Intelligent rapid propagation method of tea tree

Abstract

The invention discloses an intelligent rapid propagation method of tea tree. The method comprises the following steps: (1) growing environment: setting parameters of temperature, humidity and nutritional environment required for rapid growth of tea seedlings by using an intelligent control system; (2) seedling culture matrix: sufficiently and uniformly mixing sugar-free perlite and sandy yellow soil with soil pH value between 4.5 and 5.5 in a weight ratio of 1:(3-5); (3) seedling bed sterilization and disinfection treatment: spraying the seedling bed with 800-1,000 time mildothane or carbendazim solution before cuttage; (4) cuttage: ensuring that the cut is smooth and the upper cut is 0.2-0.3cm from the blastema; (5) seedling phase management: carrying out conventional short-ear cuttage management. The method has the advantages of short seeding period and high efficiency; moreover annual production can be performed, and breeding materials can be saved; and the original excellent properties of the tea tree can be maintained, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a seedling raising method. [0002] Background technique [0003] At present, the method of raising seedlings of improved clones of tea trees is developed at home and abroad. The main method is steel-framed plastic greenhouses plus warming to achieve rapid factory reproduction. Using soil as a cultivation substrate under high humidity conditions has slow water permeability and poor permeability, and it is difficult to raise seedlings. Generally, it takes 12 to 16 months, the cycle is relatively long, and the management cost is high. The survival rate of tea seedlings planted in winter is low due to severe low temperature or long-term drought in winter and spring. [0004] Contents of the invention [0005] The object of the present invention is to overcome above-mentioned shortcoming and provide a kind of seedling raising period short, high efficiency, can year-...
