肥料是农业增产的重要物质基础.H.11648麻适应性强,比较耐瘦、耐旱,但根系发达,产叶多,需肥量大,比剑麻更耐肥.因此,要使它高产、稳产,就要有充足的肥料,所以必须大抓肥源,实行科学施肥.目前,华南植麻地区主要分布在缓坡台地、中、低丘陵地.按土壤类型划分,广东主要是玄武岩风化的砖红壤、花岗岩风化的沙质土;广西南部为石灰岩风化的石灰土、砂页岩风化的砖红壤土,福建南部主要是花岗岩风化的砖红壤性红壤.这些地区土壤养分状况,以砖红壤较为肥沃,经开垦种植作物后,有机质含量为1.5～3.5%,全氮为0.1～0.2%,全磷为0.05～0.1%,全钾为1.5～2.5%.而红壤土、沙质土、石灰土则比较瘦瘠,
Fertilizer is an important material basis for agricultural production.H.11648 Hemp adaptable, relatively resistant to lean, drought-tolerant, but developed root system, leaves more, to be large, more resistant to fertilizer than sisal.Therefore, to make it high yield Therefore, we must pay great attention to the source of fertilizers and implement scientific fertilization.Nowadays, the southern part of Hong Kong is mainly composed of gentle slope, middle and low hilly land.According to soil types, Guangdong is mainly basalt weathering Brick red soil, granite weathered sandy soil; southern Guangxi limestone weathered limestone, sand shale weathered brick red loam, southern Fujian mainly granite weathering brick red soil red soil nutrients in these areas to brick red soil is more Fertile, reclaimed crops, the organic matter content of 1.5 to 3.5%, total nitrogen is 0.1 to 0.2%, total phosphorus is 0.05 to 0.1%, total potassium is 1.5 to 2.5%, while red soil, sandy soil, lime soil Is relatively thin barren,
