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。
The use of three-membrane coverage, reduce the temperature difference between day and night, early frost damage prevention, early rice seedling, and by precision sowing, gutter sowing, cultivating seedling height 16cm, dry weight of more than 8.5g with more tiller seedlings. Honda adopts ultra-thin planting to eliminate various physiological obstacles caused by close planting in the current production, to coordinate the contradiction between individual and group reproduction, and to give full play to individual potential for increasing yield. The number of leaves is increased by 1 or 2, and tillers are lengthened with low tillers , The number of ears needed to reach high yield, mature live straw. The experiment put forward that the early maturing variety Hejiang 19 obtained 8250 ~ 9000kg / hm2 ultra-rare-earth cultivation techniques and provided the theoretical and practical basis for the future high yield and high yield of rice.
