[0030] The preparation method of the strawberry soilless culture nutrient solution:
[0031] 1) Preparation of A mother liquor: Ca(NO 3 ) 2 ·4H 2 O, KNO 3 , NH 4 NO 3 Dissolve in water, make a nutrient solution and use a concentrated solution with a concentration of 100 or 200 times, and store at room temperature for later use;
[0032] 2) Preparation of B mother liquor: NH 4 H 2 PO 4 , MgSO 4 ·7H 2 O is soluble in water, prepared into a nutrient solution with a concentration of 100 or 200 times the concentration, and stored at room temperature for later use;
[0033] 3) Preparation of C mother liquor: Fe-EDTA, MnSO 4 ·4H 2 O, CuSO 4 ·5H 2 O, ZnSO 4 ·7H 2 O, H 3 BO 3 , NaMoO 4 ·2H 2 O is soluble in water, prepared as a nutrient solution using a concentrated solution with a concentration of 1000 or 2000 or 3000 times, and stored at room temperature for later use;
[0034] 4) Mixing: Dilute A mother liquor, B mother liquor, and C mother liquor with water in proportion to the use concentr...
Example
[0039] Test case 1:
[0040] 10 soilless greenhouses (667m2) in Laohekou City, Hubei Province 2 ), planted on September 8, 2007, the strawberry plants cultivated with this nutrient solution formula were harvested in batches from December 2007 to May 2008, with an average fruit yield of 2250kg per greenhouse, with good luster and soluble solid form The material content is 13.5% to 14.5%, and the fresh fruit storage period is 4 days.
Example
[0041] Test case 2:
[0042] 5 soilless greenhouses (667m 2 ), was planted on September 2, 2008. The strawberry plants cultivated with the nutrient solution formula were harvested in batches from December 2008 to May 2009. The average fruit yield per greenhouse was 2400kg.
