Effecf of dietary supplementation of various levels of chloric anion and bicarbonic anion on serum anion compositions,laying rate,feed conversion efficiency and eggshell quality of hens was studied. The results showed when supplementary amount of chloric anion and bicarbonic anion in the diet was 0. 121%.(total amount of chloric anion in the diet was 0.212%)and 0. 145% (total amount of bicarbonic anion in the diet was 0.276%),respectively the concentration and ratio of equivalent weight of anion in serum of...

【Objective】An experiment was carried out to investigate the effects of relay intercropping of spring-sown maize and summer-sown maize on dry matter yield and nutritive values of whole-crop forage at different nitrogen level compared with sole cropping.【Method】The effects of relay intercropping at different nitrogen levels on dry matter yield,crude protein yields and crude fat yields of the spring-sown maize,summer-sown maize,and the whole year were studied in a randomized block design.And the reasons of these effects were analyzed from the changes of nitrogen uptake and field microclimate.【Result】Relay intercrops were higher in the annual yields of dry matter,crude protein,and crude fat than either spring-sown maize or summer-sown maize grown as sole crops.The land equivalent ratios of crude protein yield of whole-crop for N1(187.5 kg.ha-1) and N2(375 kg.ha-1) were 1.54 and 1.77,respectively.And the land equivalent ratios of crude fat yield of whole-crop for N1 and N2 were 1.39 and 2.55,respectively.In general,the dry matter yield and nutritive values of relay intercrops were lower than those of sole crops.But at N2,the crude fat yield of spring-sown maize in relay intercropping system was higher than that of sole cropping;and no significant differences were observed between the crude protein yield of summer-sown maize relay intercropping and that of sole cropping.The nitrogen uptake of relay intercrops were lower than that of sole crops,but increased with nitrogen applied more quickly.【Conclusion】Compared with sole cropping,relay intercropping of spring-sown maize and summer-sown maize can increase the annual nutritive values,which are mainly resulted from nitrogen uptake and field microclimate.In the relay intercropping system,the nutritive values of spring-sown maize are affected greater,while those of summer-sown maize are affected less,because of their different growth stages in coexistence.Increased the application of nitrogen can relax the competition in relay intercropping system,and improve the yield and nutritive values of whole-crop forage.

【目的】以单作为对照,研究不同施氮水平下春夏玉米套作对全年饲用营养价值的影响。【方法】采用随机区组设计,研究不同施氮水平下套作体系中春玉米、夏玉米及全年生物产量、粗蛋白产量和粗脂肪产量与单作的差异,并从氮素吸收利用、气候因素等方面分析造成差异的原因。【结果】套作显著提高了全年的生物产量和营养价值。套作体系N1(187.5 kg.ha-1)和N2(375 kg.ha-1)条件下的全株粗蛋白产量的土地当量比分别为1.54和1.77,全株粗脂肪产量的土地当量比分别为1.39和2.55。套作条件下,单季作物的生物产量和营养价值一般比单作低。但在N2条件下,春玉米全株粗脂肪产量高于单作,夏玉米全株粗蛋白产量与单作差异不显著。套作体系全年吸氮量显著低于单作,但随着施氮量的增加其吸氮量增幅高于单作。【结论】与单作相比,春夏玉米套作体系利于全年营养价值的提高。这种效应是氮素营养状况及气候因素状况等共同作用的结果。在套作体系中,春玉米营养价值受竞争影响较大,而夏玉米受竞争影响较小,这与竞争发生时作物所处的时期不同有关。合理增施氮肥可以缓解复合群体的竞争而使营养价值显著提高。
