Description
Technical Field
The invention belongs to the technical field of fruit tree cultivation, and particularly relates to a fruit tree cultivation pit and a cultivation method thereof in arid and cold regions.
Background
The average temperature of the coldest month in the arid and cold regions is about minus 10 ℃, the lowest temperature reaches minus 30 ℃, the thickness of a frozen soil layer is 0.8 to 1 meter, the growth and population distribution of fruit trees are seriously influenced in cold weather, the open cultivation can cause the twigs of the fruit trees to be slightly drawn, the yield and the quality are seriously influenced, and a plurality of fruit trees can not safely overwinter in the region. In the area, a protective land (greenhouse) is adopted for planting, and a cover (straw mat) is a common technical measure for fruit trees to live through the winter so as to protect the fruit trees from being frozen; the construction and maintenance costs of the protected area (greenhouse) are too high, and fruit growers generally do not want to adopt the protected area. The operation mode of the comforter (straw mat) is more willing to be adopted to protect the fruit trees from wintering, but the operation process is complex and seriously influences the tree shape, and in order to meet the cultivation requirement in the production, the fruit trees are trimmed into a fan shape or a creeping shape so as to reduce the workload of the comforter (straw mat); and the branches are easy to be folded due to excessive snow accumulation in winter. So far, the height of fruit trees such as peach trees, figs, pomegranate and the like cultivated in drought and cold regions is not more than 1.5 meters, most of the fruit trees are planted in a creeping manner, the tree shape is abnormal, and the yield and the quality of the fruits are seriously influenced. Therefore, a cultivation method with low cost and safe overwintering is urgently needed for fruit trees in arid and cold areas.
