Abstract

The invention discloses a cultivation method of sympodial bamboos used for producing high-cellulose-content fibers. The cultivation method of the sympodial bamboos used for producing the high-cellulose-content fibers comprises the following steps: preparing a compound solution used for adjusting and controlling a cellulose content of the sympodial bamboos, wherein the compound solution comprises the following components: polypeptide urea with a concentration of 5-20 mg / L, a gibberellic acid (GA3) with a concentration of 5-15 mg / L, 2-diethylaminoethyl hexanoate with a concentration of 15-25 mL / L, potassium dihydrogen phosphate with a concentration of 80-120 mg / L, Zn(NO3)2.EDTA with a concentration of 8-12 mg / L, sodium molybdate with a concentration of 0.1-0.2 mg / L and MgSO4.7H2O with a concentration of 30-60 mg / L, and a pH value of the compound solution is 6-6.5; adjusting the basic soil fertility through fertilization; and planting 40 sympodial bamboos per mu according to spacing in rows and spacing between the rows of 4*4 m, and keeping 10-15 annual or biennial bamboos of each sympodial bamboo. According to the cultivation method of the sympodial bamboos used for producing the high-cellulose-content fibers, cultivation of a sympodial bamboo raw material used for high-quality fibers is regarded as the purpose, operation is simple, the bamboos grow fast, the bamboo cellulose content is high, the cellulose content of the biennial bamboos is, on average, 14.1% higher than that of untreated controls, and directional cultivation of a bamboo forest used for the high-quality fibers can be achieved.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for cultivating clustered bamboo for producing fiber with high cellulose content. Background technique [0002] The pulp and paper industry is one of the important pillar industries of today's economy. With the rapid development of social economy, the demand for paper will increase rapidly. Due to the current shortage of forest resources and the continuous improvement of laws and policies related to forest protection series, as well as the relatively low recycling rate of waste paper in the paper industry chain. However, as a widely distributed plant natural resource, bamboo has the characteristics of wide distribution, strong adaptability, fast growth, early maturity, and high economic value. It lasts for decades to hundreds of years. The cellulose content of bamboo is between 40% and 60%. Its excellent pulping performance can be compared with some wood fibe...
