Problems solved by technology

However, due to changes in site conditions, differences in the germination of the lateral buds of the underground stems of bitter bamboo have occurred, which has affected the development direction of bamboo components, resulting in plastic changes in the shape and physiological growth of bamboo, resulting in the growth of bitter bamboo shoots, which cannot meet the expected market demand and economic growth. benefit

Embodiment 1

[0025] Embodiment 1: Dachao Mountain bitter bamboo shoot base area of ​​Hengshan Town, Guangning County, Guangdong Province is 50 mu. The bitter bamboo forest was planted by the bitter bamboo that the bamboo farmers dug in Dachao Mountain before more than 10 years. state. In 2018, the average diameter of the bamboo in the bitter bamboo forest of the bamboo forest base was 1.25cm, and the average height was 2.25cm. Bamboos of different ages in the bamboo forest grow together alternately to form a mixed, and the bamboos are evenly distributed among each other, and the survival competition between adjacent bamboos is balanced; in terms of fertilizer management, foliar fertilizer is applied: 1 kg of liquid nitrogen fertilizer per mu, and 30 kg of water; Spray once at the end of June 2018 and once at the end of March 2019. When harvesting bamboo shoots in April 2019, keep the heads of the bamboo shoots to promote the germination of the side buds on the heads of the bamboo shoots. ...

Embodiment 2

[0026] Embodiment 2: Dachao Mountain bitter bamboo shoot base area of ​​Hengshan Town, Guangning County, Guangdong Province is 50 mu. The bitter bamboo forest is planted by the bitter bamboo that the bamboo farmers dug in Dachao Mountain more than 10 years ago. In the bitter bamboo forest, the bamboo crowns of bamboos are connected and closed. state. In 2018, the average diameter of the bamboo in the bitter bamboo forest of the bamboo forest base was 1.3cm, and the average height was 2.4cm. During the bamboo shoot period from April to April, 520 new bamboos were kept, and 85 bamboo shoots (referring to unearthed or unearthed shoots that could not grow into bamboos) were withdrawn, and then bamboos of different ages in the bitter bamboo forest were grown alternately to form a mixed The mixing degree is 0.75, and the mixing degree is expressed as In the formula: i is the central bamboo plant, j is the adjacent bamboo plant, if the central bamboo plant and the adjacent bamboo p...

Abstract

The invention discloses a small-diameter cultivation method for pleioblastus amarus for bamboo shoots. The method comprises the following steps of a, controlling the average diameter at breast heightof bamboos in a pleioblastus amarus forest to be 1.0-1.5 cm and the height to be 2.0-2.5 m; b, controlling the number of the bamboos in each mu of the pleioblastus amarus forest to be 400-500 in the first year, 400-500 in the second year and 400-500 in the third year; c, growing the bamboos of different ages in the pleioblastus amarus forest together in a staggered manner to form intercropping, making the positions of the bamboos uniformly distributed and balancing struggle for existence among the adjacent bamboos; d, spraying a foliar fertilizer once in mid-to-late June to promote the germination and development of bamboo rhizomes, and spraying the foliar fertilizer once at an early stage of shoot growth from late March to early April of the next year to promote the germination of side buds of underground stems and the shoot growth; and e, reserving basal parts of the bamboo shoots while harvesting the bamboo shoots, and promoting the side buds inserted into the basal parts of the bamboo shoots to germinate secondary water bamboo shoots or new bamboo rhizomes. According to the small-diameter cultivation method, a small-diameter growth pattern for bamboo species in the pleioblastusamarus forest is kept, the high-quality and high-yield targets of the small-diameter pleioblastus amarus are achieved, the market requirements are met and higher economic benefits are obtained.

Description

[0001] The invention relates to a small-diameter cultivation method of mixed bamboo species for high-quality bamboo shoots, in particular to a small-diameter cultivation method of bitter bamboo for bamboo shoots. Background technique [0002] Bamboo plants can be divided into three types according to the structure of rhizomes: synaxial cluster type, compound axis mixed type and uniaxial scattered type. The mixed-axis type bamboo has strong adaptability and phenotypic plasticity to the external environment. As a plant that mainly reproduces asexually, the basal lateral buds of the mixed bamboo plants can develop into new bamboo plants and new bamboo whips, and the underground bamboo whip lateral buds It can also develop into new bamboo plants and new bamboo whips; when the site conditions are good, the ground bamboo plants are scattered; when the site conditions are poor, the ground bamboo plants are distributed in clusters. These basic characteristics, which are obviously diff...
