Out-of-season breeding method in gladiolus seedball sunlight greenhouse

Abstract

The invention discloses an out-of-season breeding method in a gladiolus seedball sunlight greenhouse. The sowing time is from last ten days of August to first ten days of September; sowing is carried out when the highest outdoor temperature is lower than 29 DEG C, and the sowing time is postponed for 4-5 months compared with a normal sowing period; from the end of April to the end of May in the second year, when a seedball grows for 8-9 months, the average circumference of the seedball is above 12cm; through a manner of controlling water, a plant is forced to hibernate; when the part of the plant on the ground withers, the seedball is dug; the gladiolus seedball is soaked by 800 times of 40% of methanal or by 0.3% of potassium permanganate, and is dried in the air and placed in a refrigeration house with 2-4 DEG C to be stored for 3 months; and seedballs processed at low temperature and used for production are taken out from the refrigeration house to be planted in batch according to time to market. The out-of-season breeding method in the gladiolus seedball sunlight greenhouse has the advantages of postponing sowing and harvesting periods, reducing the storage time of the seedballs, saving the storage cost, reducing nutrition consumption of the seedballs, and improving the seedball quality.

Description

technical field [0001] The invention relates to a technique for breeding gladiolus bulbs, in particular to a method for off-season breeding of gladiolus bulbs in a solar greenhouse. Background technique [0002] Conventional gladiolus bulb breeding method: sow seeds in March-April every year, plant in the open field, adopt conventional daily management, and harvest bulbs in October-November of the year. Its shortcoming is: 1, storage time is long. Sow seeds in March-April, and harvest bulbs in October-November of that year. If it is used for the production of Xiaohua in the second year, the bulbs must be stored until August-September of the second year, and the storage period is nearly 1 year, which increases storage costs. 2. The quality of the bulbs is poor. The storage time is long, the nutrient consumption of the bulb is large, and the rot rate of the bulb reaches more than 20%. 3. The quality of the fresh flowers produced is poor. In the second year of off-season c...

Problems solved by technology

Its shortcoming is: 1, storage time is long

If it is used for the production of Xiaohua in the second year, the bulbs must be stored until August-September of the second year, and the storage period is nearly one year, which increases storage costs

2. Poor quality bulbs

The storage time is long, the nutrient consumption of the bulb is large, and the rot rate of the bulb reaches more than 20%.

3. The quality of the flowers produced is poor

If imported bulbs are planted, although the flowering rate and quality are high, the price of the bulbs is high, the production cost is high, the profit is reduced, or even a loss
