不同秸秆腐熟剂的应用效果

目的]研究增施腐熟剂对小麦秸秆腐熟程度、土壤养分、水稻植株性状及产量的影响。方法]试验在大田开展,采用随机区组设计。结果]增施腐熟剂能加速小麦秸秆腐熟进程,第10~20天为秸秆失重率增幅最大的时段;增施腐熟剂处理可以明显提高土壤养分,改善土壤通气性,提高水稻结实率及千粒重,比对照增产4.1%~5.0%。结论]增施1号腐熟剂在加速秸秆分解、提升土壤养分及产量方面的效应明显优于2号腐熟剂。

Study on Application of Different Decomposing Materials for Straws

Objective ] The research aimed to study the effects of decomposing materials on the decomposing degrees of wheat straws, soil nutri- ents, shape and properties of rice and its yields. Method] The trial was arranged in land and was designed with randomized block. Result] The use of the decomposing materials could accelerate the decomposing process of wheat straws, and the rate of weight loss increased by a maximum happened between 10- 20 d. The use of decomposing materials could promote the contents of soil nutrients obviously, improve the ventilation in soils, and promote the seeding rate and the weight of 1 000 grains of rice, and had an increased yield by 4. 1% -5.0% compared with CK. Conclusion] The application results of the decomposing materials which was named NO. 1 was better than NO. 2 regarding the acceleration of the straws decomposing, promotion of the soil nutrients and yield.
