Mizuna Mustard water culture formula

Abstract

The invention discloses a mizuna Mustard water culture formula which is characterized by comprising a solution A, a solution B, a solution C, iron chelate and ascorbic acid, wherein the solution A contains calcium nitrate tetrahydrate and potassium nitrate; the solution B contains dipotassium hydrogen phosphate, magnesium sulfate heptahydrate and ammonium dihydrogen phosphate; and the solution C contains boric acid, manganese sulfate, zinc sulfate, copper sulfate and ammonium molybdate. Since the growth amount of the mizuna Mustard is large, sufficient phosphate fertilizer supply is required in the whole growth season. The brassinolide is added to excite the phosphorus absorption of the mizuna Mustard, enhance the physiological functions of the plants and strengthen the photosynthesis; and by matching the chelate, the nutritional ingredients are more stable, can not be easily subjected to oxidative decomposition, and can be absorbed and utilized by the mizuna Mustard more easily, so that the growth excitation period is prolonged.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a hydroponic formula. Background technique [0002] Most of the existing hydroponic spinach formulas are general-purpose formulas. The preparation process of the existing formulas is as follows. For example, to prepare 1L of the nutrient solution prepared by this formula, it needs to be at room temperature: weigh 945 mg of calcium nitrate and 809 mg of potassium nitrate in liquid A , add one by one, stir to make it fully dissolved in the beaker (containing 600 ml of water); then weigh 153 mg of potassium dihydrogen phosphate, liquid B drug, pour the drug into the beaker while stirring fully, and add 100 ml of water, weigh Magnesium sulfate heptahydrate 493 mg, pour the drug into a beaker and stir well, and add 100 ml of water; then weigh 20 mg of ferrous sulfate, liquid C drug, 2.86 mg of boric acid, 2.13 mg of manganese sulfate, 0.22 mg of zinc sulfate, copper sulfate 0.08 mg, 0.0...

Problems solved by technology

[0003] This formula is a common formula for production, but it is easy to produce precipitation and excess nutrients during the production process, which makes it difficult for some nutrients to be absorbed and utilized by Jingshui vegetables, and Jingshui vegetables are often affected by abiotic stress during the hydroponic growth process. , such as high temperature, low oxygen, strong light, low light and other stress
