Description

Technical Field

[0001] The invention relates to the technical field of fruit planting irrigation, in particular to a drought-resistant and water-saving drip irrigation system for pitaya in tropical areas. Background Art

[0002] Pitaya is a tropical and subtropical fruit with an optimum growth temperature of 25-35℃. It likes light and tolerates shade, heat and drought, fertilizer and barrenness. It grows rapidly in a warm, humid and well-lit environment. Pitaya has won the favor of consumers around the world for its bright skin and sweet flesh. Tropical regions usually have ample sunshine, high temperature and high humidity, which provide an ideal environment for the growth of pitaya. Sunlight is the key to photosynthesis of pitaya, while high temperature promotes the rapid ripening of the fruit and the accumulation of sugar, ensuring sufficient water supply during its growth.

[0003] As the impact of global climate change becomes increasingly significant, tropical regions are also facing an increasingly severe water shortage problem. Especially in the field of pitaya cultivation, although this tropical fruit is adapted to hot and humid environments, its growth and yield may be affected in dry seasons or areas with limited water sources. At present, pitaya cultivation in tropical regions mainly relies on traditional irrigation methods, such as ground irrigation and flood irrigation:

[0004] 1. Flood irrigation: In areas with abundant water resources and flat terrain, the whole garden is often irrigated. However, this irrigation method has a certain degree of damage to the soil structure, is labor-intensive and time-consuming, and is not economical;

[0005] 2. Fence irrigation: Repair tree trays based on plant units, or make long furrows along the tree rows, and guide water into the tree trays or furrows during irrigation. This method saves water, is easy to manage, and is widely used, but it will also damage the soil structure of the tree furrows and cause the death of absorbing roots.

[0006] With the development of agricultural technology, how to improve irrigation technology, improve water resource utilization efficiency, and reduce management costs is an important direction for the pitaya planting industry in tropical areas to develop drought-resistant and water-saving drip irrigation systems. Therefore, the present invention provides a tropical pitaya drought-resistant and water-saving drip irrigation system to solve the problems raised in the above background technology.
