Dodder beans are aliased to bean parasitic, rootless grass, non-ginseng vine, yellow silk, old crow silk, and yellow silk vine. It is a genus of the genus Cuscuta of the family Convolvulaceae. It has a 1-year-old twining parasitic herb with no leaves. Its stem length can be up to about 1 meter. It is elongated and sprawling, and it has many yellow pigments that extend into the host plant to absorb nutrients for its growth. Corolla yellow-brown, with subtle engraved surface roughness, grain size such as tobacco seeds. In recent years, the demand for dodder silk as a medicinal material and a health care product is increasing, wild resources cannot meet the needs, and a large area of ​​artificial planting is urgently needed. This year, we have carried out artificial cultivation according to the needs of drug dealers. Now we will introduce the basic conditions and planting techniques of Cuscuta below, for reference. First, the role of Cuscuta and species Cuscuta is a parasitic plant, with seeds as medicine, mainly nourishing the liver and kidney, Yishuang eyesight, antidiarrheal and so on. Indications Yaoxisuanruan, impotence, leakage, urinary frequency, dizziness, vision loss, fetal movement disturbed, threatened abortion and lower blood pressure. There are three kinds of Cuscuta in China: Cuscuta chinensis, Europe (Southern) Cuscuta, and single column (Core and Female) Cuscuta. Different types of host plants are different. There are 23 species and 74 species of herbaceous plants in Chinese dodder, and 3 families and 3 species of woody plants. There are 6 species of European dodder herb. There are 13 species of woody and 10 species of herbs in the single-column dodder. Dodder parasitic plants are widespread and distributed throughout the country. The Cuscuta we planted is the European Cuscuta, also known as the Southern Cuscuta. The main parasitic plant is oil flax. The northern farmers call it Husk Dodder and flax together for planting and harvesting. It is suitable for large-scale planting. Second, dodder artificial cultivation technology Cuscuta breeding period of about 100 days, with the same species of parasitic plants received, the specific cultivation methods are as follows. 1. Neutral sandy soils should be selected from argillaceous soil and chernozem, with loose soil, fertile soil and good drainage. Before planting, apply organic manure 2 to 3 tons per 667 meters or compound fertilizer 6 to 8 kilograms and urea 3 to 5 kilograms. Deeply apply into the soil. Strictly site preparation to achieve "qi, flat, pine, crushed, net, earthworms" six Word standard. 2. Pre-seeding seed treatment Before sowing, firstly select the flax seeds from 2 to 7 kilograms per 667 meters, and mix 25% carbendazim seed from 4 to 5 or 70% thiophanate-2 to 3 , Add phoxim 1 to the wet mix, heap stuffy 5 to 6 hours dry to be broadcast, can prevent blight and underground pests. 3, seeding dodder seed every 667 m 2 with the amount of 0.5 to 0.7 kg, and flax seeds every 667 meters 26 to 7 kg fully mix, with 24 rows of seeders, with fertilizer compound fertilizer 3 kg, urea 1 kg sowing. When planting with a roller, sowing before sowing, suppression, sowing depth of 2 to 3 cm, should not affect the emergence of too deep. The emergence of flax is fast, generally stable in the ground temperature above 8 ~ 10 °C, 4 ~ 5 days of emergence, and dodder seedlings later than the emergence of flax 15 days. 4. Management Cuscuta in the soil moisture is good, the temperature is faster than the seedlings, young shoots emerged as pale yellow, fine as silk, 3 to 5 days began to entangle the host, the underground part of the gradual death, rely on parasitic nutrition, so management must pay attention The following points. 1 chemical weeding before the emergence of dodder can be removed, control broadleaf weeds, with dimethyl tetrazolium 100 ~ 120 ml / 667 m 2, plus 2,4-D vinegar 8 ~ 10 g ml / 667 m 2 10 to 15 kg of foliar spray on water. For grass weeds such as green foxtail and wild oats, it can be used in the period of 3 to 5 leaves of Ganoderma lucidum to 25 to 30 ml/667 m2, Weishuang 60 to 70 mg/667 m2, and oximec and chloramphenicol. Control. After the emergence of Cuscuta, the dicotyledonous weeds in the field have to be manually removed and the grass weeds can be removed. 2 watering Humao generally poured 1 to 2 water, a water for June 5 to 10, two water for July 1 to 5 days. Dioshui is a grouting water and should be poured on sunny days without wind to prevent lodging. 3 foliar dressing in flax flowering to grain filling stage foliar topdressing Shi Bao, potassium dihydrogen phosphate, efficient leaf fertilizer and other foliar fertilizer 1 or 2 times. 5, harvest a large area harvested with Kangbyin machinery, reduce the height of Kangbyin, low-cut harvest, to minimize waste. A small area is manually harvested and rolled, and the finely-divided seeds of the flax can be sieved out and dried to be sold. III. Economic Benefit Analysis From 2000 to 2001, two years of artificial planting of Cuscuta seedlings can receive 30 to 40 kilograms per 667 meters. The current market price is 8 yuan per kilogram, which can be 240 to 320 yuan, and the flaxseed can receive 60 per 667 meters. ~ 80 kg, 2.4 yuan per kilogram, income of 144 to 192 yuan, total gross income of 384 to 512 yuan. 4 yuan, gross income 240 to 280 yuan. Single planting flax, yield per unit of 667 m 2 100 to 120 kg, 2.4 yuan per kilogram, gross income of 240 to 280 yuan. Both compared to flax seed intercropping dormant 667 m 2 increased income of 144 to 232 yuan, deducting seed dodder Cost 30 yuan / 667 m 2, the actual net income increased by 114 to 202 yuan. Dodder seed medicine is convenient for planting and management, and it should be planted on a large area and easily accepted by farmers. Fourth, note the post-poor vegetables and fiber linen can not be planted Dodder, after the emergence of dodder, broad-leaved weeds can not be removed. Although dodder seed is a medicinal material, it must be sold on a contract basis and contracted.
