我院机械化养猪场的猪粪资源丰富,日产量在10吨以上。以往用猪粪上地,在培肥地力、持续增产方面,取得了明显的效果。由于粪量多,运输劳、畜、机力占用多,除以猪粪作基肥外,水田还按三段五次模式施用化肥,施肥劳动效率低,生产成本高,难于适应高产高效农业的要求。为此,我院生产处在1992年试制有机—无机复肥,在水稻移植前一次施用,以后不再追肥。这种复肥是以腐熟猪粪为有机载体,根据水稻需肥特点,用化学氮、磷、钾、
Our hospital mechanized pig farm pig manure is rich in resources, the daily output of 10 tons or more. In the past pig manure on the ground, fertility in fertility, continued to increase production, and achieved remarkable results. Due to the large amount of manure, more labor, livestock and machinery are transported, and more pig manure is used as base fertilizer. The paddy field also uses chemical fertilizers in three stages and five modes. The fertilization has low labor efficiency, high production cost and is difficult to meet the requirements of high yield and high efficiency agriculture . To this end, our hospital production in 1992 trial organic - inorganic compound fertilizer, a time before the rice transplant application, no longer dressing. This compound fertilizer is based on the maturity of pig manure as an organic carrier, according to the characteristics of rice needs fertilizer, with chemical nitrogen, phosphorus, potassium,
