Autumn sowing what flowers are better autumn has quietly come to us, autumn sowing, seedlings overwintering, the following spring and summer flowering, fruiting, and then withered, so it is also called autumn sowing flowers. Many florists asked what kind of flowers should be sown this season. The following Zuihua Network will answer this question for you.

Herbaceous flowers have the characteristics of high culture coefficient, fast growth and bright colors, so they are important materials for flower bed layout. The grass flowers commonly used in the May 1st flower beds in Fangshan area of Beijing are a string of red flowers, marigold, petunia, cold chrysanthemum, Yu Mei and so on. From September 2009 to May 2010, the author used different culture and seedling methods to cultivate marigold and petunia used in May 1st flower bed in Fangshan Garden Institute.

Planting materials and methods of grass flowers

Materials

The seeds of Petunia were collected by the base in the autumn of 2008, and the seeds of marigold were domestic F1 seeds purchased. The cuttings used in Petunia are twigs of the year.

Method

The seedling growth and plant flowering were observed and recorded in the open field combined with greenhouse cultivation in this garden, and the seedling raising effects of different culture materials and seedling techniques were compared.

Experiment on staged sowing of marigold

Sow marigold at three different times. The first was on November 15, 2009, the second on December 1, 2009, and the third on December 15, 2009.

The sowing methods are all pot sowing.

The soil is the old basin soil sifted and filled into the seedling shallow basin, flatten the topsoil, then spread the seeds evenly, the soil is about 3 mm thick, soak the basin with water at the bottom of the basin, cover with glass and put it in a shady place to be germinated.

After the seeds germinated, when the seedlings grew a pair of true leaves, the seedlings were transplanted into the nursery apparatus, and the row spacing was 5 cm × 5 cm. The seedlings were planted in the basin when they grew up, and the size of the basin was 15 cm × 10 cm. The basin soil was made from the mixture of old basin soil and cow dung according to 2: 1. Control watering at the seedling stage, dry and wet, to prevent overgrowth. Apply liquid fertilizer every 15 days, turn the pot once a week, and weed in time. In order to promote the multi-branching and pregnant buds of the plant, the heart should be picked in time. After the buds grow, in order to control the florescence, the buds that grow prematurely should be removed.

Comparative experiment on sowing and cutting of Petunia on November 4, 2009. The flower seeds were picked in the garden in the autumn of 2008, the soil was sifted and filled into the seedling shallow basin, the topsoil was flattened, and then the seeds and soil were mixed and sowed evenly without covering the soil. The pot bottom was soaked with water, covered with glass and placed in a shady place to be germinated.

The seedlings grow two cotyledons and the seedlings begin to grow when the true leaves are not unfolded. When a true leaf is grown, it is transplanted in a plastic nursery device, and the row spacing is 2cm × 2cm. On February 19, 2010, the transplanted petunia was potted for the first time, and the pot size was 10 cm × 6 cm. The potted soil was made of garden soil, rotten leaf soil and cow dung in the ratio of 4: 2: 1. More than a month later, the basin was changed for the second time, and the specification of the basin was 15 cm × 10 cm. The basin soil was made of garden soil, rotten leaf soil and cow dung according to 4: 2: 1.

Cuttings on November 4, 2009. Cut twigs from the flowers of the year as cuttings, the cuttings are 2.5 cm long, insert the last section into vermiculite, press it with your hands, spray through water and put it in a shady place. After rooting, it was put on the basin on January 8, 2010, and the specification of the basin was 10 cm × 6 cm. When the basin was changed on March 20, the size of the basin was 15 cm × 10 cm. The soil used in the basin was mixed with garden soil, rotten leaf soil and cow dung according to 4: 2: 1.

The daily maintenance and management of the two methods are similar, that is, keep moist, but not too much watering, so as to avoid excessive growth of stems and leaves. Apply more phosphorus and potassium fertilizer and less nitrogen fertilizer. The leaves of seedling stage were sprayed with potassium dihydrogen phosphate twice and irrigated once every half month after planting and maintenance. The heart was picked twice, the first on February 22, 2010, and the second on March 11.

Results and Analysis of Grass Flower planting

According to the results of marigold experiment, the seedling formation time of marigold at different sowing time was observed in order to shorten the breeding period of marigold. The data showed that the plants blooming on time before the festival could be obtained by sowing at three different times, and there was little difference in plant height, crown width, flower color and flower quantity when the flowers were in full bloom. The plants of late sowing are higher than those of early sowing, which may be related to the higher indoor temperature and the overgrowth of plants. Therefore, the room temperature should be controlled when planting in order to make the plant more robust.

The results show that the sowing time of marigold can be postponed to the middle of December, and it can also be guaranteed to blossom before International Labour Day the following year, and grow well.

The results of petunia test showed that the seeds germinated one week after sowing, germinated neatly, and the germination rate was 90%. After potting, the flower bud was seen in mid-late March 2010, and it was in full bloom on April 28, and the flower color was complex. The callus began to grow 10 days after cuttings, and took root one after another after 15 days, with a rooting rate of 96%. Buds appeared on March 15, 2010, bloomed on April 25, and the flowers and colors returned to color.

Petunia sowing and cutting were carried out on the same day, although the flowering period was different, and the cutting was two or three days earlier than sowing, the seedlings bred by the two methods could open on time before the festival. There was no significant difference in plant height, crown width, flower color and flowering quantity between sowing and cutting seedlings. The seeded Petunia seedlings are short and grow slowly at the seedling stage, with a plant height of only 2.1 cm after more than two months from germination to the first pot; cutting Petunia rooting slowly, but the rooting rate is high. The cutting petunia is more than a month apart from the cutting to the first pot, and the plant is relatively large and easy to manage. it is necessary to control water and fertilizer in the later growth stage to prevent overgrowth. Therefore, it is better to cultivate petunia by cutting in production.

Conclusion according to the above experiments, under the current cultivation conditions in Fangshan, Beijing, petunia has a good effect of raising seedlings by cutting, which has the characteristics of simple material acquisition, high rooting rate, shortening cultivation period and so on. When marigold is sown from mid-November to mid-December, festive seedlings can be obtained with little difference in quality.
