Abstract

The bionic irrigation device generally relates to water irrigation field, especially relates to a biologic watering device which could supply with water the whole day according to the need of the crops in the agricultural water-saving irrigation. The invention breaks through the traditional conception of intermittent irrigation, which takes full advantage of physiologic character of the crops, the principal that the cell is supplied with blood through the capillary blood vessel and the theory that capillary absorbs water, the amount of water feeding into the soil through the slight threads decrease when the amount of water required by the crops fall down; on the other hand, the amount of water feeding into the soil through the slight threads rise when the amount of water required by the crops increase, thus the most suitable balance stage will be reached.

Description

自然仿生灌技术领域 Natural bionic irrigation

本发明的自然仿生灌属于水工领域，尤其涉及农业节水灌溉中能全天候地根据作物生长的需要，使土壤水份始终处于最适宜植物生长的动态平衡状态下的具有生物自然特性的的灌水器。背景技术 The natural bionic irrigation of the invention belongs to the field of hydraulic engineering, and particularly relates to the irrigation of biological water-saving irrigation in an all-weather manner according to the needs of crop growth, so that the soil moisture is always in the most suitable state of plant growth dynamic balance. Device. Background technique

水是农业发展的必要条件，缺水的问题己经成为制约世界经济可持续发展的瓶颈。在我国，这个问题尤其突出，大力提倡和实施农业节水灌溉、改善生态环境己成为我国的基本国策。当前的农业灌溉主要有大水漫灌、喷灌、微喷灌和滴灌等形式，所有这些灌溉方式在农业大面积使用时都是间歇式轮灌灌溉方式，及根据经验感觉作物需要水就开始灌水或用专用仪器进行测量，测量显示缺水，就开始灌水。所有这些灌水方式，都是被动式的灌溉，要么灌水不及时，使作物受旱，要么灌水过度，使作物受涝，严重影响了作物的产量和品质，还会造成深层渗漏，浪费水资源。本发明突破了这种传统意义上的灌溉理念，充分利用作物自身的生理特性，利用人体毛细血管为细胞供养的机理和毛细管吸水原理，实现了全天候根据作物的生长需要，动态平衡供水的全新的灌溉理念。发明内容 . 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 China, this problem is particularly prominent. It is a basic national policy of China to vigorously promote and implement agricultural water-saving irrigation and improve the ecological environment. The current agricultural irrigation mainly includes flood irrigation, sprinkler irrigation, micro-sprinkler irrigation and drip irrigation. All of these irrigation methods are intermittent irrigation with irrigation in large areas of agriculture, and it is empirically felt that crops need water to start irrigation or use. The special instrument is used for measurement, and the measurement shows that there is water shortage, and the water is started. All of these irrigation methods are passive irrigation, or the irrigation is not timely, the crops are affected by drought, or the irrigation is excessive, the crops are affected, which seriously affects the yield and quality of the crops, and also causes deep leakage and wastes water resources. The invention breaks through the irrigation concept in the traditional sense, fully utilizes the physiological characteristics of the crop itself, utilizes the mechanism of human capillaries for cell feeding and the principle of capillary water absorption, realizing the all-weather growth of the crop according to the growth needs of the crop. Irrigation concept. SUMMARY OF THE INVENTION

本发明在于提供一种利用作物自身的生理特性，结合人体供血机理及毛细管吸水原理，实现全天候根据作物的生长需要，高效供水的生物型灌水器。 The invention provides a bio-type water emitter which utilizes the physiological characteristics of the crop itself, combines the blood supply mechanism of the human body and the principle of water absorption of the capillary tube to realize the high-efficiency water supply according to the growth demand of the crop all day.

本发明是这样实现的：自然仿生灌灌水器是由一定长度和直径的管状物形成输水通道，在管的内腔的一侧，封有同管的长度相等、直径小于管的直径的很多很细的丝状物构成的类似灯芯状的细长线，以及细长线同管的内腔相连的一定数量的进水通孔和细长线同管的外部相通的一定数量的出水通孔。细长线封在管的内腔的一侧是靠管自身的一部分管壁利用物理或化学的方法紧密结合在一起的长短不一的不连续的细长条实现的。在管的内腔充满水后，水通过细长线同管的内腔相连的一定数量的进水通孔进入到细长线里，细长线里的水在毛细管吸水原理的作用下通过细长线同管的外部相通的一定数量的出水通孔流出，进入土壤，灌溉作物。 The invention is realized as follows: The natural bionic irrigation water irrigator is formed by a tube of a certain length and diameter, and on the side of the inner cavity of the tube, the length of the same tube is equal, and the diameter is smaller than the diameter of the tube. A filament-like elongated wire of very fine filaments, and a number of inlet channels and a plurality of outlet openings for the elongated line to communicate with the exterior of the tube. The elongate wire is sealed on one side of the lumen of the tube by a length of discrete strips of varying lengths that are physically or chemically bonded together by a portion of the tube wall itself. After the inner cavity of the tube is filled with water, the water enters the elongated line through a certain number of inlet holes through which the elongated line is connected to the inner cavity of the tube. The water in the slender line flows out through the elongated line through a certain number of outlet holes that communicate with the outside of the tube under the action of the capillary water absorption principle, entering the soil and irrigating the crop.

由于采用了上述方案，在供水过程中受作物根区水势影响，当作物需水少时，由细长线进入土壤的水就比相对少；当作物需水多时，由细长线进入土壤的水就相对多，达到供需的最佳平衡状态，实现按需供水的目的。附图说明 Due to the above scheme, it is affected by the water potential of the crop root zone during the water supply process. When the crop requires less water, the water entering the soil by the slender line is relatively less; when the crop requires more water, the water entering the soil by the slender line is relatively More, to achieve the best balance between supply and demand, to achieve the purpose of on-demand water supply.
