Abstract:

The Red Fuji apple was used to study the effect of different capacity treatments on the weight of per apple, fruit exterior, inner quality, the fruit product and economic benefit during two years. The results showed that, under the medium management, the load was smaller (treatments 1 and 2), though the average weight of per apple and the fruit product were high, the fruit exterior and inner quality were better, the unit area product and economic benefit were lower; the load was too high(treatments 5 and 6), it had great disadvantage to the weight of per apple, fruit exterior, inner quality, the fruit product and economic benefit; the load maintained at 52500-60000 kg/hm2 ( treatments 3 and 4), it had less disadvantage about the fruit growth and development. It could not only assure high yield quality but also achieve sustainable development of production.
