贵州山区灰肥(草木灰、煤灰、火土灰)十分丰富,给人粪尿与灰肥混贮创造了良好条件。一般认为,人粪尿与灰肥混贮,会造成氮素的损失,不主张推广。但实际上,在农民群众中却很盛行人粪尿与灰肥混贮,有的地方叫“尿窖灰”,有的地方叫“尿灰”,并反映肥效很好。为了深入探讨这个问题,特进行了人粪尿与灰肥混贮后养分变化创研究。 材料和方法 在夏季用草木灰、煤灰和火土灰分别与人粪尿按1:1的比例混贮于田间和盆钵。田间试验20天,盆钵试验60天。田间试验在第20
Guizhou mountain ash fertilizer (ash, coal ash, fire ash) is very rich, giving manure and ash mixed fertilizer to create a good condition. Generally believed that human waste and gray fat mixed storage, will cause the loss of nitrogen, do not advocate the promotion. However, in fact, it is prevalent in the peasant masses that manure is mixed with ash and fat. In some places, it is called “urine pit ash” and in some places “urine ash” and reflects the good fertilizer effect. In order to explore this issue in depth, we conducted a special study on the changes of nutrients after mixed storage of manure urine and ash fertilizer. Materials and methods In the summer with ash, coal ash and fire ash were mixed with human excrement in a 1: 1 ratio in the field and pots. Field test 20 days, pot test 60 days. Field trials at 20th
