不同粗度苹果苗木与定植后生长结果关系的研究

STUDY ON THE CONSEQUENCE GROWING AND FRUITING AFTER PLANTING APPLE SEEDLINGS OF DIFFERENT DIAMETERS

1986—1989年在四川盐源果场对不同粗度的金冠、红星、富士苹果苗木定植后的生长结果情况进行了研究。结果表明:定植时的苗木粗度与定植后的树体生长量及单株产量有着密切的关系。培育1.5cm以上茎粗的苹果苗木有利于加速生长,早成形,早开花结果,提高早期产量。

Experiments were carried out at the fruit farm of Yanyuan in Sichuan province during 1986-89. We studied the growing and fruiting on apple trees 'Golded Delicious', 'Red Starking' and 'Fuji' after planting their seedlings of different diameters. There was a close correlation between the seedlings of different diameters and the output of growth and fruit. The authors, through analysis, believe that breeding apple seedlings of more than 1.5cm, diameter is beneficial for seedling growing, shaping, flowering and fruiting as well as increasing the early yield.
