How much is artichoke (artichoke) per jin? When is the best time to plant and harvest? Attached planting method
Artichoke, also known as thistle, vegetable thistle, artichoke, French artichoke, artichoke, is a plant of the genus Asteraceae growing along the Mediterranean coast. So how much is artichokes per jin? When is the best time to plant and harvest? The following is arranged as follows:
It is understood that artichokes are sold for about five bar dollars, and it is 20 yuan converted into RMB.
Distribution range
Artichokes are native to the western and central Mediterranean and have spread to the eastern Mediterranean in ancient times. At that time, eat its tender leaves instead of immature flower heads. The type of flowers for consumption was first recorded in Italy around 1400. Artichokes are widely cultivated in California, France, Spain, Belgium, countries near the Mediterranean and other regions with fertile soil and mild and humid climate, and are distributed in Chinese mainland's Shaanxi and Shandong provinces.
Planting technology
Seedling propagation
1. Ramet propagation
The adult plants with strong growth were dug up in the first and middle of October, and the large tiller seedlings with more than 5 leaves were cut off and planted in a ditch at a depth of 1.5m. They were covered with soil and grass curtain for heat preservation, and the temperature in the ditch was maintained at 2m / m for 3 ℃ and planted in the spring of the second year. The warm area to the south of the Yangtze River can be planted directly in autumn, and it should be noted that each plant has a certain number of roots. The seedlings with less than 5 leaves were cut and planted in the seedling bed of solar greenhouse, the plant and row spacing was 15cmx15cm, ploughing and watering and topdressing in time, keeping the room temperature 15 Mel 20 ℃, about 10 ℃ at night, and planting when it grew to more than 5 leaves in spring next year.
2. Sowing and raising seedlings
Artichokes can be raised and sown in spring and autumn. Spring sowing in mid-late March, autumn sowing in mid-September, 667 square meters of field seed 600 ℃ 800, because the seed coat is thick and hard, soak the seeds in 55 ℃ lukewarm water (minutes), keep stirring the seeds with wooden sticks, soak the seeds for 16h (hours) when the water drops to room temperature, rinse them with clean water and wrap them with wet cotton cloth, put them into about 20 ℃ to accelerate germination, wait for the seeds to show white, and sow seeds. The seedlings were raised with 72-hole plastic hole tray or 6cmx6cm nutrition bowl with peat and vermiculite as substrate. The temperature at seedling stage was 18 ℃ and 20 min, watering as little as possible, and proper topdressing and foliar spraying after 2 leaves. The seedling age is 40m / m / m for 45d (days), and it can be planted when there are 5m / m / 7 true leaves. The characters of seedlings propagated by seeds may be different from those of female parents.
Land preparation and planting
The plots with good drainage and irrigation conditions were selected for planting, and the rotten fine organic fertilizer 3000kg was applied with a tillage depth of more than 25m. After leveling, a small high border with wide 50cm and high 20cm was made according to the distance of 1.5m, and the plastic film was laid on it. It can be planted only when the soil temperature of 10cm is stable above 12 ℃ in spring, one row per row, the distance between plants is 80mur100cm, 667 square meters, planting 500mur700 plants, the planting depth is about 20cm, and watering in time after planting.
Harvest time
For more than one-year-old plants, buds were harvested in the northern region from early May to late June. It is suitable to harvest 2d before seed bud opening, the early yield is low, the commodity value is too late, and the outer sepal of flower bud is green or lavender, with luster, and the basal sepal is the best when it is not released. Harvest should be carried out in the morning, cut with scissors from under the bud, classified storage or sale, 50murmur100g floret bracts are used as cans; 100Muth350g buds for fresh sale, with the highest yield of plants growing for 3 years, 15 flower buds can be picked per plant, generally harvesting 5mur10a (year).
