唐海县三农场农技人员试验的稻田氮磷全层基施技术,不久前通过了市级鉴定。试验结果表明,氮磷配合全层基施,每亩可增产稻谷50公斤。不仅成穗率,结实率都可提高。而且耐旱、稳产。氮磷肥料也可减少损失30％。1985—1988年,三农场推广氮磷全层基施面积为1.2万亩,连续四年亩产超千斤,共增产水稻560多万公斤。具体方法是:在拖拉机水耙地前,把田间水层调整到适宜机械耙地的程度,按每亩碳酸氢铵25—30公斤,过磷酸钙25—30公斤(或磷酸二铵5.5—6公斤)的使用量,均匀撒施于田面,随后通过拖拉机耙地,搅动土层,使肥料与15厘米深耕层的土壤充分混合,达到全层
Three farms in Tanghai County of agricultural and technical personnel testing of paddy field N and P-based technology, recently passed the municipal appraisal. Test results show that nitrogen and phosphorus with the full-base facilities, rice yield 50 kg per acre. Not only the ear rate, seed setting rate can be increased. And drought-resistant, stable production. Nitrogen and phosphate fertilizer can also reduce the loss of 30%. From 1985 to 1988, the three farms promoted a total area of 12,000 mu of nitrogen and phosphorus based on the basement area, and exceeded four kilos of mu per year for a total of four consecutive years, raising a total of more than 560 million kilograms of rice. The specific method is: in front of the tractor rake, the field of water adjusted to the appropriate level of mechanical rake, according to 25-30 kg per acre bicarbonate, superphosphate 25-30 kg (or diammonium phosphate 5.5-6 Kg) of the amount, evenly sprinkled in the field, followed by tractor rake, stirring the soil, so that fertilizer and deep soil 15 cm deep mixing, reaching full-thickness
