A kind of compound and application thereof for improving pollination and fertilization ability of litchi

Abstract

The invention belongs to the technical field of plant cultivation, and in particular relates to a compound for improving the pollination and fertilization ability of litchi at flowering stage and its application. In order to search for a safe and environmentally friendly reagent that can promote litchi pollination and fertilization in production, the present invention sprays litchi at the flowering stage Nano-titanium dioxide solution, or the preparation of pollination solution containing nano-titanium dioxide for artificial pollination can improve the natural pollination and fertilization of litchi flowering period or artificial pollination, thereby improving the pollination and fertilization ability of litchi flowering period, so as to reduce the risk of litchi flowering due to rainy low temperature or drought high temperature. The problem of poor pollination and fertilization; the application of nano-titanium dioxide in the flowering period of litchi can not only effectively prolong the flowering time of litchi and the meeting time of male and female flowers, but also improve the pollen germination rate, pollen vigor and stigma receptivity, promote pollination and fertilization of litchi flowering, and enhance the flowering time of litchi. The ability to resist low temperature rain or high temperature drought can increase the fruit setting rate, and can reduce the rate of spraying loss, which is safe and non-toxic.

Description

Technical field

[0001] The present invention belongs to the field of plant cultivation techniques, and in particular, the present invention relates to compounds which increase the ability of litchi period and its application.Background technique

[0002] Litchi Chinensis Sonn. The famous subtropical evergreen fruit trees in Sapindaceae, originated from China, known as fruit shaped, color, fragrance, taste and nutritious and nutritious For the "Lingnan Fruit King", "Human Fairy", "Buddha" and "Fruit King", etc., the reputation is well known. my country is the Litchira Country and the world's first production big country, mainly distributed in Guangdong, Guangxi, Fujian, Hainan and Taiwan and other places, 81% and 70% respectively from the world, respectively. In one of the rural industrial structure in the provinces of South China, Litchi is one of the pillar industries. Litchi is also one of the most active power of my country, exported to the potential of the exports.

Embodiment 1

[0030]Example 1 Study on the growth of lychee flower during the nano-titanium dioxide

[0031]Test method: A small amount of water is added to the ultrasonic power in the ultrasonic power of 500W, and the ultrasonic frequency is 500W, and the ultrasonic frequency is 10 min under the condition of 20 kHz, and then water is prepared into different concentrations of nano-titanium dioxide solution ( 0, 150, 300, 450, 600, 900mg / L), in the flower buds selection sunny morning to spray the lychee whole plant (focusing on spraying spikes), spraying to the dripping, the flowering period after spraying The flowering dynamics (each batch of flowers start, the length of the female flowers, the length of pollen germination, the length of the pollen tube, and the fruit rate.

[0032](1) Flowering dynamic observation

[0033]Taking the "scorpion laugh" and "Guihua" two lychee breeds as observations, in the first batch of female flowers / male flower buds in the morning, spraying 150 mg / l and 450 mg / l ...

Embodiment 2

[0048]Example 2 Nano-titanium dioxide improved the artificial pollination effect of lychee

[0049]Test method: Litchi often pollination in the rainfall flowers, requires artificial assistance to verifying the effect of nano-titanium dioxide on artificial pollination in lychee, including different concentrations of nano titanium dioxide (0,150,300,450,600mg / L) Pollination liquid (pollen: nano titanium dioxide: water = 1 g: 0.15 g: 5kg) is artificially pollubby, two days before pollination, the pistil column has been extended and the open flower spike, using 28 × 36 cm sized wood pulp paper waterproof bag will The whole flower spike is set, do not hurt the flowers and leaves, and listed. During the kit, it is slightly more than 120 ° -180 °, and the stretched angle of 120 ° -180 ° is slightly more artificially polished. Spraying in the female flowers, after spraying, the pistant column is performed during each batch of spending hours to Xiehua period.
