摘要
以上海目前正在推广的商品有机肥为研究对象,以有机无机结合施肥的方式,围绕高产、优质、安全的生产目标,通过田间小区试验,表明在一定量的氮化肥条件下,增施商品有机肥对水稻有显著的增产作用。土壤肥力中等地区,水稻田以基施商品有机肥4500~6000kg/hm^2,再施氮化肥225~255kg/hm^2为宜,从而大幅度地降低氮化肥的用量;通过对稻米品质和土壤分析,明确了增施商品有机肥可提高稻米品质,改善土壤理化性状。
Plot experiments of planting rice were carried out by combined application of inorganic fertilizer and commercial organic fertilizer being presently popularized in Shanghai. The results showed that given a certain amount of chemical nitrogen fertilizer applied, applying the commercial organic fertilizer could significantly increase rice yield. In a mediun-fertility rice field, it was appropri- ate to use 4 500 - 6 000 kg/hm2 commercial organic ferlilizer as basic ferlilizer and apply 225 255 kg/hm2 chemcial nitrogen ferlilizer. The analyses of rice quality and soil showed that the application of the commercial organic fertilizer could improve the rice quality and the physicochemical characters of soil.
