１０余年的试验表明，用３０万ｍｇ／ｋｇ乙烯利注射山核桃树体，在山核桃果实接近成熟时施药，果实催落率可达９０％，为对照组１０％～１５％的６～９倍。用此法不但可确保采摘人员的人身安全，降低劳动强度，提高工效１０倍以上，而且大大减少了采打成本。 More than 10 years of experiments showed that the peach tree was injected with 300000 mg / kg ethephon and the peach fruit was close to ripe when the peach fruit was close to 90% 9 times. This method will not only ensure the personal safety of picking personnel, reduce labor intensity, improve work efficiency more than 10 times, and greatly reduce the cost of hitting.
