Problems solved by technology

[0004] At present, the more excellent varieties of okra include Qingfu, Wufu and Nanyang. The sexual hybridization technology of okra is generally to remove the anthers from the stamen tube in the morning before the female parent flower of okra blooms, and then remove the corolla of the fully open autumn okra. The male sunflower flowers are tightly adhered to the stigma of the female parent and then sealed. The quality of the hybridization is closely related to manual operation, which is time-consuming and labor-intensive.

Embodiment 1

[0022] At 7 o'clock, collect flower buds from the male parent flower of Qingfu okra variety, remove the corolla, spread it flat on sulfuric acid paper, place it in a cool, dry and ventilated place, collect it after the pollen is scattered, and remove impurities with a 75 micron sieve. The pure pollen is obtained, and the pure pollen is placed in a light-proof bottle and sealed, and stored at a low temperature and protected from light until use. Put pollen, indole butyric acid, white granulated sugar, boric acid and gum arabic into water respectively, ultrasonicate for 25 minutes, and stir evenly to obtain a pollen suspension for use. The concentration of pollen in the pollen suspension is 3g / L, and indole butyric acid 2g / L for white sugar, 2g / L for boric acid, and 1g / L for gum arabic.

[0023] 2 days before the okra female parent flower blooms, the stigma part is isolated by bagging, and at 8 o'clock on the first day of flowering, the isolate is removed, and the pollen suspens...

Embodiment 2

[0025] At 10 o'clock, collect flower buds from the male parent flower of Wufu okra variety, remove the corolla, spread it flat on sulfuric acid paper, place it in a cool, dry and ventilated place, collect it after the pollen is scattered, and use a 100-micron sieve to remove impurities. The pure pollen is obtained, and the pure pollen is placed in a light-proof bottle and sealed, and stored at a low temperature and protected from light until use. Put the pollen, indole butyric acid, white granulated sugar, boric acid and gum arabic into water respectively, ultrasonicate for 30 minutes, and stir evenly to obtain a pollen suspension for use. The concentration of pollen in the pollen suspension is 3g / L, and indole butyric acid 2g / L for white sugar, 2g / L for boric acid, and 1g / L for gum arabic.

[0026] The stigma part is isolated by bagging 3 days before the flowering of the okra female parent flower, and at 15 o'clock on the first day of flowering, the isolater is removed, and t...

Embodiment 3

[0028] At 8 o'clock, collect flower buds from the male parent flower of the Nanyang okra variety, remove the corolla, spread it flat on sulfuric acid paper, place it in a cool, dry and ventilated place, collect it after the pollen is scattered, and remove impurities with an 80-micron sieve. The pure pollen is obtained, and the pure pollen is placed in a light-proof bottle and sealed, and stored at a low temperature and protected from light until use. Put the pollen, indole butyric acid, white granulated sugar, boric acid and gum arabic into water respectively, ultrasonicate for 30 minutes, and stir evenly to obtain a pollen suspension for use. The concentration of pollen in the pollen suspension is 3g / L, and indole butyric acid 2g / L for white sugar, 2g / L for boric acid, and 1g / L for gum arabic.

[0029] The stigma part is isolated by bagging 2 days before the flowering of the female parent flower of okra, and at 9 o'clock on the first day of flowering, the isolater is removed,...

Abstract

The invention discloses an effective sexual hybridization technology of abelmoschus esculentus. The effective sexual hybridization technology is characterized in that the mechanical spray technology is performed for pollination of abelmoschus esculentus so as to achieve effective sexual hybridization. The effective sexual hybridization technology specifically comprises the steps of removing corolla of flower bud of paternal flower of abelmoschus esculentus and drying in the shade to obtain powder; filtering and purifying to obtain pure powder; preparing suspension liquid through the pure powder; spraying the suspension liquid to maternal flower which is isolated before flowering; spraying and pollinating again after two to three days; cutting off non-pollinated capsules; then performing normal field management. With the adoption of the effective sexual hybridization technology of abelmoschus esculentus, the influence of weather and other natural factors on the pollination effect can be weakened; the manpower and cost are less than those in manual dropping for pollination, therefore, the efficiency is improved, and the output as well as the economic benefit of abelmoschus esculentus can be increased.

Description

Technical field: [0001] The invention belongs to the technical field of vegetable planting, in particular to a high-efficiency sexual hybridization technology of okra. Background technique: [0002] Okra (Abelmoschus esculentus L. Moench), also known as okra, coffee ambrette, croissant, kidney tonifying grass, pearl vegetable, etc., is an annual herb of the genus okra in the Malvaceae family. Okra is a vegetable, medicine and flower dual-purpose plant. It is not only delicious, but also has obvious medicinal effects. Its flowers, seeds and roots can be used as medicine. It contains various vitamins, minerals, zinc, selenium and other trace elements. It is also rich in pectin, bovine lactan and arabinan, which can enhance the body's immunity, have an auxiliary therapeutic effect on constipation, gastric ulcer, hemorrhoids and diabetes, and can also resist fatigue and improve vitality. [0003] The plant of okra is similar to cotton, with a well-developed root system, upright...
