工厂化育苗生产以其不同于传统育苗方法的独特优势,逐步成为一个新兴的种苗行业。许多企业在花卉工厂化育苗的主要程序、主要生长阶段及养护管理重点等方面总结出了成套的经验,值得花卉工厂化育苗企业借鉴。由于东北地区特殊的地理、气候环境,花卉工厂化育苗技术也迥异于其他地区。本文着重介绍东北地区特殊的温度环境下部分花卉工厂化育苗的技术要点。播种后出苗天数的差异东北处于高纬度地区,冬季及早春积温对花卉的苗期影响十分显著,生长期要明显长于华中、华南地区。如图1所示,本文选取维生公司在辽宁生产的几种花卉与在南方地区的同种花卉进行对比。石竹、四季海棠、三色堇等东北地区出苗天数为南方地区的1.5倍左右,其中仙客来东北地区出苗天数是南方地区的近2倍。春播长春花适宜在18℃～26℃播种,孔雀草播 Industrialized seedling production with its unique advantages of traditional seedling methods, and gradually become a new seedling industry. Many enterprises summed up the complete set of experience in the main program of flower factory seedling breeding, the main growth stage and the focus of conservation management, which is worth learning from the flower factory seedling raising enterprises. Due to the special geographic, climatic and environmental conditions in Northeast China, flower plant nursery technology is also very different from other regions. This article focuses on the technical points of some flower factories in Northeast China under the special temperature environment. Differences in the number of emergence days after sowing Northeast China is in high latitudes. Winter and early spring accumulated temperature has a significant effect on flower seedling stage, and its growing period is obviously longer than that in central and southern China. As shown in Fig. 1, this article compares several kinds of flowers produced by the Veritas in Liaoning and the same flowers in the South. Dianthus, seasons Begonia, pansy and other northeast of the emergence of the southern region of 1.5 times the number of days, which Cyclamen northeast of the emergence of the southern region is nearly twice the number of days. Spring sowing Vinca suitable for planting at 18 ℃ ~ 26 ℃, peacock grass sowing
