摘要:

短链低聚磷酸铵是一种优质的磷肥,近年来在农业生产中逐步得到应用。采用聚磷酸铵为基础肥源生产出含聚磷酸铵水溶肥料,通过田间试验研究其喷施对西瓜和水稻种植的影响。试验结果表明:喷施含聚磷酸铵水溶肥料后,能明显促进西瓜藤蔓生长且叶片较大,增加了光合作用的面积,有助于提高西瓜中心糖度,与对照相比增产421.3 kg/亩,增产率10.26%;水稻产量516.2 kg/亩,比对照增产33.8 kg/亩,增产率7.01%。

Abstract:

Short-chain ammonium oligophosphate is a kind of high-quality phosphate fertilizer, which has been gradually applied in agricultural production in recent years. Using ammonium polyphosphate as the base fertilizer source, the water-soluble fertilizer containing ammonium polyphosphate is produced, and effects of its spraying on planting of watermelon and rice are studied through field experiments. The experimental results showed that spraying water-soluble fertilizer containing ammonium polyphosphate can significantly promote the growth of watermelon vine and has larger leaves, and increase the photosynthetic area, improving the central sugar content of watermelon, which increases yield by 421.3 kg per mu than control group, with 10.26% yield increase rate, and the yield of rice is 516.2 kg per mu, which increases by 33.8 kg per mu than the control group, with 7.01% yield increase rate.
