Cold area wet land gorgon fruit seed germinating and efficient seedling planting method

Abstract

The invention discloses a cold area wet land gorgon fruit seed germinating and efficient seedling planting method and belongs to the field of cultivation and production of wetland plants. The method aims at solving the problems that in a cold area, gorgon fruit seeds are low in germination rate, low in germination speed, low in seedling survival rate and difficult to plant. The planting method comprises the steps that 1, seeds are selected and stored; 2, after the seeds are disinfecte,d a GA3 solution is sprayed, and the seeds are refrigerated for 5-7 days at the temperature of 2 DEG C to 4 DEG C; 3, cultivation is carried out through the alternate modes of waterflooding, non-waterflooding and re-waterflooding until the seeds germinate; 4, gorgon fruit seedlings are transplanted into a natural wetland; 5, seedling management is carried out. According to the method, the seeds are stored under the waterflooding condition in the natural environment, the vigor of the seeds can be kept, physical hull breaking, chemical germination accelerating, dry-wet alternate environment changing and other methods are combined, seed dormancy is fast broken through, and the germination rate is obviously increased and reaches 92.3%; the seedlings are cultivated in a shallow water environment, seedling growth is benefited, then directional transplanting is carried out, and the survival rate of the seedling is increased.

Description

technical field [0001] The invention belongs to the field of cultivation and production of wetland plants, and in particular relates to a method for germination of gorgon seeds and high-efficiency planting of seedlings in cold regions. Background technique [0002] Gorgon, also known as chicken head rice, chicken head lotus, thorn lotus, is an annual aquatic herb of Nymphaeaceae, with white fibrous roots and inconspicuous stems. The primary leaves are submerged leaves, arrow-shaped or oval kidney-shaped, with gaps; Secondary leaves are floating leaves, leathery, oval reniform to round, petiole is long, cylindrical, hollow and spiny, leaf surface is mostly raised, and air sacs are collected under it; flowers are solitary on the top of pedicels, sepals are lanceolate Shaped, most of the petals are purple, the seeds are spherical, the flowering period is July-August, and the fruiting period is August-September. Gorgon is an aquatic plant with both medicine and food. [0003] ...
