Management method for improving fruit quality of winter jujube

Abstract

The invention belongs to the technical field of winter jujube cultivation, and particularly relates to a management method for improving fruit quality of winter jujube. The method comprises the stepsthat when the number of flowers of a jujube deciduous spur is 5-8, magnetic water or regulation water is sprayed from eight o'clock to nine o'clock every morning, and it is just needed that the moderate quantity of the magnetic water or regulation water meets the condition that water on leaves drips; the magnetic water and regulation water are alternately sprayed on alternate days, and the total spraying time is 16-20 days. Compared with the prior art, the management method for improving the fruit quality of the winter jujube has the advantages that the magnetic water and the regulation waterare alternatively sprayed on the winter jujube, so that a certain of humidity can be ensured in a flowering phase, pollen germination and pollen tube elongation are promoted, the pollination fertilization quality is improved, hydropenic flowers are reduced, the content of anthocyanin, vitamin C and like is effectively ensured, and the fruit quality of the winter jujube is improved while the fruitsetting rate of the winter jujube is improved, thereby ensuring the yield of the winter jujube.

Description

technical field [0001] The invention belongs to the technical field of winter jujube cultivation, and in particular relates to a management method for improving the fruit quality of winter jujube. Background technique [0002] Dongzao is a kind of late-maturing, fresh-eating, high-quality jujube germplasm, rich in 19 kinds of amino acids and multivitamins needed by the human body, and has high therapeutic value and health care effect. Because of its good quality, it is widely planted and promoted. At present, due to the application of a large amount of chemical agents in the planting process, the quality of winter jujube has declined. With the development of the national economy and the improvement of people's living standards, the current consumption type is gradually changing from quantity consumption to quality consumption. The impact of food on human health People pay more and more attention to it, and consumers have higher and higher requirements for fruit quality. At t...

[0002] Winter jujube is a late-maturing, fresh-eating, high-quality jujube germplasm, rich in 19 kinds of amino acids and multivitamins needed by the human body, and has high therapeutic value and health care effect. Because of its good quality, it has been planted and promoted on a large scale. At present, due to the application of a large amount of chemical agents in the planting process, the quality of winter jujube has declined. With the development of national economic construction and the improvement of people's living standards, the current consumption type is gradually changing from quantity consumption to quality consumption. The impact of food on human health People pay more and more attention to it, and consumers have higher and higher requirements for fruit quality. At the same time, the yield of winter jujube is also the direction of continuous research. In the existing technology, the use of magnetized water to irrigate winter jujube plants can increase the chlorophyll content of leaves. , fresh quality and thickness of leaves, effectively promote the growth and development of branches and leaves of winter jujube, improve tree vigor and fruit quality, the reason why magnetized water irrigation can increase production and income is mainly because magnetized water is affected by the magnetic field, and the electrons in the water molecules obtain magnetic moments , increase the dipole moment of the water molecule, deform the water molecule, increase its polarity, enhance the degree of hydration, and increase the electric power of the salt, creating favorable conditions for plants to absorb nutrients. It can promote the growth of roots and increase the utilization rate of nutrients in the soil. After using magnetized water to irrigate winter jujube, the trace elements in leaves of winter jujube increase to a certain extent, and the reducing sugar and nutrients in the fruit have a certain increase, but the increase is not obvious. little effect on the fruit set rate
