Abstract:
Taking greenhouse tomatoes as the experimental material,a trial was conducted on the water and fertilizer cultivation under moistubEirrigation.Seven treatments were set in the experiment,included CK without fertilization,low level inorganic fertilizer T1 (N∶P∶K=150∶60∶120 kg·hm-2),medium level inorganic fertilizer T2 (N∶P∶K=300∶120∶240 kg·hm-2),high level inorganic fertilizer T3 (N∶P∶K=450∶180∶360 kg·hm-2),and low level inorganic fertilizer respectively applied with low level organic fertilizer M1 (75 kg·hm-2),medium level organic fertilizer M2 (225 kg·hm-2),and high level organic fertilizer M3 (375 kg·hm-2),the effects of reducing inorganic fertilizer and applying soluble organic fertilizer on soil nitrate nitrogen and tomato growth were studied,in order to provide reference for green and efficient production of greenhouse tomatoes.The results showed that a small amount of inorganic fertilizer combined with organic fertilizer could significantly reduce the accumulation of soil nitrate nitrogen,and could also keep the tomato in a good growth condition and improve the quality of tomato fruit.Among them,M2 treatment was the best fertilization proportion because of its low accumulation of soil nitrate nitrogen,good growth and optimal fruit quality.
