Soilless seedling cutting raising method of gardenia jasminoides in potted trays of rice field

Abstract

The invention discloses a soilless seedling cutting raising method of gardenia jasminoides in potted trays of the rice field. The soilless seedling cutting raising method includes steps of (1) rice planting; (2) cutting spike selecting; (3) cutting spike treatment; (4) cutting; (5) cutting management. In the soilless seedling cutting raising method, cutting is performed by adopting the soilless potted trays in the rice field, air humidity in reserved rice row spaces is kept above 80%, leaves cannot wither by water loss, light transmittance rate is 10-30%, leaves can be kept as many as possible for photosynthesis, and nursery-grown plants with more than 20 roots can be grown in the same season by cutting in summer. By soilless matrix, diseases are seldom caused, the raised nursery-grown plants can be grown hydroponically and also can be transplanted to flower pots or the earth. Without establishing greenhouses and sunshading nets, spraying water for keeping moisture, and intertilling and weeding and the like, management is convenient and mass propagation can be realized. Gaps among ridge-bordered plots in the rice field are adopted for raising the plants, period is short and is about two months, rice yield is unaffected, land is saved, and massive propagation can be realized.

Description

technical field [0001] The invention relates to the technical field of nursery stock cultivation, in particular to a method for cultivating gardenia seedlings with plugs in paddy fields without soil. Background technique [0002] Gardenia (Gardenia jasminoides Ellis), an evergreen dwarf shrub of the Rubiaceae Gardenia genus, is an excellent landscaping tree species, and is also an important potted flower and cut flower. Seedlings. [0003] Gardenia propagation methods include seed propagation, branch propagation, layering propagation, tissue culture and cutting propagation. [0004] Seed propagation cannot maintain the excellent traits of the female parent, and layering and division are used for propagation, and the reproduction coefficient is low. Although tissue culture can reproduce in large quantities, it has a long cycle for seedling formation and relatively high technical requirements. [0005] The water cutting method takes root faster than the soil cutting method,...

However, hydroponic cuttings have not yet been used in large-scale production

[0006] In mid-July 2000 (Zhongxiu Lin), cut the hard branches of Gardenia jasminoides. The main trunk is 10-20cm long, and 5-6 branches are left, and inserted into the vigorously growing rice field. The depth is 5-8cm, and it can form large gardenia seedlings with 21 roots, but the number of cuttings is limited, and it is inconvenient to dig seedlings, which affects rice harvesting
