| The labor-saving cultivation mode is an important direction for the future development of the jujube industry.The advanced stage of labor-saving is agricultural mechanization and digitization.The use of a simplified tree shape is an important prerequisite for mechanization and reduction of orchard labor.At present,the tree shape of Junzao Garden mostly adopts three main branches and happy shapes.Due to the large branches,the agricultural operations are cumbersome and the machinery is difficult to pass.This subject is based on the original tree shape of 224 groups of Junzao,and explores the growth of three main branches(6 ~ 7a)into the main shape and the three main branches into the cylindrical shape 5a.,The impact of benefits.The main findings are as follows:1 The influence of trunk shape transformation on the growth,yield,quality and benefit of Junzao(1)The tree shape has a significant impact on the growth of the Junzao tree.The one-year-old trunk shape of the transformed and cultivated tree is 5 to 20 days different from the traditional three-branched branch.The main stem shape(06-22)was advanced 20 days,compared with CK1,it was delayed by 8 days,and each period was later than the control.Crown diameter: CK1> Reformed trunk shape> Cultivated trunk shape,tree height: Renovated trunk shape> CK1> Cultivated trunk shape.(2)There is a large difference in yield composition between trees after transformation.The yield per plant is significantly different.CK1> Reformed trunk shape> Cultivated trunk shape.(3)The tree shape transformation has a great influence on the quality of Junzao.The average length and length of the fruit are CK1> reformed trunk shape> cultivated trunk shape;water content: cultivated trunk shape> reformed trunk shape> CK1;fruit soluble sugar The content was cultured trunk shape> transformed trunk shape> CK1,which was 7.35% and 4.07% higher than CK1 respectively;the titratable acid content CK1 was significantly higher than the cultured and transformed trunk shape,and the protein and vitamin C contents were not significantly different.(4)Benefit is a comprehensive index to evaluate Junzao Garden.Among the labor costs,CK1> reformed trunk shape> cultivated trunk shape,and the cost of weeding after the transformation is 79.69 yuan and 146.33 yuan lower than that of CK1;drug control: CK1 labor costs are 1.48 Times,2.44 times.2 The effect of cylindrical transformation on the growth,yield,quality and benefit of Junzao(1)After the original tree shape is transformed into a cylindrical shape by flat cutting(5a),its branch group,nutrient distribution,and lighting conditions are quite different from the original tree shape;The number of jujube hanging and the number of flowers are upper layer> middle layer> lower layer.(2)There is a difference in the total amount of mineral elements between different levels of the cylindrical tree.The total amount of mineral elements in a single cylindrical plant is less than 2.5g of the three main branches;the content of the upper layer above the different layers of the cylinder is the highest(19.91g),Higher than the middle and lower 32.14%,51.28%.Canopy characteristics: The cylindrical inner hall LAI value is significantly higher than the outer hall 2.35,1.21 higher than the inner hall of CK2,the difference between the two tree-shaped outer halls is not significant;the inclination angle of the outer hall leaves of the cylindrical and CK2 are significantly lower than the inner Hall,the cylindrical inner hall is significantly lower than CK2,a decrease of 12.12,the cylindrical outer hall is lower than CK2,a decrease of 7.14;DIFN cylindrical outer hall is significantly higher than the inner hall 0.20.(3)The yield composition of a single cylindrical plant is not much different from that of CK2,cylindrical: 1.81 kg / plant,CK2: 2.02 kg / plant;the different levels of cylindrical yield constitute the upper layer> middle layer> lower layer.(4)The single fruit weight of fresh food quality: cylindrical <CK2;the edible rate is not much different,and the moisture content is cylindrical> CK2.Inner quality: The soluble sugar in cylindrical fruits is higher than CK2,the difference is not significant,the soluble sugar content between different layers of the cylindrical upper layer <middle layer <lower layer;the titratable acid content cylindrical> CK2,the difference is not significant,the different levels of the cylindrical can be titrated Acid content upper layer> middle layer> lower layer;vitamin C content was not significantly different.(5)After adopting the cylindrical tree shape,the labor cost can be significantly reduced.The benefit of CK2 acre is lower than that of the cylindrical 169.73 yuan,which is a better tree transformation model. |
