How much is the swallow seed per jin?

The price of swallow seed is about 120,200 yuan per jin, but the price varies greatly due to the quality, variety and origin of the seed. Swallow grass has strong adaptability to climate, and the humid and cool climate is more suitable. The optimum temperature for seed germination is 15 ℃, and the suitable temperature for growth period is 20: 25 ℃ in daytime and 3: 15 ℃ at night. Like light, slightly able to withstand shade, the growing period can be in the semi-shade, the flowering period should be full of sunshine. The acid soil, which is fertile, moist and well drained, can also tolerate drought and water temperature slightly, and the best pH value is 5.5-6.0.

Sowing method of swallow grass

1. Seed collection: the ripening period of delphinium is inconsistent, and it should crack naturally after ripening, so it should be harvested in time. Generally, the ripe seeds will be harvested for 1 or 2 times in June, and all the seeds will be harvested and dried in July.

2. Sowing time: delphinium can be sown in spring and autumn. If sowing in autumn, it must be carried out in mid-September, but sowing in places with higher summer temperatures need to avoid summer vacation.

3. Post-sowing management: the optimum germination temperature of delphinium is about 15 ℃, and the best soil temperature is below 20 ℃, which germinates in about two weeks. In the north, it is generally planted in the middle of April, 2-4 true leaves and 4-7 true leaves.

The planting method of delphinium

The main results are as follows: 1. Planting: when the seeds germinate and grow 2-4 true leaves, they are transferred to the sunny border, and planted when the seedlings grow 4-7 true leaves in March of the following year, so that they can blossom from May to July, and do not plant the plants too deep when transplanting.

2. Watering: swallow grass likes to be moist and resistant to drought. When watering, it should be fully watered at one time, and when it is dry, it should be watered properly so as not to make the soil too dry.

3. Lighting: swallows need to receive enough sunlight to promote plant growth, especially in winter, tolerate certain shades, avoid strong light in summer and put them in semi-shady places.

4. Temperature: delphinium has strong adaptability to climate and likes cool weather. The best growth temperature is between 20-25 ℃ in daytime and 3-15 ℃ at night.

5. Fertilization: during the growing period, the swallows were fertilized once a month, and the phosphorus and potassium fertilizers were applied 2 or 3 times before flowering. Keeping the soil moist during the flowering period could prolong the flowering period. At the same time, cake fertilizer and water were applied once a month according to the growth status.

6. Height control: after changing the basin, paclobutrazol can be used to control the height of the plant, applying paclobutrazol (5000PPM) or paclobutrazol (1500PPM) for a long time, once every half month, until budding.

7. Diseases and pests: Swift grass commonly has black spot, root neck rot, chrysanthemum leaf blight nematode disease to damage leaves, flower buds and stems, which can be controlled by spraying 50% methyl topiramate wettable powder diluted 500 times.
