土壤水分调控对矮牵牛生长发育的影响

Effects of Soil Moisture Regulation on the Growth and Development of Humpback

为探明土壤水分调控对矮牵牛生长发育的影响,制定矮牵牛盆花高效栽培土壤水分管理措施提供依据。以矮牵牛重瓣豪放"双瀑布"(Double Cascade)、单瓣豪放"梦幻"(Dream)、单瓣迷你"地毯"(Carpet)3个品种为实验材料,采用盆栽试验,分析不同土壤含水量处理矮牵牛植株的生长发育变化。结果表明:当土壤湿度处于81%~90%时,矮牵牛出现烂根,植株死亡;湿度处于31%~70%的植株生长增幅与湿度大小呈正相关,并在61%~70%达到最大值;当湿度处于71%~80%时,植株徒长。

In order to find out the effects of soil moisture regulation on the growth and development of Petunia hybrid Vilmorin,the methods of soil water management for the efficient cultivation of Petunia hybrid Vilmorin were developed.The pot test was used for the three varieties of "Double Cascade","Dream" and "Carpet".Changes of growth of Petunia hybrid Vilmorin plants treated with different soil moisture content were analyzed.The results showed that when soil moisture was in the 81%~90% range,root rot appeared and plant died.Plant growth growth in the range of31%~70% of humidity was positively correlated with the size of humidity,and reached a maximum of 61%~70%;When the humidity is in the 71~80% range,the plants grow.
