Substrate specially used for sowing seeds and raising seedlings of Hibiscus hamabo

Abstract

The invention mainly relates to the technical field of planting and discloses a substrate specially used for sowing seeds and raising seedlings of Hibiscus hamabo. The substrate is made from: corncob,edible mushroom culture medium, seed case of Hibiscus syriacus, cotton seedlings, peanut shell, chili seedlings, chicken manure, pine needles, fructus xanthii, plant ash, vermiculite, perlite, ceramsite and lactic acid bacteria. The substrate includes abundant raw materials and has balanced nutrients, is rich in inorganic and organic nutrients, is easy to absorb and convert in the Hibiscus hamabo, can accelerate growth of radicle and germ and increase germination rate of seeds to 37.4%. In the invention, the corncob, edible mushroom culture medium, seed case of Hibiscus syriacus, cotton seedlings, peanut shell and chili seedlings are crushed and then are subjected to short-time fermentation via the lactic acid bacteria; wherein pH value is reduced to accelerate softening of the seed caseand further generate large amount of small-molecular nutrients, which are easy to absorb by seeds, so that the substrate can promote germination of seeds, reduce germination time of seeds and increasegermination rate of the seeds.

Description

technical field [0001] The invention mainly relates to the field of planting technology, in particular to a special substrate for sowing and raising seaside hibiscus seedlings. Background technique [0002] Seaside hibiscus generally grows in seaside saline-alkali land, with golden color and bright and beautiful flowers. It is an excellent garden greening seedling, and it is also a good windbreak and sand-fixing, embankment and moisture-proof seedling. It can be used as coastal protection forest. However, the seed shell is hard and the germination rate is low. The document "The Effect of Seed Soaking at Different Temperatures on the Germination Rate of Seaside Hibiscus Seeds, Xu Senfu, etc." discloses soaking in hot water at 60-90°C and then soaking in cold water for 48 hours, and then putting them into culture After 40 days, the seed germination rates were 21.67%, 28.33%, 23.33%, and 26.67%, respectively. In this ideal state, the germination rate of seaside hibiscus is extr...

[0002] Seaside hibiscus generally grows in seaside saline-alkali land, with golden color and bright and beautiful flowers. It is an excellent garden greening seedling, and it is also a good windbreak and sand-fixing, embankment and moisture-proof seedling. It can be used as coastal protection forest. However, the seed shell is hard and the germination rate is low. The document "The Effect of Seed Soaking at Different Temperatures on the Germination Rate of Seaside Hibiscus Seeds, Xu Senfu, etc." discloses soaking in hot water at 60-90°C and then soaking in cold water for 48 hours, and then putting them into culture After 40 days, the seed germination rates were 21.67%, 28.33%, 23.33%, and 26.67%, respectively. In this ideal state, the germination rate of seaside hibiscus is extremely low, which obviously reduces the sowing and reproduction efficiency of seaside hibiscus. Seedlings can improve the environmental and nutritional conditions in seaside hibiscus, but there are very few substrates specially used for seaside hibiscus seedlings on the market
