Problems solved by technology

At present, in the soilless cultivation of strawberries in my country, only Zhao Hengtian and others from the Northeast Institute of Geography and Agroecology of the Chinese Academy of Sciences have invented a nutrient solution for strawberry soilless cultivation, and its large elements include N: 259.2~316.8mg L -1 , P: 30.6~37.4mg·L -1 , K: 190.8~233.2mg·L -1 , Ca: 161.1~196.9mg·L -1 , Mg: 55.8~68.2mg·L -1 ;Trace elements include Fe: 2.6250~5.9375mg·L -1 , Mn: 0.4465~0.4935mg L -1 , Cu: 0.0095~0.0105mg·L -1 , Zn: 0.0475~0.0525mg·L -1 , B: 0.5130~0.5670mg·L -1 , Mo: 0.0076~0.0084 mg·L -1 , the high N and low K in this nutrient solution formula lead to excessive vegetative growth of strawberry plants, but the fruit yield and quality are average, and this formula is only suitable for strawberry cultivation in cold regions of my country

[0034] 4) Mixing: Dilute A mother liquor, B mother liquor, and C ...

test example 1

[0040] 10 soilless cultivation greenhouses (667m2) in Laohekou City, Hubei Province 2 ), was planted on September 8, 2007, and the strawberry plants cultivated with this nutrient solution formula were harvested in batches from December 2007 to May 2008, with an average fruit output of 2250kg per greenhouse. The fruit has good luster and soluble solid The fruit content is 13.5% to 14.5%, and the fresh fruit storage period is 4 days.

test example 2

[0042] Five soilless cultivation greenhouses (667m 2 ), was planted on September 2, 2008, and the strawberry plants cultivated with this nutrient solution formula were harvested in batches from December 2008 to May 2009, with an average fruit output of 2400kg per greenhouse. The fruit has good luster and soluble solid The fruit content is 14.0% to 15.0%, and the fresh fruit storage period is 5 days.

Abstract

The invention discloses strawberry soilless culture nutritious liquid and a method for preparing the same. The strawberry soilless culture nutritious liquid consists of macroelements, trace elements and water, wherein the macroelements comprise 210 to 252mg.L<-1> N, 24.8 to 31.0mg.L<-1> P, 234 to 312mg.L<-1> K, 80.0 to 120.0mg.L<-1> Ca and 24.0 to 48.0mg.L<-1> Mg; and the trace elements comprise 2.8 to 5.6 mg.L<-1> Fe, 0.25 to 0.50 mg.L<-1> Mn, 0.01 to 0.015 mg.L<-1> Cu, 0.03 to 0.04 mg.L<-1> Zn, 0.50 to 0.60mg.L<-1> B and 0.004 to 0.006mg.L<-1> Mo. The used raw materials are KNO3, CaNO3.4H2O, MgSO4.7H2O, NH4H2PO4, NH4NO3, Fe-EDTA, H3BO3, MnSO4.4H2O, ZnSO4.7H2O, CuSO4.5H2O and NaMoO4.2H2O. The nutritious liquid of the invention has the advantages of reasonable formula, easy operation, low cost, no pollution and high yield, and is suitable for the soilless culture of the strawberry in Yangtze River basins.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and more specifically relates to a strawberry soilless cultivation nutrient solution, and also relates to a preparation method of the strawberry soilless cultivation nutrient solution. The strawberry soilless cultivation nutrient solution is suitable for the soilless cultivation of strawberries in the Yangtze River Basin. Background technique [0002] Strawberry is a perennial evergreen herb belonging to Rosaceae Fragaria (Rosaceae Fragaria). my country's strawberry cultivation has spread all over the country, from Heilongjiang in the north, Hainan in the south, Jiangsu and Zhejiang in the east, and Xinjiang in the west. Strawberry has become a popular fruit in the market because of its high nutritional value and convenient eating, and it is also an important raw material for the food processing industry. Due to the high planting efficiency, strawberry planting has become a rapidly dev...
