3. Propagation methods of evening primrose

1. Seed propagation: propagate with seeds, sow in spring in the north, sow and raise seedlings in autumn or spring in various places south of the Huaihe River. When sowing, the soil should be raked fine and flat, and the seeds should be sowed on the border surface, gently raked with a rake and covered with a thin layer of soil. The seeds are small and the soil cannot be covered thick, otherwise the germination and growth of the seeds will be affected. The soil should be kept moist after the seeds are sown. About 10-15 days after sowing, the seeds can germinate seedlings.

two。 Cutting technique: the branches used for cutting are called cuttings. Usually combined with the heart-picking work, the stout, disease-free top tip is taken as a cuttage, and the top tip is inserted directly with the top tip. The optimum temperature for rooting of cuttings was 18 ℃ ~ 25 ℃, which was lower than 18 ℃, the rooting of cuttings was difficult and slow, when the temperature was higher than 25 ℃, the cuttings were susceptible to bacterial infection and rot, and the higher the temperature was, the greater the proportion of rot was. When the cuttings encounter low temperature after insertion, the main measure of heat preservation is to wrap the flowerpots or containers used for planting with thin film; when the temperature is too high after insertion, the cooling measures are mainly to shade the cuttings, to cover 50-80% of the sun, and at the same time, spray the cuttings 3-5 times a day, with more times of spraying when the temperature is higher in sunny days, lower temperatures and higher temperatures in rainy days, but less or no spraying times. After insertion, the relative humidity of the air must be kept at 750.85%.

IV. Matters needing attention in the culture of evening primrose

1. Land selection and land preparation: land preparation Evening Primrose is strong, cold-resistant, drought-resistant, barren-resistant, like light, avoid waterlogging. Bean stubble with fertile soil and good drainage should be selected, and melon stubble can be planted continuously. However, Evening Primrose can not be planted in plots with herbicide residues such as chlorosulfuron, dichlorosulfuron, Pustilon, and Guangmianling.

two。 Transplanting: when the seedlings are installed in a pot, a coarse-grained matrix or ceramsite with a thickness of 2cm or 3cm is placed at the bottom of the pot as a filter layer, and then sprinkled with a fully mature organic fertilizer as the base fertilizer, with a thickness of about 1cm to 2cm, and then covered with a layer of substrate, about 1cm thick, and then put in the plant to separate the fertilizer from the root system and avoid burning roots. You can choose one of the following substrates for potting. Vegetable garden soil: slag = 3RU 1; or garden soil: medium coarse river sand: sawdust = 4RU 1RU 2; or one of paddy soil, pond mud, rotten leaf soil. Or peat + perlite + ceramsite = 2 + 2 + 1; vegetable garden soil + slag = 3 + 1; peat + slag + ceramsite = 2 + 2 + 1; sawdust + vermiculite + medium coarse river sand = 2 + 2 + 1. Pour water once after putting on the basin and keep it in a shady environment for a week.

3. Field management: seedlings are very similar to weed seedlings before the second pair of true leaves are stretched, and can not be ploughed and weeded, but can only be entered after the second pair of true leaves are unfolded. When growing into rosette seedlings, seedlings can be fixed or transplanted. When the row spacing is 65 × 65 cm and the height of the plant is 30 cm, the soil is cultivated around the plant to prevent the lodging of plant height. After transplanting or fixing seedlings, manure or urea was applied once to promote seedling growth, and the second fertilizer was applied at the first bud to facilitate flowering and fruiting.

4. Pest control: the common diseases and insect pests of evening primrose are rot, spot blight, turtle and so on, which can be killed by related drugs.

5. Harvest and processing: evening primrose is an infinite inflorescence, the fruit ripens one after another, and half of the inflorescence can be harvested when it is ripe. When harvesting, cut (cut) the inflorescence with a branch scissors or knife, or pull up the whole plant, dry it, press it with a mill or beat it with a stick high, remove the fruit shell and impurities, and store it in a cool place.
