Selection of land preparation: choose the soil is more fertile, good water and fertilizer retention performance and more than 5 years have not been planted in the land of the coriander, then the soil deep plowing fine harrowing and leveling, and then applied to the rotted farmyard manure and make a border. Sowing: Rub the seed coat and then sow the seeds, take strip sowing as an example, the row spacing is 10-15cm, open the furrow depth of 5cm, cover the soil with 2-3cm after sowing, tread solidly with feet and water to keep the soil moist.
First, how to plant coriander
1, selecting the land rectification
(1) choose the soil is more fertile, water retention and fertilizer performance is good, good permeability and drought can be watered, flooding can be discharged as well as more than 5 years of land has not been planted with coriander, can not be re-cropped.
(2) the soil deep plowing and fine harrowing leveling, every 0.1 hectares of 3000-5000kg rotted farmyard manure, and then made beds, beds 1cm wide, beds should be based on the terrain, water and water volume.
2, sowing
(1) cilantro varieties are mainly divided into large-leafed and small-leafed, small-leafed hardy, suitable for planting in the fall, the cilantro seeds are hemispherical, the outer layer wrapped in the pericarp, in order to prevent the germination of the slow and out of the double seedling, the seeds should be rubbed before sowing before the sowing.
(2) If sown in strips, the row spacing is 10-15cm, and the furrow depth is 5cm, if sown, the furrow depth is 4cm.
(3) Strip sowing and sowing need to be covered with 2-3cm of soil, and the amount of seed used per 0.1 hectare is about 6-6.5kg.
(4) Tread solidly with your feet after sowing, and water, to keep the soil moist, which is good for seedling emergence.
3, field management
(1) check seedling
After sowing, seedling should be checked in time, if you find that the seedling emergence phenomenon of soil crusting, you need to spray water to loosen the soil, to help seedlings out of the soil, to promote growth.
(2) between the seedlings to set seedlings
① to be seedlings to grow to about 3cm time seedlings to set seedlings, usually throughout the growing period should be deep plowing, loosening the soil, weeding 2-3 times.
② the first time in the seedling top soil, with a light hand pick hoe or a small rake for light break soil skin loosening, eliminate the layer of slate, pulling out the early weeds, with the seedlings out of the soil.
③ second in the seedling height of 2-3cm, if the strip seeding should be combined with pulling weeds, with a small hoe appropriate deep loosening.
④ third in the seedling height of 5-7 cm, to be the leaf part of the ground sealed tight, no matter strip sowing or sowing, do not need to plow as well as loosening the soil, only need to pull weeds can be regularly.
(3) fertilizer and watering
① before the seedling is usually not watered, after the seedling in time to water a stabilization of water, the amount of seedlings not submerged is appropriate.
② shallow watering 5-7 times during the whole life cycle, the first three watering, should be about 10 days between watering once, from the fourth watering, should be 6-7 days between watering once.
③ Keep the soil moist frequently and control shallow water before harvest.
④ fertilizer should be combined with watering, the first watering light chase seedling fertilizer, mu of urea about 10kg, and then every 2-3 watering on the chase of a urea 10-12.5kg.
Second, when to plant the right cilantro
1, cilantro planting time
Usually cilantro in the spring and autumn seasons planting, especially in the fall planting more, which spring sowing in late March to early April, fall sowing in mid-late July to early August.
2, cilantro growth requirements of the environment
(1) cilantro low-temperature resistance, can adapt to -1-3 ℃ low temperature, the appropriate growth temperature of 17-20 ℃, the temperature exceeds 20 ℃, the growth rate becomes slower.
(2) Cilantro likes fertilizer, needs a lot of nutrients during the growth period to keep the leaf color green and the growth of leaves, so it needs fertile soil with a lot of humus.
(3) Cilantro needs short to medium sunlight, too much light will burn the leaves, so you need proper shade.
(4) cilantro likes water, the whole growing period should be watered regularly, keep the soil 60% water, but 1 watering amount should not be too much, to the soil moist without water as appropriate.
