How to Propagate Artichoke by Sowing

Artichoke is an annual or biennial herb in the family of Asteraceae, and it is also the national flower of Scotland, and because of its high medicinal value, it is now cultivated for medicinal purposes. Below is the sowing and propagation method of artichoke and the precautions.

Artichoke seed propagation methods

First, sowing

1, select the seed: choose the grain large, full, black, no pests and diseases, high germination rate of the seed.

2, seed: treatment with 0.3% of the polymyxin or retinyl mix seed disease prevention, insect pests can be used in the plot of phoxim mix seed insect prevention.

3, sowing period: water hyacinth seeds and seedlings are not afraid of freezing, can be top-slurried sowing, planting wheat can be planted it, the southern part of Heilongjiang Province in early April, the northern part of the second half of April. Early sowing at the right time, conducive to the water thistle first rooted, after the long seedlings, root developed, seedling Qi seedling Wang, improve yield. However, it can not be too early, too early to freeze seeds can not reach the depth, the ground temperature is low, the seedling is slow, unfavorable to keep seedlings.

Second, sowing methods

1, live. Artificial monopoly planing pits, dibble pits 20-30cm, depth of about 8-10cm, 3g of diammonium phosphate per hole, mulch 4cm, and then each dibble seed 3-4, then mulch 3-4cm. if the weather is dry, you can seat the water sowing, generally 667 The amount of seeding is about 0.5kg per square meter. Can also be manually on the ridge cradle ditch, fertilizer mulch, sowing, seed spacing 3-5cm, after sowing mulch 3-4cm.

2, mechanical sowing. With soybean precision spot seeding machine for direct seeding on the ridge. Fertilizer box fertilizer control in 667 square meters of diammonium phosphate 15kg or less, each 1 part of the seed mixed 1.5 times fried wheat, to pull apart evenly direct sowing, generally 667 square meters with 0.5kg of seed, with cooked wheat 0.75kg. western region can also be used for seeding machine flat sowing, row spacing of 60cm, spacing of 3-5cm, 667 square meters with the amount of seed 0.6kg. The amount of 0.6kg.

3, seedling. Do 120cm wide' seedbed, 667 square meters of organic fertilizer 5000kg, diammonium phosphate 15kg, evenly mixed into the bed. In the bed according to 10cm row spacing ditch 4cm deep, to seed distance 2cm sowing, and then mulch, watering, cover the small arch. After the emergence of water hyacinth, attention should be paid to the frequent removal of weeds. Seedlings can also be raised in plastic sheds with seedling seedling trays, putting 2-3 seeds in each hole.

4, transplanting. Can be moved into the field in early May. Dibble on the ridge according to the plant spacing of 20-30cm, dibble 1g of urea into the soil, put the seedlings, cover the soil, water, and then cover the soil. Because the water thistle is a taproot system, when starting the seedlings, it is necessary to dig deep and bring more soil, and the seedlings should not be too big. The transplanted branches are less, the density can be appropriately increased, each dibble can be planted 2-3 plants.

5, density. Under general cultivation conditions, the production field 667 square meters of seedlings 2000-5000. In the more fertile land in southern Heilongjiang Province, 667 square meters of seedlings about 2,000, about 3,100 in the middle, about 4,500 in the north, in loess, sandy soil and other barren land in southern Heilongjiang Province, 667 square meters of seedlings about 3,000, about 4,200 in the middle, about 5,500 in the north. If the sowing period is delayed, the density has to be increased. Mechanical large-scale harvest in the central and northern areas, May 20 to June 5 sowing, 667 square meters of seedlings can be increased to 12,000-15,000 plants.

Artichoke seeding propagation methods and precautions2

1, sowing seedlings

Artichoke is mainly sowing seedlings, usually in the spring and fall to start sowing, sowing the number of seeds per acre to keep at about 700. However, because the seed coat of the artichoke is relatively hard, so we have to do a good job of soaking the seeds before sowing. First, put the seeds into the 50 degrees of warm water soaked for half an hour, soaking process should be different stirring the seeds, to ensure that the seeds are evenly heated. Then soak in room temperature for 13-15 hours, after soaking, it will be fished out with a wet cloth wrapped in a temperature of about 22 degrees for germination. Seeds gradually whitening can start sowing, after sowing good management, artichoke seedling period is not more than two months, when the growth of six or so true leaves can be planted.

2, land preparation and planting

In the planting before to choose a good planting field, first of all, to choose his soil deep fertile, soft and permeable and no potholes of flat sandy soil. Remove soil residue from previous crops, do a good job of land preparation, deep tilling, deep plowing depth should be maintained at about 22 centimeters. After tilling, control the row spacing to make the border, and in the tilling of the ground also according to the soil area control into the appropriate amount of bottom fertilizer. The bottom fertilizer is mainly based on farmyard manure, and then when the average soil temperature is above 13 degrees, it can be properly planted. Planting control of plant spacing row spacing, to prevent planting too dense, planting depth of about 22 cm, after planting to pour enough root water.

3, seedling management

After planting, pay attention to the observation of seedling growth, when the seedlings slow down after the seedlings should be watered in time to meet the water needs of seedling growth. Then reasonable fertilizer, fertilizer should pay attention to the fertilizer method, not directly into the plant roots, should be around the plant groove fertilizer, to prevent the fertilizer burning roots. Control the proportion of nitrogen, phosphorus and potassium nutrients in the fertilizer, do not apply too much, to prevent fertilizer damage. Then in the rainy season, we should pay attention to good drainage, timely plowing and weeding, to prevent weeds from robbing the artichoke growth nutrients. In October around a few months to water enough overwintering water, after the end of November to stop watering, do overwintering preparation.

4. Overwintering management

When artichokes are overwintered, different overwintering methods should be used according to the different planting areas, for example, in the northern temperature, artichokes are unable to overwinter by themselves. Therefore, it is necessary to take the method of artificial warming and remove the leaves from the plant at the time of the first frost. When the temperature drops to about 4 degrees, the upper and middle leaves are cut off and the base is retained. Then cultivate the soil in time to raise the soil temperature and prevent the low temperatures from causing frost damage to the artichokes. Cover the soil with a layer of grain straw, and then press a layer of soil, so as to make sufficient preparations for the overwintering of northern artichokes.

The above is a simple introduction to artichoke planting techniques. After overwintering when the spring temperature gradually picks up, it is necessary to remove the cover map in time, peel off the grain stalks, and then do a good job of loosening the soil, increase the temperature of the soil, strengthen the management of water and fertilizer, and restore the growth of the artichoke.
