Novel rice plant potting system

Abstract

The invention relates to a novel rice plant potting system. A culturing bucket comprises an inner cylinder and an outer cylinder, wherein the inner cylinder is sleeved by the outer cylinder; a detection device is placed in the inner cylinder; a root fixing bracket is further mounted in the inner cylinder; a water inlet and a water outlet are respectively formed in the upper end of the outer cylinder; a water source bucket is communicated with the water inlet through a pipe; a connection port is further formed in the bottom of the outer cylinder; the detection device comprises a gas collection device, a soil temperature monitor, a soil moisture monitor and a water level monitor; the water level monitor is mounted between the inner cylinder and the outer cylinder. According to the invention, the water level monitoring device is introduced, to strictly control the depth of water in each processed rice plant field and to achieve the free water supply and drainage during rice plant cultivation; the quantitative application of fertilizers is achieved to solve the problem of leaching loss of nitrogen-potassium fertilizer and other instant fertilizers during potting; an accurate quantitative research can be performed on the water and fertilizer management for the rice plant field; and the continuous monitoring for soil moisture and temperature is achieved.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a novel rice pot planting system. Background technique [0002] When performing pot experiments on rice, test pots with drainage holes at the bottom or buckets with no drainage holes at the bottom are commonly used instead. The main problems in the current pot experiment of rice include: [0003] 1) During the entire growth period of rice, several drying and flooding processes are required, and it is difficult for ordinary test pots to accurately control and maintain the flooding water level during the flooding period of the paddy field. The leaching loss of nitrogen fertilizer is easily caused by conventional watering methods, and it is difficult to conduct quantitative research on nutrient elements in pot experiments. The method that replaces with bucket then drainage is inconvenient, is difficult to realize the drying process of paddy field. [0004] 2) Or...
