一、试验的意义和目的苹果同一品种间不授粉结实,或授粉结实百分率很低,早在上世末叶惠特(Waite)等已有试验证明。我国省内外苹果产区,凡属品种单一,总是低产或无产。云南农谚:“苹果开花说白话”,指的也是这一问题。因此建立苹果园,确定主栽品种后,必须配置百分之十至二十的授粉品种,是提高苹果产量的重要措施之一,否则花而不实,后来虽可用高接异品种花枝或人工授粉,或花期喷射生长激素等办法加以补救,但都比较费事。
First, the significance and purpose of the experiment Apple is not pollination between the same species, or low percentage of pollination and fructification, as early as late last leaf Ye Waite (Waite) and other tests have been proven. Apple production areas inside and outside our province, where a single species, always low or no production. Yunnan Agricultural Proverb: “Apple blossom speaks”, referring to this issue. Therefore, the establishment of apple orchards, to determine the main cultivars, you must configure 10% to 20% of the pollination varieties, is one of the important measures to improve the yield of apple, otherwise spend but not real, Pollination, or flower spurt growth hormone and other means to be remedied, but are more complicated.
