以玉米品种郑单958为试验材料,通过盆栽试验,研究生物炭颗粒、炭基肥及普通化肥对玉米物质生产及产量的影响。结果表明,生物炭颗粒处理的最大干物质积累增长速率最低、出现时间较早,过早进入干物质增长速率下降阶段,影响产量的积累,穗重、穗粗、千粒重、理论产量均显著低于对照不施肥处理(CK),而秃尖长和秕粒数却高于CK。炭基肥处理的最大干物质积累增长速率出现的时间较晚,能够使干物质生长直线增长阶段延长,生育后期干物质增长速率仍大于其他处理,对产量的增加均起到了促进作用。炭基肥处理的穗重、穗粗、千粒重、理论产量均显著高于CK。与普通化肥相比,炭基肥处理对产量增加的促进作用更大,各炭基肥施用量中以T2(1 500kg/hm2)处理产量最高。
Taking corn variety Zhengdan 958 as experimental material, the effects of biochar granules, carbon-based fertilizer and common fertilizer on maize material production and yield were studied by pot experiment. The results showed that the maximum dry matter accumulation and growth rate of biochar particles were the lowest, and appeared earlier and prematurely, and the rate of dry matter growth decreased. The effects of yield accumulation, ear weight, ear diameter, 1000-grain weight and theoretical yield were significantly lower than Control without fertilization (CK), while bald length and number of grains is higher than CK. The late onset of maximum dry matter accumulation of carbon-based fertilizers appeared later, which could prolong the linear growth phase of dry matter growth. The growth rate of dry matter at later growth stage was still higher than other treatments, which promoted the increase of yield. Carbon-based fertilizer treatment of ear weight, ear diameter, grain weight, theoretical yield were significantly higher than CK. Compared with the conventional fertilizers, the carbon-based fertilizers promoted the increase of yield more, and the yield of all the carbon-based fertilizers was the highest with T2 (1 500kg / hm2).
