Cancer of tea root
Symptoms occurred in Anhui, Zhejiang, Guangdong and other provinces. It mainly harms the roots. At the beginning of the disease, the main root and lateral root produced light brown spherical protuberances, and then expanded into tumors, small ones like grains, large ones like broad beans, multiple small tumors gathered together to form large tumors, and later tumors became brown and Lignification, rough surface and hard texture. Cutting seedlings infected with little or no roots, resulting in slim plant weakness or leaf yellowing and shedding, plant death. Pathogen Agropyi μ Mt μ mefaciens

Radiation breeding of tea plant
The variation of tea tree was induced by radiation, which was selected and bred into a new variety. Compared with traditional breeding methods, radiation breeding can generally increase the mutation frequency by about 1000 times, which is more effective for changing one or two characters. it has the characteristics of breaking the old linkage and transplanting chromosome fragments, overcoming distant cross incompatibility, using self-incompatibility of cross-pollinated plants to self-compatibility, and producing mutation types that rarely exist in nature. Radiation has ionizing radiation and heat.

Anti-freezing remedy and Restoration measures of Tea Plant
Since January 11, the rainy and snowy weather in Hubei province has lasted for more than half a month and has evolved into a "snow disaster". The seriousness of this disaster lies in the overlap and long duration of low temperature and rain and snow, which has a great impact on agriculture in Hubei Province, and tea is no exception. From the investigation and understanding of various tea areas, most tea gardens in our province have varying degrees of frost injury, which will be more serious if effective measures are not taken, and the impact on the production of spring tea in the province this year is almost a foregone conclusion, and the opening of spring tea garden is at least 10-15 days later than in previous years. In this paper, the anti-freezing and remedial measures of tea trees are mentioned.

Seedling raising technique of short-spike cuttage of tea plant
First, the selection of mother trees and the cultivation of cuttings: the vigorous growth, the same characters of improved varieties, and the disease-free garden were selected as the mother garden, and then the mother trees were selected in the mother garden, and the selected mother trees did not pick tea, but left shoots to cultivate cuttings, generally leaving spring shoots as summer cuttings, summer and autumn shoots as autumn and winter cuttings, and topping about 13 days before cutting. Second, nursery land selection and management: select areas close to the new planting garden, convenient transportation, loose and fertile soil slightly acidic red-yellow loam, convenient drainage and irrigation. Ploughing and tanning, raking and smashing, removing grass roots, tree roots, sundries, etc. According to the width of the border 1 meter

Measures to prevent tea trees from blooming
In summer and autumn every year, tea trees not only have tea buds and flower buds in the same year, but also have fruits developed and matured last year, forming the phenomenon of "carrying a baby", which affects the yield and quality of Ding Xianye. In order to improve the yield and quality of tea, the measures to prevent tea from blooming are introduced as follows: 1. Spray gibberellin. During the peak period of physiological differentiation of flower buds, gibberellin 100 mg / kg per mu plus 2% urea aqueous solution 75% 100 kg was sprayed evenly on the front of the leaves. Gibberellin can stimulate the elongation and division of primordial cells in tea buds.

Ways to deal with the flowering of tea trees
Yu Huaijiong, Guihua Village, Yuping Town, Hongya County, wrote that: at present, a large number of local tea trees blossom and bear fruit, consuming tea nutrients and affecting tea production in the coming year. Ask what pollution-free pesticides can be used to remove flowers and fruits from tea trees to ensure a bumper tea harvest in the coming year. Liao Changli, an expert on tea cultivation in Pujiang County, replied: the climate was hot and dry in the early stage of this year, and Rain Water increased in the later period, resulting in stagnant water in some low-lying areas with poor drainage, and the recent warm winter, and three factors led to the blossom and fruit of tea trees in some parts of our province.

Cultivation and management of tea trees in greenhouse
Covering plastic greenhouse in tea garden is an important cultivation and management technology to advance the mining time of famous and high-quality tea, improve quality and greatly increase economic benefits. The main function of the greenhouse is heat preservation and frost prevention, generally from late October to late December of the first year, the cover film is built before the frost comes, and the film can be uncovered in the first and middle of April of the following year. The suitable temperature for tea growth in the greenhouse is 20 ℃ ~ 25 ℃, the highest temperature can not exceed 30 ℃, and the lowest temperature can not be lower than 8 ℃. The temperature in the shed may exceed 30 ℃ at noon on a sunny day, so you must open the door.
