A kind of field effective harvesting method of red fiber shrimp seaweed fruit

Abstract

The invention relates to a method for effectively harvesting red fiber shrimp seaweed fruit in the field. On the basis of accurately locating the position of the male plant patch in the population at the full flowering stage, within the effective pollination radius circle (20m) of the female flower around the male plant patch Collect female spathes with a fruit size of >2mm in length and >3.5mm in width, place them in a 40-mesh net bag, hang them in seawater for 15 days, and retrieve them after they are fully mature. Under the conditions of light and temperature in natural sea areas, the present invention utilizes male plants to locate and limit the water area and the size of fruit picking, thereby achieving a high harvest rate of red fiber shrimp seaweed fruit under the conditions of low cost and low 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)
