Seed price and planting method of dodder

Dodder, also known as bean parasitism, rootless grass, yellow silk, etc., is an annual parasitic plant of the genus Cuscuta of the Convolvulaceae. Harmful weeds in soybean producing areas are also harmful to crops such as flax, Ramie, peanuts and potatoes. Seed medicine has the effects of tonifying the liver and kidney, tonifying essence, strengthening yang and stopping diarrhea. Let's take a look at the seed price and planting method of dodder.

How much is dodder seed per jin?

The price of dodder seeds is about 50-60 yuan per jin, but it varies according to the quality, variety, producing area and market of the seeds. Dodder likes high temperature and humid climate, has lax requirements on soil and strong adaptability. Wild dodder is commonly found in plains, wastelands, graves, borders, legumes, Compositae, families, dipping families and other plants, and is most likely to be parasitized on legumes to propagate and spread by seeds.

The sowing method of dodder

1. Seed collection: dodder is collected in time in mid or late October before the capsule is ripe and cracked, dried, threshed and put into a cloth bag and hung under the eaves to avoid rain and sun. Because dodder must undergo a low temperature in winter in order to sprout and grow normally.

2. Soil preparation and fertilization: dodder has no special requirements for soil, as long as it is suitable for planting soybeans. When sowing soybeans, it is necessary to apply sufficient basic fertilizer, generally using 50 kg of superphosphate, 10 kg of urea and some organic fertilizers per mu.

3. Sowing method: soybean is the best host of dodder, followed by broad-leaf weeds such as sesbania, sowing before emergence after sowing, sowing with 20 grams of dodder seeds and 2 kilograms of dry fine soil per mu, brushing soil with a broom to cover the seeds, or not covering the seeds.

Planting method of dodder

1. Rational fertilization: the cultivation of dodder should do a good job of fertilization, applying 15kg of nitrogen fertilizer, 20kg of phosphate fertilizer and 10kg of fertilizer per mu, and less base fertilizer in fertile plots, so that both host and dodder can be taken into account.

2. Growth control: dodder spreads very quickly, and the host slows down or stops its growth due to the loss of a lot of water and nutrients, so it is necessary to control the excessive growth of dodder to prevent the host from dying prematurely.

3. Intermediate ploughing and weeding: after soybean emergence, one intertillage weeding should be carried out, shallow ploughing should be done to avoid root damage, weeds should be removed during the growing period, and the times of weeding can be reduced or no weeding can be done after winding bean plants, and there is no need to use herbicides.

4. Timely harvest: the harvest time of dodder is before soybean, when the capsule has more than 50% blackening, more than 30% yellowing, 10% green turning yellow, small area harvest can be pulled up manually and concentrated threshing, and large area harvest can use rice and wheat harvester.

5. Cultivation in the following year: dodder will no longer be planted in the following crops. Aquatic crops such as rice should be planted as far as possible in places with fresh water irrigation, and Gramineae crops such as corn and sorghum should be planted in arid areas.
