Furthermore, the proportion of the calcium nitrate and the potassium nitrate in the fertilizer A in the nutrient solution is 90.6 percent and 9.4 percent respectively.
Further, the preparation method of the fertilizer A comprises the following steps:
sequentially dissolving potassium nitrate and calcium nitrate until the potassium nitrate is clear, and then fixing the volume to the required dosage to obtain the fertilizer A.
Further, the fertilizer percentage of the B fertilizer nutrient solution is 39 percent of potassium nitrate, 7 percent of monopotassium phosphate, 17 percent of monoammonium phosphate, 35 percent of magnesium sulfate, 2 percent of chelated iron, 2 percent of chelated barrel, 2 percent of chelated manganese, 2 percent of chelated zinc, 2 percent of sodium borate and 2 percent of ammonium molybdate compound micro-fertilizer.
Further, the preparation method of the fertilizer B comprises the following steps:
(1) firstly, sequentially dissolving potassium nitrate and calcium nitrate in sequence to be clear, and then fixing the volume to the required dosage;
(2) completely dissolving iron chelate, a chelate barrel, manganese chelate, zinc chelate, sodium borate and ammonium molybdate respectively until the solution is clear;
(3) and (3) adding the (2) dissolved to be clear into the (1) to mix and fix the volume to obtain the fertilizer B.
Compared with the prior art, the invention has the beneficial effects that:
(1) the special fertilizer is suitable for large-scale production of NFT nutrient solution hydroponic leaf vegetables;
(2) the formula is applied to various leaf vegetables such as cruciferae, amaranth, various lettuce, crowndaisy chrysanthemum, fennel, Chinese chives, spinach, basella alba and the like, and good effect and yield are obtained;
(3) the formula has comprehensive nutrient elements, meets all the requirements of leaf vegetable growth, is used together with high-quality and food-grade raw materials, and can avoid the accumulation of harmful substances in the product to the maximum extent.
Detailed Description
To facilitate an understanding of the invention, the patent claims are described in further detail below with reference to specific embodiments, which may be embodied in different forms and are not limited to the embodiments described herein, but rather are provided so that the disclosure will be thorough and complete.
The specific operation mode of the invention is as follows:
example 1 is as follows:
the fertilizer suitable for being used in the production process of nutrient solution water planting leaf vegetables and the preparation method thereof comprise a fertilizer A and a fertilizer B, wherein the fertilizer A comprises calcium nitrate and potassium nitrate, and the fertilizer B comprises potassium nitrate, monopotassium phosphate, monoammonium phosphate, magnesium sulfate, chelated iron, a chelated bucket, chelated manganese, chelated zinc, sodium borate and ammonium molybdate composite micro-fertilizer.
The fertilizer is suitable for being used in the production process of nutrient solution water planting leaf vegetables and the preparation method thereof, and the calcium nitrate and the potassium nitrate in the fertilizer A are 90.6 percent and 9.4 percent respectively in the nutrient solution.
The fertilizer is suitable for being used in the production process of nutrient solution water culture leaf vegetables and the preparation method thereof, and the preparation method of the fertilizer A comprises the following steps:
sequentially dissolving potassium nitrate and calcium nitrate until the potassium nitrate is clear, and then fixing the volume to the required dosage to obtain the fertilizer A.
The fertilizer is suitable for being used in the production process of nutrient solution water planting leaf vegetables and a preparation method thereof, and the percentage of the B fertilizer nutrient solution fertilizer is 39 percent of potassium nitrate, 7 percent of monopotassium phosphate, 17 percent of monoammonium phosphate, 35 percent of magnesium sulfate, 2 percent of chelated iron, 2 percent of chelated bucket, 2 percent of chelated manganese, 2 percent of chelated zinc, 2 percent of sodium borate and 2 percent of ammonium molybdate compound micro-fertilizer.
The fertilizer is suitable for being used in the production process of nutrient solution water culture leaf vegetables and the preparation method thereof, and the preparation method of the fertilizer B comprises the following steps:
(1) firstly, sequentially dissolving potassium nitrate and calcium nitrate in sequence to be clear, and then fixing the volume to the required dosage;
(2) completely dissolving iron chelate, a chelate barrel, manganese chelate, zinc chelate, sodium borate and ammonium molybdate respectively until the solution is clear;
(3) and (3) adding the (2) dissolved to be clear into the (1) to mix and fix the volume to obtain the fertilizer B.
Comparative example 1 was used as follows:
the special liquid fertilizer is suitable for large-scale industrial NFT (nutrient solution shallow liquid flow) production of leaf vegetables, and needs to be matched with a fertilizer applicator for use, concentrated liquid fertilizers A and B are respectively placed in different fertilizer suction channels of the fertilizer applicator, the pH value is adjusted by matching with an acid channel, the EC value is set to be 1.5 at the initial stage (0-10 days) of field planting, the EC value is gradually increased to be 2.5 11-21 days after field planting, the EC value is reduced to be 1.5 21 days after field planting, and the pH value is kept between 5.8 and 6.5 in the whole growth process.
