我省太行山区飞播效果较好、面积较大的播区有上百个,成苗面积近百万亩。这些播区,多数处于交通不便、生产水平低、经济落后的深山区。充分开发利用各种自然资源,建立合理的农、林、牧、副产业结构,产生最佳经济效益、生态效益和社会效益,在飞播林区开展无病毒红富士苹果的栽培是很有必要的。一、试验园的基本情况试验地选在太行山中部,石家庄市平山县后片播区,此播区1978年进行了油松飞播造林,播区总面积为40040亩,成苗效果45%,播区海拔范围650—1190米,基岩为花岗片麻岩,土壤类型为棕褐土,年平均降水为670毫米,年平均温度10度,无
Taihang Mountain area in our province is better than aerial flight, there are hundreds of large area broadcast area, nearly one million mu of mature area. Most of these broadcasters are located in the mountainous areas with inaccessible transportation, low production levels and backward economy. It is necessary to fully exploit and utilize various natural resources and establish a reasonable structure of agriculture, forestry, animal husbandry and sideline industries to produce the best economic, ecological and social benefits. It is necessary to develop virus-free Red Fuji apples in airborne forest areas . First, the basic situation of the experimental park Experimental selection in the central Taihang Mountain, Pingshan County, Shijiazhuang post-broadcast area, the broadcast area in 1978 for pine afforestation afforestation, sowing a total area of 40,040 acres, seedling effect 45%, sowing The area of 650-1190 meters above sea level, bedrock granite gneiss, soil type is brown soil, the average annual rainfall of 670 mm, the annual average temperature of 10 degrees, no
