The Effects of Nutritious Conditions of Seedlings on Growth of Transplanted Tobacco (II)

[摘要] Tobacco seedlings were grown under various combined conditions of different nitrogenous fertilizers and spraying of sucrose solution to obtain the seedlings containing various levels of nitrogen and sugars. Then these seedlings of each plot were transplnated to the field under the conditions of standard nitrogenous and non-nitrogenous fertilizers, and studied on the relations of their nutritious conditions in the seed-bed period and growth after transplanting. As the results, it was recognized that the amounts of nitrogen maintained in the seedlings correlated significantly with absorption of nitrogen and growth on the field after transplanting through a function as a starter. Consequently, to obtain such a good seedling that shows good appearance in growth after transplanting, it was suggested that the supply of nitrogenous fertilizer to the seedlings in the seed-bed period should be considered and also existence of sufficient soluble nitrogen in the field available to seedlings at the time of transplanting should be assured.
