Abstract

Abstract: Whole-plant silage corn （Zea mays L.） is the main forage crop for the “grain to feed” policy. To screen out the optimal planting density of whole-plant silage maize suitable for popularization and application in Henan Province， the whole-plant silage maize variety ‘Qingyu 18’ was selected as the experimental material， and three treatment groups were set up， which were low density group （67 500 plants·hm^-2）， medium density group （75 000 plants·hm^-2） and high density group （82 500 plants·hm^-2）. The nutritional components and Cornell net carbohydrate-protein （CNCPS） components of each treatment group were determined， and the molecular structure was determined by Fourier transform infrared spectroscopy （FTIR）. The results showed that the crude protein （CP） content of silage maize in low density group was significantly higher than that of in medium density group and high density group （P<0.05）. The contents of neutral detergent fiber （NDF） and acid detergent fiber （ADF） in silage maize of high density group and medium density group were significantly higher than those of low density group （P<0.05）. There was no significant difference in the spectral parameters of protein and carbohydrate molecular structure among silage corn groups， but it was significantly correlated with some nutritional components （P<0.05）. Comprehensive analysis showed that the nutritional value and molecular structure of the whole plant silage maize variety ‘Qingyu 18’ were better under the planting condition of 67 500 plants·hm^-2， which was suitable for planting in Henan.

Key words: Planting density, Silage corn, Nutritional value, Molecular structure

摘要： 全株青贮玉米（Zea mays L.）是“粮改饲”政策的主要牧草作物。为筛选出适合河南地区推广应用的全株青贮玉米最佳种植密度，本研究选取全株青贮玉米品种‘青玉18’为试验材料，设置3个处理组，分别为低密度组（6.75万株·hm^-2）、中密度组（7.5万株·hm^-2）和高密度组（8.25万株·hm^-2），测定各处理组的营养成分和康奈尔净碳水化合物-蛋白质（Cornell net carbohydrate and protein system，CNCPS）组分，并结合傅里叶变换红外光谱（Fourier transform infrared spectroscopy，FTIR）技术对其分子结构进行测定。结果表明：低密度组青贮玉米粗蛋白（Crude protein，CP）含量显著高于中密度组和高密度组（P<0.05）；高密度组和中密度组青贮玉米中性洗涤纤维（Neutral detergent fiber，NDF）、酸性洗涤纤维（Acid detergent fiber，ADF）含量显著高于低密度组（P<0.05）。青贮玉米各组间蛋白质和碳水化合物分子结构光谱参数无显著差异，但与部分营养成分显著相关（P<0.05）。综合分析得出，6.75万株·hm^-2种植条件下，全株青贮玉米品种‘青玉18’ 营养价值及分子结构表现较好，适合在河南地区推广种植。
