近年来,国外将含铬、镍、钴、钛、钒、磷、锰、铁及多种微量元素的超基性—基性岩及其风化产物作为肥料,用来促进农作物增产,提高农产品质量,获得良好效益。 据报道,将蛇纹岩与工业生产的主要化肥一起施用,可提高甜菜块根产量20—25％(2,200—3,200公斤/公顷),并使含糖量提高0.5—0.7％;也可以提高葡萄及其它农作物的含糖量。而滑石—蛇纹石—菱镁岩可以促进番茄根系的生长。在生草化土上所进行的实验室、盆栽和田间试验表明,辉长岩和绿帘石—绿泥石片岩,在氮磷钾肥为背景的情况下,可提高农作物产量8—30％,并改
In recent years, ultra-basic-mafic rocks and their weathering products containing chromium, nickel, cobalt, titanium, vanadium, phosphorus, manganese, iron and various trace elements have been used abroad as fertilizers to promote the increase of crop yield and the quality of agricultural products , Get good benefits. It has been reported that the application of serpentinite together with the major industrialized fertilizers can increase the yield of beet root by 20-25% (2,200-3,200 kg / ha) and increase the sugar content by 0.5-0.7%. It is also possible to increase the yield of grapes and Other crops sugar content. The talc - serpentine - magnesite can promote tomato root growth. Laboratory, potted and field trials conducted on grassy soils show that gabbro and epidote-chlorite schist can increase crop yields by 8-30% in the context of NPK fertilizers, And change
