Technical Field
The invention relates to the technical field of vegetable cultivation, in particular to a leaf vegetable nutrient and an application method thereof.
Background
The leaf vegetables are vegetables taking tender leaves and petioles of plants as edible parts and account for 1/3-2/3 of vegetable biomass. Common leafy vegetables include rape, leek, lettuce, celery, spinach, amaranth, endive, cabbage, garland chrysanthemum, agaric and the like, and can be divided into three types of common leafy vegetables, noduliflower vegetables and spices according to cultivation characteristics. Because leaf vegetables grow fast, the cultivation period is short, and the fertilizer demand is large, in the traditional planting mode, a method of applying organic fertilizer and inorganic fertilizer mainly comprising nitrogen, phosphorus and potassium in a matching way is often adopted to meet the production requirement, so that the nutrient utilization rate is low, the damage of the soil structure is easily caused, the accumulation of harmful substances and plant diseases and insect pests in the soil are increased, and the yield and the quality of the leaf vegetables are further influenced.
Most seriously, in the current vegetable planting production process, the phenomenon that a producer applies excessive or excessive chemical fertilizers and organic fertilizers to improve the yield is gradually serious, and the caused consequences mainly comprise the following aspects: (1) although the organic fertilizer is used in a large amount, the soil hardening phenomenon can be relieved to a certain extent, but antibiotics, hormones and the like in the organic fertilizer become main sources of soil pollution; (2) the undegraded organic fertilizer becomes a main source of soil diseases and insect pests; (3) the nutrition proportion of the organic fertilizer does not meet the growth requirement of vegetables, and the residual nutrition can also be the main reason of secondary salinization of soil. Meanwhile, vegetable nutrient deficiency and nitrate content exceeding are easily caused by unbalanced proportion of organic fertilizers and inorganic fertilizers and excessive application of fertilizers, so that research on a leaf vegetable nutrient with balanced nutrition and capability of effectively promoting vegetable quality and yield and an application method thereof are urgently needed.
Disclosure of Invention
Based on the defects of the prior art, the invention provides the leaf vegetable nutrient which can effectively promote the growth of leaf vegetables and improve the quality and the yield of the vegetables and the application method thereof.
The technical scheme adopted by the invention to realize the purpose is as follows:
the leaf vegetable nutrient is characterized by comprising the following components: gamma-aminobutyric acid, phosphorus, potassium, calcium, magnesium, sulfur, iron, boron, manganese, zinc, copper, molybdenum, polysorbate-80, silicone, and organically chelated titanium;
wherein, when being used for foliage spray, include: 50-80mmol/L of gamma-aminobutyric acid, 0.5-1.0mmol/L of phosphorus, 4-6mmol/L of potassium, 2-3mmol/L of calcium, 1-2mmol/L of magnesium, 1-2mmol/L of sulfur, 50-100 mu mol/L of iron, 50-60 mu mol/L of boron, 5-10 mu mol/L of manganese, 0.7-1.0 mu mol/L of zinc, 0.1-0.2 mu mol/L of copper, 0.05-0.1 mu mol/L of molybdenum, 805-6g/L of polysorbate-organic silicon, 0.05-0.3g/L of organic silicon and 5-20mg/L of organic chelated titanium;
or when the fertilizer is used for root system dressing or seed soaking treatment, the gamma-aminobutyric acid accounts for 15-30mmol/L, the phosphorus accounts for 1.0-1.5mmol/L, the potassium accounts for 6-8mmol/L, the calcium accounts for 3-5mmol/L, the magnesium accounts for 2-3mmol/L, the sulfur accounts for 1-2mmol/L, the iron accounts for 50-100 mu mol/L, the boron accounts for 60-80 mu mol/L, the manganese accounts for 10-15 mu mol/L, the zinc accounts for 1.0-1.5 mu mol/L, the copper accounts for 0.2-0.3 mu mol/L, the molybdenum accounts for 0.1-0.2 mu mol/L, the polysorbate accounts for-805-6 g/L, the organic silicon accounts for 0.05-0.3g/L, and the organic chelated titanium accounts for 5-20 mg/L.
Further, when the leaf vegetable nutrient is used for foliage spraying, the leaf vegetable nutrient comprises the following components: 60-70mmol/L of gamma-aminobutyric acid, 0.6-0.8mmol/L of phosphorus, 4.5-5.5mmol/L of potassium, 2.2-2.8mmol/L of calcium, 1.2-1.8mmol/L of magnesium, 1.2-1.8mmol/L of sulfur, 60-80 mu mol/L of iron, 52-58 mu mol/L of boron, 6-8 mu mol/L of manganese, 0.8-0.9 mu mol/L of zinc, 0.12-0.18 mu mol/L of copper, 0.06-0.1 mu mol/L of molybdenum, 805.2-5.8g/L of polysorbate-890.25 g/L of organic silicon and 5-15mg/L of organic chelated titanium;
or when the fertilizer is used for root system dressing or seed soaking treatment, the fertilizer comprises the following components: 20-25mmol/L of gamma-aminobutyric acid, 1.2-1.4mmol/L of phosphorus, 6.5-7.5mmol/L of potassium, 3.5-4.5mmol/L of calcium, 2.2-2.8mmol/L of magnesium, 1.2-1.8mmol/L of sulfur, 60-80 mu mol/L of iron, 65-75 mu mol/L of boron, 12-15 mu mol/L of manganese, 1.2-1.4 mu mol/L of zinc, 0.22-0.28 mu mol/L of copper, 0.1-0.2 mu mol/L of molybdenum, 805.2-5.8g/L of polysorbate-890.25 g/L of organic silicon and 5-15mg/L of organic chelated titanium.
