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...

Embodiment 1

[0017] 1. Material preparation: water pipes; plastic film, 2 meters wide, about 10 kilograms per mu; bamboo bow, 2.2 meters long, 2 centimeters wide, about 300 kilograms per mu; shade, using crop straw curtains; thermometer.

[0018] 2. Nursery site arrangement: The nursery site should be selected in farmland or dry land with convenient transportation, flat terrain, sufficient water source and convenient drainage. The soil requires loose, slightly acidic sandy or light clay loam. It is not suitable to be used as a nursery for tobacco, hemp, and vegetable gardens. Thoroughly plow the seedling field for more than 80cm and fertilize, and make a fine furrow with a furrow width of 150 cm, a furrow width of 35 cm, and a furrow height of 20 cm. Drainage ditches are opened around the seedling field. The nursery generally uses 150 kg of decomposed cake fertilizer per mu, and 20 kg of superphosphate. Mix the fertilizer with the border soil for 3-5 cm, and then spread about 5 cm thick ...
