Problems solved by technology

All these irrigation methods are passive irrigation. Either the irrigation is not timely and the crops suffer from drought, or the irrigation is excessive and the crops are flooded, which seriously affects the yield and quality of the crops, and also causes deep leakage and wastes water resources.

Embodiment 1

[0012] Embodiment 1: As shown in Figures 1-1 and 1-2, the micro-flow continuous irrigation tube is formed by a tubular 1 with a certain length and diameter and filled with water. On one side of the inner cavity of the tube 1, there is a tube 1 A part of the tube wall itself is tightly bonded together by physical or chemical methods. Discontinuous slender strips of different lengths. 2 Many very thin filaments that are equal in length to the same tube and have a diameter smaller than that of the tube. A wick-like slender line 4 is formed. Water enters the slender line 4 through the water inlet hole 5 formed by discontinuous slender strips 2 of different lengths. The holes 3 flow into the soil to irrigate the crops.

Embodiment 2

[0013] Embodiment 2: As shown in Figures 2-1 and 2-1, the micro-flow continuous irrigation tube is formed by a tubular 1 of a certain length and diameter and filled with water. On one side of the inner cavity of the tube 1, there is a tube 1 A part of the tube wall itself is tightly bonded together by physical or chemical methods. Discontinuous slender strips of different lengths 2 Many very thin filaments with a certain length and a diameter smaller than the diameter of the tube 1 sealed A wick-like slender line 4 is formed. Water enters the slender line 4 through the water inlet hole 5 formed by discontinuous slender strips 2 of different lengths. The holes 3 flow into the soil to irrigate the crops.

Abstract

The invention relates to the natural and bionic irrigating, belonging to the water industry field, especially relating to a bionic irrigating machine which can provide water in accordance with the plant growing need for the whole day in the agricultural saving-water irrigation. The invention breaks the traditional intermittent rotation irrigation idea, making use of the physiological characteristic of the crop, the mechanism of the blood supply by the human capillary vessel to the cell and the principle of capillary absorbent, when the crop needs little water, the water entering to soil through line 4 is little; when the crop needs much water, the water entering into soil through line 4 is much, which on the whole reaches a optimum equilibrium state.

Description

technical field [0001] The micro-flow continuous irrigation pipe of the present invention belongs to the field of hydraulic engineering, and particularly relates to a water-saving irrigation pipe with biological natural characteristics that can meet the needs of crop growth all the time and keep the soil moisture in a dynamic equilibrium state that is most suitable for plant growth. irrigator. Background technique [0002] Water is a necessary condition for agricultural development, and the problem of water shortage has become a bottleneck restricting the sustainable development of the world economy. In our country, this problem is particularly prominent. Vigorously advocating and implementing agricultural water-saving irrigation and improving the ecological environment have become the basic national policies of our country. The current agricultural irrigation mainly includes flood irrigation, sprinkler irrigation, micro-sprinkler irrigation and drip irrigation. All these i...
