Abstract:

In order to ease the leguminous forage shortage with the development of stock raising in Fujian Province and provide the basis for the use of reasonable, the situation of peanut straw resources of Fujian Province should be researched. Yield and major quality of straw and carbon fixation of 12 peanut varieties suitable for cultivation in Fujian Province were evaluated, by adopting the randomized block experiment and quality analysis methods, combined with the data of statistical yearbook. The results showed that, the pod yield of 4012.5-5557.5 kg/hm2, for an average of 5119.5 kg/hm2; seed yield of 2742-3843 kg/hm2, an average of 2881.5 kg/hm2; peanut straw fresh yield of 20425.5-28488 kg/hm2, for an average of 24475.5 kg/hm2; peanut straw moisture content 69.95%-73.98%, for an average of 72.41%. 2008-2010 Fujian Province peanut straw fresh yield estimation was 2350870-2424530.3 t, year average of 2391990 t; hay weight of about 648600-668900 t, year average of 659950 t; straw protein content of 8.38%-10.7%, for an average of 9.57%; crude fat content of 1.2%-2.5%, for an average of 1.7%; the total sugar content of 0.82%-6.26%, for an average of 4.72%; sucrose content of 0.4%-3%, for an average of 2.2%; reducing sugar content of 0.4%-3.2%, for an average of 2.4%; neutral detergent fiber content 43.03%-52.4%, for an average of 46.48%; acid detergent fiber content of 33.49%-42.23%，an average of 36.67%; pickling lignin content of 7.19%-9.66%, for an average of 8.15%. 2008-2010 Fujian Province peanut straw fresh yield estimation was 2350870-2424530.3 t, year average of 2391990t; hay weight of about 648600-668900t , year average of 659950 t. Comprehensive analysis, Fuhua 4, Wanhua 4 straw quality were better. Peanut fixed CO2 about 133.455924-143.007561 t, year average of 136.0317315 t in Fujian Province. Peanut straw was quality pasture resources, equivalent to 650000 t of feed grain. peanut production on CO2 fixed contribution was enormous and reduced the CO2 emissions on atmospheric greenhouse effect.
