Effects of different growing media and EC for greenhouse grown strawberries
[Objective] In order to study the effects of different growing media and fertilizer on the growth of strawberry,[Methods]we used the "Roots" strawberry as test materials,and studied the effect of strawberries' growth,yield and quality in different cultivations which were in soil cultivation and soil matrix cultivation when EC values were 1.1 mS·cm-1,1.3 mS·cm-1,1.5 mS·cm-1,1.7 mS·cm-1 and 1.9 mS·cm-1 in automatic irrigation and fertilization system,in order to find the suitable cultivation and EC.[Results]The results showed that in this area the strawberry growing in soil cultivation is better than in soil matrix cultivation;There was no significant differences in fruit weight,but yield per plant were significantly different;In terms of fruit quality,there was no difference in hardness at each processing fruit and fruit shape index,but the VC,soluble sugar content and sugar-acid ratio were significantly different.[Conclusion]The soil cultivation could make strawberries better than soil matrix cultivation in this test area.And the EC was 1.1 mS·cm-1 in soil cultivation could increase strawberries yield and make the quality better.
