Parsley is the market needs throughout the year and the number of green leafy vegetables is not too large, and the product is tender leaves, intolerant of storage and preservation, so it must be arranged for the anniversary of cultivation in order to meet the needs of the market. Parsley from sowing to the first harvest leaves, about 100 ~ 130 days, the continuation of the harvest 120 ~ 180 days, the fertility period of up to one year. China in addition to the southern summer high temperature areas should not be production, most areas are relatively easy to do the annual production and supply.

(1) Cultivation season and way

① Autumn sowing spring and summer harvest Southern winter is not too cold areas, can be sown in October, seedlings overwintering in the open ground (or hotbed overwintering, transplantation after the cold), the following year, May to August harvested on the market. Because of the overwintering seedlings will not sense the low temperature, so the spring will not occur first shoot phenomenon.

② winter sowing, summer and fall harvest China's Yangtze River Basin region from December to January of the following year in the protected nursery, planted in the open ground in March, May to December harvest. In the summer high temperature season to build shelves covered with shade net or rain shelter, shading and cooling to prevent rainstorms. North China, in late January to early February, the use of improved sun beds or Si light greenhouse heat preservation seedlings, early March to early April planting of open ground. harvest in mid to late May, if you can fine management, the high temperature of the summer period to take sprinkler irrigation, watering the ground cool water, can continue to be harvested to early November, before the severe winter, but also this crop of parsley can also be dug up with the soil of the old roots, transplanted to a solar greenhouse, planting more than 50 days after the harvest can be re-harvested, continuous! The leaves are harvested for about 3 months.

3 summer sowing winter harvest Yangtze River Basin in June to start direct seeding or nursery, nursery seedlings in early September planting, to start harvesting in November, until the next year in May before the flowering, with December to March can be covered with greenhouses to keep warm. North China summer sowing is in late June to early July seedlings, late August to early September planting in the improved sun beds, in mid-October, late buckle on the film, late November harvest.

(2) Cultivar selection There are four main types of parsley varieties.

①Ordinary parsley or plate leaf parsley The main root is fleshy, long conical. The basal leaves are sulphurous, flat and straight, the leaf margin notches are thick and pointed, and the main root is edible or medicinal. The leaves are suitable for use as a surprise sauce and sauce.

②Celery Leaf Parsley or NeaPlitan This type of variety is similar to the common parsley, but the difference is that it is a larger plant with thicker leaves and petioles. It is eaten like celery.

3) Crumpled-leaf parsley and dwarf crumpled-leaf parsley: The leaf margins are finely and y incised and curled, and become triple-curled, like a double-valved cockle. The basal leaves of the dwarf wrinkled leaf parsley grow in clusters and spread, and the leaf blade is broad and feathery. Elegant in appearance, it is used as a "green leaf" decoration for dishes or salads.

4) Fern leaf parsley The leaf blades are not curled, but y split into many separate thin lines, light and beautiful in appearance. It is mainly used as a garnish for plated dishes.

China grows more fern leaf parsley, and you can choose appropriate varieties according to the market demand.

(3) Planting

①Planting The choice of land: parsley likes moisture, but also afraid of waterlogging, so the planting land should choose the higher terrain, well-drained plots of land. Before planting, deep plowing, sun field, old vegetable land is best to use cobalt oxide to disinfect the soil, as well as eliminate underground pests. Sufficiently rotted organic fertilizer as base fertilizer, because parsley is mostly raw food, fertilizer should not be diluted with manure, should be based on base fertilizer. The amount of base fertilizer depends on the strength of the ground, generally should be no less than 43,000 ~ 60,000 kg per hectare of base fertilizer, available chicken manure and stable circle manure half, to be fully rotted and pour fine, evenly spread. The beds can be made into raised beds or flat beds according to the climate and terrain of each place, and set up drainage and irrigation ditches. After the beds are leveled, spray the weed ether once.

②Sowing Direct seeding or seedling, to seedling transplantation is good. The amount of seed used for direct seeding is 7.5-11.25 kg/ha, and the amount of seed used for seedling transplanting is 0.9 kg/ha.

Because the skin of parsley seeds is thick and hard, and there are oil glands, it is difficult to absorb water, germination is slow and uneven, so it is advisable to soak the seeds to promote germination. Soak the seeds about 12 to 14 hours after rinsing with water, and gently rubbed to remove the old skin, spread out to dry before sowing.

Seedling nursery should be used hole tray nursery, with 288 holes seedling tray, planting density of 30 cm x 20 cm per hectare need to seedling tray 585, substrate (charcoal: vermiculite = 2:1), 1.65 m 3. Preparation of substrate to add N: P: K two 15:15:15 15 composite fertilizer 0.75 kg.

Winter nursery, the temperature in the seedbed during the day to maintain 20 to 25 degrees Celsius, the night is not less than 15 degrees Celsius. The temperature in the seedbed is 20 degrees Celsius during the day and 10 to 15 degrees Celsius at night. Small water spraying, seedling tray nursery to see seedling potential combined with water spraying for 1 to 2 times foliar spray fertilizer. Use 0.1% potassium dihydrogen phosphate + 0.2% urea. Summer seedlings should be shaded and cooled.

3 planting Seedling transplanting, seedlings have 5 to 6 true leaves when planting to the field. Row spacing 30 to 40 cm, plant spacing 12 to 20 cm. Direct seeding should be timely inter-seedling, generally between 2 to 3 times according to the plant spacing seedlings.

(4) field management Directed field in the seedlings 1 ~ 2 true leaves, . Inter-seedling and combined with weeding. Fertilizer, 225 kg of compound fertilizer or 300-375 kg of ammonium bicarbonate per hectare, and then every other month fertilizer. After every 1 to 2 harvests during the harvest period, apply 75 to 150 kg of urea Nai Leng, or use 0.3% to 0.5% urea plus 0.3% potassium dihydrogen phosphate for foliar spraying.

Summer sowing field is best laid grass cooling, and can prevent rainfall and soil splash staining leaves. Timely removal of yellow leaves and the base of the axillary buds of the lateral branch leaves. Winter planting should pay attention to the management of temperature, timely irrigation, inconvenience drought, generally every 10 days to irrigate thorough water.

There will be aphid infestation in drought and whitefly infestation in protected areas, which need to be checked and controlled at any time.

(4) Harvesting

Parsley is an aromatic vegetable that is planted once and harvested many times for leaves, and it is necessary to have the right time and the right amount in order to ensure the quality and yield. Timely harvesting period, generally in the parsley plant leaves total 15, heart leaves have been grouped trees and lateral extension, has begun to seal the ridge when the start of harvesting, too early harvesting will affect the growth of the plant, reduce yield.

Harvesting should pay attention to the base of the ~ round of old leaves do not pick, stay for the production of photosynthetic products of the functional leaves; rely on the upper part of the newborn out of the young leaves and the end of the long into the leaves to continue to grow up, but also should be left behind to grow up and then harvesting, each time the harvesting only pick the plant in the middle of the good quality of the goods, the old and young in the middle of the 2 to 4 pieces of the leaves that have been grown into. Spring and summer every 3 to 4 days can be harvested ~ times, winter is 7 to 10 days to harvest once. Harvesting should be light, do not tear the young leaves and new shoots, in order to protect the axillary buds from damage, available scissors at the base of the leaf blade under the 1 ~ 2 cm cut.
