Abstract:
Taking ‘Liaoyuan Doli’ tomato planting soil as test material,six different fertilizer treatments of vermis manure (VM) instead of chemical fertilizer (CF) were set up in solar greenhouse.Without fertilizer treatment(CK) was used as control,100CF and 75CF treatment as contrast.Soil phosphorus was classified by the method of modified Hedley phosphorus classification,and the effect of different amounts of vermis manure instead of chemical fertilizer on phosphorus composition and tomato yield in protected soil were studied.The results showed that,1) Compared with 100CF treatment,treatment using 75CF+25VM increased soil total phosphorus content obviously by more than 17.7%.75CF+25VM and 100VM increased Resin-P content similarly by 14.9% and 16.9% respectively.75CF+25VM increased NaHCO3-Pi outstandingly by 58.9%.Effect of different treatments to the content of NaOH-Pi were similar with that of NaHCO3-Pi.Different treatments decreased the content of DHCl-Pi,75CF+25VM treatment decreased the lowest by 3.38%.2) Compared with 100CF treatment,the contents of two forms of organophosphorus in NaHCO3-Po,NaOH-Po were decreased in all treatments.100VM treatment decreased the smallest by 17.8%.There was no significant difference in the content of NaOH-Po between the treatment of 75CF+25VM and 100VM.The response of Residual-P content to different fertilizer treatments was not obvious.3) Compared with 100CF treatment,75CF+25VM treatment increased tomato yield by 25.7% on average.The results showed that under the condition of equal nutrients,75CF+25VM treatment was more beneficial to increase the content of total phosphorus and inorganic phosphorus in protected soil,promote the transformation of organophosphorus to inorganic phosphorus,and improve the availability and utilization rate of phosphorus.The yield of tomato treated with 75CF+25VM was much higher than that of other treatments,which demonstrated the reliability of the above results.
