The purpose of this experiment is trying to find out the best economical hybridized combination of partridge sichuan ducks, which would grow faster, have heavier body weight and higher meat production as well as be fit for running in the paddy fields. The results showed that jian-chuan hybrid had a number of favourable attributes over Jing-Chuan and Di-Chuan hybrids. The former reached 1. 5kg of market body weight about 15 days earlier than the control group of partridge sichuan duck nomadizing in the paddy...

The purpose of this experiment is trying to find out the best economical hybridized combination of partridge sichuan ducks, which would grow faster, have heavier body weight and higher meat production as well as be fit for running in the paddy fields. The results showed that jian-chuan hybrid had a number of favourable attributes over Jing-Chuan and Di-Chuan hybrids. The former reached 1. 5kg of market body weight about 15 days earlier than the control group of partridge sichuan duck nomadizing in the paddy fields under the same conditions. The muscle weight of breast and thigh of Jian-Chuan hybrid ducks at 60 days of age was20% heavier than that of partridge sichuan ducks. Jian-chuan, therfore, is an ideal combination for developing duck industry in Sichuan Province.

本试验的目的在于试图筛选出生长快、体重较大、产肉量较高并适于稻田放牧的四川麻鸭经济杂交组合。试验结果表明,建川杂交鸭比京川和狄川杂交鸭具有许多有利的特质。在相同的放牧条件下,建川杂交鸭比四川麻鸭提早15天达到1.5公斤的上市体重,胸鸭肌重比四川麻鸭高出20%以上。这是适于我省发展稻田养鸭业,与水稻收获季节紧密配合,节约用粮,短期内可提供优质肉用仔鸭上市的一个比较理想的经济杂交组合。1984年已在名山县推广20余万只。

Partridge Sichuan(S)ducks were crossed with Jianchang (J), Peking(P) and Tegel (T) drakes, with the purebreds intermated as control groups. The Body weights(B.W.) of 368 ducklings in all of the breeds and crossbreds were recorded from day-old to 60 and 70 days of age in every 10 days under the condition of nomadizing in paddy fields, and then slaughtered for carcass analysis.The B.W.of J×S, P×S and T×S were 1458.0, 1500.0 and 1436.0 g at 60 days of age, and 1638.5, 1792.05 and 1648.0 g at 70 days of...

J×S and P X S were heavier than their parents.The heterosis for the B.W. were generally positive and statistically significant. The weights of carcass, breast muscl and thigh muscle were higher for crosses than for their parents and significant heterosis was observed for the former two traits at 60 days of of age. The contents of Lysine and Methionine in the breast plus thigh muscle were the highest for J×S, and Tegel ducks were the fattest in the breeds and crossbreds.

用四川麻鸭母鸭与建昌鸭、北京鸭和狄高鸭公鸭杂交,纯种设平行的对照。在放牧为主、人工给饲为辅的条件下每隔10日龄测定鸭群至70日龄的体重,并于60和70日龄分别屠宰一半,进行屠体分析。建川、京川和狄川鸭60日龄体重分别为1458.0、1500.0和1436.0克,70日龄分别为1638.5、1792.5和1648.0克,均显著高于四川麻鸭(p<.05)建川和京川还具超双亲表现。自出壳至70日龄体重的杂种优势一般较高而显著。60日龄建川、京川和狄川鸭屠体重(分别为884.0、887.0和882.5克),胸肌重(分别为59.2、49.7和50.5克)和腿肌重(分别为142.4、140.2和136.6克)均超过各自的双亲,屠宰性状的杂种优势,建川和狄川70日龄比60日龄明显下降,而京川则有上升之势。建川鸭胸腿肌赖氨酸和蛋氨酸含量居参试品种和杂种之首,屠体脂肪含量以狄高鸭最高。试验还观察到三个优良肉用品种在放牧为主的条件下不能发挥其快速生长潜力。据此,在四川稻田养鸭条件下推广这三个杂种,可获较大的经济效益。

A field experiment was conducted to deal with the characteristics of integrated agroecosystems in Three Gorges Reservoir Area in upper region of Yangtze River. Based on ecological principle and intercropping technology, several integrated agroecosystems such as wheat - malie-sweatpotato, wheat-vegetable, citrus intercropped with wheat and different rice rotation systems weredeveloped in this region. The experimental results revealed that the output and economic benefitof wheat intercropped with vegetable were increased by 40% - 47% compared to the normalwheatrmaize-sweat potato cropping system in upland soils. The rice yield in single riceduck-fish system reached at 9 540 kg/hm2, 12. 5 % higher than rice alone system. The economic ratio of output/input was 3. 92 in rice-fish system, 3. 81 in rice-duck-fish system and 4. 72in rice-straw berry system, respectively, which was 50% higher than the rice alone system.Additionally, the harmful effects infected by injurious insects were retarded at great extent inrice-fish or rice-duck system and the harmful weed in rice field was reduced, so that the pestifcide and herbicide application could be reduced in these systems. By practising rice-duck orrice-duck-fish system for several years the soil properties were improved, especially the organicmatter and total nitrogen content, available nitrogen and phosphorous in rice field were increasedsignificantly. Therefore, to develop different lute.rcropping systems in upland and different riceoriented rotation systems in rice field can increase the crop yields and get a high economic benefit,so that the Income of local farmers can be increased at some extent.

通过田间试验研究了长江三峡库区主要的复合农业生态系统类型及其特点。应用生态学原理和间套作技术,在三峡地区建立了“小麦一玉米一红薯、小麦一蔬菜、柑桔一小麦、稻田复合系统”等多种复合农业生态系统。田间试验结果表明,旱地采用“小麦一蔬菜”方式比传统的“小麦一玉米一红薯”方式提高经济效益40%~47%,“中稻鸭鱼”模式的水稻产量达到T9540kg/hm2,比对照提高12.5%。中稻一鱼、中稻一鸭鱼、中稻一草荡的经济产投比分别为3.92,3.81,和472,比传统模式提高50%以上。此外,稻田养鸭或鱼系统可减少稻田害虫为害率,减少稻田杂草的发生率,减少农药的使用次数。通过几年的试验,养鸭、养鱼稻田的土壤性质也发生了一定的变化,土壤有机质、全氮、有效氮、有效磷等明显增加。因此,在三峡地区的旱地和稻田建立不同的复合农业生态系统既可提高作物的产量,也能获得较高的经济效益,从而增加农民的经济收入。
