Successful application of tea sprinkler model with rotary valve

To help people in tea production in the area to actively irrigate, reduce pests, reduce labor and increase productivity, product quality, Department of Agriculture and Rural Development in Dai Tu district, Thai Nguyen province has Successful implementation of the project ' Application of science and technology to build a model of tea irrigation by rotating valves'.

Currently, most tea growers still use the method of irrigation with a direct pump system, causing waste of water, soil erosion, productivity, quality and efficiency are not high.

The project to build a model of rotating irrigation with tea valves helped farmers take initiative in irrigation water in tea production, contributing to improving crop productivity and quality, increasing income for workers.

In addition, when using the method of sprinkling tea with the valve, people can combine spraying with plant protection and liquid microbial fertilizer, thereby increasing the absorption capacity for the tea plants that are dissolved and absorbed. right down to the ground.

Water tea

The model of irrigation with rotating valves using sprinkler technique is a technique to bring water to plants on the ground in the form of artificial rain thanks to the appropriate equipment for rain spraying (rain beam).

This method is increasingly popularized and widely applied, especially in countries with developed industries.

After one year of experimenting on 10 hectares of tea in Phu Lac and Tien Hoi communes (Dai Tu and Thai Nguyen districts), the method of tea irrigation with rotating valve technology has brought about practical results.

Mr. Le Thanh Son, Head of the Department of Agriculture and Rural Development in Dai Tu district, said that the model of rotating tea by irrigation valve has brought high efficiency, especially for places where water is scarce and proactive in producing winter tea. limit water loss due to evaporation, in accordance with the growth of crops, without eroding soil.

Compared to using the traditional irrigation method, the method of irrigation by rotating valves only uses 1/4 of water, the irrigation time is reduced by 2/3, ensuring the same humidity, actively irrigating the water according to the right time and requirements of tea plants.

Thanks to the successful application of the rotating valve model, the product productivity has increased by 40kg / ha. On the same unit, if irrigated by rotating valves, the higher income of manual methods is VND 9,934,000 / ha / year.

Currently, Thai Nguyen province is replicating the model in Phu Luong district with an area of ​​5 hectares of tea, in Quyet Thang and Tuc Tranh hamlets.

The project will be implemented within 12 months, with a total investment of over VND 400 million, of which VND 200 million from the State Budget.
