| 摘 要： | 旱地红壤施用NPK化肥,甘蔗仍不能正常生长;配施厩肥,甘蔗株高可提高9％—26％、平均茎粗增加0.1—0.4cm,平均单茎重增长0.17—0.43kg,蔗茎糖分含量也有所上升.施用厩肥可改良旱地红壤结构,改善根系生长的环境条件、根系生长量增加,从而扩大根系营养面积.旱地红壤施用NK、NP化肥,大豆干物重与对照差异不显著;施用NPK化肥仍不能平衡供给大豆所需养分、植株矮小,根系结瘤少;配施厩肥,大豆植株总吸氮量可增加30％—50％,吸磷、钾量可提高1—2倍,大豆干物重提高27％—60％.

| Abstract: | Arid red soil is one of the low yield soils in Fujian Province. Sugar growth was unhealthy in applying NPK chemical fertilizer to arid red soil. The plant height, mean stalk diameter, mean weight per plant of sugar in combined of application barnyard manure and chemical fertilizer were more 9%-26%, 0.1-0.4 cm and 0.17-0.43 kg than that of application chemical fertilizers, respectively. Sucrose content in stem was also increased. The structure in arid red soil and the condition of roots growth were improved after application barnyard manure, which the amount of roots growth was increased and the area of root uptake nutrients was extended. The variance between weight of soybean plant dry matter in application NK, NP chemical fertilizers and check were not significant. Soybean can not obtain various nutriets needed for them growing in application NPK chemical fertilizers, which plant heigh were shorter and root nodules were less. The amount of uptake NPK by soybean and the weight of plant dry matter in combined application of barnyard manure and NPK fertilizers were more 30%-50%, 1-2 times, 27%-60% than that in application of NPK fertilizers, respectively. |
