半旱浸润垄作是改善低温诱发型低产稻田的最有效措施。垄埂表面太阳辐射能增多,且分布不均,有效辐射提高,使近地面大气层与土壤之间的热能交换频繁;土壤热容量降低,导温率和导热率显著增大,热扩散加强,呈多向运动;土壤热代谢功能的增强,有助于水稻分蘖和千粒重、穗粒数的提高。 Semi-arid infiltration of ridge is the most effective measure to improve low-temperature-induced low yield paddy field. Ridge surface solar radiation increased, and the uneven distribution of effective radiation increased, near the surface of the atmosphere and soil heat exchange frequently; soil heat capacity decreases, the thermal conductivity and thermal conductivity increased significantly, the thermal diffusion strengthened, was more To exercise; soil metabolism enhanced function, contribute to rice tillers and 1000-grain weight, grain number increased.
