Seedling culture method of wild cordate houttuynia

Abstract

The invention discloses a seedling culture method of wild cordate houttuynia. The seedling culture method includes the following steps of 1, resource management; 2, seed harvesting; 3, sowing, wherein soil is deeply plowed by 20-25 cm, bio-fertilizer is applied according to the standard of 6-7 kg / m<2>, the soil is turned over again, the depth is 10-15 cm, a surface layer is leveled, water is sprayed, and finally sowing is carried out according to the density of 1,000 pieces / m<2>; 4, seedling management, wherein 15-20 days after sowing, a mulching film is adjusted into a small arch rise arched shed, the temperature in the shed is controlled to be 10-18 DEG C, and the relative humidity is 60-70%; 5, management of the growth stage. By means of domestic cultivation with the purpose of collecting seeds, overwintering treatment of seedlings, soil selection, growth space, fertilizer supply, management of the growth stage and the like are studied, the germination rate, the seedling emergency rate and the blooming and fruiting rate of the cordate houttuynia are increased, the quality of the seedlings in the growth process is also good, and volume production can be achieved within a short period.

Description

technical field [0001] The invention belongs to the technical field of seedling raising of Houttuynia cordata, in particular to a seedling raising method of wild Houttuynia cordata. Background technique [0002] Houttuynia cordata is a plant of the genus Trichosanthes, also known as zhe-ergen, scallops, etc. It is a plant with high edible and medicinal value. Houttuynia cordata is often used as an authentic dish in the southwest of my country. It can be eaten cold or stewed. The whole herb can be used as medicine. Houttuynia cordata is widely distributed in the Yangtze River Basin. However, due to human disturbance and destruction, wild high-quality resources are sporadically distributed. In addition, the differences in habitats lead to large differences in seed maturation time, and it is difficult to harvest high-quality resources in batches. The commonly used methods of digging roots for introduction and propagation have a low reproduction coefficient, and the sizes of rh...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a seedling raising method of wild Houttuynia cordata, which can effectively solve the difficulty in harvesting high-quality seeds in the prior art. When the method of root digging is used for introduction and propagation, the reproduction coefficient is low and the quality is poor. The problem that high-quality mass production cannot be carried out in a short period of time
