Method for promoting morning glory to bloom and seed

Abstract

The invention discloses a method for promoting morning glory to bloom and seed. The method comprises the following steps of soaking and disinfecting well-chosen morning glory seeds with potassium permanganate solution, repeatedly washing and cleaning the well-chosen morning glory seeds with clean water, draining off water, and scraping testas at raphes of the disinfected morning glory seeds broken to enable radials to break through the testas with a blade to be reversed, sowing preprocessed morning glory seeds into a hole disk to grow seedlings, covering morning glory seedlings with a cover frame with shading cloth when each morning glory seedling grows out 4 main leaves, shading the morning glory seedlings and controlling temperature of the morning glory seedling for 7-15 days, controlling temperature of a seedbed between 18 DEG C to 28 DEG C in processing, enabling illumination time of each day to be 8 to 10 hours, and planting the shading-treatment seedlings into seed farm until the seedlings bloom and seed. The method is simple and practical, low in cost, capable of promoting morning glory to bloom and seed in advance, capable of achieving the purpose of cultivating various morning glories in local area, high in yield and suitable for seed production in large area.

Description

technical field [0001] The invention relates to a method for promoting flowering and fruiting of plants, in particular to a method for promoting flowering and fruiting of morning glory, and belongs to the technical field of plant cultivation. Background technique [0002] Morning glory belongs to Convolvulaceae, Petunia genus, annual twining herb, native to tropical Asia, widely introduced and planted all over the world, most popular in Japan, with the most artificially cultivated fine varieties, distributed in most parts of my country. Morning glory has strong adaptability, fast growth, luxuriant flowers and leaves, strong covering power, heat resistance, drought resistance, poor soil resistance, sun-loving and shade-tolerant, and extensive management. It is the best choice for landscaping, artificial landscape and home courtyard beautification Good material, the ornamental effect is very good, the demand is increasing year by year. At present, there are many varieties of...

AI Technical Summary

Problems solved by technology

At present, there are many varieties of morning glory for cultivation and ornamental use, but some morning glory varieties, such as large-flowered morning glory and split-petal morning glory, have strong ornamental flower shapes and colors, but there are problems in seed production , these varieties of morning glory are more sensitive to the light time, seedlings are sown in mid-February, spring sowing flowering time is from the end of May to early June, when the flowering period happens to be high temperature and high humidity weather, most of the morning glory will not bear fruit after flowering If you sow seedlings in late June, the time for autumn sowing to bloom is generally at the end of September or early October. Although you can bloom and watch them at this time, for seed production, most of the seeds that bloom and bear fruit during this period are not yet mature, and frost will cause them to bloom. Coming, the yield is very low. In order to harvest the seeds, it is often necessary to go to Hainan to multiply the seeds, and the production cost and transportation cost are greatly increased.
