不同浓度营养液对温室黄瓜生长发育的影响

[目的]确定温室黄瓜在珍珠岩栽培条件下营养液的最适浇灌量.[方法]在智能温室条件下,以袋装珍珠岩为营养液载体,采用营养添加法,即将每种化学试剂放在一个营养液罐中按照一定的比例设置4个处理：T1,1∶200;T2,1∶100;T3,1∶50;T4,1∶30供给作物,以满足作物生长需要,研究不同浓度营养液长期浇灌处理黄瓜植株对其生长发育的影响.[结果]对比T1、T2、T3、T4各时期植株的根、茎、叶、果的鲜干重可知,T3处理黄瓜植株生长状态最优.[结论]霍格兰营养液稀释50倍为智能温室黄瓜无土栽培的最优施肥方式.

Effects of Different Nutrient Solution Concentration on Greenhouse Cucumber Growth and Development

[Objective] The aim was to determine the greenhouse cucumber nutrient solution of the optimal water amount under the culture condition of perlite and build a model based on the greenhouse crop growth model and the transpiration of nutrient supply management system.[Method] This experiment is under the condition of greenhouses,bags pearlite as the carrier of nutrient solution,the added value method is adopted：the each chemical reagents in a nutrient solution tank according to certain proportion set four processing：T1：1∶200,T2：1∶100,T3：1∶50,T4：1∶30 to supply of crops,to meet the growing needs,to research the growth and development of cucumber plants in which different concentration nutrient solution long-term water treatment.[Result] Research shows that thought contrasting T1,T2,T3,T4 of the plant root,stem,leaf,fruit fresh dry weight available T3 cucumber plant growth condition is the optimal approach.[Conclusion] The optimum fertilization mode of greenhouse cucumber soilless cultivation is 1∶50.
