Embodiment Construction

[0011] For afforestation and sand control in arid areas where well irrigation is used as the water source, when applying water-saving irrigation technology, special planning and design must be carried out for water source balance, headworks, and layout of pipe network systems. According to the purpose of afforestation and sand control, the corresponding Tree species, taking the construction of mobile sand dunes on both sides of railways and roads in the periphery of oasis and sandy areas, and the construction of economic forests in well-irrigated areas in sandy areas as examples, the main technical measures adopted are as follows:

[0012] 1. Water source balance: according to the water output of a single well (m 3 / h) and water utilization rate, according to the daily water consumption per unit area (mm / d) or the daily water consumption per plant (mm / plant) in the hottest month when the forest is formed, design the irrigation volume, irrigation cycle and rotation irrigation ar...

Abstract

A drip irrigation technique for the shelter forest of sandy field features that the consumed water volume, irrigation period and rotation irrigation regions are designed according to the summer season, its system is composed of water pump, filter system, fertilizer applying and irrigating unit and irrigation network composed of trunk, branch tubes, and capillary tubes, and proper dripping head, arranging method and irrigation rule and chosen reasonably.

Description

technical field [0001] The invention relates to the technical field of tree planting and desert control, in particular to an application technology of drip irrigation for sand shelterbelts. Background technique [0002] Drip irrigation technology is a water-saving irrigation technology imported from Israel in my country. It is mainly used in agricultural production. The irrigation of sandy shelterbelts in my country basically uses channel irrigation. Only a small part of channel irrigation uses channel anti-seepage technology. Leakage phenomenon Very serious; irrigation and afforestation requires leveling the sandy land, making irregularities or ditches, and adopting canal irrigation. The water source needs to reach the forest land through channels. The water seepage and evaporation losses in this process are very large, and the young forests of the new afforestation are often lost due to the loss of water. Less than proper irrigation leads to lower survival rate of afforestat...
