Problems solved by technology

[0006] At present, there are many technologies related to soilless substrate cultivation of strawberries, few technologies for strawberry hydroponic cultivation of nutrient solution, the production of strawberry off-season facilities has not yet formed a scale, soilless cultivation technology is immature, and the application effect is not ideal, especially strawberry nutrition is reasonable The technical problem of supply has not been effectively solved, the yield per mu is similar to that of general cultivation, and the yield of 2000 kg has not been exceeded
Low yield and poor benefit restrict the development of facility strawberry production

Embodiment Construction

[0018] A 3000-liter nutrient solution tank was used in the test, and 3000 liters of water was added to the nutrient solution tank. The water used was local well water with a conductivity of 0.46ms and a pH value of 7.4. Add 210ml of sulfuric acid to adjust the pH value to 6.0, and add the following fertilizers Do mother liquor to make 3000 liters of nutrient solution.

[0019] Add the compound potassium nitrate KNO to the above nutrient solution tank 3 , calcium nitrate CaNO 3 4H 2 O, magnesium sulfate MgSO 4 ·7H 2 O, diammonium hydrogen phosphate (NH 4 ) 2 HPO 4 , ammonium nitrate NH 4 NO 3 , chelated iron Fe-EDTA, boric acid H 3 BO 3 , manganese sulfate MnSO 4 4H 2 O, zinc sulfate ZnSO 4 ·7H 2 O, copper sulfate CuSO 4 ·5H 2 O, sodium molybdate NaMoO 4 2H 2 O. The amount of chemical fertilizers and compounds used is calculated according to the formula W=C÷A÷P, and the addition amount of various chemical fertilizers and compounds is calculated as potassium n...

Abstract

The present invention belongs to the field of plant cultivation technology, and is nutritious liquid for soil-less cultivation of strawberry and its preparation process and usage. The nutritious liquid contains macro elements N in 259.2-316.8 ppm, P 30.6-37.4 ppm, K 190.8-233.2 ppm, Ca 161.1-196.9 ppm and Mg 55.8-68.2 ppm; and trace elements Fe, Mn, Cu, Zn, B and Mo in certain amounts. The material includes KNO3, CaNO3.4H2O, MgSO4.7H2O, (NH4)24HOP4, NH4NO3, FeEDT4, H3BO3, MnSO4.4H2O, ZnSO4.7H2O, CuSO4.5H2O and NaMoO4.2H2O, and the material is added based on certain calculation. The nutritious liquid is diluted to 1 / 3 to 1 / 2 in different growth stages of strawberry. The present invention provides strawberry with reasonable nutrients to raise its yield and quality.

Description

technical field [0001] The invention belongs to the technical field of horticultural crop cultivation, and relates to a nutrient solution for soilless cultivation of fruit trees, in particular to a special nutrient solution for soilless cultivation of strawberries and a preparation and use method. Background technique [0002] Strawberry is an energy-saving and high-efficiency horticultural crop. It is resistant to low temperature, weak light, early fruiting, and concentrated fruiting period. It is suitable for northern solar energy-saving greenhouses and large-scale modern greenhouses to promote production in winter. Compared with other conventional fruits and vegetables, it saves coal and burns. The advantages of low cost and significant economic benefits. Strawberry soilless cultivation has the advantages of water saving, fertilizer saving, not limited by soil conditions, light disease, and less or no pesticides. Due to these characteristics of strawberry, people have ca...
