黑龙江省玉米种植面积已超过600万hm2,其中黑龙江省西部、北部等传统旱区占30%以上,由于干旱造成的玉米减产15%以上。30%2-(乙酰氧基)苯甲酸可溶性粉剂(旱立停)对减少植物叶片水分蒸腾,保持植物水分,增强植物抗旱能力,促进作物抗旱节水等方面的效果明显。为了探索抗旱节水的新途径和方法,本试验通过对不同使用方法及不同剂量的30%2-(乙酰氧基)苯甲酸可溶性粉剂(旱立停)在黑龙江省玉米抗旱增产效果和对玉米安全性研究,确定了30%2-(乙酰氧基)苯甲酸可溶性粉剂(旱立停)在黑龙江省玉米抗旱增产效果最佳的剂量及使用方法,为生产上大面积推广提供科学依据。
Heilongjiang Province has more than 6 million hectares of corn acreage, including more than 30% of the traditional arid regions such as the western and northern Heilongjiang Provinces, and more than 15% of the maize crop due to drought. The effect of 30% 2- (acetoxy) benzoic acid soluble powder (dry stand) on reducing the transpiration of plant leaves, maintaining plant moisture, enhancing plant drought resistance, and promoting drought resistance and water conservation of crops are obvious. In order to explore new ways and methods of drought-resistant and water-saving, this experiment adopted different methods and different doses of 30% 2- (acetoxy) benzoic acid soluble powder (drought stand) in Heilongjiang Province, drought-resistant corn yield and corn Safety study to determine the optimum dose and use of 30% 2- (acetoxy) benzoic acid soluble powder (drought stand) in drought resistance and yield increase of corn in Heilongjiang Province, to provide a scientific basis for the promotion of large-scale production.
