1花期授粉棚室桃树必须进行花期人工辅助授粉或放蜂,以减少落花,提高坐果率。人工辅助授粉可采取人工点授、鸡毛掸滚授,两种方法均能显著提高坐果率。2适宜温度开花期最高温度要控制在20～24℃,最低温度控制在7℃以上;高温会缩短胚囊的有效授粉期,低温会降低花粉的萌发率和 A flowering peach peach greenhouse must be artificial artificial pollination or put the bees in order to reduce falling flowers and improve fruit set rate. Artificial pollination can take artificial point grant, feather duster roller grant, two methods can significantly improve the rate of fruit set. 2 suitable temperature flowering peak temperature to be controlled at 20 ~ 24 ℃, the minimum temperature control at 7 ℃ above; high temperature will shorten the effective embryo sac pollination period, low temperature will reduce the pollen germination rate and
