Embodiment 1

[0028] The preparation of embodiment 1 nanometer carbon dioxide composite reagent

[0029] 1. Irradiation treatment of attapulgite

[0030] Attapulgite (ATP) is a kind of nanoclay because of its nanorod structure, large specific surface area and high adsorption capacity. However, ATP nanorods tend to aggregate together to form bundles, which greatly limits the application of ATP. Therefore, in order to improve the dispersion of ATP to increase its performance, HEEB (high-energy electron beam) irradiation is used to separate ATP from each other to form a network structure, so that more nano-titanium dioxide can be effectively adsorbed on ATP.

[0031] Such as figure 1 , the SEM observation of the attapulgite after irradiation modification by different irradiation doses found that the unmodified attapulgite was densely distributed in bundles, and after increasing the irradiation dose of 10, 20, 30, 40kGy, in After treatment with 30kGy dose, the fascicular distribution is more...

Embodiment 2

[0039] Embodiment 2 Nano-titanium dioxide composite reagent improves the growth of litchi flowers and fruits

[0040]Prepare a certain concentration of nano-titanium dioxide composite reagent (the concentration of the prepared nano-titanium dioxide composite reagent is based on the concentration of nano-titanium dioxide, and the concentration of nano-titanium dioxide is 150, 300, 450, 600, 900mg / L respectively) in the flower buds During the early stage, the whole plant is treated, and the flower spikes are sprayed emphatically, and sprayed until water drops drip. The treatment combination is: (1), the experimental group (clear weather), that is, spraying a certain concentration of nano-titanium dioxide composite reagent: including experimental group 1 to experimental group 5 (the concentration of titanium dioxide in the sprayed nano-titanium dioxide composite reagent is 150 , 300, 450, 600, 900mg / L); (2), the blank control group (clear weather) was sprayed with clear water.

Embodiment 3

[0066] Embodiment 3 Nano-titanium dioxide composite reagent improves the effect of artificial pollination of litchi flowering period

[0067] The present embodiment investigates the effect of nano-titanium dioxide composite reagent on the stigma receptivity of pistil after artificial pollination of litchi, and the specific process is as follows:

[0068] Litchi often has no bees to pollinate during the cloudy and rainy flowering period, and artificial pollination is required. The treatment group prepares pollen liquid pollination with the nano-titanium dioxide composite reagent of certain concentration (in the prepared nano-titanium dioxide composite reagent, the concentration of nano-titanium dioxide is respectively 0, 150, 300, 450, 600mg / L); 150mg / L nano-titanium dioxide composite reagent, the quality of nano-titanium dioxide in 1L nano-titanium dioxide composite reagent solution is 150mg, the quality of attapulgite and biochar are 30mg, 7.5mg respectively; the mass concent...

Abstract

The invention belongs to the technical field of plant cultivation, and discloses a nano-titanium dioxide composite reagent for improving the pollination and fertilization ability of litchi flowering stage, comprising nano-titanium dioxide and an auxiliary agent for improving the adhesion of the nano-titanium dioxide. Nano-titanium dioxide has the ability to improve pollination and fertilization, and has photocatalysis at the same time, so it can increase the photosynthesis of litchi and promote the growth of litchi; the addition of auxiliary agents increases the adhesion of the compound reagent, which makes it easier to enter the plant to play a role, reducing Spraying loss rate improves reagent utilization rate; the use of the nano-dioxidized peptide composite reagent of the present invention can effectively prolong litchi flowering time and male and female flower encounter time, improve pollen germination rate, pollen vigor and stigma receptivity, and promote litchi pollination and fertilization, And it can promote the photosynthetic ability of leaves to increase the accumulation of carbohydrates, enhance the ability of litchi to resist low temperature and rain or high temperature and drought during the flowering period, and increase the fruit setting rate.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a nano-titanium dioxide composite reagent for improving the pollination and fertilization ability of litchi at flowering stage. Background technique [0002] Litchi (Litchi chinensis Sonn.) is an evergreen tree belonging to Sapindaceae. Its flowering period is spring and its fruiting period is summer. Litchi cultivation is mostly distributed in southwest, south, and southeast China, among which Guangdong and southern Fujian are cultivated. It is the most prosperous, and the temperature in spring in Guangdong is unstable, and there are many rainy weather, which makes it easy for litchi to encounter bad weather during the flowering period, such as the influence of continuous rainy weather. The rainy weather is too long during the flowering period of litchi. Pollen is difficult to transfer from male flower to female stigma, which is not conducive to natural pollination. In...
