高油玉米需磷特性及磷素对籽粒营养品质的影响
Characteristic of Phosphorus Absorption of High Oil Maize and Effects of Phosphor on Its Kernel Quality
摘要
Abstract
Characteristic of phosphorus absorption of high oil maize and effects of phosphor on its kernel quality were studied. The results indicated that phosphorus absorption per plant was 1.427 g, or 86.65 kg phosphor for one hectare of high oil maize. About 47 percent of phosphorus was absorbed before flowering; and 53 percent was after flowering. The peak of absorption was at filling stage 0.74 kg. Phosphor was needed to produce 100-kilogram grain of high oil maize, significantly higher than that of common maize. Total phosphorus absorption in plant was positively correlated with oil content, protein content, oil yield, and protein yield. The pot experiment of phosphorus fertilizer showed that application of phosphor could increased the oil and protein content of the kernel, but the starch content was lightly decreased.关键词
