广西僮族自治区园艺学会于1964年11月6—12日在南宁举行了柑桔菠萝技术规程讨论会。 大会分二组进行讨论。柑桔组讨论拟定了柑桔品种区域化。并认为建立无病苗圃必须选用无病区接穗。过渡性苗圃必须距离病树20公尺采摘廿年生以上接穗。在果园建立中要依不同品种生态要求因地制宜配置,建园规划中配置必要防护林带以改造自然环境条件。幼龄树和成年树管理中必须依不同品种生物学特性要求拟定幼年树整形和成年树修剪、施肥、深耕熟化土壤、复盖、各种病虫害防治措施。 菠萝组讨论拟定了菠萝品种规划,夏威夷、沙拉瓦品种果型大,产量高,较耐寒,对肥力要求较高,宜选择土层深厚地区或丘陵中下坡种植。菲律宾品种果型中等大。新加坡品种果型较小耐寒力中等,宜选择在肥力中等,寒害较轻地区或丘陵地中上坡种植。经南宁园艺场研究和几年来大面积生产实践证明:用植物激素可以完全控制菠萝周年供应。拟定了应用不同激素、不同菠萝品种、不同月份使用激素的浓
Guangxi Autonomous Region Horticultural Society November 6-12, 1964 held in Nanning citrus pineapple technical regulations seminars. The meeting divided into two groups to discuss. The citrus group discussed the development of citrus variety regionalization. And that the establishment of disease-free nurseries must use non-ward scion. Transitional nurseries must pick 20-year-old scion above 20 meters from the diseased tree. In the establishment of the orchard according to the ecological requirements of different varieties of the configuration according to local conditions, construction of park planning necessary shelter belt to transform the natural environment conditions. Young tree and adult tree management must be based on the biological characteristics of different varieties of young trees and adult tree pruning, pruning, fertilization, plowing and maturation of soil, cover, a variety of pest control measures. Pineapple group discussed the development of a pineapple variety plan, Hawaii, Sarawa variety fruit type, high yield, more cold, higher fertility, should choose the deep soil areas or hills downhill planting. The Philippines is a medium-sized fruit breed. Singapore varieties of fruit less moderate cold hardiness, should choose medium fertility, less chill injury areas or uphill in the hilly planting. The study of Nanning horticultural field and large area production over the past few years proved that plant hormones can completely control the annual supply of pineapples. Developed the application of different hormones, different varieties of pineapple, hormones in different months of concentration
