Tea planting techniques: how to fertilize tea trees in summer?

How to fertilize tea trees in summer? Please introduce how to apply summer fertilizer to tea trees for reference: after spring tea picking, a large amount of nutrients are consumed, new shoots stop growing, and root growth is strengthened, so it is necessary to apply fertilizer in time to replenish tree nutrients. According to the experiment, if 100 kg of dry tea is harvested from the tea garden, 10 kg of pure nitrogen should be compensated in order to maintain the original level of soil fertility. If it is expected to produce 150 kg dry tea per mu, 15 kg of pure nitrogen should be applied, of which 5 kg should be used as base fertilizer and 10 kg as topdressing. Organic manure, such as vegetable cake, compost, stable manure, green manure, etc., or as base fertilizer every year or every other year, can be used as interrow application, combined with phosphorus and potash fertilizer. In the fertilization of tea garden, the times of topdressing can be more appropriate, so that the seasonal distribution of available nitrogen in the soil is more balanced, and more nutrients can be absorbed at each peak of growth, so as to increase the annual yield. It is applied twice a year: 60% before spring tea and 40% before summer tea. Three times a year: spring tea, summer tea, autumn tea, 40%, 30%, 30%, or 50%, 25%, 25%, respectively. The ratio of nitrogen, phosphorus and potassium is 2: 4, 1: 1, 1: 1. Generally per mu of tea garden, 15 kg of urea, 11.5 kg of calcium or calcium magnesium phosphate fertilizer and 7.5 kg of potassium chloride are applied in the summer fertilizer, combined with loose soil in the tea garden to weed, dig a small ditch 12-15 cm deep at the outer edge of the tea crown drip line, and cover the soil immediately after deep application, and it is best to apply summer tea fertilizer in early June.
