Non-destructive determination method for watermelons spindling seedling

Abstract

The invention discloses a non-destructive determination method for a watermelons spindling seedling. The method is used for judging the excessive growing seedlings and the normal seedlings of the watermelons, firstly, phenotypic parameters of the watermelon plug seedlings are obtained, then phenotypic data obtained through measurement are preprocessed, measurement errors are compensated, then the excessive growing value Z is obtained, finally, the excessive growing seedlings and the normal seedlings are judged according to the excessive growing value Z, and a specific judgment rule is provided. According to the method, the defects of manual screening can be overcome through visual quantitative analysis of data. The established spindling seedling nondestructive determination rule has strong applicability and can be used for watermelon seedlings in various growth periods. The phenotype data of the watermelon seedlings can be obtained through nondestructive measurement modes such as image recognition, so that large-scale intelligent detection of the seedlings is realized. The workload of artificial breeding screening can be reduced, and the production cost is remarkably reduced.

Description

technical field [0001] The invention belongs to the field of agricultural automation, and in particular relates to a non-destructive judgment method for watermelon leggy seedlings. Background technique [0002] Watermelon occupies a very important position in the world's horticultural production. Since the 1990s, the watermelon industry has entered a stage of rapid growth, and the area of ​​watermelon planting has continued to increase. my country has become the world's largest producer and consumer of watermelon, with an annual output of over 60 million tons of watermelon, and the annual demand for watermelon seedlings is as high as tens of billions. Seedling production enterprises mostly use porous one-piece plug trays as containers for seedling cultivation, and replace soil with artificially mixed substrates. This method saves land resources, is suitable for large-scale production in factories, and is convenient for mechanized operation. However, in the actual productio...

Problems solved by technology

[0003] In the process of raising watermelon seedlings, the external morphological indicators such as plant height and stem thickness are generally observed, and whether the watermelon seedlings are overgrown is judged through empirical judgment. Subjective judgment and poor intuition are not conducive to large-scale detection of seedlings.
