Embodiment 1

[0019] Embodiment 1 adopts the following steps to realize the anti-frost of macadamia saplings in the high-altitude mountainous area of ​​Xingyi City, Guizhou Province:

[0020] (1) Fertilize and water at the right time to cultivate strong autumn shoots: apply 1 shoot-promoting fertilizer and strong shoot fertilizer before the autumn shoots sprout and during the leaf turning period, apply 80g of high-nitrogen, low-phosphorus, medium-potassium compound fertilizer to a single plant, and apply 80g of high-nitrogen, low-phosphorus, medium-potassium compound fertilizer before the leaves turn. Spray 0.4wt.% potassium sulfate and 90mg / L prohexadione calcium on the foliage during the coloring period to promote the robustness and maturity of autumn shoots; after the autumn shoots are mature, apply 8kg of decomposed pig manure, 0.8kg of cake fertilizer and quicklime to each plant 0.1kg, and control nitrogen and water to suppress winter shoots;

[0021] (2) Fertilize outside the roots to...

Embodiment 2

[0024] Embodiment 2 adopts the following steps to realize the anti-frost of macadamia saplings in the high-altitude mountainous area of ​​Zhenkang County, Yunnan Province:

[0025] (1) Fertilize and water at the right time to cultivate strong autumn shoots: apply 1 shoot-promoting fertilizer and strong shoot fertilizer before the germination of autumn shoots and during the leaf turning period, apply 60g of high-nitrogen, low-phosphorus, and medium-potassium compound fertilizer to a single plant, and apply 60g of high-nitrogen, low-phosphorus, medium-potassium compound fertilizer before the leaves turn. Spray 0.3wt.% potassium sulfate and 105mg / L prohexadione calcium on the leaves during the coloring period to promote the robustness and maturity of autumn shoots; after the autumn shoots are mature, apply 6kg of decomposed pig manure, 0.6kg of cake fertilizer and quicklime to each plant 0.15kg, and control nitrogen and water to suppress winter shoots;

[0026] (2) Fertilize outs...

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...
