摘要
在油菜、大麦茬上,利用接茬问隙,以简易的湿润育秧法,培育适龄、整齐、健壮的小苗;据最适LAI、高产株型及单株成穗等要素确定群体最适起点;以平衡施N模式配合水湿灌溉模式。在稻苗早发条件下提前抑制无效生长。平衡扩大中期个体生长量。改善生育中、后期群体质量,由这三方面为主体构成了麦茬小苗稻高产节本的栽培技术新体系。
The young seedlings, characterized by suitable age, uniformity and vigour, were cultured by means of the simple wet-raising seedlings in the field following the barley (or rape) during the period from the harvest of barley to rice transplant; The population beginning density was determined on the basis of the optimum LAI, the high yield plant type, the number of ear per plant and so on; The population quality was improved in the middle and late period, which was achieved by means of balancing the model of the nitrogen fertilizer application fitting in with the model of the irrigation that kept shallow water in the early period, dry and wet alternately in the middle and late period. The two modles might inhibit earlier unavailable growth on condition that the seedlings growed luxuriantly in the early-period, then enlarge growth increment of individual in the middle period. The above three main respects constituted the new system of the high yield and low cost cultivation technique of the young seedling rice.
