A New Technique of Belamcanda chinensis Planting

Shegan alias golden pole, butterfly, Hemerocallis, for Iridaceae herbs, mostly wild. It has the functions of clearing heat and detoxification, reducing qi and expectoration, dispersing blood and detumescence. It is mainly used to treat influenza. Shegan is not only used in medicine, but also a precious flower, which is an export product of foreign trade. In recent years, due to excessive mining, resources have become increasingly scarce. Therefore, the development of shoot dry production is a good way for farmers to get rid of poverty. Generally, the yield of dry medicine per mu can reach 200 Mu 250 kg.

1. Land selection and land preparation

In general, it can be planted in mountainous and flat land, but it is not suitable to be planted in the soil where clay is too heavy, flooded land and saline-alkali land are too heavy. When preparing the soil, plough 17 centimeters deep and flatten the bed. Apply 2000-3000 kg per mu of base fertilizer or compost and 25kg-30kg of superphosphate. Can also use human feces and urine, plant ash and other farm manure as base fertilizer.

2. Methods of reproduction

The main results are as follows: (1) in seed propagation, dried seeds begin to germinate at 8: 14 ℃, and the germination rate decreases significantly when the temperature is as high as 30 ℃. The emergence of seedlings is slow and irregular, and the duration is as long as 40-50 days. The germination rate of seeds stored in wet sand is high, the germination rate of sun-dried seeds is low (only 45%-50%) and slow, and the duration is longer. After applying basic fertilizer, the seedling land is leveled for bed, and the sowing time is suitable for spring and autumn (when the temperature is suitable for seedling emergence). In spring, the seeds were sown in the border in late March, covered with 5 cm of soil, watered after a little suppression, and seedlings emerged about 2 weeks later. The sowing rate is 10 kg per mu of seedling land, which can be transplanted to 7 mu in the field. If you plant 1 mu of land, you will use 2-2.5 kg of seed. Before the ground was frozen in autumn, the sowing method was the same as above, the seedlings emerged in the early April of the next spring, the seedling bed management was simple, watering 2-3 times, and weeding frequently. It was planted in May and June of the year when the height of the seedling was about 6 cm, and it was planted in the field with a distance of 45 cm to 60 cm. And then pour water. The survival rate is as high as 95%. The seed propagation coefficient is high and the plant growth is robust.

(2) there are dozens of rhizomes in rhizome propagation, which has strong vitality, so it can be propagated by rhizome. The planting period is generally carried out before turning green, and the seedlings are split according to the natural growth shape, and each rhizome needs to have 2 buds. When planted, the buds are facing up. If the bud is white, it can be buried in the soil, and if the bud has turned green, it can be exposed to the ground. The distance between rows and plants is the same as above. The trench is 15 cm deep. If the fibrous root is too long, it can be cut to about 5 cm. Press the cover soil tightly, then water it.

3. Field management

The main results are as follows: (1) cultivated soil should be weeded and loosened frequently in spring, no weeding and loosening soil should be removed after ridge closure in June, and soil should be cultivated in the rhizosphere to prevent lodging.

(2) in the second year of topdressing, ditches were opened between rows in early spring, 2000 kg of soil and miscellaneous fertilizer per mu, or 700kg of human feces and urine, plus 15kg / 20kg of superphosphate as topdressing.

(3) although watering Shegan likes drought and tolerance to severe cold, it needs watering at seedling emergence stage and Dingmiaolang. Keep the field moist, and the seedlings can be watered when they are as high as 10 centimeters. Attention should be paid to drainage in the rainy season to prevent stagnant water in the field from causing rotten roots.

(4) the shoot stem propagated by picking flower seeds will blossom and bear fruit in the following year. The year of rhizome propagation blossoms and bears fruit. The flowering period is long, and there are many blossoms and fruits. Pick flowers 2 or 3 times during bolting in unseeded plots to facilitate rhizome growth.

4. Pest control

Shegan is prone to rust, which is caused by a kind of aspergillus in fungi, which is often harmful in autumn, and the leaves show brown raised rust spots. The adult plant occurs early and the seedling occurs late. Prevention and treatment: at the initial stage of the disease, 95% sodium rust 400 times solution was sprayed once every 7-10 days, continuously spraying 2 times 3 times. Insect pests are grubs, mole crickets, etc., can be killed with poison bait.

5. Harvest and processing

The shoot stem was harvested by Cold Dew after 2 years of growth (it takes 2 years for seed propagation and only 1 year for rhizome propagation). Remove the stem and neck root from the planed root, wash it and dry it, and then sell it.
