我区每到冬、春两季,正是蒙古兔严重危害幼树和苗木的时期。它们最爱啃食基径粗3厘米以下的榆树、文冠果、果树、柳树、松树、杨树等的嫩枝和树皮。凡遭受蒙古兔啃食的幼树和苗木,重者死亡,轻者长势不良,给造林、育苗带来了很大的经济损失。 Every winter and spring in our district, it is exactly the period when the Mongolian rabbits seriously harmed saplings and seedlings. They love to eat the tender branches and barks of elm trees, fruit trees, willows, willows, pine trees, poplars and so on under 3 centimeters in diameter. Those who suffer from the Mongolian rabbit grazing saplings and seedlings, the most serious death, the light poor growth, afforestation, nursery has brought great economic losses.
