ABSTRACT: Unreasonable fertilizer input and low fertilizer
utilization seriously restrict the development of maize in Heilongjiang
province. In this paper, the effects of biochar
based fertilizer on the nutrient content of acidic soil and corn yield
in Heilongjiang province were studied. The random block design was adopted, and
seven treatments were set with four repetitions. The results showed that
biochar based fertilizer increased the soil organic matter content in the
mature stage of maize. The S1 (The biochar biobased fertilizer treatment 1 in
acid soil), S2 (The biochar biobased fertilizer treatment 2 in acid soil), and
S3 (The biochar biobased fertilizer treatment 3 in acid soil) treatments
organic matter contents increased by 15.96%, 11.06% and 10.03% than SCK (The Acid
Soil Control Check) respectively. The total nitrogen, total phosphorus, total
potassium, total calcium of S1 treatment corn plants increased 16.81%, 15.34%,
31.20% and 22.96% than SCK. The S1 treatment increased the yield of corn, which
was 1.94% higher than SCK. There was no significant difference between the
yield of S2, S3 with SCK treatments, which achieved the effect of fertilization
reducing.
