肉鸡养殖对枇杷品质影响及效益分析

Effect on fruit quality and economic evaluation of raising broilers in loquat orchard

在枇杷园内套种圆叶决明并放养肉鸡,以室内圈养为对照,结果表明:(1)果园放养日均增重为55.5g,室内圈养的日均增重58.5g,80d后果园放养的重量为2.965kg,圈养的肉鸡重量为3.125kg,放养的肉鸡品质优、售价高,放养比圈养收益增加95.04%;(2)套种圆叶决明且2年均在果园内放养肉鸡的果园土壤全氮含量达到2.217g.kg-1,果园进行肉鸡放养在治理虫害的同时,以鸡治草降低了人工除草用工,而鸡粪回田又提高了果园土壤肥力;(3)果园套种圆叶决明并放养肉鸡与自然生草相比,枇杷单果重、固形物含量分别提高13.68%、12.25%。

Using broilers raised indoor as control to compare with those in a loquat orchard that was intercropped with Chamaecrista routundifolia,a trial was conducted to evaluate the effects of such practice.The result showed that：（1） The broiler＇s average daily weight gain was 55.5 g for the orchard-raised group and 58.5 g for the control.After 80 days,the average broiler weight was 2.965 kg for the treatment group,and 3.125 kg for the control.However,the orchard-raised broilers were of more desirable quality demanding a higher market price than those from the control group.The net income increased by 95.04%,as a result.（2） By intercropping C.routundifolia while raising broilers for two consecutive years,the orchard had a total N of 2.217 g·kg^-1 soil.The practice also reduced pest population,improved weed-control saving on weeding labor,and enhanced soil fertility for the orchard.And,（3） The single fruit weight and soluble solid content of the loquat fruits harvested from the trees in the treatment orchard increased by 13.68% and 12.25%,respectively,in comparison to those from a conventional orchard.
