Physical weeding method of bletilla striata

Abstract

The invention relates to the technical field of planting and weeding of bletilla striata, and particularly relates to a physical weeding method of the bletilla striata. By the step of carrying out foundation deep-plowing, ditching, filling and river sand coverage in July to December, a porosity of an integral foundation is improved, and the foundation is guaranteed to be in a fluffy state for long time, so that oxygen can be effectively provided in the bletilla striata growing process and rapid growth of the bletilla striata is promoted; selection of fillers in a ditch is combined and limitations to a coverage thickness of river sand and a distance from coverage to the center of a bletilla striata nest are combined, so that the fillers can effectively take heat preservation and moisturizing effects on the foundation, block rapid growth of weeds, and cannot influence growth of the bletilla striata, and thus, the aim of completely weeding can be fulfilled, the fillers also can be fermented in the foundation, the temperature of the bletilla striata in the overwintering period is guaranteed, rapid emergence and growth of the bletilla striata in the next year are promoted, yield of the bletilla striata is improved, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of bletilla striata planting and weeding, in particular to a method for physically weeding bletilla striata. Background technique [0002] Baiji, (scientific name: Bletilla striata) also known as Lianjicao, Gangen, Baiji, Ruolan, Zhulan, Zilan, Zihui, Lily. It is a perennial herbaceous bulbous plant (root tuber), with a plant height of 18-60 cm. Mainly distributed in China, Japan and northern Myanmar. The main flowering period is in spring, but depending on the climate of various places, it may bloom from late winter to early summer. Bletilla striata has a wide range of medicinal value and garden value. Mainly used for astringent hemostasis, detumescence and granulation promoting. The flowers have purple, white, blue, yellow and pink colors, and can be potted indoors for viewing, or decorated in a relatively shaded flower bed, flower border or corner of a courtyard. [0003] In the traditional Bletilla ...

Problems solved by technology

This makes the technical requirements of bletilla striata weeding higher than other common plants, so the labor cost is also higher than other crops

Weeding of bletilla striata has become the main cost of bletilla striata cultivation, seriously affecting the economic and social benefits of bletilla striata cultivation

[0004] And, in existing a large amount of patent documents and scientific and technological literature, for the weeding method in the bletilla striata planting process, all adopts the weeding treatment of weeding immediately, and assists the weeding of herbicide, makes the labor intensity in the weeding process bigger, and the cost higher, and will also affect the quality of Bletilla striata, making the planting efficiency of Bletilla striata lower and the profit lower; in view of this, some researchers have begun to study the new physical weeding technology of Bletilla striata, that is, in November every year, use dry pine needles or straw to Cover the whole surface. When the bletilla striata emerges, remove the dry pine needles or straw to expose the bletilla striata seedlings. The other free places are still covered to prevent weeds from growing. Pine needles have the effect of moisturizing and heat preservation, hindering the photosynthesis of weeds, making it difficult for most weeds to grow. Combined with the limitation of the amount of dry pine needles or straw covered, avoid too much coverage that will affect the growth of Bletilla striata, and avoid too little to reach the hindrance purpose of weed growth

Its operation is convenient and simple, but its weeding rate in the process of planting Bletilla striata is still low, and still requires a lot of labor to pull out the remaining weeds, and the pine needles and straw covered are difficult to be utilized, resulting in pine needles on the base. The difficulty of weeds and weeds is relatively large, especially the workload of removing the seedlings of Bletilla striata is relatively large, resulting in relatively high processing intensity and high cost
