Method for decreasing fruit cracking rate of pomegranates

Abstract

The invention relates to the technical field of fruit tree plantation, in particular to a method for decreasing the fruit cracking rate of pomegranates. The method comprises the following concrete steps: spraying an anti-cracking agent once to fruit surfaces 20-25 days before fruit harvest, sleeving fruit peels with a sun-drying bag made by a blue and transparent thin film after spraying, keeping an opening of the sun-drying bag towards the ground after the sun-drying bag sleeving the fruit, spraying the anti-cracking agent every 5 days to fruit surfaces. The raw material of the anti-cracking agent is poisonless and harmless without any impact on quality of pomegranate fruit. Additionally, raw material is obtained easily at low cost. The method for decreasing the fruit cracking rate of pomegranates can be widely applied to the aspect of crack control over pomegranates.

Description

technical field [0001] The invention relates to the technical field of fruit tree planting, in particular to a method for reducing the pomegranate fruit cracking rate. Background technique [0002] The exocarp of pomegranate is dense, the mesocarp is loose, and the endocarp is connected to the ventricle. In the early stage of fruit development, the exocarp has good ductility and is not easy to crack. The fruit is near the ripening stage. Due to the long drought, high temperature, dryness and direct sunlight in summer, The exocarp tissue is damaged, the peel loses its elasticity when it ages, the tannin content increases, the texture becomes brittle, and the meristematic ability becomes weaker. Inconsistent growth speed will cause peel cracking and fruit cracking. Fruit cracking is a common problem in pomegranate production. It can occur from the young fruit stage to the mature stage, especially 10-15 days before the fruit is harvested. The fruit cracking rate is light The a...

[0002] The exocarp of pomegranate is dense, the mesocarp is loose, and the endocarp is connected to the ventricle. In the early stage of fruit development, the exocarp has good ductility and is not easy to crack. The fruit is near the ripening stage. Due to the long drought, high temperature, dryness and direct sunlight in summer, The exocarp tissue is damaged, the peel loses its elasticity when it ages, the tannin content increases, the texture becomes brittle, and the meristematic ability becomes weaker. Inconsistent growth speed will cause peel cracking and fruit cracking. Fruit cracking is a common problem in pomegranate production. It can occur from the young fruit stage to the mature stage, especially 10-15 days before the fruit is harvested. The fruit cracking rate is light The annual rate is generally 3%-10%, and the heavy year is as high as 30%-75%; the fruit is perishable after cracking, cannot be stored fresh, and the commodity value and edible value are reduced or lost

The traditional main measure to solve the problem of pomegranate fruit is to irrigate in time after fruit cracking occurs or when fruit cracking is about to occur. However, when sudden precipitation or irrigation occurs, the root system will quickly absorb water and transport it to the roots, stems, leaves, and fruit organs of the plant, and the growth rate of seeds will be obvious. It is higher than the exocarp that is aging and has basically stopped growing. When the exocarp cannot bear it, it will further cause the peel to crack and cause more serious fruit cracking. However, if you want to prevent pomegranate from cracking, regular watering will cause moisture damage. , reduce fruit sweetness and quality
