Problems solved by technology

If the index is set too high, it will increase the evaporation between trees and the extravagant transpiration of crops, and reduce the water use efficiency
If the index is set too low, it may cause insufficient water supply for a certain period of time, which will affect the normal growth of crops

Embodiment Construction

[0018] Such as figure 1 Shown, the control method that the present invention carries out irrigation according to crop water shortage adversity physiological response is as follows:

[0019] First, install the plant stalk diameter variation transmitter 1 on the crop stalk, rely on the plant stalk diameter variation transmitter 1 to collect the daily variation value of the stalk diameter, and install a light transmitter above the crop stalk A device 2 is used to collect the daily cumulative value of solar radiation, and a soil moisture sensor transmitter 3 is installed at the root of the crop to collect the soil moisture content of the root of the crop.

[0020] Secondly, input the output data of the plant stalk diameter variation transmitter 1, the light transmitter 2, and the soil moisture sensor transmitter 3 into the crop stalk diameter variation index calculation and water shortage analysis unit 4, and the crop The stalk diameter change index calculation and water shortage...

Abstract

This invention relates to the control method and devise for the irrigation on it's stem, and fix the optic inductor on the top of stem, and install the inductor on the root of the plants to test the water in soil, and then, put the data get from diameter size measure equipment optic inductor water test inductor into the diameter variety index compute unit and water analyze units. Compare the changed quantity and the diameter variety index, compare the sun radiation addition per day and average sun radiation j n season, compare the water amount in soil, and lest water amount in soil, then to decide whether to five the irrigation. Consist the diameter size measure equipment optic inductor, diameter size measure equipment optic inductor, water test inductor, diameter variety index compute unit and water analyze units, irrigation equipment control unit, alternating pump deductor and pipe electro magnetism value, and we get the irrigation control device. This device can feed back the information of water needed by plants, saved water shortage, get more compensation for the plants and stimulate the root of plants is good to the growth of plants.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural irrigation, and in particular relates to a method and a device for controlling irrigation according to the physiological response of crops to water shortage and adversity. Background technique [0002] The lack or excess of water has an important impact on the plant metabolic system, especially the lack of water has a great impact on the production of crops. At present, automatic irrigation control devices all use soil water content as the control index of crop irrigation, and control the soil water content to meet the physiological and ecological water demand of crops. According to experience, when the relative water content of crop soil is 60% (accounting for field water capacity %), it is light drought and needs irrigation; when it drops to 50%, it is severe drought, which will seriously affect crop growth and yield formation; when it reaches 80%, it is Appropriate water; 85% is the uppe...
