摘　　要：[目的]寻找适合河北滨海区的腐熟剂以及合理的栽培措施。[方法]通过田间试验开展了3种腐熟剂、非栽培期水分管理及移栽时期对水稻分蘖及生长的影响研究。[结果]与其他处理相比,施用低温复合菌系HT20处理提高水稻分蘖效果最显著;非栽培期灌水处理会提高水稻的分蘖;早植对于水稻分蘖有一定的好处但最终影响不大,晚植不利于水稻分蘖;常规移栽更利于水稻生长。[结论]水稻秸秆还田中应用低温复合菌系HT20,并实施非栽培期适当灌水和5月中下旬移栽能够减少秸秆腐解产生的危害,促进水稻分蘖和生长。[Objective]To search for suitable decomposing agent and reasonable cultivation measures in Hebei coastal area.[Method]The effects of three decomposing agents,water management in non-cultivation period and transplanting period on rice tillering and growth were studied through field experiments.[Result]Compared with other treatments,the application of low-temperature compound strain HT20 had the most significant effect on improving rice tillering;irrigation treatment during non-cultivation period could increase rice tillering;early planting had certain benefits for rice tillering,but the final effect was not significant,late planting was not conducive to rice tillering;conventional transplanting was more conducive to rice growth.[Conclusion]The application of low-temperature compound strain HT20 in rice straw returning to the field,proper irrigation during non-cultivation period and transplanting in mid late May could reduce the damage caused by straw decomposition and promote rice tillering and growth.
