Soil plowing detection and judgment method and system

Abstract

The invention relates to the technical field of agricultural intelligent irrigation, and provides a soil plowing detection and judgment method. The method comprises the following steps: acquiring the volumetric water content of farmland soil with a preset depth in the irritation process, recording the acquisition time, determining the effective time quantum from irritation beginning to the change of the volumetric water content of the farmland soil according to the volumetric water content of the farmland soil and the acquisition time, and judging that soil plowing is needed if the effective time quantum is longer than a threshold time; and calculating the water seepage speed of the farmland soil in the predetermined time quantum after the change of the volumetric water content of the farmland soil if the effective time quantum does not exceed the threshold time, obtaining the compactness of the soil according to a relationship between the known water seepage speed and the compactness of the soil, and judging that the soil plowing is needed when the compactness of the practical soil is greater than the compactness required by crops in the soil. The soil plowing detection and judgment method allows soil plowing or not to be rapidly and effectively judged.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a method and system for detecting and judging soil turning. Background technique [0002] During the planting or growing of crops, it is often necessary to turn the soil. The compaction degree of the farmland soil is closely related to the growth of the crops. The high compaction degree is not conducive to water penetration and the growth of the crops. It is necessary to turn the soil in time to ensure the proper growth environment of the crops. . However, the soil turning process is labor-intensive and takes a long time. Most people judge whether the crop planting area needs to be turned over according to the existing experience, and the error of manual judgment is relatively large, which is not conducive to the growth of crops. [0003] At present, in terms of domestic agricultural intelligence, there are wired pressure sensor terminal equipment to collect soi...
