| Walnut,versatile and with its seed of rich nutrition,is one of the 4 world's dry nuts and the important economic tree in China as well.lt has a long history and is wide spread .China's recent entry into WTO calls for rising amounts of walnuts in the market and higher quality and status According to the material analysis of its sales and the current circumstancds of the walnut industry both at home and abroad, the paper advocates the establiching of fine walnut orchard for high yield and efficiency through accomplishing green fine seeds management based on the walnuts grown in the mountain areas in Yichang.Makrng full use of statistics,analytic chemistry,ecology,biology and cultivating principles,this paper begins with individual selection of improved varieties of walnut improving the survival rate in grafting and breeding and meets the needs of large numbers of fine walnut trees in the ecological walnut orchard construction and solves the matching techniques of walnut's non-harrnness high yield planting and the walnut's fruit products production.The key to the cultivation of fine trees in quantity is to find out the best time and way to graft and breed. The technologies of cultivation withoutharmness focus onrselecting the place without the three industrial wastes which has good environment and is far away from cities, factories and mines to build the orchard, making the most of good ecological environment to be composite management of orchard,scattering more organic manure and persisting in twice covering and laying plant each year, trimming at proper times and keeping blossom and fruit scientificalry^ioticing synthetic and agricultural treatment of pest, forbidding chemical pesticide abuse and so forth , So that high production,good quali1y,and highly productive efficiency of walnuts in the mountain areas in Yi Chang come true and therefore,a new way has been found out which will adjust ecology and econogy and bring about sustainable development for the mountain areas. |
