High-yielding cultivation techniques

The dry stem is also known as inch dry, black fan and gold butterfly. It belongs to the iris family and uses rhizome as medicine. It has the functions of heat elimination, detoxification, phlegm-removing, and pharynx. Its rhizomes contain sub-endocrinoids, radioisotopol and other ingredients, which have anti-inflammatory detoxification, anti-viral, diuretic and inhibit cervical cancer cells. The dry shoots are mainly produced in Hubei, Henan, Jiangsu, and Anhui provinces, and Zhejiang, Fujian, Shaanxi, Guizhou, Guangxi, and Guangdong provinces are also distributed.

When the temperature is between 20 and 25°C and the soil moisture is 50%, the seeds start to sprout. When the temperature is 25 to 35°C, the lighting time is long, the soil temperature is high, and the rainfall is sufficient, the shoots grow vigorously; Cold-resistant, it can naturally overwinter in areas with temperatures of -17°C. Shooting does not require strict soil requirements. Plants grow well in sandy loam with high topography, loose fertility, and well-drainage. Soil pH is better with neutral and slightly alkaline. Low-lying rooted stems are perishable.

1. Site preparation

When planting land in a dry and dry place, sandy lands with high topography, sunny reach, deep soil, well-drained land, flat land or gentle slopes should be selected. For example, planting on barren hillsides should be carried out in autumn and winter in the first year of the year to allow it to mature for a period of time, and plowing should be performed once a year to remove tree roots, weeds and stones. Planted with arable land, plowing 1 time before planting, applying 2,000 tons of compost or manure per 667 square meters (1 acre), 25 kg of superphosphate, and 50 kg of cake fertilizer as base fertilizer. Mix, raise the width of 120-130 cm sorghum, or raise the width of 50-60 cm ridge planting.

2. Planting

It can be planted in spring in March or in autumn in November. When planting, in the whole planting surface, plant 25cm by 20cm or 30cm by 20cm, open the hole, deepen the hole by 15cm, apply 0.5kg of soil fertilizer at the bottom of the hole, mix well with the soil, and then mix. Points into the stem 1 to 2 segments, buds upward, or hole planting 1 ~ 2 seedlings, soil compaction, poured into thin human and animal waste water and then cover the leveling surface.

Shooting dry seeds, such as the use of seed, can be broadcast in spring or autumn. Spring sowing takes place in early March and autumn sowing takes place in October. In the entire well-being, press 30cm spacing, 25cm spacing, 6cm depth of the hole, level the bottom of the hole, apply 0.5kg dry manure to each hole, mix well with the soil inside the hole, cover with thick About 2 cm of fine soil. Seeds of 5 to 6 seeds per hole are sown, covered with fine soil after sowing, covered with grass. After the sowing, strengthen the management, often watering to keep the soil moist, in order to facilitate the emergence of seed germination and seedling growth. Seedlings unearthed in a timely manner till the weeding, seedling height of 6 to 10 cm time seedlings, between the weak seedlings, seedlings, leaving strong seedlings, big seedlings, leaving 1 or 2 seedlings per hole. The amount of seed for every 667 square meters is about 5 kg.

3. Weeding and weeding

After the shoot has emerged or survived transplanting, we must diligently cultivate and weed the plant to facilitate plant growth, which is usually carried out 3 to 4 times a year. If it is the first year of spring broadcast, it will be conducted once in May, July and November. The second year will be conducted 3 times, in March, June and November respectively. No more cultivating and weeding after sealing the line. In addition, after the plants are dried in November each year, they combine the cultivating and weeding soil once and then use the fine soil in the ditch to cultivate around the rhizosphere to facilitate the wintering of the plants and prevent lodging.

4. Dressing

Shooting is a hi-fat plant. In addition to applying base fertilizer, it is top-dressed once in spring, summer, autumn and winter in the second year. In the spring and summer, topdressing, every 667 square meters of planted manure water 1500 kg or urea 25 to 30 kg, 10 cm outside the plant open hole. Every 667 square meters of applied fertilizer in autumn, 1500 to 2000 kilograms of mixed fertilizer of grass and wood ash, compound fertilizer 25 kilograms, after the application of soil. For each 667 square meters of winter, 1500 kg of mature manure, 20 kg of plant ash, 25 kg of superphosphate, and 30 kg of compound fertilizer are applied. After mixing, the soil is applied. The first two top dressings can promote the growth of stems and leaves, and the second top dressing can promote root growth and increase yield.

5. Drainage irrigation

Shoot dry and afraid of water swill, after the heavy rain to dig trenches, remove the water in the ground to prevent root rot. Although dry shoots are drought-tolerant, they should be kept moist after seedling and transplanting to facilitate seedling growth. If drought occurs during the seedling stage, it should be properly watered or irrigated. After 10 cm in seedling height, little or no irrigation can be done.

6. Picking buds

Planted with rhizomes can be flowered in the year; seedlings transplanted or broadcast live, they will not bloom until the following year, and they have long flowering periods and many flowering results. They consume large amounts of nutrients and affect root growth. In addition to leaving the planting sites, the buds should be picked up on sunny days and morning dew when the plants are convulsed. The buds should be removed and removed in batches.
