Technical Field
The invention relates to the technical field of plant cultivation, in particular to a special nutrient solution for hydroponic milk Chinese cabbages and a preparation method thereof.
Background
The water culture milk Chinese cabbage has excellent quality, short growth period, water and fertilizer conservation, and the water culture milk Chinese cabbage has entered the industrialized production stage in recent years along with the rapid development of economy. How to design a reasonable nutrient solution formula, further improve the quality and the yield of the milk Chinese cabbage, reduce the production cost and improve the economic benefit is an important problem and a research direction of the soilless culture of the milk Chinese cabbage.
Most common formulas of common vegetables are used in the prior production, and have no pertinence, so that part of elements in the fertilizer are remained to cause waste in the using process, and the production cost is increased. More importantly, when the residual elements are accumulated in sufficient quantity, the absorption of the milk Chinese cabbage to other nutrient elements can be inhibited, so that the milk Chinese cabbage grows badly and slowly.

The second purpose of the invention is to provide a preparation method of the hydroponic milk Chinese cabbage culture solution, which comprises the following steps:
(1) weighing calcium nitrate and potassium nitrate by taking water as a solvent to prepare solution A; the concentration of each component in the solution A is 100 times of the final concentration;
(2) weighing magnesium sulfate heptahydrate, monopotassium phosphate, EDTA (ethylene diamine tetraacetic acid) chelated iron, manganese sulfate monohydrate, zinc sulfate heptahydrate, copper sulfate pentahydrate, sodium molybdate and boric acid by taking water as a solvent to prepare solution B; the concentration of each component in the solution B is 100 times of the final concentration;
(3) measuring equal amounts of solution A and solution B, and adding water until the EC value of the nutrient solution is 1.85ms/cm to obtain a nutrient solution stock solution;
(4) and preparing the nutrient solution, namely adjusting the pH value of the nutrient solution stock solution by adopting an adjusting agent to obtain the final pH value of 5.5-6.0.
The regulator is sodium hydroxide or dilute phosphoric acid.
The invention has the beneficial effects that: the nutrient solution provided by the invention can improve the quality of the milk Chinese cabbage, improve the growth speed of the milk Chinese cabbage, promote the vitamin content, improve the color of the milk Chinese cabbage and promote the root growth. The nutrient solution can ensure the normal growth of plants in various water culture production of the milk Chinese cabbages.
The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
Example 1:
preparing 100 times of special nutrient solution concentrated solution for hydroponic milk Chinese cabbages:
(1) preparing a solution A: the capacity is 100L; weighing 5.0kg of calcium nitrate (Ca (NO3)2) and 4.9kg of potassium nitrate (KNO3) and sequentially adding the calcium nitrate and the potassium nitrate into a 90L water-containing barrel, stirring to fully dissolve the calcium nitrate and the potassium nitrate, and adding water to a constant volume of 100L;
(2) and preparing a solution B: the capacity is 100L; adding 70L of water into a volumetric barrel, weighing 5.0kg of magnesium sulfate heptahydrate (MgSO 47H 2O), pouring into the volumetric barrel, uniformly stirring, adding 10L of water, weighing 1.9kg of monopotassium phosphate (KH2 PO4), pouring into the volumetric barrel, uniformly stirring, adding 10L of water, weighing 21.0g of manganese sulfate monohydrate (MnSO 4. H2O), 2.0g of zinc sulfate heptahydrate (ZnSO 4. 7H2O), 0.6g of copper sulfate pentahydrate (CuSO 4. 5H2O), 0.3g of sodium molybdate (Na2MoO 4. 2H2O) and 30.0g of boric acid (H3BO3), dissolving in the volumetric barrel one by one and uniformly stirring, weighing 250g of EDTA-Fe-13 chelate iron, dissolving in the volumetric barrel, and finally adding water to 100L;
(3) when in use, the same amount of the solution A and the solution B is measured, and water is added to adjust the EC value to 1.85ms/cm, so that the nutrient solution stock solution is obtained;
(4) and preparing the nutrient solution, namely adjusting the pH value of the nutrient solution stock solution by adopting an adjusting agent to obtain the final pH value of 5.5-6.0.
The regulator is sodium hydroxide or dilute phosphoric acid.
The present embodiment also sets a control group:
the control group differed from the present example only in that the nutrient solution formulations were the japanese garden test formulation and the kriging formulation.
The nutrient solution prepared in the embodiment is compared with a Japanese garden trial formula and a Kriging formula to cultivate the water culture milk Chinese cabbage,
the variety is 'honeysuckle-phoenix milk Chinese cabbage'. During planting, plants are placed in 3 different nutrient solutions, and 3 nutrient solutions are kept in the whole growth period
EC and PH value are consistent, and various indexes are measured after harvesting, wherein the data are as follows:
the influence on the growth vigor and the yield of the milk Chinese cabbage, the plant height, the leaf blade and the root growth condition of each cell under 3 kinds of nutrient solutions are shown in a table 1;
table 1 shows the growth conditions of plants under 3 kinds of nutrient solutions
Note: lower case letters after the numbers in the table indicate significance of difference at the 0.05 level.
As can be seen from table 1, the number of leaves of the plants under the formula of this example was significantly greater than that of the other 2 control groups at harvest, the length of the main root was longest, the weight of the single plant was greatest, and the yield was highest. The milk cabbage in the formula of the embodiment can reach 25 slices, the average root length is 39.7cm, the weight of the milk cabbage is respectively 37.4 percent and 39.3 percent higher than that of the milk cabbage in the Japanese garden test and the Kriging formula, the weight of the single overground part plant is respectively 22.3 percent and 27.8 percent higher than that of the milk cabbage in the Japanese garden test and the Kriging formula, the overground part yield is 4.5kg/m2, and the average root length is 20.6 percent and 27.8 percent higher than that of the milk cabbage in the Japanese garden test and the Kriging formula.
The influence on the nutritional quality of the milk Chinese cabbage shows that the quality of the milk Chinese cabbage under 3 nutrient solutions is shown in table 2:
table 2 shows the plant quality indexes of 3 kinds of nutrient solutions
Note: lower case letters after the numbers in the table indicate significance of difference at the 0.05 level.
As shown in table 2, the content of VC and soluble sugar in the milk-Chinese cabbage produced by the formula of this example is the highest among the 3 kinds of nutrient solutions, and particularly, the content of VC is 1.83 times that of the kriging formula.
Table 3 shows the water and fertilizer consumption of 3 nutrient solution communities
Note: lower case letters after the numbers in the table indicate significance of difference at the 0.05 level.
In a production district with the same area, the water and fertilizer usage are recorded in the whole growth period, and the yield is calculated, so that when 1kg of milk Chinese cabbage (overground part) is produced, 19.0L of water is used under the formula of the embodiment, and the water is saved by 43.4 percent and 28.0 percent respectively compared with the Japanese garden test and the Kriging formula; the formulation of this example used the least amount of macroelement fertilizer, 89.5% and 91.4% of the japanese garden test and kriging formulations, respectively.
Although the invention has been described in detail hereinabove by way of general description, specific embodiments and experiments, it will be apparent to those skilled in the art that many modifications and improvements can be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
