A Study on the Influences of Different Seedling Age of Cultivated Hybrid Late Rice 99 on Rice Output;

In order to investigate the effect of nitrogen level,seeding density and seedling age on seedling quality of rice,a two-factor experiment including four N levels(10.

Based on current rice production condition of Northeast China, in order to make farmers operating possibly, the cultivation technique s feasibility which transplant compressed or sparse or little seedling-age was researched.

The correlation between egg populations of the first generation of rice stem borer and leaf age of rice seedlings in rice nursery beds and its applications;
