Description

Mature zostera marina seed sorting unit

Technical Field

The utility model relates to a ripe big leaf algae seed selects separately technical field, in particular to ripe big leaf algae seed sorting unit.

Background

Zostera marina (Zostera marina L.) is an important sea grass in the northern sea area of China, and is distributed from Liaoning to Shandong along the coast. The zostera marina has flourishing leaves and developed underground roots, can weaken the bank impact force of tide, stabilize coastal sediments and provide food for numerous marine organisms, and plays an important role in a marine ecosystem. The zostera marina produces up to 30000 grains/m per reproductive year through sexual reproduction²The seeds of (1) play an important role in the process of maintaining the existing and developing new zostera marina populations.

The relationship between the maturity and the vitality of the seeds is very large, and the thousand seed weight, the germination rate, the survival rate of seedlings and the like of the seeds are obviously influenced. As the zostera marina seeds are matured in batches from the lower parts of flowering branches, if the seeds are harvested too early, the maturity of the seeds is insufficient, the storage resistance of the seeds is reduced, the germination capacity of the seeds is weakened, the viability of the seedlings formed after germination is also reduced, and the like; if the harvest is too late, a large amount of mature seeds fall off and can not be collected along with the drift of ocean current, so that the seed source is greatly lost.

However, the methods for collecting zostera marina seeds known at present are mainly to use a dip net for fishing or direct manual collection in the maturation season of zostera marina seeds. Although the maturity of the zostera marina seeds collected by the above-mentioned zostera marina seed collection method is still good, there are some problems at the same time. Firstly, the original ecological grassland is greatly damaged, and when the seeds are fished by using a handsheet, parts of leaves growing with reproductive branches and vegetative branches of immature seeds are inevitably damaged, so that the original ecological grassland is greatly damaged; secondly, the operation time is short, the zostera marina seeds fall off immediately after being mature, so that the seeds are collected when the zostera marina seeds are mature, the operation time is short, and the requirement for large-scale seed collection cannot be met; thirdly, the collection efficiency is low, when the zostera marina seeds are mature, the plant coverage of the grassland is very high, great inconvenience is brought to the operation of a manual dip net, the zostera marina seeds are small, and manual collection is very time-consuming.
