ТЕХНОЛОГИИ ЗАКЛАДКИ И УХОДА ЗА ЧАЙНЫМИ ПЛАНТАЦИЯМИ

Abstract

The use of fertilizers is one of the most eff ective methods for ensuring a steady increase in the yield of tea plantations and maintaining it at a high level. The author analyzed agrotechnical requirements for the establishment and maintenance of tea plantations, taking into account the specifi c natural production and physiological characteristics of tea plants. The paper considers the infl uence of agrotechnical methods for the care of tea plantations on their productivity, such as: fertilizing, pruning, and cultivating the soil in the inter-rows. It has been established that both mineral and organic fertilizers greatly infl uencence on the development and productivity of tea plants. The latter type in the form of manure or peat compost, when applied in 4 years one time at a rate of 50 t/ha, gives an excellent eff ect. First, organic fertilizers are used for plantations located on slopes or fl at areas with heavy soils. Doses of nitrogen fertilizers are set depending on the age and yield of the tea plantation. It is noted that plantations with closed rows and trellis trimming do not need deep tillage. On such plantations, it is recommended to carry out winter tillage every 3-4 years with the simultaneous intra-soil application of phosphorus and organic fertilizers. The timing of applying phosphorus fertilizers can be adjusted depending on their content in the soil. It is recommended to leave the trellis pruning material on the plantations as an organic fertilizer for plant nutrition. According to the current agrotechnical requirements, the optimal indicator of soil acidity, at which a tea plant shows maximum viability and can give the highest leaf yield, is PH = 4.0…6.5.
