The soil with loose soil and high fertility is required. The growth cycle of Atractylodes macrocephala Koidz is one year, which actually takes 3 years. Keep the seed for one year, raise seedlings for one year, transplant and grow into a commodity for another year.

(2) Regional distribution of planting Atractylodes macrocephala Koidz.

(3) key points of planting techniques of Atractylodes macrocephala Koidz.

1. Land selection and preparation

Select sunny, cool, good drainage, loose soil, medium fertility of high mountain land or land that has been off for more than 5 years, fertilized, frozen and weathered, leveled before sowing.

2. Planting method

The main results are as follows: (1) seed selection and seedling raising: select large leaf type species with dark green leaves, thick texture, flattened and hypertrophic buds, leave 5-8 full buds in the middle stage, and remove other buds. After the Beginning of Winter, the seeds fully mature, choose a sunny day, cut off the ground part, tie the stalks into bundles, hang in a place of shelter and ventilation, dry for 20-30 days, and then bask in the sun for 2-3 days, collect full seeds, put them in a cloth bag, and hang them in a cool and ventilated place. It is broadcast from late March to early April. Frosts Descent to the Beginning of Winter, the leaves of the seedlings are withered and yellow, choose a sunny day, dig up the rhizome (that is, technical planting), cut off the stem and tail fine roots, remove the diseased and residual plants, spread them out in a cool and ventilated room for 1-2 days, and store them after the epidermis is whitened.

(2) Technical planting storage: choose cool and dry indoor mud ground, spread 5 cm thick 20% water-containing fine sand, put 8-12 cm on top, and then put a layer of fine sand, so stack to 30-40 cm high, and then cover with 4 cm of sand or fine soil. Check every half a month or a month during storage to get rid of diseased plants in time. Before sprouting from December to February of the following year, dig, wash and plant.

(3) Field planting: select delicate epidermis, no diseases and insect pests, full and strong terminal bud, slender upper part, round tail, dense soft fine root, short main root or no main root, technical planting without damage during storage, divided into large and small secondary, respectively, 40-60 kg per mu. Planting, each hole planting 1-2, bud head up, applied calcium scale or cake fertilizer, covered with scorched mud, and finally covered with soil and border flat.

3. Field management of planting Atractylodes macrocephala Koidz

After the seedlings are unearthed, pull up the seedlings between the grasses in time, and when the soil is hardened, ploughing and loosening the soil. Topdressing should be less, which should be applied once in "Lesser Fullness of Grain", "Lesser Heat" and "the Beginning of Autumn" respectively. When the weather is dry, grass is spread between rows to prevent drought; in torrential rain, Atractylodes macrocephala Koidz is afraid of water stains, so it is necessary to dredge the drains so that the rain stops to dry. Field operations such as ploughing and weeding should not be carried out after rain or when the dew is not dry, otherwise it is susceptible to iron leaf disease. The growing period of Atractylodes macrocephala Koidz is long and needs more fertilizer. In addition to applying sufficient basic fertilizer, it is also necessary to apply seedling fertilizer early, re-apply bud fertilizer, and increase the application of phosphorus and potassium fertilizer and organic fertilizer. In addition, attention should be paid to the removal of tillering branches and leaving only one main stem, which is beneficial to the neat shape of the rhizome and avoid bifurcation. Generally from mid-July to early August to support the stem and pick buds.

According to the editor, in recent years, some studies on planting techniques of Atractylodes macrocephala Koidz said that the method of propagation and cultivation of test-tube plantlets can stabilize the stability of regenerated plants, which provides a new way for the rapid propagation of excellent varieties of Atractylodes macrocephala Koidz. With the progress of the times and the updating of technology, it is hoped that the medicine farmers who plant medicinal materials can keep up with the pace of the times and have a high yield and bumper harvest.
