Novel fruit thinning method

Abstract

The invention discloses a novel fruit thinning method. A near-infrared spectroscopy is utilized to scan sucrose solutions of different concentrations, characteristic wavelengths are extracted, a mathematical equation of sucrose concentration and near infrared spectrum reflection strength under the characteristic wavelengths is established, and thus a method for detecting content of sucrose in carpopodium of a fruit is obtained by adopting the near-infrared spectroscopy. The near-infrared spectroscopy is adopted to scan the carpopodium of the primarily-born fruit on the plant to obtain near-infrared spectrum data, and the concentration of the sucrose in the carpopodium is obtained according to the mathematical equation in the first step; the concentration of the sucrose in the carpopodium is compared with the concentration of sucrose in carpopodium of an adjacent fruit, and the fruit with the lowest concentration of the sucrose in the carpopodium is selected to thin fruits. According to the method, the fruit thinning effectiveness can be improved, and the method can be applied to fruit thinning of tomatoes, sweet peppers and eggplants and the like.

Description

technical field [0001] The invention belongs to the field of protected horticultural cultivation, and in particular relates to a technology for accurately locating the position of greenhouse tomato vegetables and fruits by using near-infrared spectrum. Background technique [0002] Protected horticulture has developed rapidly in my country, from 10,300 hectares in 1982 to 4.109 million hectares in 2015, ranking first in the world in total area. At present, tomato pruning technology in protected cultivation in my country is mainly transplanted from field cultivation technology, that is, through the experience of the producer, the fruit that needs to be removed is selected for vegetable and fruit. This method requires the producer to have a deep understanding of the growth and development of tomato fruit. , and is subjective and arbitrary. However, there are many differences between field tomato cultivation and facility tomato cultivation, which are mainly reflected in the fol...

Problems solved by technology

But there are the following deficiencies: First, the fruit growth rate needs to be measured and acquired, which is difficult to predict in advance and has a hysteresis

In different growth stages, there are great differences in fruit growth rate, which makes it difficult to accurately calculate the fruit bank strength
