我国解放以来,施用化肥的种类和数量日多,对提高粮食产量起了很大作用。我地区的化肥施用情况基本与全国相同,特别是七十年代以后,化肥用量由少到多,配合其他农业技术措施,促进了粮食增产(见表)。但近年来盲目多施化肥的现象越来越普遍,肥料利用率下降,经济效益降低。如全州县城关公社大新5队1979年早稻有两块田,前作物均是冬种萝卜昆肥田草,底肥、品种、秧苗相同,只是施化肥情况不同:一块插后12—13天亩施碳铵32斤,亩产毛谷951斤,干

The application of fertilizers in our region is basically the same as that of other parts of the country. In particular, from the seventies onwards, the amount of chemical fertilizer used was reduced from a small number to as much as other agricultural techniques and measures to promote grain production (see table). However, in recent years, the phenomenon of more and more blindly applying chemical fertilizers is more and more common, and the utilization rate of fertilizers is declining and the economic benefits are reduced. Such as Quanzhou County commune Dah Sing 5 teams 1979 There are two fields in early rice, the former crops are winter radish Kun Kun Tian grass, base fertilizer, varieties, seedlings the same, but different fertilizer situation: an inserted 12-13 mu 32 kg of ammonium bicarbonate, gross grain yield 951 kg, dry
