1984年,我团对1,560亩地膜棉指挥田采取以集约经营、主攻单产、提高经济效益为中心的栽培技术措施,平均亩产皮棉达248.8斤,亩利润258.84元,每亩较1983年相同肥力的地膜棉多盈利148.64元.指挥田之所以盈利高,主要是施肥效益提高了.指挥田土壤有机质平均含量为0.94%,速氮34.5ppm,速磷9.6ppm,全期亩施氮肥(折合硝酸铵)52斤,过磷酸钙(农一师生产,含P_2O_58—9%)58公斤,氮磷肥总费用38.46元,创产值447.84元,平均1元钱肥料创产值11.64元,较相同肥力的其它棉田多创产值2.77元.我们对指挥田采用的栽培措施如下.
In 1984, our regiment took 1,560 mu of membrane cotton command field to take the cultivation technique measures of intensive operation, main production and improvement of economic efficiency as the center. The average mu produce 248.8 kg per mu and the profit of mu was 258.84 yuan, the same fertility per acre compared with 1983 Of the mulching cotton profit of 148.64 yuan.The reason why the command field profit high, mainly fertilizer efficiency increased.The commanding field soil organic matter average content of 0.94%, fast nitrogen 34.5ppm, speed 9.6 ppm, the entire period of mu N fertilizer (equivalent to nitric acid 58 kg of superphosphate (produced by Nongyishi, containing P_2O_58-9%), total cost of nitrogen and phosphorus was 38.46 yuan, reaching a value of 447.84 yuan and an average of 1 yuan of fertilizer was worth 11.64 yuan, an increase of 11.64 yuan over the same fertility rate More cotton output 2.77 yuan. We use the cultivation of the command field as follows.
