Update: 10/24/2014

10 years ago, some people in the village of Dong Ha, Ninh Hai ward, town of Ninh Hoa (Khanh Hoa) has brought grape varieties from Japan follower of local trials. Since then, this plant is constantly evolving in terms of both quantity and quality, to become export products to high income. For this model grows more recently mass union provincial agencies, in coordination with mass base Department of Agriculture and Rural development and technology transfer organizations grapes grown on the street for residents blisters methods. This technique yields and higher quality than the bottom of the planting method as before.

So far, grape growers seaweed wards in Ninh Hai, Ninh Hoa town mainly seaweed directly to the bottom of ponds. With this method, the tree was rooted to the ground, so when heavy rainfall or temperature changes, easy street trees die. Besides, this method is quite exhausting and time of harvesting and rehabilitation.

With seaweed on the blister method, most of the downside has been overcome. Rong grapes grown in blister has absorbed nutrients from the pond bottom, favorable harvest for each adapter can put ashore, when trouble can also quickly switch the grape wide to other ponds. Besides, this approach also yields more than doubled compared to the plant floor, from 65 to 70 tonnes / ha / year.

Dang Ngoc Thoai - grape growers seaweed wards Ninh Hai, Ninh Hoa TX before he shared no capital investment only 1 ha planted as bottom pickers 1 week about 2 tons. And now invested almost 2 months now pack a week is 3 tons, more than 1 ton for 1 week compared with previous methods.

Huynh Kim Khanh - The Director of the Aquaculture Department, said Khanh Hoa with blisters on planting methods farmers can maneuver. When the temperature is high, the pond bottom can raise blisters on higher floor, when heavy rain, low salinity, it can move through the different ponds to increase salinity to ensure the same. Therefore, the plant is more active blisters on the production as well as keeping the same through the next growing season.

Applying the method of planting on the blister after about 20 days can be harvested, grown faster than the bottom about 25 days. However, the process of grape seaweed blisters require higher investment costs, an average of 250 thousand VND / blister. So during this transfer technique, the unionists, youth supports 4 households, each household 4,000 blisters / 1ha; with 100% and 30% of the same amount of materials.

Currently grape algae consumed mainly exported to Japan, Taiwan and some major cities in the country. With the advantages outweigh the planting bed as high yield, good quality seaweed, seaweed blisters easily move convenient for harvesting and storing seed, hopefully in the near future, seaweed farming method on blister will continue to be expanded, contributing to improved productivity and income for many households.
