Pinus tabulaeformis What should be paid attention to when fertilizing?

In warm and rainy areas, organic matter decomposes quickly, and organic soil nutrients are easy to leach. Pingdingsong base take The application of semi decomposed organic fertilizer and topdressing should be small and multiple times. Maturity of organic fertilizer can be caused by slow decomposition of organic matter in cold climates, but can not be caused by excessive use of organic matter. Therefore, the time of topdressing should not be too much, and the amount of each time can be increased appropriately.

 Pinus tabulaeformis

Pinus tabulaeformis The base fertilizer should be mainly organic fertilizer and mixed with mineral phosphate fertilizer. Nitrate and urea can not be used as base fertilizer. Nitrogen should not be used as base fertilizer in areas with heavy rainfall and easy leaching of fertilizer. Potassium fertilizer can also be combined with other fertilizer base fertilizers. Top dressing should be based on inorganic fertilizer, such as nitrogen fertilizer and potassium fertilizer. Generally, phosphate fertilizer is not used as topdressing.

Secondly, we must understand the effect of mixed management of nitrogen, phosphorus and potassium on Pinus tabulaeformis. Nitrogen, phosphorus and potassium are the three indispensable nutrients for the growth of Pinus tabulaeformis. If the nutrition is insufficient, the quality and yield of seedlings will be seriously reduced.
