Study On Key Protected Cultivated Techniques Of Strawberry In Shaanxi Province

In recent years,Strawberry spreads rapidly in Shaanxi.The cultivation area is more than 2000hm~2 in which 80%is protected land.However,there are some problems in strawberry cultivation.Focusing on all these problems in practical,the author took different protected conditions and cultivation method of several strawberry cultivation bases as experimental materials and designed some trials which are "the effect of interplanting with melon on the yield reduction of continuous strawberry cropping in tunnel","research on the optimal cultivation density of strawberry in solar greenhouse",and "comparison of the same variety of strawberry cultivated under different protected conditions".The results show:1.Interplanting with melon can reverse the yield reduction of continuous strawberry cropping to some extent,but can not nullify it completely.2.Introducing new strawberry variety and interplanting with melon could raise the benefit of strawberry cultivation because there are more outputs which are strawberry and melon together as well as getting more profit from sale of strawberry plantlet and the fruit of strawberry and melon.3.For strawberry high-ridged cultivation in solar greenhouse,the yield and profit increase with reduction of distance between two plants from 18cm to 10cm when the distance between two rows is 25cm.But the magnitude of increase of yield decreases as the distance between two plants decreasing.4.Under the condition of high-ridged cultivation in solar greenhouse,the effect of cultivation density of strawberry on yield and profit depends on the height of ridges.When the height of ridges increases,the potential of yield and profit is higher.5.For the same variety of strawberry,yield and profit are different under different cultivation conditions because the fruits ripe at different time.And the type of protected field and management depend on the variety characters of strawberry and when the fruits come into market.
