Abstract
[Objective] To study the effects of different seed fertilizer spacing (horizontal distance of seed fertilizer and fertilization depth) on
summer maize yield, so as to provide technical support for light, simple, high yield and efficient cultivation of summer maize.[Method] Frac-
ture zone design was horizontal distance of various fertilizers (5,10,15,20 cm) was mainly treated; four fertilization depths (4,
8,12,16 cm) were treated as side treatments.[Result] The different seed manure spacing (seed manure horizontal distance and fertilization
depth) on summer corn seedling emergence, root morphology and yield factor, production had a significant effect, both interactions had a sig-
nificant positive effect, have maintained good germination rate, root morphology and get better production factor, thus increasing production.
The yield of summer maize increased at first and
