摘要: 为研究“挖沟排水、施碱改酸、微肥调控、秸秆还田”的暖田技术对鄂东南冷浸稻田的改良效果,设置3个处理分别为常规技术模式(CK)、暖田技术模式(T1)、微肥改良技术模式(T2),明确T1和T2对冷浸田土壤温度和水稻产量构成的影响。结果表明,与CK相比,T1和T2对不同土壤深度的地温有增温的效果; T1和T2均能增加水稻分蘖数、有效穗、产量,T1的增产效果更佳; T1可提早水稻生育期,降低双季稻机插茬口衔接紧的风险。

Abstract: In order to study the improvement effect of the warm field technology of “ditching drainage, alkali application to acid, micro-fertilizer control, micro fertilizer regulation and straw returning” on the improvement of cold soaked rice fields in Southeast Hubei, three treatments were set up as conventional technology mode (CK),warm field technology model (T1) and micro-fertilizer improved technology mode (T2),to clarify the influence of T1 and T2 on the soil temperature and yield composition of cold soaked fields. The results showed that compared with CK, T1 and T2 had a warming effect on the ground temperature of different soil depths; T1 and T2 could increase tiller, effective panicle and rice yield, T1 had the better effect of increasing rice yield; T1 could advance the growth period of rice, reduce risk of tight stubble in double cropping rice machine.
