摘要
Abstract
An experiment was carried out to study the effect of nitrogen application on the growth and yield of strong gluten wheat variety ‘Yannong 19’during 2015 in Jiangsu,Yuntai farm.Five treatments were arranged in the test:fine with ni-trogen,nitrogen,school,routine,no fertilizer treatment (CK).The results showed that the number of wheat seedlings of re-fined nitrogen treatment was the highest,and the seedlings number at mature stage increased the most,which was 19.37%higher than that of the conventional treatment.Compared with the conventional treatment,the effective panicle number, grain number per spike,grain weight and grain yield of the refined nitrogen treatment were increased.Therefore,the suit-able nitrogen level was 701.4 kg/hm2 (46% urea),and the ratio of base fertilizer,tillering fertilizer and jointing booting stage fertilizer =1∶1∶2 treatment showed the best effect.关键词
