| 摘 要： | 笔者采用定点监测方法,开展了稻草持续还田腐熟效果研究。结果表明:连续3年稻草还田腐熟,土壤有机质增加,容重降低,土壤理化性状得到改善,水稻产量增加。与无稻草还田相比,水稻增产590.67~774.00 kg/hm~2 ,增长7.14%~9.36%;土壤容重降低0.02~0.03 g/cm~3,降低1.53%~2.30%;土壤有机质增加0.64~1.34 g/kg,增长1.97%~4.13%;土壤碱解氮、有效磷、速效钾含量均有不同程度提高。经方差分析,常规施肥加"谷霖"腐秆剂的稻草还田处理与常规施肥无稻草还田处理之间土壤容重、土壤有机质、土壤碱解氮之间含量差异均达到显著水平,有效磷含量差异达极显著,其余各处理之间土壤理化性状指标之间差异不显著(P0.05)。稻草持续还田腐熟不仅能培肥地力,而且增产增收。

Site Monitoring of Compost Effect Under Continued Straw Returning to Field |
| |
| Abstract: | In this paper, site monitoring method was used to study the compost effect of continued straw returning to field. The results showed that under continued straw returning to field for 3 years, soil organic matter increased, bulk density decreased, soil physical and chemical properties were improved, and the rice yield increased. Compared with no straw returning, rice production was raised by 590.67- 774.00 kg/hm2, namely 7.14%-9.36%; soil bulk density decreased by 0.02-0.03 g/cm3, namely 1.53%-2.30%; soil organic matter increased by 0.64- 1.34 g/kg, namely 1.97%- 4.13% ; soil alkali- hydrolyzable nitrogen, available phosphorus and available potassium content were improved in different degrees. Through analysis of variance, conventional fertilization quick composting of rice straw returning treatment and conventional fertilization without straw returning treatment between the soil bulk density, soil organic matter, soil nitrogen differences between available phosphorus content was extremely significant, the difference between soil physicochemical properties index was not significant between other treatments (P > 0.05). The continued straw returning to field could not only enhance the fertility, but also increase production and income. |
