Abstract:
Taking head lettuce as test materials,microplot field experiment was conducted and the fertilization treatments included conventional fertilizer CF (total chemical nutrient 566.25 kg·hm-2) and fertilizer reduction treatments JF1 (total chemical nutrient 288.45 kg·hm-2) and JF2 (total chemical nutrient 166.20 kg·hm-2).The effects of different treatments on lettuce yield,quality,nutrient absorption,soil microbial quantity,and residual nutrients in soil were studied,in order to provide reference for the optimal fertilizer application plan of the production of lettuce in protected areas.The results showed that compared with CF,the biological yield of lettuce under JF1 treatment increased by 0.93%,but the economic yield decreased by 8.27%,the net economic benefit decreased by 9 200 RBM·hm-2,the difference was not significant (P>0.05),while the biological yield,economic yield and net economic benefit in JF2 treatment decreased by 11.63%,30.51% and 42 200 RMB·hm-2 (P<0.05).The vitamin C content of lettuce under JF1 and JF2 treatments were increased by 4.65% and 10.73% (P<0.05),respectively,and the nitrate content was significant by 20.36% and 31.46% (P<0.05),respectively.The nitrogen uptake amount of lettuce under JF2 treatment was reduced by 27.11% compared with CF treatment (P<0.05).After the experiment,the soil nitrate content at depth of 0-20 cm,20-40 cm and 40-60 cm under JF1 and JF2 treatments was 81.77%,59.84%,66.56% and 87.54%,36.01%,70.02% lower than that under CF treatment,respectively.The number of soil bacteria in JF1 and JF2 treatments were decreased by 10.26% and 9.23%,and the number of soil fungi were decreased by 23.51% and 6.55%,respectively.Therefore,moderate chemical fertilizer reduction could maintain ideal yield,economic benefits and lettuce quality and reduce nutrient residual surplus.It was suggested that at mediumhigh fertility level farmland,the optimal yield of lettuce could be achieved by applying 15 tons commercial organic fertilizer per hectare,and supplementing chemical nitrogen (N) ,phosphorus (P2O5) and potassium (K2O) at level of 193.8 kg·hm-2,57.9 kg·hm-2,and 189.0 kg·hm-2,respectively.
