Planting coriander in autumn is equal to white race if it is not done at 5 o'clock.

As the old saying goes: a cold autumn rain, ten autumn rains to wear cotton. This can also be applied to crops. Autumn is the main planting season for coriander. How to grow parsley in the face of changeable weather? The following five points for attention should not be known!

First, select a good site, apply sufficient fertilizer, and prepare the land carefully.

The growth period of parsley is short, the main root is stout, it is a shallow root vegetable, and the bud soft top force is poor, and the fertilizer absorption ability is strong. Must choose in the good drainage, fertile loose, water and fertilizer conservation loam, can use early tomatoes, cucumbers, beans and so on as the previous crop. Before planting, 5000 kilograms of mature farm manure is applied every 0.1 hectare with ploughing, raking fine and leveling to make a bed, generally 1 meter wide, and the border length depends on topography and water source, so it should be beneficial to planting management, so as to promote the absorption of root system and the healthy growth of plant protection.

Second, sowing seeds

Cilantro varieties have large leaves and leaflet types. Leaflets have strong cold resistance, strong fragrance, raw food, seasoning and pickling, suitable for planting in autumn. The seeds are hemispherical and covered with a pericarp.

The seeds should be rubbed apart before sowing to prevent slow germination and double seedlings, affecting the growth of a single plant. Like cold, not resistant to heat, sowing early, high temperature, easy to bolt and blossom, more fiber, reduce yield and quality, lose commodity value. The sowing is late, the growth period is short, and the yield is low. The suitable sowing time is after the middle of August. The row spacing of strip sowing is 10 cm 15 cm, the trenching depth is 5 cm, and the trenching depth is 4 cm. Both strip sowing and sowing cover soil 2mi 3cm, and the seed consumption of 0.1 ha is 5m 5kg.

Step on it with your foot after sowing, and then water it to keep the soil moist to facilitate seedling emergence. At the same time, we should also pay attention to the phenomenon that the top of the seedling is not unearthed due to the soil consolidation before the coriander is unearthed, and check the seedlings in time after sowing. If the phenomenon of soil consolidation is found when the seedlings are unearthed, it is necessary to spray water to loosen the soil in order to help the young buds unearthed and promote rapid growth.

III. Field management

In order to create a soft and comfortable growth environment and living conditions conducive to growth and development of coriander, and to achieve the management of temperature and humidity, careful ploughing, soil loosening and weeding are the key.

The seedlings are fixed when the seedlings grow to about 3 cm. Generally, there are 3 times of ploughing, loosening soil and weeding during the whole growing period. At the top of the seedling soil for the first time, a light pickaxe or a small rake was used to slightly break the soil and loosen the soil to eliminate the plate layer. At the same time, pull out the weeds unearthed early to facilitate the seedlings to thrive.

The second time is carried out when the seedling height is 2mi 3cm, and the strip sowing can be sown with a small flat hoe to loosen the soil properly, combined with pulling out weeds. The third time was carried out when the seedling height was 5ml / 7cm. In this way, early ploughing, loosening the soil and weeding can promote the vigorous growth of seedlings. After the leaves are sealed on the ground, no matter it is sowing or sowing, they will no longer plough and loosen the soil, but just pull the grass several times purposefully.

Parsley is not tolerant to drought, so it must be watered gently every 5 rain 7 days. Basically, the whole plant is watered for 7 times during the growth period, and the soil is often kept moist. In the middle growth stage, 0.1 ha topdressing 15 kg of urea to ensure good growth.

IV. Harvesting and storage

Coriander can be harvested 30 days after sowing at high temperature and 60 days after sowing at low temperature. Harvest can be pulled out in between, but also can be harvested at one time.

In addition to recent consumption, it can also be stored for consumption in winter and spring. The freezing method of burying soil is often used for storage. Before eating, take it out and put it in a place of 10 ℃, thaw slowly, still keep the fresh and tender state, and keep the color and taste undiminished.

Fifth, do a good job of "three defenses"

1. Prevent coriander from breaking the heart caused by Rain Water

Although there is no heavy rain in autumn compared to summer, continuous autumn rain is common. After the emergence of coriander, the biggest fear is that too much Rain Water leads to its bad heart. Therefore, it is necessary to do a good job in preventing Rain Water in the autumn, in addition to timely hoeing and drainage after rainfall, it can also be watered and sprayed with a new high-fat membrane. This can effectively prevent coriander from heartache caused by too much Rain Water, but it is advisable not to drown the seedlings when watering.

2. Prevent parsley from bolting.

I believe many farmers have encountered, that is, parsley planted in summer and autumn is easy to bolting, while parsley eats its tender stems and leaves, once bolting, it can not be sold. The reason why parsley is easy to bolt in autumn, the main culprit is long sunshine. Therefore, in order to prevent the bolting of parsley, we must first start from the variety and select the excellent varieties that are resistant to bolting. Secondly, it is necessary to strengthen the management of water and fertilizer in the process of growth, and at the same time, it can also be sprayed with 800-fold liquid of new high-fat film, which can effectively reduce the probability of parsley bolting. As for watering, even for coriander planted in autumn, it is recommended that small water should be irrigated during the whole growth period, and seedling fertilizer can be lightly recovered while topping, and urea is recommended in this regard.

3. Anti-coriander red stalk

The main reason for the red stalk of parsley is that it is exposed to strong light for a long time, especially in the seedling stage of parsley, if the seedlings are too late, it will seriously cause the red stalk of parsley. Now that we have found out the reason for the red stalk of parsley, it is convenient to control it, such as time seedlings, which should be sooner rather than later, and a new high-fat membrane can be sprayed at the same time. Another point is to do a good job of shading measures, you can build some simple shade for coriander, or cover a sunshade net.
