生物炭对玉米茎秆性状及产量的影响
Effects of biochar on stalk characters and yield of maize
摘要
Abstract
Field experiments were conducted to study the effects of different amount of biochar application (0, 10, 20, 40, 80 t/hm2 ) on potassium content, stalk morphological characteristics, stalk quality and yield of maize. The results showed that soil applying biochar increased potassium content in each internode of maize stalk, and biochar application resulted in dwarfing of the 3rd~5th internodes at the lower part of maize stalk, increased stalk diameter, enhanced stalk elasticity and rind punc-ture force, increased dry matter accumulation, and strengthened stalks. With the increase of the amount of biochar applica-tion, the effects on potassium content, stalk characters and yield of maize all showed the trend of first increased and then de-creased. Biochar applied at 40 t/hm2 was the optimal application rate, leading to a yield of 13 261 kg/hm2 , which was 25. 99% higher than that of the control. When biochar application was at 80 t/hm2 , its improving effects on potassium con-tent, stalk morphological characteristics, stalk quality and yield of maize slightly declined.关键词
