Study On Cultural Practices Of Grape Nectarine And Apricot In Greenhouse

This paper through study of Comparative test of Culture of grape,nectarine and Apricot in greenhouse,influence of fruit setting rate of nectarine and Apricot by different method of pollination,Cold requirement and time of raise temperature of different varities of grape,nectarine and Apricot and PP₃₃₃influence on flower bud differentiation,fruit setting rate and young shoot growth.The effects are remarkably,in the meantime,summing up clture practices of grape,nectarine and Apricot.The results as follow:1,Comparative test of Culture of six varities of grape,three varities of nectarine and three varities of Apricot in greenhouse.The results showed that:general character of grape "jingxiu", "jingya"and "zhana"are better than grape"zi zhengxiang","xuanbajufeng","hong jing chuan",and their ecnomic effect is high,grape "zi zhengxiang","xuanbajufeng" secondary,grape "hongjingchuan" mature period is late and flower and fruit drop is serious,it is not suit to cullture in greenhouse.Fruit shape and cleanliness of surface of nectarine "shuguang" and "huaguang" in Greenhouse are better than in natural farm,nectarine "yanguang" is secondary,nectarine "huaguang"is the best,it's commodity rate is high,nectarine "shuguang" is secondary,balance of nectarine "yanguang"fruit is secondary,The number of irregular fruit is large,short of cleanliness of surface.Apricot "jingtaiyang" fruit is better,surface is clean and beautiful,good quality,mature period is early,Apricot "katta"fruit is big and has good quality,mature period is later than"jing taiyang",mature period of Apricot "zaohongshiguan" is early,fruit Cleanliness of surfane is good.2,Through test of different pollination method of nectarine and Apricot,the results showed that:fruit setting rate of nectarine and Apricot are higher than compared with control,the best method of pollination is artificial pollination with brush,but it needs long time and huge money. Spray pollen,tremble pollen and roll with chicken feather are simple,but their effect is not better, wall bee pollination effect is good.3,Through study on cold requirement of grape,nectarine and Apricot,the results showed that: The cold requirement of grape "jingya","jingxiu","zhana","zizhengxiang","xuanbajufeng", "Lizhamate","hongdiqiu" were 1250h,1280h,1300h,1600h,1520h and 1820h respectively,The time of raise temperatare of them were in 5 January,in 10 January,in middle of January,in middle of January,in late of January,in early Feb respectively.The cold requirement of nectarine "huaguang", "yanguang"," shuguang" were 770h,770h,790hrespecdively.The Time of raise temperature were in 20 Dec in 20 Dec,in 25 Dec respectively.The cold requirement of Apricot "zaohongshiguan", "jingtaiyang","katta" were 750h,790h,900h respectively.The time of raise temperature were in 25 Dec,in 25 Dec,in 5 January.4,Throuyh test of pp₃₃₃to nectarine and Apricot in greenhouse,the results showed that:the best results were found in the treatment of pp₃₃₃concentration of 300 mg/kg and 350 mg/kg,pp₃₃₃at low concentration had little influence on nectarine,but pp₃₃₃at high concentrations had significant influence on them.pp₃₃₃concentration of 150 mg/kg and 200 mg/kg had significant influence on young shoot growth and flower but differentiation first year,but it make nectarine growth to stop and dead.pp₃₃₃concentration of 450 mg/kg and 400 mg/kg had little influence on young shout growth and flower but differentiation.pp₃₃₃at low concentration had little influence on Apricot,the best results were found in the treatment of pp₃₃₃concennation of 250 mg/kg and 300 mg/kg.pp₃₃₃was sprayed upon Apricot wich various concentrations of 150 mg/kg,200 mg/kg,250 mg/kg,300 mg/kg.350 mg/kg,400 mg/kg and 450 mg/kg.The number of flower of single-tree were higher than compared with control and with the number flower increased with increasing pp₃₃₃concentration.with the rate of setting fruit decreased with incressing pp₃₃₃concentration,but them were higher against compored with control.with single-fruit weights decreased with increasing pp₃₃₃concentration...
