By arranging a spring damping wheel and a front car main body and rear car main body detaching and obstacle crossing ratchet, the aims of high-efficiency high obstacle crossing and rapid investigating are achieved, and the car is simple and flexible in structure.

The present invention discloses a method and a system for remote accurate administration of integrated water and fertilizer. The method comprises the steps of: 1, acquiring real-time parameters of a farmland, wherein the farmland parameters include temperature value, humidity value, soil moisture value and flow rate value in an irrigation pipeline; step 2, sending the farmland parameters to a monitoring server through wireless network, calculating irrigation and fertilization strategy and generating an irrigation control signal and a fertilization control signal; and step 3, controlling the flow rate in the irrigation pipeline according to the irrigation control signal, and controlling the flow rate in the fertilization pipeline according to the fertilization control signal. The present invention utilizes wireless communication means to send real-time data of agricultural production site in time to the monitoring server side for data accumulation and remote monitoring on agricultural production site. The method and system guide fertilization and irrigation in agricultural production site, and in particular can achieve finely precise fertilization and irrigation.

A device for decorative purposes, for the vertical cultivation of plants, includes: i) a cultivation support containing a cultivation substrate, and having holes on the front face thereof for the opening out of the above-ground part of the plants, ii) a rigid frame extending in a substantially vertical plane, defining a window in the front face of the cultivation support, and iii) a water reservoir, the cultivation support being placed over the water reservoir, and including at least one hydrophilic wick extending from the cultivation substrate to the water reservoir tank. The cultivation support is hydrated by a continuous supply of water by one or more hydrophilic wicks immersed in the reservoir. It may include an internal framework to give it rigidity and to prevent settling of the substrate in the lower part of the support. A method for obtaining such a plant box is also claimed.
