Embodiment 1

[0023] The method for controlling desert sand includes the following steps: S1. Prepare fertilizer-preserving granules by using a mold. The mold includes a mold body, and a cavity for placing solid fertilizer is arranged inside the mold body, and a core is radially arranged in the cavity. The solid fertilizer is made into a hollow shell by using a mould, through-holes are opened on the shell, and mist-catching cotton is filled in the hollow. The mass ratio range between fog-catching cotton and solid fertilizer is 1:2-18. S2. Place the fertilizer-preserving granules and mix them in the sand. The fertilizer-preserving granules are distributed at different depths in the sand. The volume ratio of the fertilizer-preserving granules and the sand mixed ranges from 1:10 to 50. Water the sand before placing the fertilizer-preserving granules, keep the sand at a depth of 15-25cm moist, and plant seedlings on the sand after placing the fertilizer-preserving granules.

[0024] The temper...

Embodiment 2

[0030] The difference from Embodiment 1 is that the core is made of icicles, and the surface of the core is covered with a waterproof layer. Ice is used to make the core, the ice can be melted into water, and the water can be frozen into ice for reuse. At the same time, the outer surface of the core is covered with a waterproof layer, so as to prevent the solid fertilizer from melting immediately after the icicle melts into water, resulting in the loss of fertilizer particles. Production failed.

Embodiment 3

[0032] The difference from embodiment 2 is that the waterproof layer is fixed radially on the inner wall of the mold cavity, and the two ends of the mold core and the junction of the mold body are provided with plugging heads for opening and closing the mold core. In this way, it is unnecessary to sleeve the waterproof layer on the surface of the icicle every time, and only need to insert the icicle into the cavity between the inner walls of the waterproof layer. At the same time, the plugging head is used to selectively install icicles, and the ice water after the icicles melt is discharged.

Abstract

The invention relates to the technical field of desert control and discloses a method for controlling desert sand. The method for controlling the desert sand comprises the following steps: S1, preparing fertilizer-retaining granules by a mold, preparing a hollow shell from solid fertilizer by the mold, opening a through hole in the shell in a run-through way and filling the hollow position with mist catching cotton; and S2, placing the fertilizer-retaining granules, mixing and stirring the fertilizer-retaining granules into the sand and enabling the fertilizer-retaining granules to be distributed at different depth of the sand. According to the technical scheme and by the method for controlling the desert sand, the problem that plants cannot grow in the existing desert continuously for a long time is solved.

Description

technical field [0001] The invention belongs to the technical field of desert control, in particular to a method for controlling desert sand. Background technique [0002] Deserts mainly refer to barren areas where the ground is completely covered by sand, with very few plants, little rain, and dry air. The causes of deserts mainly include overgrazing, unreasonable felling of trees, etc. Now the global land desertification phenomenon is serious, and the desert area is increasing year by year. Excessive desert area will have a great impact on agriculture, livestock, rivers and infrastructure. For example, the annual increase of the desert area will reduce the agricultural arable area and reduce the national annual grain output; the desert will lead to the degradation of the grassland, which will gradually reduce or even completely lose the dominant grass species suitable for livestock, and the grass will become low and low. Sparse, significantly reduced yields, greatly redu...
