城郊土地复垦技术及种植豌豆培肥效果评价研究
Study on Reclamation Technology and Evaluation of Fertilization Effect of Pea Planting on Suburban Land
摘要
Abstract
To provide a technical scheme and reference basis for land reclamation in China,the suburban reclaimed land in Dongxihu District of Wuhan City was selected in this research,and the soil improvement situation of reclaimed land for 1 year and 2 years was compared with the standard agricultural land.The man-machine combination method was used to clean up the construction waste and cement stones on the surface layer(0-50 cm)of reclaimed land,and the horizontal ground leveler was used to level the plot.According to the soil characteristics,sand soil or lake mud and pond mud were backfilled,and the pH of reclaimed land soil was adjusted.Planting peas to add fertilizer to the fields could increase the organic matter content of the soil and improve the soil environment and fertility.The results showed that the pH of the soil was adjusted to 7.5 after reclamation 1 year,and pH 7.0 after reclamation 2 years,which was close to the average pH 6.7 of the control test land.The organic matter content of the soil was 168.40‰ in the control test land,15.10‰ in the reclamation 1 year and 195.06‰ in the reclamation 2 years,the soil fertility reached the level of standardized agricultural land.The uniformity index of pea plant height in the 2 years of reclaimed land was 11.93,which was close to 13.75 in the test control land,which indicated that the soil environment and fertility status of the reclaimed land had been significantly improved after reclamation 2 years and the nutrient composition was highly homogenized,the reclaimed land reached the level of standardized agricultural land and can be converted into cultivated land.关键词
