高粱泡(Rubus lambertionus Ser.)是一种有利用价值的野生果树资源。其优点为:(1)结果早,产量高,亩产量可达500kg以上;(2)适应性广,耐瘠薄,是开发利用低山丘陵的优良资源植物;(3)果实营养丰富,酸味纯正,尤其是所含红色素稳定性好,是加工果汁饮料的优质添加剂;(4)果实采收期在11月中旬到12月底,此时气温低,有利于浆果加工和贮藏,并可利用农闲季节的劳动力。上述特点表明,高粱泡有很好的开发利用前景。但本种在野生状态下蔓生性强,多刺,并具有枝顶生根的习性,因而树形紊乱而松散,栽培时搭架困难,植株占地面积大,而单位面积产量不易提高。为了便于操作管理和提高产量,减少栽培成本,增进经济效益,我们于1990～1991年进行了生长和株形调控试验,
Rubus lambertionus Ser. Is a valuable wild fruit tree resource. Its advantages are as follows: (1) The results are early, the yield is high, the yield per mu can reach more than 500kg; (2) The wide adaptability and barrenness are excellent resource plants for exploiting hilly land; (3) The fruit is rich in nutrition and pure in acidity , Especially the stability of the contained red pigment is a good additive for processing the fruit juice drink; (4) The harvest period of the fruit is from mid November to the end of December, when the temperature is low, which is favorable for the processing and storage of the berry, Season’s workforce. The above characteristics show that sorghum bubble has a good prospect of development and utilization. However, the species is highly invasive and prickly in the wild, and has the habitat of twig-rooting. Therefore, the tree is disorganized and loose, and it is difficult for the tree to be erected when planting. The plant covers an area of a large area and the yield per unit area is not easily increased. In order to facilitate the operation and management and increase the yield, reduce the cost of cultivation, and enhance economic efficiency, we conducted growth and plant shape regulation experiments from 1990 to 1991,
