| At present,with the development of peach industry,peach production has changed from the traditional production competition to quality competition.But it steal has many problems,mainly in low yield and poor quality of peach fruit,So our study focus on How to improve and enhance the quality of peach fruit.in this study,5 year old Lu Xing Lu peaches,Luhong618 as test material,through two years field experiments,study load and nano-carbon synergistic fertilizer on peach fruit quality,to clarify the load and the nano-carbon synergistic fertilizer on fruit development and quality control effect,in order to to provide a theoretical basis for the efficient production of peach.The main results are as follows:1 The decrease of load improves the chlorophyll content of leaves and leaf net photosynthetic rate,expressed as I>II >III,III as the control,tthe difference was significant.After 30 days of treatment,compared with control,I and II LU Hong 618(Luxing)leaf chlorophyll content increased by 6.2%,3.6%(10.8%,4.1%),the difference was significant.When the fruit is ripe,compared with the control,I,II Lu hong 618 Lu(Lu Xing)the chlorophyll content increased by 12.5%,11.9%,8(7.6% 7%),the difference was significant.2 Reduce the load can accelerate the transverse and longitudinal diameter growth,in peach hardening period among different treatments had little difference,from the 20 day after thinning,compared with III,I and II were significantly accelerated,in fruit enlargement period,I treatment can be 10 days in advance about entering the mature stage.Reduce the load can accelerate the trace elements Ca,Cu,Mg,Fe,Zn in leaves.3 Load can improve the fruit quality,fruit maturity stage,Lu hong 618(Lu Xing)fruit soluble solids can reach 12.9% I,II(12.3%),12.4%(11.8%),increased 13.1%(12.8%),8.7%(8.7%)compared with III.Compared with the control,I,II treatment the average weight of fruit increased 31.5%(36.5%),16.5%(19.7%),the difference was significant.As the load is reduced,the content of Vc increased,the fruit titratable acid content,the hardness decreased gradually,so as to improve the quality of fruit.4 Compared with the control,Ca,Cu,Mg,Fe,Zn content increased significant in soil,leaves and fruits in treatment,with the increase of nano-carbon sol dosage,the content of trace elements become the first increased and then decreased.After 20 days treatment,compared with control,T1,T2,T3,Ca content in fruit was increased by 18.9%,28.7%,24.5%,Mg content increased by 8.6%,33.2%,25.8%,Cu content increased by 1.9%,7.5%,2.4%,Fe increased by 5.8%,20.9%,8.1%,Zn increased by 1.8%,14.5%,8.3%,respectively.When the fruit is ripe,compared with the control,T1,T2,T3,Ca content in fruit was increased by10.8%,13.2%,10.3%,Mg content increased by 15.4%,23.7%,8.5%,Cu content increased by3%,11.7%,4.2%,Fe content increased by 3.9%,7.5%,7.1%,Zn increased by 10.4%,15.6%,13.1%,the difference was significant.5 In nano-carbon synergistic fertilizer treatment,leaf chlorophyll content,net photosynthetic rate was significantly higher than that of the control,with the nano-carbon sol increased,the trend of decline after rising.After 20 days of treatment,compared with control,T1,T2,T3 leaf chlorophyll content increased 6.2%,10.2%,7.7%,net photosynthetic rate increased 8.8%,11.2%,5.9%;when the fruit is ripe,compared with the control,T1,T2,T3 leaf chlorophyll content increased 10.1%,16.4%,8.4%,net photosynthetic rate increased by 10.2%,17.6%,8.5%.6 When peach riping,nano-carbon synergistic fertilizer treatment could improve the average weight of fruit,yield,soluble solids,reducing Vc content,titratable acid content in fruit,thereby improving fruit quality.Compared with the control,Lu hong 618T1,T2,T3 fruit soluble solids content increased by 9.4%,11.9%,6.8%,Compared with the control,average weight is increased by 17.7%,27.5%,14.9%,yield is increased 200 kg 300kg,150 kg,and the difference was significant.The application of 150ml0.3% nano-carbon sol(nano-carbon and compound fertilizer 21% ratio)had the best effect. |
