【摘要】 研究土壤调理剂的施用对海南典型水稻土理化性状和水稻产量及其构成因素的影响。采用完全随机设计方案布置了水稻田间小区试验。与不施用土壤调理剂处理相比,施用土壤调理剂可提高土壤pH值、降低土壤容重、增加孔隙度。土壤调理剂可明显提高水稻分蘖数和每穗粒数,有利于水稻产量的提高,以每公顷施用600 kg配方肥和375 kg土壤调理剂处理水稻增产、增收效果明显。土壤调理剂能促进土壤往健康的方向发展,单位土地上施用最大量调理剂的处理改良效果最佳。更多还原

【Abstract】 To study the effect of physicochemical properties and form factor of rice yield by using soil conditioner on paddy soil in Hainan,using the completely random design to make arrangement of the rice field plot experiment. Compared with no soil conditioner processing, the used could increase soil pH value and soil porosity, reduce soil bulk density. It also could improve the grains per spike and tiller number significantly. The most obvious effect of increasing yield of rice was using 600 kg fertilizer and 375 kg soil conditioner per hectare. Soil conditioner could promote soil health, and the aplication of most soil conditioner made the most optimal improvement effect.更多还原
