Problems solved by technology

Among the three types of formulations, 2,4-D, the pure plant growth regulator formulation, has better effect, but its side effects are also relatively large, and it is easy to produce deformed fruit. Improper use of concentration will inhibit fruit growth, and even cause fruit drop, which is relatively safe. Poor, after several years of continuous use, it will also cause poor plant growth; pure nutritional preparations have limited fruit preservation effects due to the lack of anti-stress hormones and plant growth regulators that inhibit the activity of pectin methylesterase and pectinase

Embodiment 1

[0033] Weigh the following substances: 200 mg of amino acids, 90 mg of calcium acetate, 25 mg of borax, 20 mg of fulvic acid, 18 mg of chlorophenoxyacetic acid, 15 mg of gibberellic acid, 5 mg of forchlorfenuron, and 50 mg of 0.1% brassinolide. First add chlorophenoxyacetic acid, gibberellic acid, and forchlorfenuron to 30ml of hot ethanol (50°C), stir to dissolve with a glass rod, and mix with amino acids, calcium acetate, borax, fulvic acid, 0.1% brassin The esters are dissolved together in 1 liter of distilled water or deionized water, and stirred and mixed to obtain Feizixiao litchi fruit preservation agent solution.

[0034] Start spraying 10 days after Feizixiao litchi tree has faded, and spray once every 8 days for a total of 3 sprays. When spraying, focus on the fruit ears and spray until dripping water. Before spraying and when the fruit is ripe, investigate, measure the number of fruits and the weight of each fruit, and calculate the relative fruit setting rate (number ...

Embodiment 2

[0036] Weigh the following substances: 180 mg of amino acids, 80 mg of calcium acetate, 20 mg of borax, 15 mg of fulvic acid, 10 mg of chlorophenoxyacetic acid, 10 mg of gibberellic acid, 4 mg of forchlorfenuron, and 25 mg of 0.1% brassinolide. First add chlorophenoxyacetic acid, gibberellic acid, and forchlorfenuron to 30ml of hot ethanol (50°C), stir to dissolve with a glass rod, and mix with amino acids, calcium acetate, borax, fulvic acid, 0.1% brassin The esters are dissolved together in 1 liter of distilled water or deionized water, and stirred and mixed to obtain Feizixiao litchi fruit preservation agent solution.

[0037] Start spraying 10 days after Feizixiao litchi tree has faded, and spray once every 8 days for a total of 3 sprays. When spraying, focus on the fruit ears and spray until dripping water. Before spraying and when the fruit is ripe, investigate, measure the number of fruits and the weight of each fruit, and calculate the relative fruit setting rate (number ...

Embodiment 3

[0039] Weigh the following substances: 120 mg of amino acids, 80 mg of calcium acetate, 15 mg of borax, 10 mg of fulvic acid, 10 mg of chlorophenoxyacetic acid, 10 mg of gibberellic acid, 4 mg of forchlorfenuron, and 20 mg of 0.1% brassinolide. First add chlorophenoxyacetic acid, gibberellic acid, forchlorfenuron, and brassinolide to 30ml of hot ethanol (50°C), and stir to dissolve with a glass rod, and then mix with amino acids, calcium acetate, borax, fulvic acid, 0.1% brassinolide is dissolved in 1 liter of distilled water or deionized water, and stirred and mixed to obtain Feizixiao lychee fruit preservation agent solution.

[0040] Start spraying 10 days after Feizixiao litchi tree has faded, and spray once every 7 days for a total of 3 sprays. When spraying, focus on the fruit ears and spray until dripping. Before spraying and when the fruit is ripe, investigate, measure the number of fruits and the weight of each fruit, and calculate the relative fruit setting rate (number...

Abstract

The invention discloses a fruit retention agent as well as a preparation method and a use method of Feizixiao litchis. The fruit retention agent is prepared from amino acid, calcium acetate, borax, fulvic acid, p-chlorophenoxyacetic acid, gibberellin, forchlorfenuron and brassinolide. The fruit retention agent for the Feizixiao litchis is applied to the fruit retention of the Feizixiao litchis ten days after blossom falls in the mode of cluster spraying. The relative fertile fruit percentage of the fruit retention agent is 8.37 percent, which is improved by 37.70 percent compared with that of a contrast, and the weight of single fruit is not influenced. The fruit retention agent has low cost, simple preparation and simple and convenient operation and is easy of large-scale popularization. The fruit retention agent for the Feizixiao litchis is also suitable for the fruit retention of other varieties of litchis.

Description

Technical field [0001] The invention relates to a fruit preservation technology for fruit trees, in particular to a fruit preservation technology for Feizixiao litchi. Background technique [0002] Litchi (Litchi chinensis Sonn.) is native to my country, and its cultivation area and output account for about 80% and 65% of the world's total. It is the world's largest litchi producer. my country has more than 2,000 years of litchi cultivation history, has accumulated rich cultivation experience, and has also cultivated many excellent varieties that adapt to different ecological environments. [0003] Feizixiao is an early-middle-maturing lychee variety cultivated in my country that is resistant to storage and transportation and has good quality. It is also the most exported variety in my country. Compared with other varieties, Feizixiao litchi can also undergo flower bud differentiation at a higher temperature, and it is easier to form flowers, so it has become the main plant variet...
