AI Technical Summary

Problems solved by technology

The placement of sensors (i.e., monitors) in the existing drip irrigation system and infiltration irrigation system is mainly based on a single monitoring of the gravity effect, that is, the sensor and the dripper are on the same vertical line, and the nutrient distribution area of ​​the crop root system and the soil are not fully considered. The relationship between moisture, when the sensor under the vertical dripper detects that it is in a state of water saturation, the soil moisture in other parts of the rhizosphere is often still in an unsaturated state
Therefore, it is not conducive to the growth and development of the secondary root system of crops
In addition, the existing drip irrigation system and infiltration irrigation system can only do when to start watering (including ordinary water, and fertilizers can also be included), but how much water to make the vertical and horizontal nutrient circles of water nutrients necessary for crops penetrate The method of drip infiltration control within the range of crop rhizosphere has not been reported yet

Embodiment Construction

[0049] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] In the following description, some exemplary embodiments of the present invention are described by way of illustration only, and those of ordinary skill in the art will recognize that, without departing from the spirit and scope of the present invention, the The described embodiments can be modified in various ways. Accordingly, the drawings and description are merely illustrative in nature and are not intended to limit the scope of the claims.

[0051] Here are a few commonly used nouns in this field:

[0052] Capillary force: refers to the force of cohesion, adhesion and surface tension between soil particles to overcome gravity and move water upward and horizontally.

[0053] Field water holding capacity: Field soil has a maximum water holding capacity. This index is collectively referred to as field water holding capacity...

Abstract

The present invention relates to a drip seepage control method, comprising the following steps: installing a first moisture monitor and a second moisture monitor respectively at a first vertical distance d1 and a second vertical distance d2 below the soil, wherein, d1

Description

technical field [0001] The invention relates to a drip seepage control method and a drip seepage control system. Background technique [0002] At present, both water-saving irrigation technology and irrigation supporting products are research hotspots in recent years. So far, the development has gone through from agricultural water-saving technology 2.0 products to 4.0 products, including drip irrigation, seepage irrigation, sprinkler irrigation, etc., but mainly Mainly drip irrigation and seepage irrigation. [0003] Secondly, based on the different control methods, it includes: such as gravity drip irrigation system, solar drip irrigation system, manual control drip irrigation system, frequency conversion drip irrigation system, etc. These control methods and systems are controlled by detecting soil moisture content and intermittent irrigation. In the setting of parameters, traditional empirical values ​​are adopted. Although they can achieve the superficial purpose of wa...
