The cultivation technique of health vegetable chicory

Chicory rarely causes pests and diseases during the cultivation process. Almost no pesticides are applied during the cultivation process of roots. In the softening cultivation process, no pesticides and fertilizers are used, and food is safe. It is a true green food and is listed as a 21st century. Health vegetables.
First, seed cultivation
1. Site Preparation Fertilizers The roots of chicory grow underground. Each root can be as long as 30 cm and 5 cm thick. In order to facilitate the growth of seedlings, the land must be deep-turned 25 to 30 centimeters before planting. Then apply basic fertilizer to the sowing line. Apply 5 cubic meters of high-quality farmyard fertilizer per 667 square meters (1 mu). 100 kg, potassium sulfate 25 kg.
2. Seed sowing chicory sowing is too easy to twitch, sowing late growth time is short, is not conducive to the expansion of the roots, generally in early August sowing (but there are also individual plants convulsions, to be promptly removed), chicory seeds are small, live every 667 Use 200 grams square meters, seedlings can save a part of the seed, but the seedlings transplanting must ensure that the seedlings transplanted, more than 6 leaves rearing cultivated seedlings is not straight root, but was chicken-like, with many points Branches are not conducive to softening cultivation.
3. Field management (1) Watering in time after sowing, watering from the small ditch between the two rakes to penetrate the soil of the sowing line, it is not absolutely necessary not to sow the line, otherwise it is difficult to emerge. Generally 3 days after sowing, the seedlings can be emerged. The seedlings should be timely watered to keep the soil moist. The seedlings are found to be transplanted from the seedlings in a timely manner. After 6 leaves, the seedlings should not be transferred.
(2) Chicory has strong vitality. The seedlings are very strong in the second half of the planting period. They can be combined with cultivators and weeds, with a spacing of 20 cm, 9,000 667 m2 per 667 m2, combined with watering after seedlings, and urea per 667 m2. 10 kg, no longer topdressing nitrogen fertilizer.
(3) In the middle of October, it will enter a period of prosperous growth. At this time, special attention should be paid to remove the convulsing plants in time and, in combination with watering, topdressing 10 kg of potassium sulfate per 667 m2.
4. The roots of chicory harvested are very cold-tolerant and can still grow through light frost. Before freezing, the chiral root will be concentrated by humans. Try not to cut the leaves. Cut the leaves 1 cm away from the growing point. Roots are stacked in 10 cm thick and dried for 3 days. They are covered with grasshoppers at night and covered with plastic film in the event of rain or snow.
5. Storage of roots Place the sun-dried roots in a breathable woven bag. In the ground, 1.5 meters wide, 80 cm deep, and an unlimited length of ditch, the woven bag of chicory root will be placed in the ditch. It can be placed in two layers, buried in soil, and made into a bow shape to prevent snow from seeping. Every 2 meters in the middle of the ditch with corn stalks to make an eye.
Second, the softening cultivation of chicory Soften cultivation of chicory refers to the chicory root in the dark, moisture, ensure the temperature conditions, the use of seedlings of their own nutrient growth to form the process of leaf ball (with garlic garlic).
1. Treatment of roots The roots of the chicory roots are cut off with a knife, and the small buds of the leaf base are also cut off, leaving only the center of a main bud, which is conducive to the formation of a single large chicory Leaf ball.
2. The cultivation of roots is done in a greenhouse. 1.5-meter-wide rakes are made between north and south, and the soil is deep-turned 35 centimeters deep. The surface is flattened and irrigated. The chicory is sown in the mud at a spacing of 5 centimeters. Point slightly higher than the ground, and then make a small bow shed, cover the shed with a double black plastic film to ensure dark inside the shed. When growing in shelters, basements or indoors, chicory roots can be buried with sand. The buds are a little higher than the sand surface. The rows are 5 centimeters apart and are irrigated to ensure the interior is dark.
3. Softening period management Softening cultivation can be carried out at a temperature of 2-25 degrees Celsius, but the temperature is low for a long period of time, and the temperature is high and fast and the quality is poor. The optimum temperature is between 18 and 20 degrees Celsius. The chicory that grows is of good quality and has a growth cycle of about 20 days. The softening of the chicory is to be sown and a batch of seeds sown every day. This way, chicory is sold every day after 20 days. After harvesting, sowing seeds and roots will not only ensure the supply of goods, but also will not cause product backlog, but also make full use of the cultivation site.
In order to increase the temperature, it is possible to directly heat the fire in a greenhouse, basement or room for softening, but care must be taken to prevent the coal ash from falling on chicory leaves. Increase ventilation to discharge the gas generated from the stove. Ventilation shelters or basements can be equipped with ventilation fans. Ventilation is best done at noon to prevent significant cooling by ventilation.
4. The harvested chicory balls will be harvested when they grow to 20 centimeters in length and each weighs 250 grams. With a knife, it can be cut at the bud, and it can be sold, and the underground roots can be cut out to allow the next cultivation. The advantage of this harvesting is that the goods are beautiful in appearance, easy to handle, and labor-saving; the disadvantage is that many nutrients are not used on the roots, and they are wasted.

Another way is to wait until the chicory ball grows. When the leaves around the shootball grow to about 15 centimeters, these leaves are plucked down, along with the long pods, until the nutrients in the roots are exhausted. This advantage is the ability to make full use of the roots of the nutrients; the disadvantage is that many workers, the appearance of the goods is not beautiful, a long time to occupy.
