Embodiment 1

[0030] This embodiment provides an irrigation test platform oriented to precision agriculture, with features such as Figure 1-2 The shown structure includes several platform bodies, a data acquisition module, a ZigBee wireless communication module 7, a main control module and a monitoring center. The specific structure of the test platform of this embodiment is described in detail below with reference to the accompanying drawings.

[0031] The platform main body includes a rotating test table 1 and its bracket, an irrigation system 2 and a stepping motor 6. The rotating test table 1 is circular and is used to carry the test crops 10, and is driven to rotate by the stepping motor 6. The system 2 is used to irrigate the test crop 10, and includes a water tank 21 and a pump. The water tank 21 is connected to the test crop 10 through the pump, so that the water in the water tank 21 is pumped into the soil of the test crop 10 to realize irrigation.

Abstract

The invention discloses an irrigation test method oriented to fine agriculture and a test platform thereof. The test platform includes a platform main body, a data acquisition module, a wireless communication module, a main control module and a monitoring center. The steps of the test method include: Crops in different growth stages are placed on the test platform, irrigated with different irrigation modes, and a multi-level and multi-objective fuzzy evaluation model of growth stages, irrigation modes, leaf stretch index and environmental factors is established to scientifically guide crop irrigation. The present invention comprehensively considers the soil moisture content, the environment and the most sensitive part of the crops that affect the growth of crops, and uses the Internet of Things technology to provide an irrigation test method and its test platform for precision agriculture, which is realized through an operable real-time online monitoring method. The mesoscopic investigation of the stretching degree of crop leaves, the study of the influence mechanism between the stretching degree of crop leaves and soil moisture content, air temperature and humidity, and irrigation amount, further reveals the growth status of crops.

Description

technical field [0001] The invention relates to the technical field of crop greenhouse cultivation and breeding, in particular to a precision agriculture-oriented irrigation test method and a test platform thereof. Background technique [0002] At present, the indicators of water demand for crop growth in precision agriculture can be roughly divided into three types. One is the soil as the object, and the soil water potential or soil moisture content is often used to judge the water demand of crops. The advantage is that it is relatively stable and less affected by the environment. But it is an indirect indicator of crop growth after all, and the reflection is relatively slow, lag and low in precision. The second category takes the environment as the object, and mainly uses the weather forecast to estimate the water demand of crops. However, crop water requirements are not only affected by the environment, but also by other and the crops themselves. At the same time, thi...
