【摘要】 利用三膜覆盖，减少昼夜温差，防御早霜危害，进行早期水稻育苗，并通过精量播种，压沟条播，培育苗高１６ｃｍ，百株干重达８．５ｇ以上带多蘖大苗。本田采用超稀植栽培，消除当前生产中因密植所产生的各种生理障碍，协调个体与群体生育矛盾，充分发挥个体增产潜力，叶片数增加１～２个，且利用低位分蘖，延长分蘖时间，达到高产所需穗数，活秆成熟。试验提出早熟品种合江１９获８２５０～９０００ｋｇ／ｈｍ２的超稀植栽培技术措施，为今后水稻高产再高产提供理论与实践依据。更多还原

【Abstract】 Early nursery of rice seedlings with threelayer covering and sowing in line through ditching could reduce the odds of the temperature between day and night and defend early forst , obtaining big seedlings with more tillers, 16cm high, 8.5 gramme of dry weight per 100 seedlings in cold region. Adopting super thin planting in paddy field could eliminate some physiological hindrance, harmonize the relation between individual plants and the population,make the best of highyield potentiality of individuals, increase 1-2 leaves, utilize the tillers at lower nodes,prolong the time of tillering, achieve the stems that highyield needs and keep stems green when corns maturated. In this experiment the super thin planting technology for Hejiang 19 achieving 8 010-9 120kg/ha was showed, and provided the evidence of theory and practice for higher and higher yield in future.更多还原
