How to sow and reproduce family flowers? Methods and skills of sowing and propagation of flowers

The sowing of flowers is mainly for the better reproduction of flowers. Generally, the seeds sown are the seeds of flowers. The seedlings grown by sowing have developed root system, long life span and strong viability. Usually there are two kinds of flower sowing and propagation in the open field, so let's take a look at the methods and skills of sowing and reproduction of these two kinds of flowers together with Xiaobian.

1. Sowing and propagation of flowers in open field

The general method of sowing in the open field is as follows.

(1) the sandy soil of the seeding bed should be loose and fertile, rich in humus, and the environment should ensure good ventilation, adequate sunlight and good drainage.

(2) soil preparation and fertilization. The soil requirements of the seeding bed: ploughing 30cm deep, removing sundries, covering 12cm thick soil, with barnyard manure or rotten and fine compost as base fertilizer, the bed is flat. When sowing with calcium superphosphate to promote growth, the seeding bed should be leveled after suppression, and then flatten the bed.

(3) the depth of soil cover is different with different seed size. Generally speaking, the depth of soil cover of large seeds is 3 times of the thickness of seeds, while the degree of small seeds is that there is no seed, and the conditions permit, you can use the sieve with 0.3cm diameter.

(4) after covering the soil, cover a layer of straw evenly, and then spray water with a fine hole spray can. In the dry season, irrigate before sowing and sow the soil after infiltration to keep it moist. Rainproof facilities are needed in the rainy season. Remove the mulch when the seed is germinated and unearthed.

2. Sowing and propagation of potted flowers

Potted plants are generally raised indoors, and the sowing date has little to do with the season, generally according to the flowering period.

(1) prepare pots and soil for sowing. Shallow basin and deep 10cm, sandy soil should be rich in humus. The proportion is as follows.

① tiny seeds. Garden soil 2: River sand 3: rotten leaf soil 5.

Seed in ②. River sand 2: rotten leaf soil 4: garden soil 4.

③ big seed. River sand 1: garden soil 4: rotten leaf soil 5.

(2) the drainage hole at the bottom of the basin is covered and filled with broken pieces or coarse gravel, accounting for 1 × 3 basin depth, the top is sifted coarse-grained culture soil, accounting for 1 inch 3 thick, and the uppermost layer is seeding soil, accounting for 1 inch 3 thick. The soil surface is compacted and scraped flat so that the soil surface is 1cm away from the basin. The shallow basin is immersed in water, but it cannot be submerged. After the soil is soaked, the basin is put forward. After too much water seeps out, the seeds can be sown.

(3) Management after sowing. Keep the basin soil moist, and the seedlings gradually move to the place where the sunlight is sufficient after they are unearthed.
