| This test by Shenbao No.3 as the experimental material, compared with conventional planting, set the partial ridge-narrow/wide row,2-0 culture and two row of big ridge three uneven planting patterns, through to Shenbao3yield and yield components, morphology, physiology, field microclimate, quality and other indicators studied Shenbao No.3 growth and development of different planting patterns on yield and quality, in order to popcorn high-yield, high-quality production to provide reference. This research mainly results were as follows:1. Three uneven planting increased yield of Shenbao No.3 grain, improved the indicators related to production. The partial ridge-narrow/wide row planting methods yield the highest, 4820.94kg/hm2, than conventional planting methods improve 7.23%, and 2-0 culture and two row of big ridge also increased 4.44% and 3.37% than conventional plant way on yield; the partial ridge-narrow/wide row and 2-0 culture planting way’ ear row number, row grain number and grain weight were compared with conventional cultivation reached a significant difference. Double spike rate of three uneven planting modes were significantly higher than conventionally mode; lodging and empty ratio were decreased. The biological yield perform-ance for partial ridge-narrow/wide row>2-0 culture>two row of big ridge>conventional planting.2. The partial ridge-narrow/wide row,2-0 culture, two row of big ridge compared with common planting height reduced, increasing the stem diameter, leaf area index increased, lower ear and ear’ leaf orientation value decreased, root traits have improved to some extent. The partial ridge-narrow/wide row,2-0 culture, two row of big ridge than conventionally grown plant height than the 2cm～10cm; stem diameter increased by 0.07cm-0.27cm; leaf area index heading unevenness of three cropping patterns than conventionally grown increased 6.23%-8.31%. Lower ear and ear’ leaf orientation value than conventionally grown from 0.15% to 1.09% and from 0.01% to 2.93%. Uneven plantings’ total root length, root diameter, root volume, total root weight compared with common planting have increased in varying degrees.3. Three uneven planting patterns improved the photosynthesis related indicators, chloro- phyll SPAD number, photosynthesis rate, photosynthesis rate, leaf inter cellular CO2 concentration and leaf transpiration rate were higher than conventional planting. Three kinds of uneven planting ways in the whole growth period of SPAD number was higher than conventionally planting 0.51%～9.44%. The number of photosynthesis rate was 0.83% to 35.70% higher than conventional planting. Three kinds of uneven planting mode of photosynthesis rate, photosynthesis rate, leaf inter cellular CO2 concentration and leaf transpiration rate compared with common planting have varying degrees of increased, the partial ridge-narrow/wide row was optimal performance.4. Three uneven planting ways to optimize the field microclimate environment within the group. Three uneven planting ways compared with common planting has increased in light permeating rate, at 0.5m under the ear, the ear and the ear on 0.5m compared to conventional planting improved 12.98%～141.22%,7.10%～180.35% and 1.71%～70.35%. Among them, 2-0 culture was the most improved. Three uneven planting ways’wind speed in a row were less than conventionally grown, there were significantly higher than conventional cultivation in row middle. There field average CO2 concentration than conventional planting were increased 0.57%～1.36%. The temperature in the field of 2-0 culture was highest, the partial ridge-narrow/wide row was second. The partial ridge-narrow/wide row planting way’air humidity is the lowest in each level field, and normal planting was the highest,2-0 culture and two row of big ridge were double-between.5. The Shenbao No.3’three kinds of uneven planting pattern of each kernel, but the difference was not significant. Different planting methods for Shenbao No.3 grain’fat, protein and starch content had little effect. |
