本文报导了我们在调查安宁县栽种三七中发现的问题以及经过研究后,提出的几个供参考的意见。三七(Panax notoginseng(Burk)F.H.Chen)对生态因子要求严格。安宁引种三七,温度是一个主要的限制因素。它的年平均气温为14.7℃,低于三七的最适温度15-17℃。必须采取各种措施提高荫棚内温度,才能使三七正常生长发育。风大,冷凉地区栽种三七风险大。又由于总辐射和生理辐射较低,应适当提高荫棚的透光度.安宁12-4月的干燥度(K)在4以上,三七园应建在近水体有森林处,无灌溉地区不适栽种。安宁地区由于光温不足,三七结实困难,要得到成熟的果实,应采取综合措施,延长生育期,使植株体内积累更多的促进开花结果的物质。三七没有人工培育的品种,种群内存在着多态现象。育种方向为:抗逆、优质和高产。
This article reports some of the issues that we have made in the investigation of the problems found in Panax notoginseng during planting in Anning County and after some research. Panax notoginseng (Burk) F.H.Chen) requires strict ecological factors. The introduction of tranquility 37, temperature is a major limiting factor. Its annual average temperature of 14.7 ℃, less than the optimum temperature of 37 for 15-17 ℃. Various measures must be taken to raise the temperature in the shade canopy so as to make the normal growth and development of the notoginseng. Large winds, cold areas planted Panax risk. And due to the lower total radiation and physiological radiation, the translucency of the shade shed should be properly increased. The dryness (K) of the tranquility from April to April is over 4, and the Panax notoginseng should be built in the forest near the water body and the non-irrigated area Not suitable for planting. Due to the lack of light and temperature in the tranquil areas, it is difficult for the 37th of March to be solidly harvested. To obtain mature fruits, comprehensive measures should be taken to prolong the growth period so as to accumulate more substances in the plant that promote the flowering result. Not cultivated cultivars of Panax notoginseng, there is a polymorphism in the population. Breeding directions: resistance, high quality and high yield.
