摘要:

为探究不同土壤改良剂及其用量对舟山滨海盐碱地改良效果与作物生长的调控作用,2023年于舟山市普陀区滨海盐碱地选取高粱为供试材料,以不施土壤改良剂为对照,选用硫酸钙、商品有机肥、生物炭等3种改良剂,系统对比不同改良剂种类与用量对盐碱地理化性质及高粱生长的影响。结果表明,施用商品有机肥和生物炭对盐碱地改良效果较好,以T9处理(生物炭高施用量,每667 m2施用800 kg)表现最好。T9处理的高粱穗长、穗重和千粒重最高,籽粒的全氮和全磷含量最高。与CK相比,T9处理的土壤有效磷含量显著(p<0.05)提高,说明生物炭高用量对舟山滨海盐碱地具有较好的改良效果。

Abstract:

To investigate the effects of different soil amendments and application rates on the improvement of coastal saline-alkali soil in Zhoushan and their regulation on crop growth,sorghum was selected as the experimental material in coastal saline-alkali soil of Putuo District,Zhoushan City in 2023. Using no soil amendment as the control,three amendments,calcium sulfate,commercial organic fertilizer,and biochar,were employed to systematically compare their effects on the physicochemical properties of the saline-alkali soil and sorghum growth.The results showed that application of commercial organic fertilizers and biochar improved saline-alkali soil,with the T9 treatment(high application rate of biochar at 800 ke per 667 m2)performing the best. The T9 treatment resulted in the longest ear length,highest ear weight,and maximum thousand-kernel weight for sorghum,as well as the highest total nitrogen and phosphorus content in sorghum grains. Compared with CK,soil available phosphorus content were significantly(p<0.05)increased,indicating that high application rate of biochar was highly effective for improving coastal saline-alkali soil in Zhoushan.
