六枝特区黄胶泥田约六万亩,这类稻田土壤粘重,犁耕性、通透性差,作物生长不好、低产。对这些土壤在改良上习惯采取开沟排水、施有机肥或“客土”掺砂的办法,花工大,不易接受,难于实行。在六枝电厂每天能排出二十多吨的烟囱煤灰;取样经贵州遵义钛厂分析;pH8.6,含全氮0.056%,水解氮3ppm,全磷1.06%,速效磷153ppm, Sixty-odd areas of about 60,000 acres of yellow plastic clay fields, such paddy soil sticky, plowing, poor permeability, poor crop growth, low yield. The improvement of these soils used to ditch drainage, organic fertilizer or “guest soil” mixed with sand approach, large flower workers, not easy to accept, difficult to implement. 20 tons of chimney coal ash can be discharged daily in Liuzhi Power Plant; the samples are analyzed by Zunyi Titanium Plant in Guizhou; pH 8.6, containing 0.056% of total nitrogen, 3ppm of hydrolyzed nitrogen, 1.06% of total phosphorus, 153ppm of available phosphorus,
