不同区域作物适宜的抑制剂施用量探究

Study of Suitable Application Amount of Inhibitors for Crops in Different Regions of China

为了探究抑制剂在不同地区和作物上的适宜添加量,本研究选取中国华南、华东、华中、西南、西北、东北地区的代表性作物,采用田间试验的方法,探究不同抑制剂施用量对作物产量和增产率的影响。研究结果表明,华南地区茶树和龙眼的抑制剂适宜用量分别为7.5‰和8‰,增产幅度分别为6.94%和24.92%。华东地区冬小麦、夏玉米和春花生抑制剂适宜用量分别为6‰、7‰和5‰,增产幅度分别为14.30%、10.98%和12.17%。华中地区水稻抑制剂适宜用量为12‰,增产幅度为8.74%。西南月季和香石竹的抑制剂适宜用量分别为8‰和7‰,增产幅度分别为16.67%和12.10%。西北苹果和冬小麦的抑制剂适宜用量均为7‰,增产幅度分别为27.83%和3.63%,西北春玉米的抑制剂适宜用量为5‰,增产幅度为1.97%。东北玉米的抑制剂适宜用量为9‰,增产幅度为7.67%。总的来说,抑制剂在西北地区粮食作物(玉米、小麦)的增产效果弱于其它地区,水田的抑制剂推荐使用量(12‰)高于旱地(5‰~9‰),且抑制剂在中国各个地区均能产生明显的增产效果,具有显著的增产节肥作用。

In this study, the representative crops of South China, East China, Central China, Southwest, Northwest and Northeast China were selected to study the effect of different inhibitors on crop yield and yield by using field test methods. The results showed that the suitable dosage of inhibitors for tea and longan in North China was 7.5‰and 8‰, respectively, and the yield increases was 6.94% and 24.92%, respectively. The suitable dosage of inhibitors for winter wheat, summer maize and spring flowering in East China was 6‰, 7‰ and 5‰, respectively, and the yield increases was 14.30%, 10.98% and 12.17%. The suitable dosage of rice inhibitor in Central China was 12‰,and the yield increase was 8.74%. The suitable dosage of inhibitors for Chinese rose and carnation planted in southwest China was 7‰ and 8‰, respectively, and the yield increases was 16.67% and 12.10%, respectively. The suitable dosage of inhibitors for apple and winter wheat in northwest China were both 7‰, and the yield increases was27.83% and 3.63%, respectively. The suitable dosage of inhibitors for spring maize in northwest China was 5‰ and the yield increase was 1.97%. The suitable dosage of inhibitors for maize in the northeast China was 9‰ and the yield increase was 7.67%. In general, the yield increasing effect of inhibitors on the grain crops(maize and wheat) in Northwest China is weaker than that in other regions, and the recommended dosage of inhibitors in paddy field(12‰) is higher than that in dry land(5‰-9‰). Above all, it is clear that the inhibitor has evident growth promotion effect on plants in all regions of China, which has significant effect on yield increasing and fertilizer saving.
