Background

Along with the increase of industrial water and domestic water consumption, the agricultural water consumption is in the trend of reducing year by year, great impact is brought to the production of rice crops with larger water consumption, and the global temperature is continuously increased, the water consumption of the rice is obviously increased in the future, so the current situation aggravates the water resource crisis in the rice production, and the water-saving high-yield rice is the precondition guarantee of the green production of the rice in the future.

Under the condition of water-saving cultivation, the components and the effectiveness of the water, the fertilizer, the pesticide and the heavy metal elements in the root zone are greatly changed compared with the traditional cultivation, but the cognition of the growth and the development of the rice on the environment response mechanism of the water-saving root zone is still needed to be deeply researched. At present, the most common means for developing water-saving high-quality high-yield cultivation research of rice to observe growth and development characteristics of rice is a barrel cultivation method, the method has the advantages of strong controllability and convenience in data observation and recording, and the method is commonly used for exploring in the aspect of a water-saving cultivation mechanism of rice and constructing a theoretical system. However, in the existing water-saving research, the rice barrel planting itself has a large test error, which restricts the research breadth and depth expansion of root areas, and the problems of heavy labor intensity of the barrel planting research are more obvious, specifically including:

(1) the test error is one, and the temperature in the barrel is out of control. Compared with the traditional irrigation system, the water content of the soil in the water-saving cultivation mode is inconsistent, so that the temperature of a root layer is obviously different, and particularly, the influence of the environmental temperature (air temperature) on the local temperature is far greater than the temperature difference of the root zone caused by the difference of the soil moisture on the barrel wall and the bottom, so that the water-saving cultivation mode is an obvious test error. The wall and the bottom of the lower barrel for water-saving cultivation are more easily affected by air temperature to generate high (low) temperature stress, and the root growth of the area is changed in an uncontrolled manner;

(2) and (5) test errors are two, and root growth in the barrel is blocked. At present, the depth of a part of barrel cultivation is insufficient, the diameter of the barrel is small, root systems on the barrel wall and the barrel bottom grow, and physical root resistance is formed;

(3) and test error is three, and the soil in the barrel is relatively thick. The rice field soil with different soil textures is difficult to simulate for loading; the test errors and the defects of the device equipment bring great uncertainty to the establishment and the creation process of a theoretical system;

Most barrel planting devices are not provided with a drainage system, and are not favorable for the migration research of water, fertilizer, medicine, heavy metal elements and the like in a root zone particularly in the aspect of layering; in addition, the current barrel planting device is difficult to accurately represent and quantify the leakage amount, the intertriginous evapotranspiration amount and the crop transpiration amount, and the defects restrict the excavation of a new water-saving high-quality high-yield mechanism and a new way of rice.

(5) The labor intensity is high. If the generation of a first test error is avoided, the barrel can be buried in the field, but the method has high labor input intensity and brings inconvenience to production management and data acquisition. In addition, a large amount of manpower is needed in irrigation and daily management of the barrel planting, the labor input cost is high, and the scientific research output efficiency is slowed down. Therefore, the development of a simple device for water-saving cultivation of rice is urgently needed to enrich and correct a theoretical system for regulating and controlling the yield and quality of rice by soil moisture.
