Niu Zizi, alias Niu Zi, Dao Zi and so on. The fruit is used medicinally, and has the function of dispelling wind and cooling, expelling lung rash, dispersing and detoxifying, protecting the liver and suppressing cancer, and reducing blood sugar and removing fat.
First, the land preparation site has a high topography and good drainage. Combined with site preparation, sufficient base fertilizers: Mushi farmyard fertilizer 3000 kg, urea 20 kg or NPK fertilizer 50 kg. Then use a tiller to flatten and wait for sowing.
Second, sowing and sowing time and flax same or slightly later, from the rain to the beginning of summer is more appropriate. It can be transplanted with seedlings, interplanted or broadcast in various modes.
When the seedlings are raised, shallow grooves with a spacing of 25-30 cm wide are opened on the entire surface of the seedlings, and the seeds are evenly sprinkled into the grooves to spread the density to 10-15 grains/meter. Cover soil can be flat. It can also be broadcast. The seeding rate per acre is 1.5-3 kg. After the burdock seedlings are released, they should promptly press the 18-20 cm spacing between the seedlings to strengthen the water and fertilizer management in the field and promote its rapid growth. And before the end of the autumn soil, the seedlings will be transplanted in time. In the mountainous area, the planting distance is 10070 cm, and in the Sichuan, the planting distance is 10090 cm. Fill soil compaction to facilitate survival. After transplanting, a 70-120 cm black mulch can be applied to the planting ridges. Can also be transplanted after the first film.
Third, the field management of autumn transplanting can be fertilizer in the spring of the second year after the current leaves (dressing point should be 15-20 cm away from the plant to prevent burning seedlings). And cover the mouth with fertilizer and the emergence of the mouth. After Qimiao pay attention to cultivator weeding. In the winter and spring time, the base fertilizer was chased once, and 20 kg of urea and 7.5 kg of diammonium were applied per acre. Before the flowering moss was combined with aphids to control spraying 20ppm paclobutrazol + 800 times anti-inverse or 1000 times imidacloprid once to facilitate branching and flowering. After the flowering period, the beetle combined with 0.3% of potassium dihydrogen phosphate and 1000 times of water and phosphoramidite was sprayed to control the production of the beetle.
Diseases and Pest Control The major pests and diseases of Arctium lappa are black spot disease, which can be prevented and treated with 1:1:120 Bordeaux before the onset of disease. The main pests are locusts and red spiders, which can be used to prevent and control insects. Underground pests are controlled with phoxim.
V. Harvesting and processing After the autumn, most of the fruits are yellowed and the whole plant is harvested. The harvested fruit is dried inwards and piled outwards in an annular shape. The hose is used to spray water and the waste plastic cloth is used for 3-4 days. After the fruits and fruit branches are separated from each other, the stems are collected and piled up in the open air until the ears are dark, and the fruits can be collected with a thresher. Generally, the interplanting yield per mu is between 200-250 kg; 150-200 kg of open-air mountainous areas are visible; and the mulching of the mulching film is not very different. The yield is between 250-350 kg and the highest is 400 kg.
