Problems solved by technology

[0005] For another example, a negative head irrigation system disclosed in Chinese patent document CN1788542A (patent number: 200510123974.X), a negative pressure automatic irrigation basin disclosed in Chinese patent document CN 201830706U (patent number: 201020528940.5), and a negative pressure automatic irrigation basin disclosed in Chinese patent document CN 101185413A (patent No.: 200710178527.3) discloses a device for automatically controlling the constant soil water potential. The water supply trays or water supply pipes of the above devices are all arranged at the bottom of the root system, and there are no different soil moisture stable supply cultivation devices and realization technologies designed according to the characteristics of the root system of specific crops. The operating method cannot maximize the study of the characteristics of stable water and nutrient supply of different crops, and the structure is complex, the operating cost is high, and the timely demand for water by the root system cannot be met, which affects the normal growth of crops.

Embodiment 1

[0046] A cultivation tank for stably supplying soil moisture for tap root crops, with a structure such as figure 2 As shown, it includes a tank body with an open upper end and a closed lower end. The tank body is made of clay material. The tank body is a truncated inverted conical shape with a wide top and a narrow bottom. The inner diameter of the upper end surface 1 of the tank body is 35cm, and the lower end surface 2 The inner diameter is 30cm, the height between the upper end surface 1 and the lower end surface 2 is 55cm, the thickness of the side wall of the tank body is uniform, and the thickness of the side wall of the tank body is 1cm. Cultivation matrix is ​​filled in the tank body, and columnar microporous pottery clay pipe 4 is arranged on the outer periphery of 10 cm apart from the vertical centerline of the tank body in the tank body. The periphery of the longitudinal center line of the tank body is surrounded by a truncated inverted cone, and the microporous cl...

Embodiment 2

[0051] A cultivation tank for the stable supply of tap root crop soil moisture, the structure is as shown in Example 1, the difference is:

[0052] The inner diameter of the upper end surface 1 of the tank body is 32cm, the diameter of the lower end surface 2 is 26cm, the height between the upper end surface 1 and the lower end surface 2 is 48cm, the thickness of the side wall of the tank body is uniform, and the thickness of the side wall of the tank body is 1.1cm. There are 3 cylindrical microporous clay tubes 4, the columnar microporous clay tubes extend from the upper end of the cultivation tank to the bottom of the cultivation tank, and are distributed with equal radii around the longitudinal centerline of the tank body, and several microporous clay tubes are equally spaced on the same circumference. , the microporous clay tube forms a truncated inverted cone on the periphery of the longitudinal centerline of the tank body, the angle between the microporous clay tube and t...

Embodiment 3

[0055] A cultivation tank for the stable supply of tap root crop soil moisture, the structure is as shown in Example 1, the difference is:

[0056] There are 4 cylindrical microporous clay tubes. The columnar microporous clay tubes extend from the upper end of the cultivation tank to the bottom of the cultivation tank, and are distributed with equal radii around the longitudinal centerline of the tank body. Several microporous clay tubes are equally spaced on the same circumference. , the microporous clay tube forms a truncated inverted cone on the periphery of the longitudinal centerline of the tank body, the angle between the microporous clay tube and the longitudinal centerline of the tank body is 6°, and the distance between the top of the microporous clay tube and the tank body The distance of the longitudinal centerline is 7cm, therefore, the transverse distance between the microporous clay tube and the main root of the crop is 7cm, which is evenly distributed around the ...

Abstract

The invention relates to a cultivation trough for stably supplying soil water for tap root crops. The cultivation trough comprises a trough body with an obconical cutting head, the upper portion of the trough body is wider than the lower portion of the trough body, a plurality of columnar micropore clay pipes similarly parallel to a main root are arranged in the trough body, a turbinate cutting head is defined by the micropore clay pipes on the periphery of the longitudinal central line of the trough body, the micropore clay pipes are all in a hollow column shape, the micropore clay pipes are jointly connected with a water pipe, the water pipe extends out of the trough body and is communicated with an external water supply device, dynamic stable supply of the water needed by the tap root crops is truly achieved, therefore, the drought stress damage of the crops due to the fact that the soil water is in lack and the situation cannot be reflected in time is avoided, water and fertilizer can be efficiently utilized, and waste of the water and nutrients is avoided.

Description

technical field [0001] The invention relates to an irrigation device for maintaining normal growth of crops, in particular to a cultivation tank for maintaining stable water supply of tap root crops, belonging to the field of agricultural science and technology. Background technique [0002] Water is the lifeblood of human beings and a necessary condition for the normal growth of crops. Against the background of global warming, regional droughts and periodic droughts occur frequently, and under the severe situation of increasingly scarce water resources, water conservation and efficient water use are the themes of agricultural production and even various industries around the world. At present, the national agricultural irrigation water is about 350 billion m3 / a, accounting for 90% of the total agricultural water use and 63% of the national total water use. Due to the rapid increase of urban and industrial water use, the proportion of agricultural water use in the country's...
