How is the root grown? If you want to plant the root of the banlange, is it difficult to plant the r

Cultivation technique of indigo root.

1. Overview. Also known as big green root, woad, songqing. The biennial herbaceous plant of the cruciferous family is called the root of the blue with the root of the medicine, and the big green leaf is called the big green leaf with the root of the medicine.

The height of the plant is 40-90 cm. The flowering period is in May, and the fruiting period is June. It has the function of clearing away heat and detoxifying, cooling blood and eliminating spots.

It is mainly used for the treatment of epidemic disease, mumps, Japanese encephalitis, acute infection, sore throat and other symptoms. It is widely introduced and cultivated throughout the country.

2. Growth characteristics.

It has strong adaptability, and the requirements for the natural environment and soil are not strict, and it can generally adapt to the soil with pH value. It is more cold-tolerant and can be cultivated in all parts of the north and south of China.

3. Cultivation technology.

Turn more than 30 cm deep to make the roots straight, smooth and not forked. The seeds are live, and the spring sowing is in mid to late April around the time of the valley rains. Ditch according to the row spacing of 20-25 cm, about cm deep, sprinkle the seeds evenly into the shallow ditch, cover with soil 1 cm, and slightly suppress.

4. Field management.

1. Cultivating and weeding; 2. Seedlings and seedlings should be set according to the plant spacing of 8-10 cm; 3. Top dressing, nitrogen fertilizer in the early stage, phosphate fertilizer in the later stage; 4. In case of spring drought, it should be watered thoroughly in time. Pay attention to drainage to prevent root rot.

5. Pest control.

1) Downy mildew mainly harms the leaves, producing white or gray-white mold on the back of the leaves, the disease is not obvious, and the serious ones can make the leaves yellow. Control method: burn the diseased and residual plants after harvest to reduce the overwintering bacteria.

Before and at the beginning of the disease, spray with 50% antibacterial special 1000 times liquid or 65% zebsen wettable powder 500 times liquid liquid for prevention and control, pay attention to ventilation, light transmission and drainage. (2) The larvae of the cabbage butterfly and the diamondback moth damage the leaves, eat the leaves into holes and missing carvings, and only the leaf veins are left in serious cases. Prevention and control methods:

After the roots are harvested, the shoots are burned intensively, and the larvae are sprayed with 800 times of 90 trichlorfon or 500 800 times of 2 5% rotenic essence emulsifiable concentrate. Aphids: Spray with 200x dimethoate liquid.

6. Harvesting and processing.

Spring sowing can harvest large green leaves 2-3 times a year, can cut the outer layer of leaves, leaving the heart of the leaves. or 5 cm above the ground. Harvest in early to mid-October.

It is not difficult, you must find a professional person for advice, to ensure the fertility of the soil, to spray pesticides in time, to carry out pest control, but also to ventilate in time, to control the density of planting.

It's not very difficult, but if you want to plant it well, you must learn more about the living habits of the root of Banlangen, so that you can plant it well.

It is not difficult, you can buy some books about the technology of planting inline root, and you can also check the information on the Internet, so that you can plant it well.

1. Planting time.

There are many times to plant indigo roots, which can be selected in early spring, spring, summer, autumn and other seasons. However, in order to increase yields, it is best to plant in the spring, usually in an area where the temperature can be maintained at 12 °C. In the south, it could be slightly earlier, and in the north, it should be postponed so that it could be done in April.

2. Planting method.

1. Soil selection: When planting the roots of the blue, most of them are planted in a large area, and the soil should be selected first, and it is best to use relatively loose and well-drained soil. In addition, some farm manure should be added to the soil.

2. Germination: Prepare a pot of clean warm water, put the relatively full seeds into it and soak it for at least 4 hours to make its shell soft. After removing the seeds, they need to be dried, and there should be no impurities in the seeds.

3. Planting: Sow the seeds into the prepared soil, and then cover it with a layer of 1cm of soil on the seeds. It needs water to grow, so it should be watered properly, but there must be no stagnant water, and finally wait for it to emerge.

Find a piece of soil, plant the roots in the soil, and then bury the seeds of the roots, remember to water them, and then add fertilizer.

Choose a fertile, loose soil, then sow the seedlings, remove the grass in the middle of the year, fertilize it, and water it, and you're good to go.

This plant is sown from seeds, which are sown in the soil and managed well.

Suitable seeds are selected, seedlings are raised, weeds are removed from the soil, and then planted by hand, and regular management is carried out after planting.

Cultivation of the root of the Radix indigo.

1. Land selection and land preparation.

It is a deep-rooted medicinal plant with a taproot length of up to 40 to 50 cm, so it should be planted in sandy loam soil or river alluvial soil with low water table, good drainage, loose and fertile soil. Sandy, sticky, low-lying land grows poorly and is easy to fork. Banlan root is a kind of fertilizer-loving, fertilizer-tolerant plant, so 4000 kg of rotting manure per mu, 50 kg of superphosphate, 30 kg of potassium sulfate, 20 kg of urea, apply plantar fertilizer, 30 cm deep, plough fine rake flat, break the soil and cover the block, and then make a furrow, the north should be a flat furrow, the south can be a high furrow, easy to drain, the furrow is wide meters, the furrow is 20 cm high, the width of the operation road is 30 cm, and the drainage ditch is made around.

