Wild effective harvesting method of phyllospadix iwatensis fruit

Abstract

The invention relates to a wild effective harvesting method of a phyllospadix iwatensis fruit. The method includes the steps: collecting female spathes of fruits with the length of 2mm and the width of 3.5mm in an effective pollination radius ring (20m) of female flowers on the peripheries of male plant patches based on accurate positioning of the male plant patches in population at a full-bloom stage; placing the female spathes into a 40-mesh net bag; locally hanging the net bag in sea water for 15 days; taking out the net bag after the female spathes completely mature. Under the conditions of light, temperature and the like in a natural sea area, the male plants are positioned, and a fruit picking water area and fruit picking size are limited, so that high harvesting rate of the phyllospadix iwatensis fruit is achieved under the conditions of low cost and labor intensity.

Description

technical field [0001] The invention belongs to the field of seaweed fruit harvesting, and relates to a method for harvesting red fiber shrimp seaweed fruit in the field. Background technique [0002] Red fiber shrimp seaweed (Phyllospadix iwatensis) is a marine seed plant belonging to Zosteraceae and Phyllospadix. Dominant species. Compared with Zostera marina, its leaves are narrower and have higher fiber content, so its leaves are the preferred seaweed leaves in the construction of the "seaweed house" of Jiaodong's traditional characteristic houses. However, due to coastal eutrophication and other reasons, its population has declined sharply in the coastal areas of China in the past two decades. Therefore, there is an urgent need to conduct conservation and restoration research on its population. [0003] The red fiber shrimp seaweed in Shandong, Hebei and Liaoning waters generally enters the flowering period in April, and enters the fruit ripening period in May-June. ...

AI Technical Summary

Problems solved by technology

Therefore, although it is easy to collect spathe, the efficiency of fruit collection is greatly reduced due to the low rate of fruiting. This is an important reason why there are very few related studies on the germination and physiology of red fiber shrimp seaweed fruit (seeds)
