How to fertilize tea in autumn? Please guide the tea garden now is a good time to fertilize, based on your own experience to briefly introduce the tea garden autumn fertilization problem. In production, many farmers are used to fertilizing tea in spring, do not pay much attention to fertilization in autumn, and like to apply urea, ignoring phosphorus and potassium fertilizer and medium trace element fertilizer, resulting in poor tea quality, low yield and economic benefit deviation. Like other perennials, the growth of tea is divided into two parts: aboveground and underground. In autumn, when the new shoots of tea stop growing, the underground roots will continue to grow for a period of time, during which enough nutrients will be accumulated and stored in the roots and stems for the growth of new buds and shoots after the beginning of spring next year. After the beginning of the next spring, due to the low soil temperature, the root growth is not prosperous, and the germination of new buds needs a lot of nutrients, which is mainly supplied by the accumulation of nutrients in the previous year. At this time, if there is not much nutrient storage in the rhizome, it will soon be consumed, and the emergence of new buds and shoots will soon stop. As a result, the quality of bud heads is very poor, there are more "spreading leaves", and the weight is relatively insufficient. Seriously affect the economic benefits of tea garden, not to mention it is easy to lead to premature senescence of tea trees. Therefore, the heavy application of autumn fertilizer is very important to the yield of tea garden. The fertilization time in autumn is suitable from the end of September to the middle of October, and the climate is different in different places. Types of fertilization: high nitrogen, low phosphorus, low potassium (or medium potassium) compound fertilizer is better, magnesium, zinc, boron fertilizer can be properly supplemented, pay attention to calcium fertilizer should not be too much, otherwise the leaf quality will become worse! The quantity of compound fertilizer is 40-60Kg/ mu, and the fertilizer of medium and trace elements depends on the variety and brand. Fertilization is best combined with soil or mulch, some tea gardens do not prepare the soil, can be combined with autumn cutting application, first fertilization and then pruning, the use of fallen leaves and other mulch. After the beginning of spring, urea 8-10Kg/ per mu was used as budding fertilizer ten days before the germination of new buds, and then urea could be supplemented appropriately according to the picking situation, usually 2-3 times, until the end of spring tea picking. Relatively speaking, the cost of this method does not increase much, the effect of increasing production is remarkable, the quality of tea is good, and the benefit is better by many growers in our area.
