Problems solved by technology

[0004] There are two main restrictive factors in the production of Houttuynia cordata. On the one hand, because Houttuynia cordata is a perennial plant, the growth and development stages are synchronized with the growth of weeds, and weed control has become a difficult problem. Therefore, in the middle and later stages of growth and breeding Weeds are abundant in the field, and manual weeding requires a lot of labor and takes a long time. The use of chemical herbicides is not thorough and the effect is poor. Because Houttuynia cordata is a dicotyledonous plant, herbicides that kill dicotyledonous weeds cannot be used in field production weeding , so it needs to invest a lot of labor and pesticides to control
On the other hand, when the underground stems are harvested every time, a large amount of man-hours and labor are also required for digging the soil, cleaning and harvesting the underground stems, and backfilling the soil; the procedures are complicated and the work efficiency is low.

Embodiment Construction

[0049] In 2012, an ecological cultivation experiment of Houttuynia cordata was carried out in Wulong Village, Beisheng Town, Liuyang, Hunan Province, with a field area of ​​1.0ha; in early spring, that is, in late February 2012, a broad-spectrum herbicide was used in the field once. Glyphosate. Ditch and set up the compartment to level the compartment surface. After 6 days (1 day before transplanting), disinfect the field soil: spray once on the surface of the field with 75% chlorothalonil wettable powder 600-1000 times.

[0050] In 2012, from the end of February to the beginning of June, the rains in Hunan continued for a long time from spring to early summer, and the fields in northern Hunan were severely flooded, especially in low-lying areas, causing local floods. Cultivated with seedling substrate, the effect of drainage and water seepage is good. After the excess rainwater permeates through the substrate, most of it is discharged through the drainage ditch, and there i...

Abstract

The invention discloses an ecological cultivation method for houttuynia cordata and relates to the field of eco-agriculture and crop growing. The cultivation method comprises preparation of land for growing field crops, seed stem disinfection, non-woven geotextile laying, seed stem laying, seedling culture matrix covering and growth management of the land for growing the field crops and the like.The method of enabling non-woven geotextile to serve as the bottom, laying seed stems in the middle and performing seedling culture matrix covering is adopted to the cultivate houttuynia cordata seedstems, the growing environment of rhizomes is optimized, rapid growth of the rhizomes is promoted, so that the rhizomes are high in yield and quality, harm of weeds and soil insects is greatly reduced simultaneously, and environmental pollution caused by farmland pesticide applying is reduced. In addition, the ecological cultivation method further greatly reduces working intensity, saves working hours and effectively reduces production cost.

Description

technical field [0001] The invention relates to the field of houttuynia cultivation, in particular to an ecological cultivation method of houttuynia cordata. Background technique [0002] Houttuynia cordata ( Houttuynia cordata Thunb), which belongs to the genus Hashbaceae, is a perennial herbaceous plant with perennial roots. Houttuynia cordata plants are short and semi-prostrate, and are mainly distributed in the Yangtze River Basin and the south of the Yangtze River. Its growth requires certain habitat conditions; Houttuynia cordata likes a warm and humid environment, and is more shade-tolerant; it mostly grows wild on wet watersides , shady hillsides, low-lying lands, village ridges, ditches and field edges, and grow well in air-permeable sandy loam. Houttuynia cordata is a health-care wild vegetable that can be used both as medicine and food. The whole plant can be used as medicine; It has been widely used in the development of pharmaceutical products and related pre...
