Persimmon fertilization technology Persimmon has deep roots and is fond of light but not tolerant of shade. Therefore, persimmon trees should be planted on the flat ground with thick soil layer, and there should be sunny graves on hilly terrain and hillside. If the groundwater is too high or the soil layer is barren and the root system is shallow, it is easy to cause plant aging and pest breeding. Transplanting fertilization is an important technique for persimmon fertilization. Deep roots, underdeveloped main roots and few fine roots. Therefore, when transplanting, burying is better than ordinary fruit trees, and 60 ~ 80 cm is appropriate.

Apply 20 ~ 30kg of compost and 0.5 ~ 1kg of phosphate fertilizer to each disaster, then fill the buried subsoil, then bury it in the tree mu, fill the medium-high soil in batches and stabilize it, and then cover the subsoil on the surface. In that way, the migration of mature soil to the lowest layer is beneficial to the growth and development of rhizomes, and the surface layer is covered with subsoil, which is beneficial to fertilization and cultivation.

The base fertilizer of persimmon fertilization technology should be turned over in the middle and late of 10 after dead leaves in winter, and the fertilization method is furrow application. The base fertilizer is mainly farmyard manure. Phosphorus, potassium fertilizer and potassium fertilizer are best mixed with farmyard manure. According to the tree size and conclusion, 25 ~ 50kg farmyard manure should be applied to each tree, and1~ 2kg phosphate fertilizer and 0.2 ~ 0.5kg ammonium sulfate should be infiltrated into the fertilization ditch to be symmetrical with the soil mixing platform, and then the soil should be filled.

Key points of topdressing fertilization technology for persimmon trees Forced fertilization can be applied with pure organic fertilizers such as urea and compound fertilizer. According to the crown diameter and conclusion, each persimmon tree is forced to apply 0.2 ~ 0.5 kg urea or 0.5 ~ 1 kg ammonium sulfate or rewarming fertilizer. In the stage of forced fertilization, mature seeds were topdressing 1 time in early July. Late-maturing seeds should be topdressing 1 time from June to July. Top dressing 1 time in September. It should be noted that the base fertilizer should not be too much and the time should not be too late. Otherwise, it is concluded that the alma mater is not rich enough, which will endanger the fruits of the coming year. At the beginning, the fruit showed color difference, delayed ripening and decreased quality.

Advantages of persimmon trees needing fertilizer Persimmons are produced in China, and there are natural persimmon trees on both sides of the Yangtze River. There are many kinds of persimmon trees, but they all have one thing in common, that is, the roots are very strong and developed, which can extend to 3 meters underground and have few fine roots. But there are many Keith Downing in the root, so the root can't get well after being injured.

Therefore, attention should be paid to the concentration and dosage when fertilizing to prevent root damage. Persimmon has strong vitality and can grow and develop normally in both acidic and alkaline soil layers. According to the experimental investigation, it takes 8-9 kilograms of nitrogen, 6-7 kilograms of potassium and 2-3 kilograms of phosphorus to produce a ton of persimmon. So persimmon trees have a great demand for nitrogen.
