Abstract
Promoting the application of advanced irrigation technology, saving water for the dry crop is one of the important tasks set by the Ministry of Agriculture and Rural Development during the implementation of the restructuring project. agriculture and irrigation with the target that by 2020, having 500,000 ha of upland crops will be applied with advanced irrigation technology and water saving.
The central region is the most drought area in the country, with the potential of extensive sandy soils being used for agricultural development. With efficiency in many aspects has been studied and verified in our country in recent time (saving water, significantly reducing the care and irrigation costs, contributing to increase income, etc...compared to traditional irrigation techniques), the application of water saving irrigation (sprinkle irrigation) for shallow plants in general and for onion in particular is very necessary, should be replicated.
The sprinkle irrigation process for the small spring onion in the central region is one of the main products of the pilot project of the Ministry of Agriculture and Rural Development. "Complete technological solution and integrated advanced irrigation equipment, saving water, low cost for short-term crops, vegetables and industrial crops". The model to improve the rainbow irrigation process for the small spring onion is located in Dien Thinh commune, Dien Chau district, Nghe An province with the scale of 2 ha, is monitored from 2016 ÷ 2017, the results have been completed the sprinkle irrigation process for small spring onion in the central region with the water level of 20 ÷ 35 m3/ha each time; total irrigation water volume for spring crop is 1060 ÷ 1250 m3/ha-crop; summer crop: 860 ÷ 1015 m3/ha-crop; autumn crop 840 ÷ 990 m3/ha-crop; winter crop 640 ÷ 755 m3/ha-crop. It is the scientific basis for the Directorate of Water Resources to issue and apply in the Central Region.
