Embodiment 1

[0021] 10 parts by weight of stacked retting sawdust through 9-month stacking, 1 weight part of stacked retting sawdust through 26-day stacking, 6 parts by weight of carbonized sawdust, and 2 parts by weight of tannin residue in a rubber bowl pulverized by a pulverizer Parts were added to a mixer and stirred evenly to obtain a soilless culture substrate. On February 25th, the Quercus macrophylla seedlings were transplanted into containers equipped with soilless culture substrates, and 0.5% compound fertilizer water solution was applied every 14 days. On May 25th, 10 parts by weight of yellow heart soil were used to add 1.5 parts by weight of fire soil. A mixed matrix was used as a control, and the test results are shown in Table 1.

Abstract

The invention provides soilless culture matrix for a castanopsis fissa container seedling, and a preparation method for the soilless culture matrix. The soilless culture matrix is characterized by comprising the following components in part by weight: 10 to 15 parts of stacked sawdust of which water content is 40 percent, 0.5 to 1 part of stacked tung bran, 2 to 6 parts of carbonized sawdust, 2 to 4 parts of tanning extract residue, or / and 2 to 4 parts of inorganic matrix, namely one or more of pearlite, vermiculite, and rock wool powder. The preparation method comprises the following steps of: adding the stacked sawdust, the stacked tung bran, the carbonized sawdust, the tanning extract residues or / and the inorganic matrix into a mixing machine respectively, and stirring or manually mixing uniformly to obtain the soilless culture matrix. In the soilless culture matrix, sawdust and tanning extract resources are fully utilized, and the matrix has better physical behavior, is more suitable for growth and development of plant root systems, and has the effects of controlling insects and diseases; the weight of the matrix is half all mud matrix; and transportation cost and forest planting cost are reduced, and the soilless culture matrix has good market application prospect.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation substrate preparation, and in particular relates to a soilless cultivation substrate of oak oak container seedlings and a preparation method. Background technique [0002] Castanopsis fissa, also known as Castanopsis fissa, also known as Castanopsis fissa, is an evergreen tree belonging to the Fagaceae castanopsis genus, and is mainly distributed in southeastern Asia, at latitude 26 north on the junction of the south-central subtropics. south area. my country is mainly distributed in Guangdong, Guangxi, Hainan, Fujian, Jiangxi and other places. In Guangxi, it is mainly distributed in the mountains and hills on both sides of the Xunjiang River Basin. Its bud regeneration ability is strong, and the secondary forest grows rapidly. 4m, 3 years can be used as forest and timber, can be used as fiber board, PVC composite material and excellent papermaking raw material. The leaves are thin and ...
