Single-node cutting seed-raising method of tea plant

Abstract

The invention relates to a method of cuttage propagation for short spikes of a tea plant, which can prevent cuttage seedling from being damaged by drought and frost in the winter, and increase the survival rate and the rate of outplanting. The method comprises trimming nursery lands, cutting the short spikes, watering, covering the lands with film and uncovering the film in the spring. As a preferable scheme, the method requires fully watering after cutting the short spikes, spraying with fine water fog, uniformly and deeply watering until rooting holes are close and the short spikes do not fall down. Regularly, trimming nursery lands is carried out during the period from the later September to the middle October The invention has the following advantages: (1) because the short spikes are fully watered at a time and covered with mulches and grass during cottage period, the temperature and the humidity are kept; it is unnecessary to water in the whole winter; procedures are reduced; and production cost is decreased, (2) the root systems of the tea seedlings are good; the tea seedlings grow fast; the survival rate of nursery stock can reach over 90%; and the rate of outplanting can reach 80%; (3) rooting the short spikes which is postponed to the period from the later September to the middle October is beneficial to adjusting farming season.

Description

technical field [0001] The invention relates to a method for raising seedlings by cuttings of tea trees, in particular to a method for raising seedlings by cutting short spikes of tea trees, and belongs to the technical field of agricultural cultivation. Background technique [0002] The tea tree short spike cutting seedling raising method saves material, improves the utilization rate of materials, and has a high survival rate and a large reproduction coefficient; the utilization rate of the nursery is high, and the number of seedlings per unit area is large; the cuttings are not restricted by the age of the tree and the variety of the tea tree. The main method of current tea tree breeding. At present, the method for growing seedlings of tea tree with short spike cuttings comprises the following steps: arranging nursery ground, cutting short spikes, setting up a shed after watering, and covering straw curtains or sunshade nets. However, cutting seedlings are prone to drough...

Problems solved by technology

However, cutting seedlings are vulnerable to drought and freezing in autumn and winter. Not only do they need frequent watering, but the survival rate and emergence rate are low, 60-70% and 50-60% respectively.
