人工腐熟的粪肥配施对糯玉米光合特性及产量构成的影响

Effects of Applying Artificial Maturity of Manure on the Photosynthetic and Yield of Waxy Maize

本文通过基肥+追肥的施肥方法,研究了粪肥的不同配施对糯玉米光合特性及产量的影响.结果表明:通过粪肥的合理配施,糯玉米的净光合速率、气孔导度、蒸腾速率的最高值比对照分别高出25.6%、81%、69.9%,表明粪肥的合理配施能显著增加糯玉米的净光合速率、气孔导度、蒸腾速率;为糯玉米的生长提供了各种必须的营养元素,对糯玉米的鲜穗产量的增产有明显的影响作用。

By the method of basic fertilizer ＋ top fertilization, studied the effect of photosynthetic characteristics and yield of waxy maize by the different of applying manure. Results showed that： by the rational applying of manure, the highest of net photosynthesis, stomatal conductance and transpiration rate of maize higher than 25.6%、81%、69.9% respectively , by rational applying manure, increased the et photosynthesis, stomatal conductance and transpiration rate of maize, offered a variety of essential nutrients for the growth of waxy maize, the significantly effects of increasing the fresh yield waxy of maize.
