How can coriander produce high yield? High-yield cultivation techniques of coriander

Coriander is a tasting vegetable that many people like. Chinese medicine believes that coriander is warm and sweet, can stomach and digest food, sweat and rash, diuretic laxative, and detoxification. Coriander is rich in nutrients. Coriander contains vitamin C, carotene, vitamin b1, b2 and so on. The amount of vitamin C contained in parsley is much higher than that of ordinary vegetables. Generally, people who eat 7-10 grams of coriander leaves can satisfy the body's demand for vitamin C. How can the coriander produce high yield? The following small series introduces everyone to the high yield of coriander. Cultivation techniques.

Coriander germination method

Soak seeds with 1% potassium permanganate solution for 15 minutes or soak seeds with 10% carbendazim WP solution for 30 minutes, remove and wash, take out and germination at 20-25 °C.

Coriander variety selection

Coriander has large leaf varieties and lobular varieties. Although the yield of lobular varieties is not as high as that of large leaf varieties, it has strong aroma, cold tolerance and strong adaptability. Therefore, it is generally cultivated to select more lobular varieties.

Site preparation

Choose the land with loose soil, rich in organic matter, convenient drainage and irrigation. After harvesting the front crop, turn it in time, deep 15-20 cm, let it weather and dry for more than 2 weeks, then spread the high-quality farmyard fertilizer 4000 per mu. ― 5,000 kg, compound fertilizer 10-15 kg as the base fertilizer, after the cultivation, the width of the glutinous rice is 140-150 cm, the height is 20-25 cm, long depending on the length of the plot, the width of the ditch is 30-40 cm, and it is also used as a sidewalk. The kneading surface requires the soil to be finely divided, loose, and smooth. If the strip is used, it should be planted in the back surface with a row spacing of 8-10 cm and a width of 4-5 cm and a depth of about 2 cm.

Coriander sowing

From the end of August to the beginning of spring in the spring of April, you can plant at any time. Open the seeds before planting, then put the seeds in hot water at 50-55 °C, stir and simmer for 20 minutes, and continue until the water temperature drops to about 30 degrees. Seed soaking, sowing after 18-20 hours, or sowing after germination. Generally, 2-3 kg of seeds are planted per mu.

Coriander water and fertilizer management

Coriander is moist and should be watered frequently to keep it moist. It is also possible to irrigate the furrow irrigation when the soil is slightly dry. However, after the wet soil is wet, the water in the field ditch should be drained in time to avoid affecting plant growth.

Coriander light temperature requirements

Coriander can withstand a low temperature of -1 to -2 degrees, and the optimum temperature for growth is 17-20 degrees. Slow growth is more than 20 degrees, and growth stops after 30 degrees. Hi light, also resistant to yin. If the sunshade is about 50% in the autumn, and the water mist is sprayed frequently, the transverse arch film or greenhouse insulation during winter and early spring cultivation can improve the yield and quality.

Harvesting parsley

Coriander can be harvested 6-9 weeks after sowing, and roots are dug up during harvesting to remove dirt and old yellow leaves and other impurities. After washing, the bundles are sold. The average yield per mu is 1000-2500 kg, and the high yield can reach more than 3000 kg.

Coriander planting

1. Spread a layer of soil in the finished plastic bottle (the part with the cap). The soil should be fertile and loose, which is conducive to the growth of coriander. It is doubted that coriander is a short growing period, the main root is thick, and it is a shallow root vegetable, and the soft top force of the bud is poor, and the ability to absorb fertilizer is strong. Therefore, it must be chosen on the loam with good drainage, fertile and loose, water and fertilizer.

2. Start planting, then rub it with your hands and then water it to keep the soil moist and easy to produce coriander seeds.

3. During the growth of seedlings, it is necessary to observe the growth of coriander seedlings regularly, and the coriander is not drought-tolerant. If soil compaction occurs, it means that the soil needs to be watered in time to ensure sudden moistening.

4. It’s time to harvest! Go and harvest the parsley.

Coriander cultivation method after autumn

The cultivation method of organic coriander after the beginning of autumn is related to the yield of coriander. In this period, the cultivation of organic coriander should be three.

Anti-twitching. Organic coriander grown in summer and autumn, although it will not be twitched due to low temperature in the seedling stage, but will be twitched due to long-term sunshine (conditions) in summer and autumn, which requires the selection of coriander-resistant coriander varieties in production. In addition, the management of fertilizer and water (when topping water, lightly picking up seedlings) can reduce the occurrence of convulsions.

Anti-"red stalk". Coriander "red stalk", that is, the stem and leaf parts of coriander changed from green to red, reducing the commercial value of coriander, and the purchase price was halved. The coriander grown in the open field in summer and autumn will be reddened by strong light, especially when the seedlings are too late (plant height exceeds 8 cm). In order to prevent the emergence of "red stalks" in coriander, one is the morning seedlings, and the new high-fat film is sprayed once in the seedlings. In the production, it is better to grow the seedlings to 3 cm high, and keep the plant spacing after the seedlings at 2 cm. The second is to cover the shade net. The qualified farmers can take a scaffold with a height of 80-100 cm after sowing, and the shed is covered with a shade net.

Rainproof. In summer and autumn, there is more rain, which is very harmful to the coriander seedlings just after emergence. After the heavy rain, it will suddenly turn fine, which will easily lead to the bad heart of the parsley. After the rain, lightly pour the well water, the amount is not to submerge the seedlings, spray a new high-fat film once, can prevent the coriander rotten heart.

In these three preventions is the key to organic coriander cultivation methods. In addition, the use of vegetable new high-fat film during the three-prevention period can make the plant stems thick, the leaves are thick, the leaves are fresh, the plants are flourishing, and the natural taste is strong. At the same time, it can improve disaster resistance.

Finally, Xiaobian reminds everyone: suffering from bad breath, body odor, severe dental caries, stomach ulcers, sores, eat less coriander, and other coriander warm, measles has been transparent or not exposed to heat and drug stagnation should not be eaten. People who are prone to catch a cold should avoid eating coriander. Because these people often have different degrees of qi deficiency, and the cilantro flavor can be scattered, eat more or eat for a long time, it will consume gas, damage the spirit, and then trigger or aggravate qi deficiency, resulting in a more frequent cold.
