Safe overwintering technique of tree plant in high-cold area

Abstract

The invention discloses a safe overwintering technology for tea plants in severe cold regions. A layer of plastic film small shed is covered on the tea plants covered inside a plastic greenhouse in winter, films are removed for the plastic greenhouse in spring and the irrigation is carried at proper time, therefore, the technical problem of planting the tea plants in the severe cold regions is solved. The plastic greenhouse utilizes a column-less steel frame, the span of the greenhouse is 8 m, and the height of the greenhouse is 2.4 m; the greenhouse film adopts a polyethylene anti-drop film with the thickness of 0.08 to 0.12 mm, a polyethylene anti-aging film, and the like; and the lowest temperature in the greenhouse can be increased by 3 to 9 DEG C, and the relative humidity can be improved by 8 to 12 percent. The plastic small shed is built on the surface of a tea plant by using bamboo strips and plastic films, the height of the plastic small shed is 1 to 1.6 m, and the span of the plastic small shed is 0.6 to 1.2 m. The plastic small shed is dissembled in February, and the films of the plastic greenhouse are removed in middle April. The invention solves the problem that the tea plant cultivating area is available within the latitude of 36 degrees north, can prevent the harm from the cold spell and the late spring coldness, reduces the overwintering hibernation time of the teat plants as possible and promotes tea shoots to sprout in advance.

Description

technical field [0001] The invention relates to tea tree planting technology, in particular to a technology for safe overwintering of tea trees in alpine regions. Background technique [0002] China is the earliest country in the world to cultivate tea trees, with a history of 4,000 years. In the 8th century AD, Lu Yu of the Tang Dynasty pointed out in his "Tea Classics" that "the tea maker is also the Jiamu in the south", indicating that tea trees were produced in southern China; in 50 BC It has been introduced to the Sichuan area. In the 5th century AD, tea trees had been widely extended to the north and south of the Yangtze River. According to records in the Tang Dynasty, the tea trees were distributed in the south of Zhongnan Mountain in Qinling Mountains, south of Henan, east of Jiange, all over the banks of the Yangtze River, Jiangsu, Anhui, Huaihe River, etc. It was introduced to Japan at the end of the 7th century and the beginning of the 8th century. After the 17th ...
