Pipe insertion ventilation method suitable for covering phyllostachys praecox forest in southern China

Abstract

The invention relates to a pipe insertion ventilation method suitable for covering a phyllostachys praecox forest in southern China. The method comprises the following steps: in a selected phyllostachys praecox planting area, determining a pipe insertion position and carrying out pipe insertion treatment; after pipe insertion is finished, uniformly covering the earth surface of the phyllostachys praecox forest with chicken manure, bamboo leaves and straw covering materials, and increasing the temperature through organic matter fermentation; evenly covering the organic covering material with rice husks and rice chaff to serve as a covering heat preservation layer; after covering of the heat preservation layer is completed, straightening and reinforcing the inclined pipe in the covering process; uniformly scattering a ventilation thermal insulation material into a pipe; and after covering is finished, removing the covering material, pulling out the pipe, and mixing perlite into the soil. According to the method, the pipe is inserted in the covering phyllostachys praecox forest, the good ventilation and heat preservation effects can be achieved, growth of the overground part and the underground part of phyllostachys praecox can be promoted, the yield of phyllostachys praecox shoots can be increased, bamboo rhizome floating caused by long-term covering of phyllostachys praecox can be relieved, degradation and land retirement of the phyllostachys praecox forest can be effectively avoided, and then the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to an intubation ventilation method suitable for covering thunder bamboo forests in southern my country. Background technique [0002] Phyllostachys praecox is an excellent bamboo species for scattered bamboo shoots in my country. Its main production areas are Lin'an, Anji, Deqing and other counties in Zhejiang Province. One bamboo shoot", and was widely introduced in Anhui, Jiangxi, Hubei, Fujian, Jiangsu, Sichuan and other places, and the cultivation area continued to expand. Biomaterial mulching, as a high-efficiency cultivation technology for early bamboo shoots, is widely used in the management of Phyllostachys praecox, which makes Phyllostachys praecox high in cultivation economic value, and the annual income per mu can reach 30,000 yuan, which is the best way for the majority of bamboo farmers to increase their economic income. important means. Howe...

Problems solved by technology

At present, the commonly used means of increasing oxygen for soil hypoxia generally include deep plowing and oxygen irrigation, etc., but they are not suitable for mulched bamboo forests. The technique of intubation and ventilation in bamboo forest is particularly necessary
