The method of sowing and breeding of Yu Beauty

Yu Mei often uses sowing and reproduction, and the survival rate of transplantation is low, so it is appropriate to use open-field direct seeding. Autumn sowing is generally in early September, but it can also be sown in spring, that is, sowing when the land is thawed in early spring, using strip sowing. The suitable temperature for germination is 15 ℃ ~ 20 ℃. Because the seeds are very small, the soil of the seedling bed must be fine, the soil should not be covered after sowing, the grass cover should be kept moist, and the cover should be removed after emergence.

Because the seeds of Yu Mei are easy to scatter, after a year of planting, the environment can no longer sow, and countless seedlings will be born in place.

The beauty of Yu often uses sowing and reproduction. Because it is not resistant to transplantation, it is often used for direct seeding. If it is needed for garden layout, it is best to use a nutrition bowl or a small paper basin to raise seedlings, or it will be difficult to survive or grow poorly. According to the climatic characteristics, the sowing date is relatively cold in Northeast China, which can be used as bed direct seeding after the soil thawed during the Spring Festival; in North China, it is more than in early winter to promote it to germinate as soon as possible in spring. Because the seed is small, the sowing should be fine, using strip sowing, the row spacing is 25.30 cm, and the hay is covered on the border in severe winter to protect against cold. The family can sow it directly in the flowerpot.

When sowing, it is necessary to apply sufficient base fertilizer, and the soil that likes moist soil during the growing period should be watered at the right time. Watering should grasp the principle of "dry and wet". When planting, watering should be controlled to promote root growth, sufficient water supply after budding, and keep the soil moist.

Sowing in the pre-arranged seedling bed from September to October, the optimum temperature for germination is 20 ℃. Because the seeds are very small, the soil of the seedling bed must be fine, do not cover the soil after sowing, keep the grass moist, and uncover the cover after emergence.

After emergence, it is necessary to plant seedlings, and the row spacing of the planting plants is about 30 centimeters. when the plants grow to 6 leaves, pour water through them in cloudy days, and then transplant them; be careful not to hurt the roots when moving, and take the soil with you, and press the soil when planting. You don't have to water too much at ordinary times, just keep it moist. During the growing period, 5 times the amount of water was applied to mature urine every 3 weeks. Non-seed plants should cut off the withered flowers in time during flowering to make the rest of the flowers bloom better. The ripening period of the capsule is inconsistent and the seeds need to be harvested in batches.

When 3-4 true leaves grow after the seedlings are unearthed, the seedlings should be separated properly, with a row spacing of about 15-20 cm. If you need to transplant or basin, it is best to carry out on a cloudy day, pour water before transplanting, and dig seedlings with as much original soil as possible to avoid damage to the roots. Watering should not be excessive during the growth period, so as to keep the soil moist.

Fertilization should not be too much, otherwise excessive plant growth will affect flowering and outlook. Generally, it is possible to apply dilute pancake fertilizer and water or compound fertilizer for 1 or 2 times from pregnant buds to before flowering. The withered flowers should be cut off in time after flowering, which will make the remaining flowers bloom better and prolong the flowering period. To cultivate Yu beauty, it is necessary to implement crop rotation and avoid continuous cropping, because continuous cropping is prone to a variety of diseases and poor growth and flowering.
