Method for preventing macadimia nut saplings from frosting in mountainous area at high altitude

Abstract

The invention discloses a method for preventing macadimia nut saplings from frosting in a mountainous area at a high altitude and belongs to the technical field of fruit tree frosting prevention. Themethod disclosed by the invention comprises the following steps: (1) supplying fertilizers and water at appropriate time, and culturing and strengthening autumn growth; (2) applying fertilizers outside roots, and culturing and strengthening tree vigor; and (3) earthing collars, and bagging whole plants. The method disclosed by the invention is capable of preventing the macadimia nut saplings planted in the mountainous area at the high altitude from frosting to the maximum extent and increasing the survival rate of the saplings, is convenient to operate and easy to popularize and plays an active instruction role in preventing the macadimia nut saplings planted in the mountainous area at the high altitude from frosting.

Description

technical field

[0001] The invention relates to the technical field of anti-frost technology for fruit trees, in particular to a method for anti-frost of young macadamia nut trees in high-altitude mountainous areas. Background technique

[0002] Macadamia spp., also known as macadamia nut, is native to Australia and belongs to the evergreen tree fruit tree of the genus Macadamia F.Mull in the family Proteaceae. Macadamia kernels are rich in nutrition. The market demand is about 400,000 tons, but the current output is only 220,000 tons, which is far from meeting the market demand. Therefore, various planting areas are actively introducing or expanding the planting area. In recent years, my country's Yunnan, Guangxi, Guangdong, Guizhou and other places have set off a planting boom, and the Linzhi area of ​​​​Tibet is also actively introducing and testing varieties. According to statistics, at the end of 2018, the planting area of ​​macadamia nuts in my country was about 4.5 m...
