Granule spray sowing method for breeding Noni on tropical reef

Abstract

The invention discloses a granule spray sowing method for breeding Noni on a tropical reef. The method comprises the steps of 1, rinsing mature seeds of the Noni to be clean, soaking the seeds with warm water, and drying the seeds in shade; treating the seeds with gibberellin; 3, adopting desalination seawater to leach sea sand or coral sand; preparing an artificial soil layer and a seed layer on a leaching layer through a granule spray sowing technology; 5, adopting a sunshade net to cover the seed layer; 6, when seedlings grow to 4-5 cm, removing the sunshade net. Comparing the granule spray sowing method for breeding Noni on the tropical reef with a common artificial planting greening method, the construction speed is high, the prepared artificial soil medium is good in quality, and the Noni has a better capacity in resisting wind and erosion of rain; the emergence rate of the Noni seeds is raised to 85% and above, and the emergence time is shortened by 15-20 days; through maintenance means of sun shading, water and a fertilizer after sowing, the growth of the seedlings is promoted, and the effect of quick scale breeding is achieved.

Description

technical field [0001] The invention belongs to the technical field of breeding and planting sisanoni fruit, in particular to a pellet spraying method for breeding sisanoni fruit on tropical islands and reefs. Background technique [0002] The harsh natural environment on tropical islands and reefs, high temperature, high humidity, high salinity, high alkalinity, and sea breeze seriously affect the reproduction and growth of plants. Most plants are difficult to adapt to the local climate, especially newly built tropical reclaimed islands and reefs. At present, sisanoni fruit is mainly propagated by planting on tropical islands and reefs. This method of breeding sissanoni fruit by planting sisanoni fruit consumes a lot of manpower and material resources; The skin is hard, germination is difficult, and the germination rate of direct sowing is very low. On the tropical reclamation islands and reefs, the sunlight is strong, the sown seeds and seedlings are easy to burn, and the...

Problems solved by technology

At present, sisanoni fruit is mainly propagated by planting on tropical islands and reefs. This method of breeding sissanoni fruit by planting sisanoni fruit consumes a lot of manpower and material resources; The skin is hard, germination is difficult, and the germination rate of direct sowing is very low

The sun rays are strong on the tropical reclamation islands and reefs, the sown seeds and seedlings are easy to burn, and the seed emergence rate and seedling survival rate are very low

There is a lack of materials on the newly built reclaimed islands and reefs, and it is difficult to provide the materials and equipment used in the common germination methods. Therefore, it is necessary to find a simple and effective germination method

In order to prevent seeds and seedlings from being burned, straw or plastic film is often used to cover the straw. The straw is difficult to resist the strong wind at sea and cannot maintain a long covering time; the plastic film is easy to cause secondary pollution and is not conducive to irrigation of the spraying area.
