摘要
2012年受台风"布拉万"影响吉林省玉米乳熟期大面积根倒伏。针对玉米倒伏进行倒伏后扶直及不同扶直时间的产量对比研究。结果表明,台风造成倒伏玉米平均减产10.16%～24.43%;3 d内及时扶直可挽回产量损失11%;扶直抢救在考虑倒伏后不同时间段的同时也要考虑土壤含水量,扶直以20 cm土层体积含水量超过25%的效果最好。
Large area of maize lodged during milk stage owing to the typhoon of Bolaven. The yield comparison was studied by lifting up maize in different time. The results showed that the average yield reduction of lodging maize reached 17.29%. The yield could decrease loss about 10.16%-24.43%the plants were lifted up within three days. Soil moisture is also very important while lifting up plants, it is the optimum time for lifting up maize plants when the soil moisture is over 25%.
