Research On Control Technology Of Flame Seedless Grapes During The Forcing Culture

Under the condition of forcing culture,4 years old flame seedless grapes as experimental material, studied the variety of botany character, phenophase, blossom and bear fruit, etc., at the same time to study the effects of plant growth regulator, load, and the irrigation water for flame seedless grapes.The results showed that:(1) the flame seedless grapes have very strong growth, fruit mature at the same time, high yield, strong adaptability.Under the condition of turpan promote early cultivation, bud in the mid to late February, exhibition spike in mid-march, flowering in early April, mature in late may.Ear is conical,400-600-g per spike, fruit grain of approximate circle, purple-red, 2.53 g each, and uniformity, the thin skin, flesh crisp, sweet, contains soluble solids 17% 20%, relatively open early mature 50 days.(2) single grain weight and grain length, grain width were greater than control after ga3 treatment, soluble solids content is reduced, all the processing of fruit stalk enlargement in different degrees, uneven colouring delay and generally.Comprehensive comparison, processing 2:7 day before flowering spraying ga3 in 40 mg/kg,10 days after flowering spraying gibberellic acid 100 mg/kg, increase the fruit grain, and does not affect mature relatively.(3) there is a effect of load of single grain weight, grain weight of treatment 2 (1350 kg/ 666.7 m2) is greater than the other treatment, soluble solids content is higher.Deal with 2 had the highest photosynthetic rate, and has a maximum light saturation point and there is a minimum of light compensation point, has a maximum range of light adaptation, effective utilization rate of light is the highest.(4) kobayashi bag bagging good than others.Has a good effect of bagging on April 20, bagging on May 10th, on May 1, and no difference.Have a good effect to pick a bag on May 10th, pick a bag on May 1st, May 20, with no difference.(5) drip 13 times, flame seedless grape fruit best, highest photosynthetic rate, transpiration rate is lower than other treatment obviously, got efficient use of water.
