Sowing and breeding skills of Family Flowers

Generally speaking, sowing refers to the use of flower seeds for reproduction, so that a large number of plants can be obtained in a short time, and the roots of seedlings can be developed through sowing, with a long life and strong viability.

1. Shooting and breeding of flowers in open field

The general open sowing methods are as follows.

(1) the seedbed requires sandy soil: loose and fertile, rich in humus, the environment should ensure good ventilation, sufficient sunshine and good drainage.

(2) site preparation and fertilization. The soil requirements of the seedbed: plow 30cm deep, remove debris, cover about 12cm thick soil, use manure or rotten fine compost as base fertilizer, the bed surface is flat. When planted, it combines with calcium superphosphate to promote growth. After leveling the seeding bed, press it, and then flatten the surface of the bed.

(3) different seed size and different soil depth. The thickness of the large seed is 3 times the thickness of the seed; the small seed is not in the seed, and conditions are allowed, and a sieve with 0.3cm concentration can be used.

(4) after the soil is finished, cover a layer of straw evenly, and then spray water with a fine hole spray can. During the dry season, plant water before sowing and permeate the soil before planting to keep it moist. Rainproof facilities are needed during the rainy season. Remove the lid when the seeds germinate and dig.

two。 Sowing and propagation of potted flowers

Potted plants are usually raised indoors, and the sowing date has nothing to do with the season and usually depends on the flowering date.

(1) prepare pots for planting and soil. The shallow basin is 10 cm deep and the sandy soil needs to be rich in humus. The proportion is as follows.

1 small seed. Garden soil 2: River sand 3: humus soil 5.

2 medium seeds. River sand 2: humus soil 4: garden soil 4.

3 big seeds. River sand 1: garden soil 4: humus soil 5.

(2) the bottom of the basin is covered with drainage holes, filled with broken basin or coarse gravel, accounting for 1% of the depth of the basin. The upper part is the sifted coarse-grained culture soil, accounting for 1 per cent of the soil thickness. The top layer of planting soil accounts for 1 / 3 of the thickness. The soil surface is compacted and flattened, so the soil surface is 1 cm away from the basin. Immerse the shallow basin in water, but not immerse it. After soaking in the soil, lift the pot. After too much water seeps out, it can be planted.

(3) Management after sowing. Keep the soil moist and the seedlings will gradually move to a sunny place after they are unearthed. Figure 2 shows potted flowers sown and propagated.
