运用土壤养分状况系统研究法(ASI)进行土壤测定和水稻肥料推荐,通过田间小区试验对滨海滩涂地水稻推荐磷、钾施用量进行验证。结果表明,在其它营养元素的施用量均在最佳推荐量条件下,ASI法测土推荐的磷(P2O5)、钾(K2O)最佳施用量(90 kg/hm2、105 kg/hm2)处理的水稻有效分蘖数、穗实粒数、千粒重及产量均是最佳的;且施磷能够显著增加水稻的有效分蘖数,施钾能够显著增加水稻穗粒数和千粒重,最终达到增产的目的。因此,运用ASI法对滨海滩涂地水稻进行测土推荐磷、钾肥的施用量是基本合理的。 Soil evaluation and rice manure recommendation were conducted based on the systematic study of soil nutrient status (ASI), and the recommended phosphorus and potassium fertilizers were tested by field plot experiments. The results showed that P2O5 and K2O optimum dosage (90 kg / hm2, 105 kg / hm2) recommended by ASI method under the best recommended amount were all applied in other nutrient elements. The effective tiller number, grain number per spike, 1000-grain weight and yield of rice were the best; and phosphorus application could significantly increase the effective tiller number of rice, and potassium application could significantly increase the number of grain per spike and 1000-grain weight, and finally achieve the purpose of increasing yield. Therefore, it is reasonable to use ASI method to soil recommended paddy rice in coastal beach.
