| 摘 要： | 为改变贵州喀斯特地区农产品产出率低、品质差的现状,从喀斯特生态地质环境脆弱、土壤缺少微量元素等特征入手,利用富含矿物元素的硅酸盐岩,开发生产多元素液态矿物肥料,补偿喀斯特地区农作物生长需要的矿物营养元素。2002年以来经100多个农户及贵州省各地土肥站、农业科研生产部门在贵州喀斯特地区十几个县市进行了700多亩种植试验,获得了农作物产量增加和农产品质量提高的效果。施用多元素液态矿物肥种植的水稻、玉米、辣椒、油菜、烤烟、水果及蔬菜等20多个农作物,其90%以上的作物增产超过5%,70%增产超过10%,农产品的蛋白质提高1～2个百分点,稻谷支链淀粉提高2.7%,果实的外观色、香、味、形得到明显改观。实践证明施用多元素液态矿物肥料是提高喀斯特地区农产品产出率的新途径。

| Abstract: | In order to alter the existing state of low output and improve the quality of agriculture products, the necessary element for crops growing is compensated by applying multi-element fluid fertilizers developed from silicate rocks in the light of weak ecology in karst geo-environment and lack of micro-element in karst soil. The natural fluid fertilizer can supply mineral nutrition to plants and compensate nutrition element for calcareous soil.This multi element fluid fertilzer was used by over 100 peasant households and some agriculture research and productive departments to more than 700 mu land and over 20 types of crops, including rice, corn, hot pepper, rape, tobacco, fruit and vegetable, etc. in tens karst counties from the year 2000 to now.It's shows that crops yield rise obviously after fertilizeration, the production of 90% crops applied the fertilizer rise by more than 5%, and 70% of those increase by 10% or more. Additionally, the result shows that the quality of products are noticeably improved by applying the natural fluid fertilizer, which protein content increase by 1% to 2%.Not only the amylopectin of rice increase by 2.7%, but color, sweet smell, taste and form of fruits obviously get better. It is proved that this new method is an important way to raise output of agriculture products in karst region. |
