An effective method for improving the quality of Ranunculus hybrid seeds

Abstract

The invention provides an effective method for improving the quality of ranunculus hybrid seeds, which specifically includes the following steps: (1) planting of parent materials: soaking seeds in warm water, placing them in a refrigerator at 0-4°C for 5-7 days, and accelerating germination at room temperature for 7-7 days 10 days, sow in non-woven nutrient bags, and the parents are planted according to 1:1-1.2 moisture separation, and 1200 plants are planted per mu; (2) Ground cover: full-covered with black polyethylene film with a light transmittance of less than 10%; (3 ) Greenhouse warming: control the temperature in the greenhouse to 15-20°C; (4) Supplementary light for male parents: use LED light strips for 24h supplementary light every day, and the light intensity is 2000-3000Lx; (5) Cross-pollination: after emasculation Start pollination in 3 days, and pollinate 3 times; (6) harvest seeds. The present invention greatly improves the pollen yield and pollen vigor of the ranunculus male plant through methods such as seed soaking, full film-covering cultivation, and male parent light supplementation, combined with reasonable temperature control, and further significantly improves the hybrid seed setting rate of ranunculus, the highest possible up to 94.5%.

Description

technical field [0001] The invention relates to the technical field of flower cultivation, in particular to an effective method for improving the quality of ranunculus hybrid seeds. Background technique [0002] Ranunculus, also known as celery flower and lulian flower, is a perennial herbaceous flower of the family Ranunculaceae and the genus Ranunculus. The flowers are rich in color, mostly double or semi-double. The flower shape is similar to peony flowers, but smaller. The flower diameter is generally 8-10cm. The leaves are like celery leaves, so they are often called celery flowers. Native to southeastern Europe and southwestern Asia. Introduced by the British for artificial cultivation in 1596, it is very common in gardens and cut flowers. It is cultivated in various countries, such as Holland, Britain, France, the United States, Japan, etc., and many cut flowers and potted varieties have been cultivated. China began to introduce from the Netherlands and Japan in th...

Problems solved by technology

[0004] Ranunculus hybrid seed production is mainly in winter and spring. Due to the low temperature, some varieties that are sensitive to low temperature have less pollen in the male parent, and the seed setting rate after hybridization is low, and the seed hollow rate is high, which can reach more than 70%, which is difficult to meet.
