The Research On Nutritional And Silage Value Of Intercropping Corn With Lablab Bean

Nutritional evaluation of6breeds of corn(corn stalk) and Intercropping Corn with Lablab Bean indifferent growing period,the purpose is to investigate the output of corn(corn stalk) and theIntercropping,nutritional value of corn and mixture silage and the former.Even more probe into therelationship between time and nutritional value of corn.The results show that:The value of6kinds of corn declined with the maturity time including CP, NDF,ADF and WSC.Asconcerned as corn stalk,the content of CP and WSC of all kinds corn declined with the growing time.Inopposition,the DM,NDF and ADF rised. Moreover,the difference among different breeds was obvious.Ingenerally, the difference among Feeding corn,Feeding and grain corn,and common grain corn was obviousin Nutritional evaluation.The changing regularity of intercropping corn with Lablab bean kept similar to corn lonely,but the Themixed sowing silage corn can significantly improve the contents of DM and CP (P<0.05) and decrease thecontents of NDF,ADF and WSC in the same time.The changing regularity of CP,WSC,NDF and ADF of silage of6whole corns and corn stalks keptsimilar to the content before silage.From the ferment parameter of silage and the nutritional evaluationdata,the effects of whole corn silage was better than the silage of corn stalk.The growing time worked onthe quality of silage, the quality of silage of last growing time corn was better than the earlier corn，but thequality of silage of earlier growing time corn stalks was better than the last corn. The silage quality ofGreen Feeding-corn excelled other breeds obviously, the silage quality of Feeding and grain corn excelledthe grain corn, at the same time，the silage quality of grain corn had intimate relationship to the harvestedtime.
