The method of intermittent irrigation in agricultural experimental station has been successful in saving water and increasing yield of rice.
The water situation is grim, and the rice farming industry, which relies heavily on water resources, bears the brunt. Hualien organic small farmers use intermittent irrigation to make rice dry and dry alternately, saving 30% of the water for cultivation and increasing the rice harvest.
The green farmland makes people relaxed and happy, in case of drought, this scene is difficult to see again. In the face of extreme weather, organic farmers in Hualien use intermittent irrigation to save water.
Organic farmer Xie Jinggui: "this natural farming method is to make it dry and dry, that is, at the junction of dry and dry, it has the most vitality, so if you stay in the water, on the contrary, the farmers will say that the older generation will talk about soft feet, but the rice will not be so strong." "
Intermittent irrigation is a way of alternating dry and dry. After irrigation to a depth of about 5 cm, the irrigation is stopped, then the water decreases slowly as the rice plant evaporates or leaks, and the next day it is reirrigated to a height of 5 cm. The most important thing is to give enough water from heading and flowering to the full maturity of the grain.
Organic farmers in Hualien have been using this intermittent irrigation for eight years, and the experimental results are quite good.
Organic farmer Xu Zhengde: "it can save about 30% to 40% of the water used for irrigation, and then its actual harvest, because its roots develop very well, so the harvest will also increase, which should be increased by more than 10%." "
In recent years, uneven distribution of water resources has occurred from time to time. Intermittent irrigation for rice proposed by the Agricultural Test Institute is not only the effective use of water resources to ensure rice production in Taiwan, but also the trend of agricultural development in the future.
