Method for planting Bletilla striata seedling under broad leaved forest

Abstract

The invention discloses a method for planting Bletilla striata seedlings under a broad leaved forest. The method mainly comprises Bletilla striata sterile seedling cultivation, greenhouse domestication, and planting under a broad leaved forest. The method comprises: after a Bletilla striata seedling planting field under a broad leaved forest is applied by a water-logged compost as a base fertilizer, making a bed, covering a black plastic mulching film on a bed surface; digging a pond on the bed surface which is covered by the black plastic mulching film, to plant Bletilla striata seedlings, in the planting pond, covering fine earth and then covering manure coffee shells, digging a pond on the bed surface which is covered by the black plastic mulching film, to plant Bletilla striata seedlings, soil humidity maintaining in 70-80%, respectively performing topdressing once in spring and autumn each year, topdressing being 30-40 kg / mu of superphosphate and 100 k / mu of a water-logged compost. The method can effectively inhibit growth of more than 70% weed in the Bletilla striata seedling planting field under a forest, effectively improves soil fertility, and soil organic matter content is improved by 68%-88%, the number of topdressing is reduced, and Bletilla striata tuber fresh yield is improved by 15-18% in each mu.

Description

technical field [0001] The invention belongs to the technical field of plant seedling cultivation, and in particular relates to a method for planting white and broad-leaved seedlings under a broad-leaved forest. Background technique [0002] Bletilla striata (Bletilla striata) is a plant of the genus Bletilla striata, the dry tuber (pseudobulb) of Bletilla striata, also known as Bletilla striata, Bletilla striata, ground screw, white chicken baby, purple orchid, etc. It is mainly produced in Guizhou, Yunnan, Sichuan, Chongqing, Shaanxi, Zhejiang and other provinces and cities. It is planted on a certain scale in Zheng'an, Guizhou, Xunyang, Shaanxi, Nanchuan, Chongqing, and Xuancheng, Anhui. Baiji is a commonly used variety of Chinese medicinal materials. It is traditionally used for lung and stomach bleeding, traumatic bleeding, bloated sores, chapped skin, water and fire burns and other diseases (injuries). Ulcerative colitis and other diseases. With the development of mo...

Problems solved by technology

[0003] The seeds of Baiji are small and large in number, but due to the lack of endosperm, the seeds cannot be used for large-scale cultivation of seedlings by conventional methods. In production, seedlings are generally obtained by division propagation, but due to the low reproduction coefficient, the number of seedlings produced is extremely limited and cannot Adapt to the needs of industrial production

Moreover, when planting under the broad-leaved forest, there are problems that the growth of weeds is greater than the growth of the seedlings of the broad-leaved forest, the moisture retention of the seedlings planted under the forest, and the improvement of the soil fertility of the forest land, which seriously restricts the industrialization of the planting of the broad-leaved plant.

[0004] At present, the technology of aseptic sowing and raising seedlings of Baiji seeds is adopted, but the large-scale cultivation of Baiji broad-leaved forest is still in the preliminary stage. During the conventional cultivation of Baiji, the growth of weeds is often greater than that of Baiji seedlings, and the seedlings are short of water and lack of water. fat problem
