1987年春在河北省东部滦河流域沙地建立了44hm2(公顷)苹果园,主栽品种有长富1、长富2、岩富10、青富13等共19333株,授粉品种有红津轻、王林、澳洲青苹等共9667株,砧木均为八棱海棠,行株距约5m×3m,总计栽植29000株。1987—1996年1—10年生园44hm2累计的总产量、总产值、总投入和总效益,分别为4116.46t(吨)、1243.158万元、374.505万元和868.653万元。1993—1996年7—10年生园平均每年每公顷的产量、产值、投入和效益,分别为22.892t、6.969万元、1.833万元和5.136万元;红富士苹果于10月末至11月初采收时,无病虫果率达98.0%,平均单果重250g以上,果实浓红和鲜红的着色面积为80.0%以上,果形较端正,果肉硬度为12.6kg/cm2左右,果实可溶性固形物为16.2%左右。文内总结了主要栽培技术。
In the spring of 1987, 44 hm2 (hectare) of apple orchards were established in the sand of the Luanhe River basin in the east of Hebei Province. The main cultivars include 19333 Changfu 1, Changfu 2, Yanfu 10 and Qingfu 13, Wang Lin, a total of 9667 green apple Australia, rootstocks are Balenghaitang, line spacing about 5m × 3m, a total of 29,000 planted. From 1987 to 1996, the total output, total output, total investment and total benefit of 44hm2 in the first year of the Habitat from 1 to 10 years were 4116.46t (tons), 12.4351 million yuan, 374.505 million yuan and 8.68653 million yuan respectively . The average output, output value, input and benefit per hectare of the habitat for the 7-10 years from 1993 to 1996 were 22.892t, 6.969 million, 18.33 thousand and 5.136 million respectively. At the end of October to the beginning of November, the disease-free fruit rate was 98.0% and the average fruit weight was more than 250g. The colored area of red and red fruits was above 80.0%. The fruit shape was more correct and the hardness of pulp was 12 .6kg / cm2 or so, fruit soluble solids is about 16.2%. The text summarizes the main cultivation techniques.
