| 摘 要： | 在大田滴灌施肥条件下,对不同的滴灌施肥频率影响春小麦生长和产量的特点进行了试验研究。在春小麦全生育期施肥总量和灌溉制度相同的情况下,设置了3个施肥频率处理,分别为全生育期施4、7、10次肥,各处理之间的灌水定额和灌溉定额以及施肥总量都相同;观测了春小麦不同生育阶段的株高、分蘖数和叶面积指数;测量了春小麦的理论产量。试验...

| Abstract: | The field experiments were carried out under drip fertigation to study the effects of frequencies of fertilizer application on the spring wheat growth and yield.Under the conditions of the same total fertilizer and irrigation water regime,three frequencies of fertilization treatments(4 times,7 times,10 times) were set in the whole growth stage of spring wheat.The plant height,tiller number and leaf area index were observed in spring wheat growing stages,and the theoretical grain yield of spring wheat was me... |
