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.

Highlights

Heilongjiang province is an important commodity grain base in China
The results showed that biochar based fertilizer increased the soil organic matter content in the mature stage of maize
Application of biochar base fertilizer is better than other treatments in improving the content of soil organic matter, total potassium and available potassium [15]

Summary

Introduction

Heilongjiang province is an important commodity grain base in China. It is urgent to update the original fertilizer application mode with new fertilizers. As a new type of fertilizer, biochar base fertilizer can reduce the use of chemical fertilizer, improve soil physical and chemical properties, promote crop quality growth and yield increase, reduce agricultural production cost, and effectively increase soil fertility [1] [2]
