High-yield planting method of traditional-Chinese-medicine semen cuscutae

Abstract

The invention discloses a high-yield planting method of traditional-Chinese-medicine semen cuscutae. The high-yield planting method disclosed by the invention has the beneficial effects that by adoption of a selective seeding technology, the premature senility of host soybeans, even death, is avoided, the production output values of the semen cuscutae and hosts are increased and the comprehensivebenefit is improved; flat seeding and sole cropping of the hosts are adopted for parasitism of medicinal semen cuscutae and a wide-narrow row planting technology is adopted, so that the ventilating and light-transmitting space of the host soybeans is enlarged, the edge effect of the host is obvious, the light-energy utilization rate is increased, the fruiting rate of the medicinal semen cuscutae is increased and the comprehensive benefit is improved; a three-dimensional composite planting technology is adopted, the symbiotic period among the crops is short, the host soybeans have sufficient growth space and independent growth time in spite of hosting of the semen cuscutae, and then due to local excellent light-heat conditions, water and fertilizer conditions and field-management technicalmeasures and the like, not only can wheat, watermelons and soybeans be harvested, but also the dry seeds of the semen cuscutae can be harvested; not only are excellent natural resources such as light,heat, water, fertilizer utilized fully, but also the land utilization rate is increased, the soil fertility is improved and the economic income of farmers is increased.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a high-yield planting method of Chinese medicinal material Cuscuta. Background technique [0002] Medicinal dodder is an annual entwining parasitic herb that lives by absorbing nutrients from the host. It cannot be cultivated alone. It must be planted in advance with parasitic crops in order to obtain better seed yield. [0003] In recent years, medicinal dodder has a large demand as a medicinal material and health care product, and wild resources cannot meet the demand, so artificial cultivation is urgently needed. Medicinal dodder has changed from natural growth to artificial cultivation, and it grows symbiotically with its main host soybean, with a growth period of about 100 days. Generally, 40~50kg / 666.7m of dry seeds can be obtained 2 , high yield up to 75~100kg / 666.7m 2 . With the gradual maturity and improvement of artificial cultivation techniques and the effective use o...

Problems solved by technology

[0007] At present, in order to harvest more dodder grains and obtain higher economic income in the production process of Chinese herbal medicinal dodder, the planting technology is not in place and not standardized, the sowing amount of dodder is too large, the sowing date is random, and the host The sowing amount of soybeans is large and the planting density is high, resulting in thin and lodging host soybean stalks. Cuscuta parasitizes spring soybeans and causes premature aging or even death of the host. The yield of dodder and soybeans is low. Generally, the dry seed yield of dodder is 20kg / 666.7m 2 Around, soybean yield 20~30kg / 666.7 / m 2 , there is even no meaning of harvesting, the comprehensive benefit is low, and the coordination of dodder and host to increase production and efficiency is greatly limited
