Ecological cultivation method for houttuynia cordata

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...

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.
