1, environment of origin:
Eustoma grandiflorum is native to Colorado, Nebraska, Texas and New Mexico. Since 1970s, Eustoma grandiflorum, as a cut flower, has become popular in Japan and South Korea.
2. Growth habits:
Sex likes a warm, humid and sunny environment. Relatively drought-resistant, water-resistant and moisture-resistant. The optimum growth temperature is 15-28℃, and the night temperature should not be lower than 12℃. When the temperature is lower than 5℃ in winter, the leaves are rosette-shaped and cannot bloom. When the temperature exceeds 30℃, the flowering period is obviously shortened. It is strict with water and likes to be wet, but too much water is not good for root growth. If the water supply is insufficient, the stems and leaves will grow very thin and bloom early. Sensitive to light, long sunshine is helpful to stem and leaf growth and flower bud formation.
The pH value of loose, fertile and well-drained soil should be 6.5-7.0, and continuous cropping is prohibited. Eustoma grandiflorum needs to go through a period of low temperature, high temperature and natural flowering from May to July. Annual flowering can be realized under certain facilities and cultivation techniques.
3, breeding technology:
Foreign countries often sow and breed. The seeds are very small, generally about 654.38+00000 grains per gram, so the seeds of Euonymus grandiflora are often coated. The germination rate of coated seeds is higher. It is best to broadcast indoors in September-65438+10 or 1-2. The seeds are small, like light, and need not be covered with soil. The optimum temperature for germination is 22-25℃, and it germinates 12- 15 days after sowing. After half a month, the seedlings grow very slowly. It takes 120- 140 days from sowing to flowering, and 150- 180 days for cut flowers. In the seedling market, Eustoma grandiflorum also has a small number of tissue culture seedlings and cuttings.
