Abstract:

In order to explore a good fertilization model to improve the fertility of yellow-cinnamon soil in Southern Henan,the characteristics of stable and high yield of wheat-maize rotation system and its relationship with soil nutrients under different fertilization treatments on yellow-cinnamon soil were studied.Based on the long-term experiment since 2012,four treatments were set up:no fertilizer(CK),chemical fertilizer(NPK),chemical fertilizer combined with manure(NPKM)and chemical fertilizer combined with straw(NPKS).Plants and soil samples were collected at maturity stage to determine crop yield and soil organic carbon,alkaline nitrogen,available phosphorus and available potassium.The results showed that compared with CK treatment,the crop yield of each fertilization treatment was significantly increased,the yield of wheat was increased by 53.70%—64.50%,and the yield of maize was increased by 44.54%—58.31%.The yield of NPKM treatment was the highest(wheat 8 162.61 kg/ha,maize 8 836.33 kg/ha),and there was no significant difference between NPKS and NPKM treatments.The yield sustainability index(SYI)of NPKM treatment was the highest,and the SYI values of wheat season and maize season were 0.84 and 0.82,respectively.The crop yield and its SYI value both showed NPKM>NPKS>NPK>CK,indicating that chemical fertilizer combined with organic materials could significantly increase crop yield and its sustainability.At the same time,different fertilization treatments could improve soil nutrients to varying degrees,among which NPKM treatment had the most significant improvement effect.The relationship between crop yield and soil nutrients was analyzed.The relationship between crop yield and soil nutrients was analyzed.There was significantly positive correlation between crop yield and soil organic carbon(SOC),available nitrogen and available phosphorus contents,among which the correlation between crop yield and SOC was the most significant.With the increase of soil organic carbon content,the SYI value of crops increased first and then stabilized,and the inflection point was 15.15 g/kg.To sum up,the application of chemical fertilizer combined with manure can significantly increase crop yield and soil nutrients,and maintain high crop yield sustainability.It is a recommended fertilization model to achieve sustainable production of soil-crop system in yellow-cinnamon soil ecological zone.
