松原地区苏打盐碱水田改良技术初探

Preliminary Study on Improving Technology of Soda Saline-alkali Paddy Field in Songyuan Area

通过研究发现苏打盐碱土壤施用改良剂可有效提升水稻产量,其中化学改良剂对于产量提升效果优于生物改良剂,可有效提升秧苗成活率,降低土壤p H值,降低含盐量。不同改良剂对于产量构成因素提升效果不同。脱硫石膏肥可有效提升重度苏打盐碱水田中水稻每穗粒数和每穴穗数,保证千粒重,从而实现产量提升。

It was found that the application of amendments to soda-saline-alkali soil could effectively improve the yield of rice,and the chemical amendments were better than the biological amendments for yield improvement,which could effectively improve the survival rate of seedlings,reduce the p H value of soil,and reduce the salt content.Different amendments have different effects on the improvement of yield components.Desulphurized gypsum fertilizer can effectively increase the number of grains per panicle and panicle per hole of rice in heavy soda saline-alkali paddy field,and ensure 1,000 grain weight,so as to achieve yield increase.
