Seedling raising method for improving rapid seedling formation of Australian water lily seed seedlings

Abstract

The invention discloses a seedling raising method for improving rapid seedling formation of Australian water lily seed seedlings. The seedling raising method comprises the following steps: step 1, accelerating germination of seeds; step 2, carrying out sowing; step 3, setting transplanting time; and step 4, conducting maintenance after transplanting; wherein in the step 1, firstly, selected seeds are placed in a proper environment to be subjected to germination accelerating treatment; in the step 2, a garden soil matrix is selected, soil is loaded into a pot in advance, the soil mass accounts for 1 / 3 of the volume of the pot, the soil is soaked in clear water and stirred, impurities are removed, sowing is conducted after the water is clear, and the sowing temperature is preferably 25 DEG C or above; and in the step 3, after passing through the Qingming, the air temperature is stabilized at 25 DEG C or above, the temperature difference is smaller than 5 DEG C, and more than three floating leaves larger than 2 cm are needed for the seedling condition. According to the method disclosed by the invention, the water lily seeds are subjected to germination accelerating, sowing and transplanting treatment at the proper temperature and in the proper environment, so that the period of the water lily from the seeds to seedling and flowering is effectively shortened, and the cross breeding process of the water lily is accelerated.

Description

technical field [0001] The invention relates to the technical field of seedling breeding, in particular to a seedling raising method for improving the rapid seedling growth of Australian water lily seed seedlings. Background technique [0002] With the continuous improvement of domestic water lily breeding level, the demand for water lilies in the cut flower market is increasing, and people have higher and higher requirements for the ornamental quality of Australian water lilies. It is particularly necessary to improve the varieties of Australian water lilies through hybridization. However, Australian water lilies are native to the tropical regions of Australia. In subtropical regions, there are problems of seed germination, slow seedling growth and low efficiency, which greatly limits the breeding process of new Australian water lilies. [0003] In view of this, it is necessary to design a seedling raising method to improve the rapid growth of seedlings of Australian water ...
