Water-supplementing fertilizing device for sandy land

Abstract

The invention discloses a water-supplementing fertilizing device for sandy land. The water-supplementing fertilizing device comprises an accommodating box embedded in sandy soil. An accommodating cavity is arranged in the accommodating box, a water bag is installed in the accommodating cavity, more than one water outlet port is arranged on the two sides of the water bag, each water outlet port penetrates water outlet holes in the side wall of the accommodating box to the end face of the outer side of the accommodating box, the upper end face of the water bag is protruded out of the upper end face of the accommodating box, a cover plate is installed on one side of the accommodating box through a hinge, the lower end face of the cover plate is provided with a protruded plate opposite to the accommodating cavity, the protruded plate is opposite to the water bag, one end of the water bag is provided with a water inlet connector, and the water inlet connector is connected through a water inlet hose. The water-supplementing fertilizing device is mainly used for soil water supplementing of a sand area, clear water with a fertilizer can be injected into the water bag, uniform and slow water supply is achieved through the water outlet ports on the two sides of the water bag, a large fertilizing pouring device does not need to be used, the cost is reduced, and the operation is also more convenient.

Description

technical field [0001] The invention relates to an irrigation and fertilization device, in particular to a water replenishment and fertilization device for desertified land. Background technique [0002] In recent years, desertification is rapidly eroding a large area of ​​land resources. Whether in agricultural or pastoral areas, desertification has brought serious harm to the local economy, ecology and society. With the intensification of desertification, large tracts of farmland have been desertified, crop yields have been reduced, and even reached failure. At the same time, in pastoral areas, large tracts of fine grassland resources have been swallowed up, causing greater pressure on grassland resources that originally carried too much livestock. Whether it is farmland or grassland desertification, it has brought serious social problems. Hunger and poverty have always plagued local farmers and herdsmen. Therefore, avoiding and delaying the desertification of land resour...

Problems solved by technology

[0003] The sandy land itself has low nutrient content and poor water retention capacity. Therefore, improving the soil composition of the sandy land is the key to sand control. At present, the improvement of the composition of the sandy land is mostly through artificial fertilization, and the fertilizer is directly sprinkled on the surface of the sandy land by hand. Moreover, desertification The land is short of water, and most of the water is replenished by natural precipitation. However, due to the strong wind and sand in the sandy land, it is easy to blow away the fertilizer sprinkled on the surface of the sandy land. At the same time, the water on the surface of the sandy land is also easily blown dry, resulting in the improvement effect not ideal
