Tea garden accurate fertilization five heavy four to see three

Accurate and rational fertilization is a necessary way to ensure the increase of yield and quality of tea gardens and to promote the growth of tea trees. There are two methods: root fertilization and foliar fertilization. Root fertilization has basic fertilizer and topdressing, and foliar fertilization is mainly used for topdressing.

According to the demand for nutrients in tea trees, tea tree fertilization should be based on the principle of five principles. Heavy organic fertilizer, fulfilling the linkage of organic fertilizer and inorganic fertilizer; heavy base fertilizer, fulfilling the connection between base fertilizer and topdressing; heavy spring fertilizer, fulfilling the connection of spring fertilizer and summer and autumn fertilizer; diazo fertilizer, fulfilling the connection of nitrogen fertilizer with phosphorus and potassium fertilizer; Fertilizer, fulfilling the link between root fertilizer and foliar fertilizer.

Tea tree fertilization still has to look four, "Look at the sky, look at the trees, see the soil, see the fat." Seeing the sky is based on the situation of meteorological changes. During the production of famous spring tea in early spring, the weather changed frequently. If the rain fell on the second day of urea application, the urea would be leached in large quantities. This had to be replenished, and the ammonium sulfate and ammonium bicarbonate were applied, and it did not rain immediately after application. Will be lost in large numbers, and the effect of fertilization will be better. Seeing soil is based on the characteristics of the soil to fertilize, the acid garden of the tea garden, it is best not to use acidic or physiological acid fertilizer. Neutral soil tea gardens are best used with acidic or physiological acid fertilizers. The tea garden with heavy sand content should be applied to lake mud, pond mud and pig manure. Tea gardens with heavy soil weight should be applied with grass ash, sheep feces, rabbit feces, etc. Looking at the tree is based on the variety and growth of the tree. Early buds should be chased early, and late buds should be chased later. Seeing fertilizer is based on the characteristics of the fertilizer to fertilize, ammonium bicarbonate is easy to burst, should be applied deep, while applying the side cover, can also be mixed with superphosphate, will reduce evaporation. Urea and compound fertilizers should be applied early and applied tightly. It is preferred not to apply a chlorine-containing fertilizer; that is, to apply it, it should also be applied in small amounts.

You should pay attention to the following three aspects when fertilizing. 1. Organic fertilizer must be fully decomposed. It is best to use a professional starter to solve. It not only reduces the loss of nutrients, but also completely eliminates harmful substances such as pathogens and eggs in organic fertilizers. 2. Application of microbial fertilizer. The biological bacterial fertilizer not only contains a large number of nitrogen-fixing, phosphorus-dissolving and potassium-dissolving active bacteria, but also contains organic matter, humic acid and trace elements, and can be applied in combination with other fertilizers in any fertilizer season. High-quality bacterial fertilizer can not only save the amount of fertilizer used, but also solve the problems of soil compaction and growth of soil microbial content. 3. Foliar sprayed seaweed fertilizer. The golden baby seaweed powder type microbial agent (0.5 kg/mu) was mixed with water, and the supernatant was taken for foliar application, and the residue was applied to the root. On cloudy or dusk, spray on the back of the leaves.
