Seed price and planting method of swallow grass

Swallow grass, also known as swallow grass, pigeon flower, hundred grass, chicken feet even, dried bird grass, pineapple flower, thousand bird flower, is a kind of cold-resistant, caring ornamental flowers. Feiyan grassland is produced in southern Europe, and now it has been planted in many places in China. In addition to the ornamental price, its whole grass and seeds have certain medicinal value. Let's take a look at the seed price and planting method of delphinium.

The price of delphinium seed

The market price of delphinium seeds has been very stable, about 350 yuan can buy a jin of high-quality delphinium seeds, this price is within the range that everyone can accept.

The seed price of delphinium will be affected by many factors, such as the yield of delphinium seeds in the current year, the amount of buying, the price of buying more is low, the price of buying less is high, and the planting season or off-season.

Second, the planting method of swallow grass

1. Temperature requirement

Swallow grass does not have high temperature requirements, it can withstand high temperature above 30 degrees in summer, and its growth is inhibited when the temperature exceeds 35 degrees. Attention should be paid to cooling to avoid diseases caused by high temperature, high humidity and poor environmental permeability. When the temperature is lower than 10 degrees in autumn, the ground surface dries up, the roots can survive the winter naturally, and germinate again when the temperature rises again in spring next year.

2. Soil requirements

Swallow grass does not have high requirements for soil and grows well in fertile, moist, well-drained acidic soil. The garden soil can meet the growth needs when planting in the ground, and in the pot, because the space in the pot restricts the development of the root system, at the same time, in order to avoid soil consolidation, organic fertilizers such as humic soil, coconut bran and mature barnyard manure can be mixed into the basin soil to improve the soil structure and increase soil fertility to ensure the nutrition needed for the growth of swallows.

3. Lighting conditions

Delphinium likes light, grows well under the condition of sufficient light, can bear shade a little, can meet the growth needs with bright scattered light during the growing period, and has sufficient light at flowering stage to ensure that the flowers are large and colorful. Some friends use sunshade net to block part of the sun to cool down in summer, which is to pay attention to the use of sunshade net with high light transmittance to avoid lack of light in order to cool down.

4. Methods of reproduction

The propagation methods of delphinium can be divided into three methods: seed sowing, ramet and cutting. the temperature of seed sowing should be kept above 15 degrees to avoid seedling death due to low temperature or unstable temperature in early spring. Wait until there are 4-6 leaves can be transplant, transplanting should be careful not to hurt the main root system. The method of plant division is generally carried out at the beginning of sprouting in early spring or when the physiological activity of the plant is weakened after the surface part of the ground is withered and yellow in autumn, usually once every two or three years. The cutting method is carried out in spring, cutting off the branches of ten centimeters at the top of the new buds as cuttings, which can take root in about three weeks. In order to improve the success rate of cutting, the cuttings can be treated with rooting powder.

5. Common diseases of delphinium

It is mainly caused by fungi, such as powdery mildew, root rot, black spot and so on. Generally, we bury or burn withered plants in time after some parts of the ground are withered and yellow in autumn, with fewer pathogens. In summer, we should pay attention to the transparency of the environment to avoid excessive humidity. Cut off the diseased branches in time when the disease occurs, and spray fungicides such as carbendazim, carbendazim or methyl topiramate. Most of the pests are aphids, night moths and other common diseases, which can be killed with common low-toxic pesticides.
