Detailed ways

As shown in Figure 1, a plant protection device for planting on sloping land in arid salinization areas includes a cylinder body 1, both ends of the cylinder body 1 are open, and the bottom of the cylinder body 1 is cut to form a sharp point for easy insertion into the soil Part 101, the side wall of the cylinder body 1 is provided with a number of ventilation holes 2, the tip 101 of the cylinder body 1 is covered with a porous bottom seal 3, the inner and lower layers of the cylinder body 1 are the saline-alkali barrier layer 5 composed of loose materials, and the middle layer is The nutrient layer 6 composed of nutrients and the moisture retaining layer 7 composed of fine sand on the upper layer have a certain gap between the moisture retaining layer 7 and the top of the cylinder 1 , and the gap part forms a water collection area 8 . The top of the cylinder body 1 is cut to form a slope with a certain inclination angle. In this way, when the cylinder body 1 is inserted into the surface of the slope body 9 obliquely, the opening at the top of the cylinder body 1 can be kept horizontal (see Figure 2), so as to facilitate the collection of water. The angle between the top plane of the body 1 and the cross section of the cylinder body 1 is generally controlled at 30-60°. The upper surface of the moisture retaining layer 7 can be flush with the top plane of the cylinder body 1 .

In the utility model, the cylinder body 1 is made of bamboo, its length is 30-50cm, and the inner diameter is 3-15cm; the bottom seal 3 is composed of gauze or barbed wire, and the bottom seal 3 can be bound by ropes or by iron nails 4 Fixed on the bottom of the cylinder 1. The saline-alkali barrier layer 5 is composed of sawdust, stones or a mixture of the two; the nutrients constituting the nutrient layer 6 are nutrient soil, and the components of the nutrient soil can be configured according to different plant species. The height ratio of the saline-alkali barrier layer 5, the nutrient layer 6, the moisture retaining layer 7 and the water catchment area 8 is 1:2-3:0.5-1:0.5-1.
