摘要：Taking the planning and designing of tourism orchard in Yanyang Farm of Taicang City as the study case,this paper aimed to shape this orchard into a natural,unique,cultural,participatory and sustainable modern tourism picking orchard,with the function of popularizing knowledge of flowers and fruits and displaying Hi-Tech *** on the introduction of superior new varieties of fruit trees,enhanced fruit production function,a sound basis for tourism picking orchard system will be *** designing plan divided the whole orchard into 4 parts,which are "Spring Garden","Summer Garden","Autumn Garden" and "Winter Garden".With landscape design of fruit trees as the key part,this paper made preliminary research on landscape design of this orchard.① "Spring Garden",which aimed to show early spring in the orchard of agricultural landscape,covering an area of 0.83 hm2,the main tree species were Malus spectabilis(Ait.) Borkh.,Cerasus pseudocerasus,Armeniaca vulgaris and Vatica mangachapoi.② "Autumn Garden",which aimed to show fruitful harvest scene,covering an area of 1.67 hm2,the main tree species were Punica granatum,Crataegus pinnatifida and Diospyros kaki Linn.f.③ "Summer Garden",which aimed to provide tourism attractions for students on summer vacation,covering an area of 1.73 hm2,the main tree species were peach,plum and Prunus simonii Carr..④"Winter Garden",which aimed to provide one activity area for tourists in winter orchard,covering an area of 0.96 hm2,the main tree species were Citrus reticulate Banco and Eriobotrya *** tourist orchard tried to achieve harmony unity of orchard fruit production,landscape tourism,recreational services and so on,thus providing useful references to the designing of tourist orchard in leisure agricultural farm.

摘要：The Qing Dynasty was the mature period of traditional Chinese gardens,and the construction of royal gardens reached its *** the method of image and text analysis,the landscape features of different seasons in the Chinese gardens were probed,the layout of its spatial elements and the method of plant landscaping was analyzed,and the artistic characteristics of the gardens in the Qing Dynasty was *** aesthetic conception of the gardens have been discussed from the following aspects,the integration of time and space,the harmonious relationship between the garden elements and the fusion of scenery and feelings.

摘要：With the development of the times, villa has already become one of the spiritual pursuits of people for higher living quality, and plants as a significant component of villa landscape construct the pleasant landscape environment together with hard landscapes within villa areas. Viewing at the villa landscape design, a villa could be divided into three functional areas, i.e. front yard, side yard and back yard, and the plant furnishing, planting goals as well as plant application were analyzed in this study, additionally, the significance of plants in creating landscape was stressed.

摘要：Trialing advanced candidates in tree fruit crops is expensive due to the long-term nature of the planting and labor-intensive evaluations required to make selection *** closely the trait evaluations approximate the true trait value needs balancing with the cost of the *** of field trials of advanced apple candidates in which reduced number of locations,the number of years and the number of harvests per year were modeled to investigate the effect on the cost and accuracy in an operational breeding *** aim was to find designs that would allow evaluation of the most additional candidates while sacrificing the least *** percentage difference,response to selection,and correlated response were used to examine changes in accuracy of trait *** the quality traits evaluated,accuracy and response to selection were not substantially reduced for most trial *** management influences the decision to change trial design,and some designs had greater risk associated with *** cost and accuracy with risk yields valuable insight into advanced breeding trial *** methods outlined in this analysis would be well suited to other horticultural crop breeding programs.
