Embodiment 1

[0009] Embodiment 1: Cyclamen hydroponic nutrient solution formula, preparation method and seedling stage cultivation test thereof.

[0010] The contents of N, P, K, Ca, Mg, B, Mn, Zn, Cu, Mo and Fe in the nutrient solution are respectively 171mg / L, 50mg / L, 256mg / L, 400mg / L, 34mg / L, 1mg / L, 0.5mg / L, 0.05mg / L, 0.02mg / L, 0.01mg / L, 4.2mg / L, pH value is 5.8. N:P in the nutrient solution 2 o 5 : K 2 The mass fraction ratio of O is 15:10:27.

[0011] The preparation method of this nutrient solution is:

[0012] The compounds of trace elements are weighed and dissolved in water, and prepared as concentrated 500 times liquid for storage. Calculate the amount of required compound according to the amount of nutrient solution, weigh Ca(NO 3 ) 2 4H 2 O and CaCl 2 Dissolve in a large amount of water, weigh NH in another container 4 NO 3 、KNO 3 、KH 2 PO 4 , MgSO 4 ·7H 2 The O mixture was dissolved in water, slowly poured into the calcium solution, and stirred evenly. Absorb ...

Embodiment 2

[0023] Embodiment 2: the influence of calcium concentration in cyclamen hydroponic nutrient solution on the growth of cyclamen

[0024] Change the concentration of calcium among the embodiment 1, all the other remain unchanged, make calcium concentration and be 200,300,400,500mg / L four kinds of cyclamen hydroponic nutrient solutions, it is respectively 200, 200, 500mg / L that the cyclamen seedling is transferred into calcium concentration In the 300, 400, and 500 mg / L cyclamen hydroponic nutrient solution, the concentration was reduced by half in the first week, the full nutrient solution was used in the second week, and the Hoagland nutrient solution was used as a control. The other various conditions were the same during cultivation. After culturing for 25 days, it was found that high calcium concentration was beneficial to root development, and the plant type increased with the increase of calcium concentration.

Abstract

The present invention relates to a kind of water cultivating nutrient solution for cyclamen and its preparation process. The nutrient solution contains N, P, K, Ca, Mg, B, Mn, Zn, Cu, Mo and Fe separately in 166-176mg / L, 45-55mg / L, 250-260mg / L, 300-500mg / L, 30-38mg / L, 0.5-1.51mg / L, 0.2-0.8mg / L, 0.2-0.8mg / L, 0.01-0.03mg / L, 0.008-0.015mg / L and 4.0-4.5mg / L, and has pH 5.5-6.0. Its preparation process includes the steps of: weighing trace element compounds and dissolving in water to compound concentrated solution, dissolving Ca(NO3)2.4H2O and CaCl2 in water, dissolving the mixture NH4NO3, KNO3, KH2PO4 and MgSO4.7H2O in water, mixing, regulating pH value with dilute H2SO4 solution and NaOH solution to 5.5-6.0. The nutrient solution can make cyclamen adapt water cultivating environment in one week.

Description

technical field [0001] The invention relates to a nutrient solution technology specially used for hydroponics of cyclamen, belonging to the field of flower cultivation. Background technique [0002] Cyclamen persicum L. is a semi-cold-resistant perennial bulb flower of Primulaceae Cyclamen. It is native to North Africa, Southern Europe, and West Asia, and is concentrated in the Mediterranean coast. It is currently the most popular in the international flower market. One of the flower varieties. With the continuous improvement of people's flower consumption level in our country, cyclamen is very popular because of its good flowering season. Cyclamen is named Yipinguan, Radish Begonia, Radish Lotus, Rabbit Ear Flower, and Petal Lotus. Because of its good flowering season, the blooming period is in the peak flower consumption seasons such as Christmas, New Year’s Day, and Spring Festival, so it is very popular among consumers. . At present, the production technology of subst...
