北流农业历来走在广西的前列,1988年就开展了配方施肥工作,大力推广节氮增磷钾科学施肥技术,水稻产量稳步增长,并在广西率先实现“吨谷市”,成为水稻高产之乡。近年来,农民为了追求高产,化肥施用量越来越大,据调查,农民种稻平均每亩施纯氮15kg、磷7kg、钾6kg。由于长期大量施用 Beiliu agriculture has always been at the forefront of Guangxi. In 1988, a formula fertilization work was carried out to promote scientific and fertilizing technologies using nitrogen, nitrogen, phosphorus and potassium. The output of rice increased steadily and took the lead in Guangxi to realize the “Tung Valley” township. In recent years, farmers in pursuit of high yield, increasing the use of chemical fertilizers, according to the survey, farmers planted rice per acre nitrogen 15kg, phosphorus 7kg, potassium 6kg.
