A kind of dish-shaped training bag film-covering method for young Camellia oleifera forest

Abstract

The invention discloses a plate-shaped cultivating bag film mulching method for a tea-oil tree young stand. The method comprises the following steps of (1) time selection, (2) agricultural film preparation, (3) weeding and bag cultivation, and (4) agricultural film mulching. The time selection is carried out two months after planting of tea-oil trees. According to the agricultural film preparation step, a polyethylene film is cut into square pieces with the length and the width both of 1.1m, and cross-shaped cuts with the transverse and longitudinal lengths both of 15cm are cut in the middle for standby application. According to the weeding and bag cultivation step, weeds around the tea-oil tree saplings are removed, surface soil is harrowed and smashed into fine soil and is held together to form soil mounds which are similar to a plate shape, and an annular groove is hoed along the periphery of each soil mound. According to the agricultural film covering step, the agricultural film with the cross-shaped cuts cover the plate-shaped soil mounds by crossing the tea-oil tree saplings, 4 to 6 air holes with the diameter of 1cm are stabbed in the agricultural film, a small amount of loosened soil covers the peripheries of the air holes of the film, and the periphery of the film is compacted through soil blocks. The plate-shaped cultivating bag film mulching method for the tea-oil tree young stand has the advantages that evaporation of soil moisture can be reduced during high temperature and drought periods, ground temperature on the peripheries of the tea-oil tree saplings can be improved during winter severe cold time, the effects of activating soil, preserving heat, and reducing fertilizer competition of weeds are performed, and the survival rate of the tea-oil tree saplings is improved.

Description

technical field [0001] The invention belongs to the technical field of plant planting, and in particular relates to a method for covering a plate-type cultivation bag for young Camellia oleifera forests. Background technique [0002] Film mulching cultivation is to increase the crop yield by covering the land where crops are planted with plastic film to increase soil temperature, maintain soil moisture and nutrients, and create a soil ecological environment suitable for crop growth. It is the key to high-yield cultivation of crops in the 20th century One of the technologies, especially in the agricultural production in the arid areas of northern my country has been widely used. In recent years, with the dream-seeking development of the camellia oleifera industry, the planting area of ​​camellia oleifera has grown rapidly, but the low survival rate of new afforestation of camellia oleifera has always been a common problem in production. According to survey statistics: the surv...

Problems solved by technology

However, this technical solution is suitable for afforestation tree species in arid areas in the north, and is not suitable for the planting of the dominant economic forest tree species in the south - Camellia oleifera, and the cost of the program is relatively high
