机播小麦不同施肥方式对产量影响的试验研究
Experimental Study of Different Fertilizing Method on Yield of Wheat
摘要
Abstract
In order to ascertain optimal fertilizing method of seed manure for wheat , field experiment is conducted .The two-level-three-factor orthogonal experiments are done .The influence of main factors such as relative position of fertilizers, relative depth of fertilizers and fertilizer amount on wheat production are studied .The test results show that , effect of fertilization depth on wheat production is greatest , relative position of fertilizers follows , and effect of fertilizer a-mount on wheat production is least .Orthogonal intuitive analysis shows that the best position to apply fertilizer is vertical deep position and the distance between fertilizers and seeds is 5 centimeters .According to test results , the impact of in-creasing fertilizer on yield is small relative to other factors .Meanwhile , the heavy use of fertilizers brings pollution . Therefore , it should be appropriate to reduce the amount of fertilizer applied .关键词
