Embodiment 1

[0026] The reagent used is nano-titanium dioxide (nTiO 2 ): Under the magnification of 200,000 times, the nano-titanium dioxide sample is about 1-80nm and relatively uniform in size. The shape is basically the same, and the surface is nearly round. Add a small amount of water to the hydrophilic nano-titanium dioxide, place it in an ultrasonic machine, and disperse it ultrasonically for 10 minutes under the conditions of ultrasonic power of 500w and ultrasonic frequency of 20kHz, and then make it into a 300mg / L nano-titanium dioxide solution with water.

[0027] The pollen of the male flowers is artificially collected during the flowering period of the litchi, and after the cut spikes are collected, the whole small open (white anther) male flowers are picked. Put the removed male flowers into a test sieve with a diameter of 20 cm and a mesh size of 150-200, place a piece of sulfuric acid paper under the sieve, place it in an oven, and bake and sieve at 28-30°C for 24 hours. Sh...

Abstract

The invention belongs to the technical field of fruit tree cultivation, and particularly discloses a method for improving the quality of litchi chinensis fruits by utilizing nano titanium dioxide. The method comprises the following steps of collecting litchi chinensis pollen, dissolving the litchi chinensis pollen in a nano titanium dioxide solution, and carrying out artificial pollination. The nano carbon dioxide is used for dissolving the litchi chinensis pollen, artificial pollination is carried out, litchi chinensis fruit development can be promoted, litchi chinensis fruit setting stability can be improved, meanwhile, the phenological process can be promoted, and the fruit bearing amount of the whole plant in the mature period can be increased. In the aspect of quality, the single fruit weight, the solid-acid ratio, the edible rate, the vitamin C content, the peel color and luster and the like of litchi chinensis are remarkably improved, and the method provided by the invention is simple in treatment, remarkable in litchi chinensis fruit quality improvement, high in applicability and suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and more specifically relates to a method for improving the quality of litchi fruit by using nano-titanium dioxide. Background technique [0002] Litchi (Litchi chinensis Sonn.) is an evergreen tree belonging to Sapindaceae. It is a subtropical fruit. It is mostly distributed in the southwest, south, and southeast of China. Among them, Guangdong and southern Fujian are the most cultivated. Litchi has high economic value. Planting lychee can promote the healthy development of the fruit industry, and it is also of great value for fruit farmers to get rid of poverty and become rich. The flowering period of litchi is long in spring, and the fruiting period is summer. [0003] my country is the origin and main producing country of lychees. The planting area and output of lychees account for more than 80% and 65% of the world respectively. However, more than 60% of the lychee orchards a...
