the local climate and soil, and can grow like southern bamboos. Bamboo shoots grow with luxuriant branches and leaves, and the mother plant is transplanted from the domesticated provenance, and cultivated in other places in the local area. It is not covered in winter and grows well, which shows that the bamboo species in the provenance already have cold resistance genes, which can Multiply.

Description

technical field [0001] The invention relates to the technical field of bamboo seed cultivation, in particular to a method for cultivating and domesticating cold-resistant bamboo seeds. Background technique [0002] In recent years, all over the country have carried out large-scale cultivation experiments of artificial introduction of bamboo from south to north, and achieved great success. When the climatic conditions are such that the annual average temperature is within 11°C, the average temperature in January is minus 5.2°C to 2.2°C, the extreme minimum is around minus 20°C, and the annual precipitation exceeds 500mm, bamboo can also grow, making some more resistant ones Scattered bamboo and mixed bamboo were introduced to the north of the Yellow River. In terms of regional distribution, it has expanded from the southern tropics and subtropics to the northern warm temperate zone, and from the overall distribution to within 40° north latitude. But the cold temperate zone ...
