1、施用RE对上述五种土壤酶都有影响,促进了能量的转化和养分的新陈代谢。2、用RE浸种和不同生育期浇灌RE,对这五种土壤酶活性的影响是激活作用大于抑制作用,生育前期大于生育后期,从而使小麦苗期有较多的能量和可溶性养分被小麦吸收利用,使小麦有效分蘖多,为增产打下基础。3、本试验证明:用RE浸种后,在拔节前期浇灌RE效果最好,产量最高,其增产原因主要是有效分蘖数的增多。
1, the application of RE on the five soil enzymes have an impact, and promote energy conversion and nutrient metabolism. Soaking RE and watered RE at different growth stages affected the activity of these five kinds of soil enzymes more than the inhibition effect, and the early growth period was greater than the later growth period, so that more energy and soluble nutrients were absorbed by the wheat seedlings Use, so that more effective tillering of wheat, lay the foundation for increased production. 3, the test shows that: RE soaked with RE, the best effect of watering RE in the pre-jointing stage, the highest yield, the main reason for the increase is the increase of effective tillers.
