收刈时间对玉米秸秆营养物质产量的影响

摘要/Abstract

摘要： 【目的】从玉米植株秸秆的总可消化养分产量考虑，确定植株的适宜收刈时间可有效利用秸秆饲料资源，【方法】为此本试验大田试验种植4个早中熟玉米品种，包括农大108、高油298、冀丰58、郑单958，在生长期的92d、96d、100d和104d收刈秸秆，研究收刈时间对秸秆营养物质产量的影响，【结果】试验结果表明，收刈时间明显影响玉米秸秆的有机物、蛋白质、纤维性物质和可消化有机物产量，【结论】所选种的玉米品种秸秆蛋白质和可消化有机物产量在100d达到峰值

Abstract: 【Objective】Four different maize cultivars, nongda108, gaoyou115, jifeng58, zhengdan958, were chosen to study the effects of different harvested time on the yield of nutrient substance of corn stalk.【Method】The corn stalk were harvested at the growth days of the 92nd ,96th ,100th and 104th, respectively.【Results】The results indicated that there were obvious effects on the yield of organ matter, crude protein, fiber substance and digestible organ matter by different harvested time and different maize cultivars.【Conclusion】The results of trials indicate that the corn stalk could be harvested at the growth days of the 100th.
