不同处理对树头菜扦插苗生物量分配的影响

Effects of Different Treatment on Biomass Distribution of Crateva unilocularis Cuttings

利用APEX缓释肥、生根粉(ABT-1)及插穗长度处理树头菜Crateva unilocularis,了解其各器官生物量分配筛选出适宜树头菜扦插繁殖的最佳配方,为树头菜的扩大繁殖和生产提供真实可行的科学依据。以树头菜一年生枝条为材料,采用不同浓度APEX缓释肥和ABT-1及不同长度插穗进行正交试验,以不施肥、清水处理、插穗长度为10 cm作为对照,扦插3个月后对其根茎叶各部分生物量进行测定并综合分析。此次试验所筛选最优方案为A_(2)B_(3)C_(1),即以2 kg/m^(3)APEX缓释肥,插穗长度20 cm,ABT-1质量浓度为50 mg/L搭配使用对树头菜插穗生长效果最佳。APEX缓释肥、插穗长度及植物生长调节剂是树头菜扦插苗生物量累积的重要因素。

Crateva unilocularis was tread with APEX sustained-release fertilizer,plant growth regulator and the length of cuttings to understand the biomass distribution of C.unilocularis in each organ,and thus screen out the best formula which was suitable for C.unilocularis cutting propagation.The result of the experiment provided a real and feasible scientific basis for the expansion and production of C.unilocularis.The orthogonal experiment was conducted with the C.unilocularis annual branches as materials,which were treated by different concentrations of APEX slow-release fertilizer,ABT-1 and cuttings with different lengths.Compared with 10 centimeters cuttings without fertilizer and water,the biomass of each part of root,stem and leaf would be measured and analyzed comprehensively after three months.The optimal scheme selected in this experiment was A_(2)B_(3)C_(1),namely,the cutting of C.unilocularis was treated with 2 kg/m^(3) APEX slow-release fertilizer,20-centermeter cuttings and 50 mg/L ABT-1.Besides,APEX sustained-release fertilizer,the length of cuttings and plant growth regulators were important factors in the accumulation of biomass for tree head cabbage cuttings.
