1花卉种子萌发所需要的条件1.1基质基质将直接改变影响种子发芽的水、热、气、肥、病、虫等条件,一般要求细而均匀,不带石块、植物残体及杂物,通气排水性好,保湿性能好,肥力低且不带病虫。1.2水分种子吸水能力因种子的构造不同而差异较大。如文殊兰的种子,胚乳本身含有较多的水分,播种时吸水量就少;有一些花卉种子较干燥,吸水量就大,播种前的种子处理很多情况下就是为了促进吸水,以利于萌发。1.3温度花卉种子萌发的适宜温度,依种类及原产地的不同而有差异。通常原产于热带的花卉所需温度较高,而原产于亚热带及温带者次之,原产于温带北部的花卉则 1 flower seed germination conditions needed 1.1 substrate matrix will directly affect the seed germination of water, heat, gas, fertilizer, disease, insects and other conditions, the general requirements of fine and uniform, without stones, plant debris and debris, Ventilation and drainage is good, moisturizing performance, low fertility and without pests. Water-absorbing capacity of 1.2 seeds due to the different structures and different. Such as Manjuslan seeds, the endosperm itself contains more water, less water when sowing; some flower seeds are drier, water absorption is large, sowing seeds in many cases is to promote water absorption in order to facilitate germination. 1.3 Temperature Germination of flower seeds suitable temperature, according to the type and origin of the difference. Usually native to tropical flowers require higher temperatures, while native to the subtropical and temperate followed, originating in temperate northern flowers
