Water culture nutrient solution of blueberry and preparation method thereof

Abstract

The invention belongs to the technical field of fruit tree culture, in particular to a water culture nutrient solution prescription of a blueberry and a preparation method thereof. In the technology, the water culture nutrient solution of a blueberry comprises the following elements: 95-110mg / L of N, 10-15mg / L of P, 125-135mg / L of K, 80-90mg / L of Ca, 20-28mg / L of Mg, 4-6mg / L of Fe, 0.3-0.6mg / L of B, 0.4-0.6mg / L of Mn, 0.04-0.06mg / L of Zn, 0.02-0.04mg / L of Cu and 0.002-0.004mg / L of Mo. A pH value of the water culture nutrient solution is 4.8 to 5.5. The preparation method of the nutrient solution comprises the following steps of: weighing EDTA (Ethylene Diamine Tetraacetic Acid) ferrisodium, boric acid, manganese sulfate tetrahydrate, zinc sulphate heptahydrate, copper sulfate pentahydrate and ammonium molybdate tetrahydrate for dissolving into water and blending into 100 times of trace element mother liquor for storage and later use; additionally weighing calcium nitrate tetrahydrate, potassium nitrate, monopotassium phosphate and magnesium sulfate heptahydrate for dissolving into water; absorbing the trace element mother liquor into the solution according to the consumption; adding water for quantifying to needed volume; uniformly stirring; and adjusting the pH value of the solution to be 4.8 to 5.5 with 0.1mg / L dilute H2SO4 or dilute NaOH. By utilizing the technology, the water culture aims of growing a plurality of aquatic roots in 20 days after a blueberry seedling is transplanted and having the plant survival rate of more than 90 percent can be achieved.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a nutrient solution specially used for blueberry hydroponics and a preparation method thereof. technical background [0002] blueberry( Vaccinum ssp. ) is a treasure among fruit trees. In addition to being available for fresh food and processing, it also has a very important value for viewing flowers, fruits and leaves. [0003] Blueberry soilless cultivation technology is one of the core technologies of blueberry protected cultivation. Because the nutrients it absorbs mainly come from the nutrient solution of irrigation, not the soil, it avoids insurmountable production limitations such as continuous cropping obstacles and difficulty in transplanting seedlings. Blueberry soilless cultivation includes substrate cultivation and hydroponic cultivation. Substrate culture has relatively extensive requirements for nutrient solution because it can provide a...

AI Technical Summary

Problems solved by technology

[0005] The problem to be solved by the present invention is that the blueberry hydroponic root system under the existing nutrient solution cultivation is poor, the safety transition period is long, and the survival rate is low.
