Saline-alkali soil tree protecting device

Abstract

The invention relates to the technical field of saline-alkali soil nursery stock protection, and provides a saline-alkali soil tree protecting device which comprises a supporting frame and a mulching film. The supporting frame comprises at least three clamp hoops, a clamp hoop ribbon which is adjusted and fixed through a ribbon locking device is connected between every two adjacent clamp hoops, and a supporting rod is hinged to a hinging part of a clamp hoop hinging lifting lug on each clamp hoop. Each supporting rod comprises an inner supporting rod body and an outer supporting rod body connected with the inner supporting rod body in a sleeving mode, wherein a directional locking device is arranged at the upper end of the outer supporting rod body, a supporting rod base is hinged to the lower end of the outer supporting rod body, a water injecting pipe penetrates through the supporting rod base, and the output end of the water injecting pipe communicates with a water seepage and ventilation pipe network. Each base table is sleeved with a mulching film tightening clamp hoop, and a tree base is sleeved with a mulching film binding band. The supporting height and surrounding diameter of the saline-alkali soil tree protecting device can be automatically adjusted along with growth of a tree, the tree is effectively supported and protected, the breathing requirement of the root is met, watering and fertilizer and pesticide applying can be conveniently conducted on the tree, and the mulching film can be effectively protected.

Description

technical field [0001] The invention belongs to the technical field of nursery stock protection in saline-alkali land, and in particular relates to a device for protecting trees in saline-alkali land. Background technique [0002] The greening project is the main part of the garden project. It has the function of constructing a good ecological environment and regulating human life. With the gradual expansion of the urban framework in various parts of the country in recent years, and the active development of activities such as the establishment of "national garden cities", "forest cities" and "ecological cities", the cause of landscaping has also been greatly developed. [0003] The coastal area is known as the "Golden Coast" due to its unique geographical location and resource advantages. However, due to the restriction of saline-alkali land, the vegetation ecosystem in coastal areas is extremely fragile and the ecological environment is poor, which greatly affects its dev...
