Primary Research On Different Gardening Measures Affects Growth And Yield Of Luntai White Apricot

The effects of different gardening measures was studied in this paper, through theresearch on organic fertilizer application、main branch adjustment、pollination and branchgrowth chemical adjustment of Luntai White Apricot The means results are as follows:(1)The organic fertilizer(sheep manure) was applied to apricot orchard(3m×5m) which shouldnot low to1200kg/mu. Meanwhile, need to replenish chemical fertilizer timely, forpromoting growth and development of fruits.(2) During the management of flower phases, both of artificial pollination and releasehoneybee are efficient path to raise Fruit-bearing rate and Yield per tree of Luntai WhiteApricot. Artificial pollination according to the ratio(5g pollen+15kg water+1000gglucose powder+3g boric acid), can assure90%flowers come into contact with pollen. Weshould release before2-3days of flower phases, with1case honeybee covering1.0-1.5muapricot orchard for10-12days.(3) Different main branch angle of Luntai White Apricot have a marked effect onFruit-bearing rate and yield per tree. Comparing with30。、90。and natural tree form,60。perform best.(4) It can effectively curb shoot growth and raise yield per tree by applicating paclobutrazol totree which5years old. Soil application paclobutrazol have a strong inhibitor of shoot growth，and can work for3years. The second year perform best, yield was raised27%.And theconsumption of paclobutrazol is1.5g/m~2. Spraying paclobutrazol can effectively curb shootgrowth in a shot time. Compared with CK, yield per tree was raised17.5%. Sprayingconsumption of paclobutrazol is500mg/kg, and use it at the middle of April、May、Junetotally to3times.
