Description
Technical Field
The invention belongs to the technical field of fertilizers, and particularly relates to a special fertilizer for purslane, which is suitable for greenhouses in northern regions, and an application thereof.
Background
Purslane (academic name: Portulaca oleracea L.): is an annual herb of Caryophyllales, Portulacaceae, and has no hair. Lying down with the stem, lying prostrate and scattered, and light green or dark red branches. The leaves are intergrowth, flat and thick, like a serrate shape, dark green on the upper surface, light green on the lower surface or dark red; the petiole is thick and short. The flower has no peduncle, and blooms in the noon; leaf-shaped; sepals are green and shaped like a helmet; yellow petals, inverted egg shape; stamen anthers are yellow; the ovary has no hair. A capsule egg-shaped; the seeds are fine, inclined spherical, black brown and glossy. The flowering period is 5-8 months, and the fruit period is 6-9 months. The purslane contains rich dihydroxyethylamine, malic acid, glucose, calcium, phosphorus, iron, vitamin E, carotene, vitamin B, vitamin C and other nutrient substances. Purslane has a remarkable characteristic in nutrition, and the omega-3 fatty acid content of the purslane is higher than that of any plant. Omega-3 fatty acid can inhibit the absorption of human body to cholesterol, reduce the concentration of cholesterol in blood, improve the elasticity of blood vessel wall, and is very beneficial to preventing and treating cardiovascular diseases. Purslane is highly humid, drought-tolerant, waterlogging-tolerant, positive, suitable for cultivation in various fields and sloping fields, and has good neutral and weakly acidic soil. The germination temperature is 18 deg.C, and the optimum growth temperature is 20-30 deg.C. When the temperature exceeds 20 ℃, the seeds can be sowed in stages and can be put on the market successively.
Based on the fact that the purslane has higher medicinal value and edible value, the purslane is widely loved by people; however, purslane is not easy to grow and develop in a low-temperature and dry environment in northern areas due to high-temperature and humidity preference of purslane, and in order to overcome the technical problems, technical personnel in the field adopt a greenhouse mode to carry out large-scale planting on purslane; the planting mode ensures the normal development of purslane, but purslane planted in a greenhouse has the defects of low yield, poor quality and less sustainable picking times compared with purslane planted in the south; furthermore, the existing purslane planting does not have special base fertilizer, and a planting user generally adopts the conventional balance base fertilizer with the effective content of nitrogen element of 15%, the effective content of phosphorus element of 15% and the effective content of potassium element of 15%; the balanced base fertilizer cannot be adjusted according to the growth requirement and fertilizer requirement characteristics of the purslane, so that the waste of effective nutrient elements is caused, and the income increase of the purslane cannot be realized.
