摘  要：
丘陵红壤地种植的红麻,其主茎日高生长量具有两个旺长高峰,它的出现并不是麻株自身的生长特性,而主要是由于红壤地间歇干旱等原因所造成。因为其高峰期正好出现在土壤水分含量的3个高峰之间鞍部区域的前沿。测定表明,伏旱季节红麻苗,在0～10 cm的土壤水分含量,若高于14％仍可正常生长,如低到10％～11％即会产生萎蔫现象。试验结果还表明,每公顷施N 180kg、P_2O_590ks、K_2O270kg和N 180kz、P_2O_560kg、K_2O300kg的两个处理,在萎蔫含水量、根系生长、抗旱能力、经济性状总效应等方面的表现,均比其它处理为佳。因此,为红麻水肥管理,特别是氮磷钾的用量和配比提供了实践依据。

摘  要：
The daily increase of the height of the main stems of the bluish dogbane (Hibiscus cannabinus), planted on the hilly red soil, had two peaks of growing season. Since these peaks occurred just before the two nadirs on the soil moisture content curve, the occurrence of these growing peaks was not one of the intrinsic growing characteristics of the bluish dogbane plants; but was caused mainly by the intermittent droughts of the red soil. The resuits indicated that in the hot summer, if the soil moisture content of the top soil (0～10cm) was above 14%, the plants could grow normally; if it was about 10%～11%, the plants wilted. The results also showed that in two of the fertilizing treatments (using 180kg N, 90kg P_2O_5, and 270kg K_2O per hectare, and using 180kg N, 60kg P_2O_5, and 300kg K_2O per hectare, respectively), the wilting coefficient, the root growth, the drought resistence, and the economic properties of the plants were better than those of other treatments. These resuits had provided a pratical basis for the management of the soil moisture and fertilization, especially the management of the fertilizers of N, P, and K, in the production of bluish dogbane.
