%X A plot experiment with different N rates(135 kg/hm2 and 105 kg/ hm2) was designed to study the effects of panicle N fertilizer ratio on absorbability of rice root in cold area.The results showed that the root bleeding and soluble sugar content of root in the 15% panicle N under high N level(135 kg/ hm2) was lower and in the treatment of 35% under middle N level(105 kg/ hm2) was higher at each period.Under the same N level,compared with 15% panicle fertilizer,the root bleeding of 35% panicle fertilizer were ...
