Tea tree cutting seedling cultivation method

Abstract

The invention relates to a tea tree cutting seedling cultivation method. The tea tree cutting seeding cultivation method includes the following steps: paving fin sandy soil on a seedling bed as a cuttage soil, covering the cuttage soil with a degradable weeding film, and covering the degradable weeding film with fine yellow soil with the thickness of 0.4-0.6 cm; reserving branches which are cut off in a tea garden, spraying the branches with lime sulphur, putting the branches in a cool place for one week, and using the branches as scions for use; building an arc shed, covering the arc shed with a white plastic film, covering the white plastic film with one or two sunshade nets, and avoiding watering; removing the white plastic film to train seedlings while the height of the seedlings reaches 3 cm; reinformcing fertilizer and water management, applying self-prepared quick rooting fertilizer liquid once every 7-10 days, alternatively performing root fertilizing and leaf fertilizing for 6-7 times, removing the sunshade nets in the middle-last ten days of the September, watering the seedlings with the self-prepared quick rooting fertilizer liquid once again, and transplanting the seedlings in November-December in the same year when the seedlings are 25 cm in height and are semi-lignified. The method uses the pruned branches of spring tea trees to perform cuttage, will not affect spring tea production, can avoid watering, is low in cost, is high in survival rate, and is short in outplanting time.

Description

technical field [0001] The invention relates to a method for growing seedlings by cuttings of tea trees, and belongs to the technical field of plant cutting propagation. Background technique [0002] Tea contains catechin, cholesterolenone, caffeine, inositol, folic acid, pantothenic acid and other ingredients, which can improve human health. Tea drink-tea is known as "one of the three major beverages in the world". Therefore, tea tree planting has Very large economic value. Therefore, the cultivation technology of tea trees has also become the focus of everyone's research. [0003] At present, the traditional cutting methods are as follows: [0004] (1) Establish ear gardens: normal management takes 5 years to put into production. If you don’t build ear gardens, you can buy cuttings from other ear gardens; [0005] (2) Land selection: Paddy fields or gardens with good humidity, water diversion and drainage should be selected to facilitate watering; [0006] (3) Soil prep...

AI Technical Summary

Problems solved by technology

[0013] (1) To establish a special ear garden: it takes 5 years from establishment to production and use, which consumes a lot of manpower, material and financial resources. If there is no ear garden, you must buy cuttings from other ear gardens, which will cost a lot

[0014] (2) High cost and long time-consuming: the temperature is high in summer, the tea seedlings are vulnerable to sunburn, and the survival rate is low. On the other hand, the water requirement is high. Watering twice a day consumes a lot of manpower and material resources

It took 16 months from planting seedlings in the summer of the year to the autumn and winter of the second year, and the survival rate was low, only about 70%.

[0015] (3) A large amount of yellow heart soil is required for cuttings: traditional cuttings use a large amount of yellow heart soil (also called sterile soil) to inhibit the growth of weeds and prevent the occurrence of diseases. This yellow heart soil must be purchased in mountain farms with loess, which costs a lot of money and destroys Soil structure, causing soil erosion, damaging the environment

[0016] (4) Low survival rate and long time: the temperature and humidity of traditional short ear cuttings are unevenly controlled, high temperature will cause daily damage to tea seedlings, and low temperature will not be conducive to the growth of tea seedlings

[0017] The temperature in Jiangnan area is high in summer, but the temperature of the seedbed is low in the rainy season, and the cuttings are loosened by heavy rain, which is not good for the roots. Secondly, it rains for a long time, which makes the leaves polluted and prone to fungal diseases. Roots will also rain for a long time and cause root rot, which seriously affects the survival rate of tea seedlings

The survival rate of seedlings raised by traditional methods is only 70%
