Effects Of Three Microscale Elements And The Strength Of Nutrient Solution On Phalaenopsis's Growth

The dissertation take phalaenopsis as the research material to study the effects of elements Iron(Fe),Zinc(Zn),Boron(B) and improved Hoagland Solution strength of nutrient solutions on the nutrient solutions on the nutritional growth and reproductive growth of phalaenopsis from the outward expression and inward mechanism of plant's growth.The results of research have demonstrated that:1.Orthononal experient states that different quotas have different needs to the three elements of Iron(Fe),Zinc(Zn),Boron(B).Different nutrient solutions which have been composed and disposed by Iron(Fe),Zinc(Zn) and Boron(B) have different effect ions to phalaenopsis's nourishment and growth.In the period of phalaenopsis's nourishment and growth,iron and zinc effect on the target of form..The analysis of variancecomponet shows that the composition of Iron(Fe) of 1.4365 mg/L and Zinc(Zn) of 0.5000mg/L are conducive to the increase of blades quantity.Besides the composition of Iron(Fe) of 4.3094 mg/L and Zinc(Zn) of 0.1500mg/L is condusive to the increase of blade's area;On the other hand,the elements which have effets on the target of physiology are Iron(Fe) and Boron(B).Iron(Fe) of 2.8729 mg/L and Boron(B) of 0.2500 mg/L are composed to make an excellent expression on the target of physiology of phalaenopsis's blade.When it composed with iron of 4.3094 mg/L,0.1000 mg/L of zinc and 0.2500 mg/L boron, phalaenopsis showed relatively excellent expression on the target of form and physiology in the period of its nourishment and growth.2.Different nutrient solutions which have been composed and disposed by Iron(Fe),Zinc(Zn) and Boron(B) have an outstanding influence on the quality of phalaenopsis's blossom.Iron(Fe) have a significant influence both on peduncles and flowers;Boron(B) have a notable effect on peduncles;while,Zinc(Zn) affect flowers evidently.When Iron(Fe) are fixed as 1.4365 mg/L and Boron(B) are fixed to 0.5000mg/l,peduncles showed an excellent expression;While,when Iron(Fe) are fixed to 2.8729mg/L and Zinc(Zn) are fixed as 0.0500mg/L,flowers showed excellent expression.The level's combinations of Iron(Fe),Zinc(Zn) and Boron(B) which accommodated for the period of phalaenopsis reproduction and growth are Iron(Fe) of 1.4365 mg/L,Zinc(Zn) of 0.0500mg/L and boron of 0.2500mg/L.3.Iron distinctly effects on the absorption and utilization of nitrogen and Potassium(K) which are in the phalaenopsis's blade.With the increase of proportion of Iron's utilization and the decrease of the content of Nitrogen(N),Potassium(K) rised at the beginning and then descended.Zinc(Zn) obviously on the absorption and utilization of potassium(K) which is in the phalaenopsis's blade;With the increase of proportion of Iron's utilization,the content of Potassium(K) descended.Nevertheless,Boron's affect on the absorption and unitization of nitrogen(N) phosphorus(P) and potassium(K) the three important elements which in the phalaenopsis's blade didn't reach a significant level.4.The experiments which have the same prescriptions but different strength of nutrient solutions lead to that the strength of nutrient solutions have a significant influence on phalaenopsis's nourishment and growth.0.5～1 time of the strength of nutrient solutions are most suitable for the blade's growth of phalaenopsis.1 time of the strength of nutrient solutions is perfectly appropriate for the growth of phalaenopsis's blade.More over,it can enhance the contents of chlorophyll and soluble sugar in the phalaenopsis.Yet 2 time of the strength can make soluble protein reach the greatest value with several data from the experiments,it can't reach that the strength of 1 time of nutrient solutions is perfectly appropriate for the period of the nourishment and growth of phalaenopsis.5.Same prescriptions but different strength of nutrient solutions also affected the quality of phalaenopsis's blossom.Overall the solutions which can make the most excellent quality of phalaenopsis's blossom should be the strength of 0.5 time of the nutrient solutions.While different strength of the nutrient solutions can make divergences of the times that the peduncles send forth.You can according to specific demands to choose proper strength of solution to urge or delay the time the peduncles send forth for the market's requirement.6.Same priscriptions but different strength of nutrient solutions have a significant influence on blade's content of the three elements Nitrogen(N),Phosphorus(P),and Potassium(K).the content of two elements Nitrogen(N) and Potassium(K) in blade showed a rising tendency with the increase of the strength of nutrient solutions at the beginning.While when it reached 2 time of the strength of nutrient solutions,the content attained to maximum, the content of the two elements descended with the strength.The content of Phosphorus(P) rised with the increase of the strength of nutrient solutions from the beginning to end.
