Water and fertilizer integrated drip irrigation method suitable for mountain orchards

Abstract

The invention discloses a water and fertilizer integrated drip irrigation method suitable for mountain orchards. Based on a movable head part, a drip irrigation pipe network is arranged in a mountainorchard, during different growth periods, a certain fertilization formula is used, and the drip irrigation pipe network is used to carry out water and fertilizer integrated drip irrigation on the orchard to supplement water and nutrients. The water and fertilizer integrated drip irrigation method is suitable for the mountain orchards in arid and semi-arid areas, the facility cost of a drip irrigation system in the mountain orchards can be reduced, and the water and fertilizer utilization efficiency are improved, so that the yield, fruit quality and economic benefits of the orchards are improved.

Description

technical field [0001] The invention belongs to the fields of farmland water conservancy and water-saving irrigation, and relates to the arrangement of drip irrigation pipe networks in mountainous orchards in arid and semi-arid regions, and the drip irrigation and fertilization formula and mode of integrated water and fertilizer. Background technique [0002] The shortage of resources, environmental safety and other issues force the use of agricultural water and chemical fertilizers to develop in the direction of efficient agricultural production technologies such as integrated water and fertilizer drip irrigation. Existing drip irrigation system is made up of parts such as water source, head, trunk pipe, branch pipe and capillary pipe. The first part includes filtering and fertilizing devices, as well as monitoring equipment such as intake and exhaust valves, pressure gauges, flow meters and valves. Among them, the filtering and fertilizing devices are the key equipment of ...

For example, the Chinese patent CN202663896U proposes a mobile drip irrigation machine, which includes a water storage device, a mobile head and a drip irrigation main body. Although it can be used in turn in a mobile manner, the irrigation area is limited and it is not suitable for moving between different plots in the mountains.

Chinese patent CN201069940 proposes a mobile drip irrigation vehicle, which uses the water distribution pipe on the frame and the water supply branch pipes arranged along the furrow direction in the field to supply
