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。
The effects of soil conditioner on the physicochemical properties of typical paddy soil and rice yield and its components in Hainan were studied. A completely randomized design was used to lay out paddy field plots. Application of soil conditioners increases soil pH, reduces soil bulk density, and increases porosity compared to treatment without soil conditioner. Soil conditioner can significantly increase the number of tillers and grains per spike, which is propitious to the increase of rice yield. Applying 600 kg of formula fertilizer per hectare and 375 kg of soil conditioner can increase yield and increase yield of rice. Soil conditioner can promote the development of soil in the direction of health, and the treatment effect of applying the largest amount of conditioner on the unit land is the best.
