Successfully restored white cotton sedge in Nga Son

The scientific topic "Research on the restoration of white cotton sedge varieties in Nga Son and Thanh Hoa districts" conducted by Thanh Hoa Department of Science and Technology in collaboration with Hanoi University of Agriculture has been achieved since 2008. positive results.

The units implementing the project have selected high purity standing white cotton sedge varieties to be used for recovery according to In vitro and In vivo cultivation procedures. The project also developed a technical guideline on planting and caring for white cotton sedge varieties and building a seedling nursery with an area of ​​500m2 and a group of original seedlings kept in vitro.

In Nga Son district, there are two common sedge varieties: brown cotton sedge and white cotton sedge. Both of these sedge species have been attached to the people for a long time, in which white cotton sedge has many advantages such as high yield, better quality than brown cotton rush, the growth and development process is suitable for the climate and soil conditions of Nga Son land.

White cotton sedge has many outstanding advantages compared to other sedge varieties such as: green sedge body, when split and exposed to white sedge, shiny, flexible, tough, beautiful and durable, good color retention, so customers are very interested in these products made from this sedge. However, over the years due to the unstable consumption market, sedge growers are not interested in papyrus, the process of looking and caring is not guaranteed, making the sedge varieties in Nga Son degenerate. serious.

In order to conserve and develop sedge and rush cultivation, Thanh Hoa Department of Science and Technology and Hanoi University of Agriculture have chosen 6 communes with experience in planting and intensifying good sedge to implement the project.

Mr. Mai Van Ban, a sedge farmer in Nga Thai commune, said: To implement the project to restore white cotton sedge varieties, farmers were supported 8 million VND / ha, participating in training courses to receive intensive techniques new soup. The strength of this sedge is high yield, less pestilent insects, not tinted when it rains heavily. This year, the weather is favorable, it is well cared for, so the average yield is higher than every year, reaching 5 quintals / sao. Price sedge 10,000 -12,000 VND / kg, average income of 5-7 million VND / sao.

The topic of 'Easter with white cotton sedge' has helped farmers in Nga Son region step by step to improve the intensive farming techniques, the productivity of rush plants increased rapidly.

In the communes of Nga Thanh, Nga Lien and Nga Thuy, the area of ​​white cotton sedge has been expanded over 90%, the communes of Nga Thai, Nga Tien and Nga Tan have the area of ​​white cotton sedge accounting for 70% of the total area of ​​sedge. . Currently, the sedge area in Nga Son has reached 3,255 ha, yield of 78 quintals / ha / year, total production of more than 22,588 tons / year.

The results of the project have important implications in the development of sedge planting, thereby promoting the development of craft villages producing sedge in Nga Son district and coastal areas of Thanh Hoa.
