Embodiment 1

[0015] The influence of embodiment 1 low temperature treatment on the rate of rosette

[0016] The eustoma seeds were treated in three ways: only refrigerated treatment (35 days at a low temperature of 10°C), refrigerated treatment (35 days at a low temperature of 10°C), and then dried (ventilated at 25°C until the water content of the seeds reached 8%) , no treatment (seeds placed at normal temperature); above-mentioned seeds were in a dark environment during treatment, and the humidity was 100%. Each treatment had 100 seeds, and 3 replicates were sown on June 15 in a facility capable of irrigation and temperature regulation.

[0017] Sowing is carried out on a 200-hole hole tray with a vacuum seeder, and water is sprinkled every day after sowing to keep the hole tray moist until germination. After 4 to 6 true leaves, transplant to the cut flower cultivation area, and adopt conventional technical means for management and maintenance. Investigate flowering date, rosette rate...

Embodiment 2

[0022] The influence of embodiment 2 seed treatment mode on germination rate

[0023] The eustoma seeds were treated in three ways: only refrigerated treatment (35 days at a low temperature of 10°C), refrigerated treatment (35 days at a low temperature of 10°C), and then dried (ventilated at 25°C until the water content of the seeds reached 8%) , Preserve under 180d normal temperature (22 ℃); Above-mentioned seed is in dark environment during processing, and humidity is 100%, sowing on June 13, sowing adopts vacuum type seeder to sow on 200 hole trays, sprinkles water every day after sowing, Keep the plugs moist until germination occurs. After 4 to 6 true leaves, transplant to the cut flower cultivation area, and adopt conventional technical means for management and maintenance. Investigate the germination date, rosette rate, germination rate and other indicators. The impact of table 2 seed treatment on germination rate

Embodiment 3

[0027] The influence of embodiment 3 different low temperature values ​​and treatment time on the rate of rosette

[0028] The eustoma seeds were tested in terms of low temperature and treatment time: the low temperature value was treated with 5 temperature gradients of 5°C, 10°C, 15°C, 20°C, and 25°C, and the treatment time was 30d, 60d, 90d, 120d, 180d, the above seeds were treated in a dark environment with a humidity of 100%, and were sown in the facility on June 5. Sowing is carried out on a 200-hole hole tray with a vacuum seeder, and water is sprinkled every day after sowing to keep the hole tray moist until germination. After 4 to 6 true leaves, transplant to the cut flower cultivation area, and adopt conventional technical means for management and maintenance. Investigate the rosette rate, see Table 3.

Abstract

The invention discloses a cultivation method of eustoma grandiflorum (Raf.)Shinners. The cultivation method comprises the step of seed treatment, wherein seeds of eustoma grandiflorum (Raf.)Shinners are put in a dark environment of 0-20 DEG C for a certain period. According to the cultivation method, the seeds of eustoma grandiflorum (Raf.)Shinners are put under certain conditions like low temperature, darkness and a high moisture state to be treated, the occurrence of poor germination and the phenomenon of rosette-like growth after seeding of eustoma grandiflorum (Raf.)Shinners is completed can be avoided, large-area facilities or instruments are not needed, the treated seeds can be stored, sowing is easier, small granules are easy to treat, mechanical sowing becomes possible, the hierarchical workload is also lowered, and harvesting within a planned period also becomes possible. After the treated seeds are sowed, the phenomenon of the rosette-like growth hardly occurs, the germination rate is further increased, and the blooming quality is also improved.

Description

technical field [0001] The invention relates to plant cultivation, in particular to a method for preventing eustoma rosettes. Background technique [0002] Eustoma grandiflorum (Raf.) Shinners is a perennial plant of Gentianaceae, with a plant height of 30-100cm. The leaves are opposite, broadly elliptic to lanceolate, almost sessile, the base of the leaves is slightly clasped, and the surface of the leaves is blue-green. The stamens are obvious, the bracts are narrow and lanceolate, and the petals are imbricate. The flower color is rich, there are single color and double color, and the petals are divided into single petals and double petals. [0003] Eustoma, also known as prairie gentian, is native to the limestone zone between the southern United States and Mexico. Modern eustoma cultivation flourished in Japan. Commercial cultivation has begun in the 1960s. Lisianthus eustoma is one of the most popular types of potted and cut flowers in the world, with elegant and li...
