栽培模式和复合肥类型对隆平206农艺性状及干物质积累的影响
Effects of cultivation patterns and compound fertilizer types on agronomic traits and dry matter accumulation of Longping 206
摘要
Abstract
We studied the effects of four cultivation patterns and two compound fertilizer types on the root morphology index at seedling stage, the volume and the dry weight of root at elongation stage, the physiological property of root, leaf and stem, the agronomic traits and dry matter accumulation, grain filling and N, P and K accumulation, photosynthetic characteristics and yield components.This experiment was done at the science and technology garden in Anhui Science and Technology University and designed by two-factor split block design.The main plot was row-spacing allocation and double plants a hole.The four seeding styles were equal row spacing (A1, 60 cm), equal row spacing and double plants a hole (A2, 60 cm), wide and narrow row spacing (A3, 70 cm+50 cm), wide and narrow row spacing (A4, 90 cm+30 cm), respectively.The vice plot was base fertilizer type and used Stanley compound fertilizer and Difuyuan special compound fertilizer for corn.The experiment had eight treatment groups and four repetitions for each group.The seeding density was 67 500 cobs·hm-1, the width of each plot was 3 m, and the length was 6.67 m.The underground fertilization amount was 750 kg·hm-1.The plant height and growth rate of Longping 206 had not significant difference between equal row spacing and wide and narrow row spacing, but had significant difference during the pattern of equal row spacing with double plants a hole.The ear height had not significant difference between A1 and A3, while had significant difference between A4 and A2.The stem diameter had not significant difference between each treatment.The effects of cultivation patterns on the angle between first leaf of above ear and first leaf of under ear had significant difference, and on the first leaf orientation value of above ear also had significant difference, but on the first leaf orientation value of under ear had not significant difference.The effects of cultivation patterns on the stem intensity of ear knob and upper ear knob and on the dry matter accumulation at different stages had significant difference.Longping 206 in wide narrow row spacing (90+30) cm, Difuyuan special compound fertilizer, the indexes of agronomic characters of long reached the best state, the effects of cultivation pattern of dry matter accumulation of significant difference of Longping 206 on different periods, at jointing stage, booting, flowering stage, milk stage and mature period, the amount of dry matter accumulation of Longping 206 were the biggest in cultivation mode row(70+50) cm.It illustrated that different cultivation patterns and compound fertilizer types made important effects on the growth of Longping 206 and provided some information for cultivation management and fertilization of Longping 206.关键词
