Fruit maturity evaluating method based on maturation rule

Abstract

The invention belongs to the technical field of agricultural product processing, and concretely relates to a fruit maturity evaluating method based on a maturation rule. The method is characterized in that the variation rule of characteristic physicochemical indexes such as fruit hardness, pericarp color, pericarp chlorophyll content, fruit soluble solid content, vitamin C content and the like during maturation of fruit is researched according to the effective accumulated temperature during maturation of fruit, and a maturation model of fruit is established based on the variation rule; and any one physical and chemical index covered by the model is selected, and the maturation degree of fruit is defined as a percentage of the variable quantity of the index during maturation accounting for the total variable quantity in the whole maturation phase. The method employs effective accumulated temperature as the research base and performs quantitative evaluation on the fruit maturation degree, also establishes a mathematical relationship between the fruit maturation effective accumulated temperature and the physical and chemical indexes during maturation by utilizing the maturation degree, finishes mutual prediction among the maturation effective accumulated temperature, the maturation degree and the physical and chemical indexes at the maturation period, and helps to guide picking of fruit according to different processing manners of harvested fruit.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and mainly relates to a maturity evaluation method based on fruit ripening law. Background technique [0002] In terms of fruit ripening law and maturity evaluation, domestic and foreign scholars have involved many fruit varieties, such as citrus, apple, nectarine, peach, Fengshui pear, apricot, etc., but the fruit maturity has not been quantitatively determined. As a result, the evaluation of maturity is mainly based on qualitative descriptions based on indicators such as color, quality, and smell. Research is also based on this qualitative classification method, and the repeatability of experiments is poor. This phenomenon also exists in the actual production of fruits. National standards and industry standards mostly stipulate the maturity of fruits by how ripe or the specific time. For example, the harvest of Korla fragrant pears should be carried out in the middle and...

Problems solved by technology

However, the ripening law of fruit is different from that of rice. At present, there is still a lack of reports on the research and evaluation of maturity of fruit crops based on accumulated temperature at home and abroad.

At present, the traditional method is to judge the maturity and picking time based on planting experience and visual estimation, so there will inevitably be differences in subjective judgments, which will affect the rationality of picking time
