我站三年的试验结果证明:冬小麦在秋季进行灌溉一次到返青时植株生长良好,没有死亡.而不灌者在溶雪后植株下部叶片一片枯黄(但整个植株很少死亡),但提高产量2.4—6.9%.其具体资料分述于后,以供参考:一、秋灌与否返青后植株生长状态:根据历年观察证明,凡进行秋灌一次以上者,返青后植株正常生长,但在早春第一水前(接近拔节)植株就表现较黄.而秋季未灌者,溶雪后植株下部叶片普遍死亡.
The results of my three-year trial showed that the winter wheat plants grew well and did not die when they were irrigated in the autumn and then returned to the green, while the leaves of the lower part of the plants were yellowish after the snow-melting (but the whole plant rarely died) 2.4-6.9% .The specific information is described in the following, for reference: First, the autumn irrigation or not after returning to green plant growth status: According to the calendar year observation shows that those who conduct more than one fall irrigation, green plants after the normal growth, but in Early spring before the first water (close to jointing) plants on the performance of the yellow, while those who were not irrigation in autumn, snow plant leaves lower after the general death.
