Embodiment 1

[0030] Step 11: Prepare spermine aqueous solutions with different concentrations.

[0031] Spermine (chemical name: OS-dimethylaminophosphorothioate, molecular formula: (CH3O)2SPNH2) was added to water to prepare a concentration of 10 -5 mol / l, 10 -4 mol / l, 10 -3 mol / l, 10 -2 mol / l or 10 -1 mol / l aqueous solution, stir well at room temperature. Further, in order to facilitate the attachment of the spermine aqueous solution to the surface of the attached flower leaves so as not to slip off, when using the above spermine aqueous solution, add Tween 20 (chemical name: polyoxyethylene sorbitan monolaurate, molecular formula: C58H114O26) by The concentration ratio (0.1-0.15%) is mixed and prepared.

[0032] Step 12: Spray the mango flower with an aqueous spermine solution within 10 days from the final flowering stage to fruit bearing.

[0033] Choose fruit-bearing trees of the same variety, such as Tainong No. 1 or Jinhuang Mango to form group A, each group has at least 3 pla...

Embodiment 2

[0037] Step 21: Prepare different concentrations of sodium nitroprusside (Na2Fe(CN)5NO.2H2O) aqueous solutions.

[0038] Add sodium nitroprusside into water to prepare an aqueous solution with a concentration of 0.10mol / l, 0.05mol / l or 0.01mol / l, and stir evenly at room temperature; when in use, add Tween 20, the concentration of Tween 20 varies with plants Different, it can make the aqueous solution paste and attach to the surface of the flower leaves so as not to slip off.

[0039] Step 22: Spray the mango flowers with sodium nitroprusside solution within 10 days from the final flowering stage to fruit bearing.

[0040]Select fruit-bearing trees of the same variety, such as Tainong No. 1 or Jinhuang Mango, to form Group B, with at least one plant in each group. Select 5 to 10 inflorescences with consistent flowering in the middle and upper parts of each tree body, mark them, and record each The number of inflorescence flowers per treatment.

[0041] At the end of the flowe...

Embodiment 3

[0044] Step 31: Prepare an aqueous solution of urea, boric acid, sodium molybdate and magnesium sulfate.

[0045] Add urea, boric acid, sodium molybdate and magnesium sulfate into water, the concentration of urea in the solution is 0.2% mol / l, the concentration of boric acid is 0.1% mol / l, the concentration of sodium molybdate is 0.30% mol / l, sulfuric acid The concentration of magnesium is 0.10% mol / l. Calcium chloride can also be added, and the concentration of calcium chloride in the solution can be 0.1% mol / l, 0.3% mol / l or 0.5% mol / l, and the solution is stirred evenly at normal temperature. When in use, the above-mentioned aqueous solution varies from plant to plant, and adding Tween 20 can make the aqueous solution paste and adhere to the surface of the flower leaves so as not to slip off.

[0046] Step 32: Spray the mango flowers with an aqueous solution of urea, boric acid, sodium molybdate and magnesium sulfate within 10 days from the final flowering stage to fruit b...

Abstract

The invention discloses a method for improving the mango fruit setting rate, which comprises: preparing a fruit setting solution; and spraying the mango flower with the fruit setting solution during the flowering period and the fruit setting period. The fruit-setting solution is selected from spermine aqueous solution or sodium nitroprusside aqueous solution, or from urea, boric acid, sodium molybdate and magnesium sulfate aqueous solutions. The invention can improve the mango fruit setting rate and the proportion of large fruits, and reduce seedless fruits.

Description

technical field [0001] The invention relates to a mango cultivation technology, in particular to a method for increasing the mango fruit setting rate. Background technique [0002] Mango is one of the world famous tropical fruits. Among the tropical crops in my country, mango has played an important role in the development of production, and has achieved more significant economic and social benefits. However, the output per unit area in my country is only 499 kg / mu. Therefore, increasing the yield per unit area of ​​mango has become an urgent issue in the development of mango industry. The mango inflorescence is a panicle born on the top of the branch, with 5 petals, calyx and stamens, usually 1 stamen, and the rest degenerate. The flowers have male flowers, bisexual flowers and female flowers, which are born in the same inflorescence. The proportion of hermaphrodite flowers is generally 5-50%, but there are also less than 0.5%. The suitable temperature for mango pollin...
