Soilless Cutting Substrate and Cutting Method of Nanchuan Big Tree Tea

Abstract

The invention relates to the technical field of soilless cultivation, in particular to a soilless cutting matrix and a cutting method for Nanchuan camellia arborescens. The soilless cutting matrix includes the following raw materials: peat, earthworm manure, vermiculite, perlite, humic soil, vinegar residue, diammonium phosphate and fermented rice husk. The cutting method for Nanchuan camellia arborescens includes the following steps: S1, taking cuttings from semi-lignified branches of Nanchuan camellia arborescens, cutting the cuttings and retaining a complete leaf and a strong axillary bud on each cutting, and soaking the cuttings in rooting solution for 2-4h before use; S2, preparing a matrix according to a proportion, putting the matrix in a seedling raising tray, inactivating the matrix bacteria with carbendazim diluted at a factor of 1000-1200, and adjusting the pH; S3, washing the cuttings with clean water, and cutting the cuttings into the matrix-containing seedling raising tray for seedling raising; and S4, putting the seedling raising tray with the cuttings in a greenhouse. Camellia arborescens cultured by the method has high survival rate.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a soilless cutting substrate of Nanchuan big tree tea and a cutting method thereof. Background technique [0002] Nanchuan big tree tea is a kind of wild big tea tree, mostly small trees or trees, the tree age ranges from several decades to hundreds of thousands of years, the young leaves are hairless or less hairy, and the leaf margins have sparse blunt teeth or no serrations at all. The leathery leaves are thick and hard to twist into strands. The color of mao tea is mostly dark green, the main and auxiliary leaf veins are strong and obvious, the green tea is mostly dark green, the tea is smooth and heavy, the aroma is deep and specific, and the taste is very low. , but the water is sweet and the sweetness is long and stable. The foam resistance is more than 2 to 3 times higher than that of ordinary tea. It is the best tea. [0003] Nanchuan big tree tea has the f...
