Spark based precision irrigation method of MLR-model Red Fuji apple trees

Abstract

The invention provides a spark based precision irrigation method of MLR-model Red Fuji apple trees and establishment of MLR precision irrigation model and a real-time irrigation decision method for Red Fuji apple trees in Jiaodong Peninsula. The establishment of the MLR precision irrigation model includes: producing a data set of factors affecting water demand of the Red Fuji apple trees; buildinga distributed system, deploying a Spark cluster, and performing assessment to complete the irrigation demand analysis; the real-time irrigation decision method includes: a lower-computer ARM microprocessor using a sensor to acquire environmental information; performing data cleaning and normalization; performing real-time communication with the upper-computer website through a GPRS module; Sparkperforming real-time data processing to generate decision values; if the water threshold is reached, carrying out irrigation according to the established irrigation quota, otherwise, performing no processing. With the method, intelligent irrigation and closed-loop control of the Red Fuji apple tree planting in Jiaodong Peninsula are realized, the irrigation precision can be improved, and the agricultural production can be optimized.

Description

Technical field [0001] The invention relates to the technical field of agricultural production machine learning and precision irrigation, in particular to a precision irrigation method of a Red Fuji apple tree based on an MLR model of Spark. Background technique [0002] Water is an important factor in the growth and development of apple trees, and fruit trees are very sensitive to water requirements during the growth process. According to analysis, the moisture content during the germination period is good, which is beneficial to the buds and shoots. The soil moisture content should reach 70% to 80% of the field water holding capacity. The soil moisture requirement during the flowering period is sufficient, which is conducive to flowering and fruit setting. The soil water content should reach 60% to 70% of the field water holding capacity; the new shoot growth, young fruit development and fruit expansion stage have sufficient water, the fruit develops fast, but the water supply ...

AI Technical Summary

Problems solved by technology

Although a lot of research has been done at home and abroad, the types of irrigation models are limited, and the research objects are concentrated on field systems. There are few studies on fruit trees, and there is no irrigation model suitable for red Fuji fruit trees in Jiaodong Peninsula. Therefore, research This field has great economic value and prospects
