Common evening-primrose is a plant with many uses. It blooms at night like Epiphyllum, so it is also a kind of nocturnal primrose. When it blooms at night, it has a pleasant fragrance. Now we will talk about how to grow and care for Common evening-primrose.
Common evening primrose - natural disposition is strong, cold resistant and drought tolerant, barren resistance, like light, avoid waterlogging. Choose the fertile soil, good drainage of bean crop, melon crop cultivation, and can be continuous cropping. But there are green and cycling, cycling, beans, widely consumed ling herbicide residues such as straw block cannot grow Common evening primrose. Soil preparation beans and miscellaneous crops are raking autumn ridging can be straight.
Basin with substrate can choose the following a, vegetable Garden soil + slag = 3 + 1, or coarse river sand in the garden soil + + sawdust (residue) = 4 + 1 + 2, or peat + perlite + ceramsite = 2 + 2 + 1, + slag or vegetable garden soil = 3 + 1, or peat + slag + ceramsite = 2 + 2 + 1, or coarse river sand in the sawdust + vermiculite + = 2 + 2 + 1.
Seedlings when the plate in the pelvic floor in the first 2 ~ 3 cm thick coarse grained matrix or ceramsite as a filter layer, cover it with full of rotten organic fertilizer as basal, thickness of about 1 ~ 2 cm, then cover with a layer of substrate, about 1 ~ 2 cm thick. In order to separate the fertilizer from the root, avoid to burn a root, after on the basin of pouring a permeable, and in the shadow of slight environment maintenance for a week.
When seedlings are transplanted, dig planting holes first, sprinkle a layer of organic fertilizer as bottom fertilizer (base fertilizer) at the bottom of planting holes, the thickness is about 4 ~ 6 cm, and then add a layer of soil and seedlings, to separate the fertilizer from the root system, to avoid root burning. Put into the seedlings, backfill the soil, cover the root system, and foot the soil, pouring a permeable.
Seedlings are very similar to weed seedlings before the second pair of true leaves spread, which is easy to confuse. At this time, weeding can not be done by intertillage, but only after the second pair of true leaves spread. When the seedlings grow to 5 ~ 6 leaves, the grass of gramineae can be used for a lot of time to clean, fine stable killing spray grass, growth period should be two hoe and two times of ploughing, Shovel must be finished before flowering, seedlings covered with ridges for the first time hoe and ploughing. Two times of manual pulling in late July and early August were carried out to ensure that no weeds in the field exceeded the height of Common evening-primrose plants.
Common evening-primrose has infinite inflorescence, and the fruits mature gradually. Generally, the best harvest time is in the middle or late September when 3 to 4 bottom pods turn yellow and are about to crack. It can be cut and sun-dried manually or by a sun-cutter. After drying for 5-7 days, it can be picked up by a combine harvests or manually stripped (beaten). After harvesting, the seeds can be graded and sorted by a grain cleaner to remove impurities.
Common evening-primrose is a light-happy plant. When we grow and care for Common evening-primrose, it is suitable for growing in the ventilated and bright place of the yard, or on the balcony to absorb the sunlight every day.
When we grow and care for Common evening-primrose, liquid fertilizer is applied 1-2 times a month. Nitrogen fertilizer was the main fertilizer in the growth period, and phosphate and potassium fertilizer was the main fertilizer in the bud gestation period.
Common evening-primrose is drought resistant, but not waterlogging resistant. When the soil surface is dry, it should be watered in time. When we grow and care for Common evening-primrose, overplowing and weeding should be done in time to conserve moisture and ventilate, so as to promote the growth of plants.
Common evening-primrose is not strictly required for soil. Generally, neutral, slightly alkaline or slightly acidic soil is acceptable. Sand loam soil with good drainage, loose and fertile has the best growth trend.
When we grow and care for Common evening-primrose, if transplanted from other places, the Common evening-primrose should be plucked once after slow planting to promote branching and dwarfing and increase flowering.
Common evening-primrose is cold-resistant. In warm areas of the Yangtze River Basin, they can overwinter on open ground. But when we grow and care for Common evening-primrose in northern areas, if the temperature is too low, they have to be farmed in greenhouses.
