Study On The Comprehensive Cultivation Technique Of Almond Grafted On Wild David Peach

The almond is one of the world famous nut tree species.The almond kernel is fragrant and sweet,and the nutrition is rich.It is deeply loved by the consumers.In China,the production of the almond is only 76,200 metric tons in 2017,and the annual import volume is 140,000 metric tons for the past few years.The supply and demand relationship is seriously unbalanced,and the development prospect is very broad.In this paper,the experiment of grafting method comparison screening,variety comparison screening,growth comparison test of water and fertilizer implementated in the hollowstorage holes,growth comparison test of tree skeleton form culturing,and control comparison test of rodents were carried out in almond grove ofFenxi county.The main results are as follows.1 In Spring,the graft survival rate of single bud grafting method was 10.13%higher than that of two buds grafting.In Autumn,there was no significant difference between the 'T' type bud grafting method and the xylem bud grafting method.The growth of shoots in the trees grafted in Autumn is obviously better than in Spring.In average,the length of the primarybranch increased by 25.68 centimeters,the roughness increased by 0.10 centimeters,and the quantity increased by 11.In average,the length of the second branch increased by 6.71 centimeters,the roughness increased by 0.08 centimeters,and the quantity increased by 1517.2.'JinboNo.1' almond has good charactersof a thin shell(0.12 centimeters),a high rate of kernel(71%)and early maturity(from late July to early August).In the southern area of Lvliang Monutain,the almond grove grafted from wild david peach,the expression of the 'JinboNo.l' almond was better than 'Jinbian No.l' almond.3.The use of water and fertilizer in the hollowstorage hole has a significant effect on growth,yield and quality improvement of almond trees.After one year of implementation,the shoots increased by 27,the length increased by 18 centimeters,the roughness increased by 0.17 centimeters,the yield of each tree increased by 0.66 kilograms,and the weight of the seeds increased by 0.6 grams.4.In tree skeleton form culturingof three principal branches,the yield of tree was increased by 0.47 kilograms in the third year.The kernel was more full and the kernel weight increased by 0.2 grams.5.Rat damage to the almond caused a great yield loss(more than 50%),and the use of B nuts to inject rodenticide to kill rats can avoid harm to the non-target animals such as birds.