2. Sow seeds. Spring sowing and summer sowing are available. Spring sowing is in March and April, and summer is sown in May and June.

Before sowing, the seeds are treated, soaked in warm water at 40 degrees for 24 hours, fished out, dried on the surface, and can be sown, so that the seedlings can be full and the seedlings are complete, and the seedlings can emerge in 7 10 days, and the weight per mu is kilograms.

On the prepared furrow surface according to the row spacing of 30 cm, the depth of the ditch is 3 cm, the seeds are evenly sprinkled in the ditch, covered with soil centimeters, and slightly suppressed. (ditching can be used with three legs of wheat columbian ditch or with two legs of small claw hook ditch), early spring sowing, can be covered with mulch, is conducive to the early emergence of the root and improve the yield.

3. Field management.

1) Cultivating and weeding, thinning seedlings, and setting seedlings.

After sowing, it is necessary to pay attention to the observation that 70% of the seedlings covered with plastic film can be uncovered and shallow hoeing can be carried out to remove small weeds. When the seedling height is 3 5 cm, the seedlings are thinned, the small seedlings and weak seedlings are eliminated, and the strong seedlings are left, and the seedling spacing is 4 6 cm; When the seedling height is 7 10 cm, the seedling spacing is 8 10 cm. When the seedling spacing is too dense, the roots are small and the leaves are not thick; The seedling spacing is too large, the taproot is easy to fork, the fibrous roots are many, the strips are not straight, and the yield is reduced.

2) Top dressing, drainage and irrigation.

After the seedlings are set, according to the growth of the root of the banlange, human feces or inorganic fertilizer can be applied once. Every time you cut the large green leaves, you should pay attention to reapplying manure to promote the later growth of the heel and increase the yield. Foliar fertilizer can be sprayed, with potassium dihydrogen phosphate as well, sprayed 2 3 times in the middle and late stages of growth.

Pay attention to watering in drought to facilitate the normal growth of the root of the banyan root, which can be carried out in the morning and evening every day, and remember to do it under sun exposure. Pay attention to drainage in the rainy season, long-term water accumulation, the root of the banyan is easy to rot the root, resulting in a reduction in yield.

<> choose to plant the roots of Banlan in the fertile soil and well-drained plots, apply fermented farmhouse fertilizer as the base fertilizer before planting, and soak the seeds in warm water for 4 hours after removing the impurities to reduce the incidence of pests and diseases. Early April or late May to early June is suitable for planting indigo roots, 5-7 days can germinate, seedlings height of 7-8 cm and 10-12 cm, respectively, a seedling, to the weak and strong, lack of seedlings to make up, pay attention to fertilizer and water management in the later stage.

1. Site selection and seed selection

1. The adaptability of the root is relatively strong, with the characteristics of high temperature resistance and cold resistance, and it is generally selected to plant in the plot with fertile soil, loose, breathable and good drainage, and the terrain should be flat or slightly high, so as to avoid choosing low-lying plots for planting, and also have good irrigation conditions.

2. Before planting, use fermented farmhouse fertilizer as base fertilizer, and apply 1500-2000 kg of fermented pig manure, cow manure, sheep manure, horse manure, etc., 50 kg of superphosphate, and 100 kg of plant ash per mu, and then turn it deeply, turn the fertilizer into the soil, and then rake it flat.

3. Choose healthy seeds for planting, remove seed impurities and soak them in warm water for 3-4 hours, which can kill the pathogenic bacteria on the seeds, reduce the probability of pests and diseases in the roots, and dry the seeds after soaking.

Second, sowing seedlings

1. Planting indigo root is generally sown in spring and summer, spring sowing is generally in early April, summer sowing is in late May to early June, about 2 kg of seeds are used per mu, the seeds are evenly sown in the soil, and then gently covered with the soil layer to keep the soil moisture at about 65%, and germination can occur in 5-7 days.

2. When the seedling height is 7-8 cm, the seedling is determined according to the plant spacing of 6-10 cm, and the weak and strong are left, and the lack of seedlings is filled. When the seedling height is 10-12 cm, combined with cultivating and weeding, the seedling is set according to the plant spacing of 6-9 cm and the row spacing is 10-15 cm.

3. Cultivating and weeding

After the seedlings are ready, they should be cultivated and weeded, clean up the weeds in the field, avoid competing for nutrients with the seedlings, and weed every 10-15 days.

Fourth, fertilizer and water management

During the period of cultivation and weeding, 1500-2000 kg of human manure or livestock manure per mu is topdressed. Watering once every 3-5 days during the seedling stage of Banlangen root to keep the soil moist and conducive to the growth of seedlings, watering less or no watering after sealing the ridge. If the weather is dry after summer sowing, it needs to be watered in time, and if it is rainy, it is necessary to open a ditch in time to drain it to prevent water accumulation in the soil.
