Analysis Of The Effects Of Two Tree Species On The Cultivation Of Physiological Indicators And Economic Traits Of Juglans Regia ‘Xin Wen 185'

In this study,the first division of the three groups of 6 year old Juglans regia ‘xin wen 185' as materials,studied two kinds of tree canopy structure characteristics,canopy micro environment(light,temperature,humidity),differences in the effects of inner leaf photosynthetic characteristics and fruit yield and quality,the trunk results are as follows:(1)the trunk tree tree high,crown canopy,row spacing,mechanized management,suitable for planting.Natural globeshaped crown is low,the crown,the canopy line spacing is small,is not conducive to mechanized operation,the planting density should not be too dense.The trunk form of short branch proportion is as high as 54.83%,the low proportion of vegetative branches per plant,less total number of branches,branches per unit area.The natural round shape short branch proportion is 35.96%,a high proportion of vegetative branches per plant,branches,total branches per unit area and less quantity of branches.The chlorophyll content and the weight of the trunk blade were better than that of the natural round shape.(2)two kinds of tree canopy light intensity from bottom to top,from the inside to the outside gradually increased,the main tree canopy light distribution,different parts of the light intensity difference is small,the natural round shape,inner and peripheral,lower intensity differences and Kobe Hikaruteru.The light intensity of the main middle,lower and middle,inner bore is significantly larger than that of the natural round head.The proportion of invalid area in the trunk shape is small,and the proportion of the natural void area is large,and the proportion of the dominant area of the trunk is large,while the natural circular shape is small.The relative light intensity distribution in different parts of the main canopy is relatively uniform,while the distribution of the natural round head is uneven.(3)the diurnal variation of temperature in different parts of the trunk and the natural shape of the round head of the two tree canopy showed a "S"-shaped curve of decreasing-increasing-decreasing,the canopy from the bottom up,from the inside to outside the temperature gradually increased.The lowest temperature in the morning 6:00,the highest temperature at 14 noon.From8:00-20:00 this time,in the vertical direction of the canopy,trunk shape and natural round shape of middle and upper temperature difference is not significant,lower temperature difference,the main shape of 3.6 DEG C higher than natural round in the horizontal direction,the canopy,trunk shape and natural round shape,central peripheral temperature difference is not significant,bore significant difference the main shape,3.2 ? higher than natural round.The temperature difference between day and night in the main canopy is larger than that of the natural round shaped day and night,which is more conducive to the accumulation of dry matter.From May to June in June after the temperature rise,the temperature gradually decreased,the main canopy shape between the different parts of big changes in temperature,monthly mean temperature difference is small,the natural round shape between the different parts of the canopy temperature difference.(4)the main shape and natural round shape of two different parts of the canopy relative humidity,diurnal variation showed a decrease increase decrease of the "S" curve,canopy from bottom to top,from the inside to the outside relative humidity decreased gradually.During the day,the relative humidity is low,the relative humidity is high at night,and the relative humidity in the morning 8:00 is the biggest,and the humidity is the lowest at 18:00 p.m..The relative humidity ofthe trunk and inner chamber is significantly smaller than that of the natural round head.The relative humidity in June was the lowest and the highest relative humidity in September.(5)the diurnal variation of net photosynthetic rate,stomatal conductance and transpiration rate showed the Shuangfeng curve,and the maximum values were obtained at 12:00 noon.The diurnal variation of net photosynthetic rate,stomatal conductance and transpiration rate of natural head shape showed a single peak curve,and reached the maximum value at 14:00 noon.The main form of net photosynthetic rate,stomatal conductance,transpiration rate,intercellular CO2 was higher than natural round shape,the main tree leaves illustrate the ability of photosynthesis is greater than natural round shape,the accumulation of photosynthetic products than the natural round shape of tree,the utilization rate of light is higher than the natural round shape,is conducive to the appearance of the fruit quality and quality.(6)were the trunk form and natural round shape per plant fruit number was 66.2 and 191.1 in the vertical direction,the canopy trunk Guaguo concentrated in the lower level accounted for78.7%,natural round shape concentrated in the upper 88.2%.In the horizontal direction of trunk canopy shaped fruiting concentrated in the central and inner accounted for 79.4%,natural round shape Guaguo concentrated in the peripheral and central 90%.Acres of tree trunk for 133.2 strains,33.3 strains of natural round shape,the trunk form of 8817.84 acres of water,natural round shape6363.63,trunk shape than natural round shape with 2454.21 acres of fruit.The external quality and inner quality of the trunk fruit were better than that of the natural round shape.(7)the main shape of the average fruit weight is 15.20 g,the natural round shape 14.30 g trunk shape than natural round shape weight 0.90 g;the average trunk seed weight was 10.70 g,the natural round shape 9.17 g trunk shape than natural round shape with 1.53 g average kernel;kernel rate average trunk 69.95%,the natural round shape 64.75%,trunk shape than natural round shape 5.2%;the content of crude fat is 67.10% trunk shape,natural round shape 66.66%,trunk shape than natural round shape 0.44%;the content of total sugar backbone is 10.59%,the natural round shape 10.19,trunk shape than natural round shape 0.41%;the main form of the total protein content was 17.32%,the natural round shape 16.57%,trunk shape than natural round shape 0.76%.Per unit area(666m2)yield of 134 kg,the natural shape of the round head is about 91 kg,trunk shape is higher than the natural round head of 43 kg.(8)the manual input on trunk pruning,fertilization sprayingpesticide,harvesting farming operation costs 4100 to 5500 yuan,the natural round shape need to spend 5000 to 6400 yuan,the main shape than natural round shape cost 900 ~ 2100 yuan.1 hm2 trunk total revenue of $40209,profit of $34709 to $36109,the natural round shape of the total revenue of $27300,profit of$20900 to $22300.The main form of profit higher than the natural round head 13809 to $15209,per unit area(666m2)profit of 920.6 to $1013.9.
