The role of fertilizers is mainly to provide N, P, and other nutrients to trees. The correct fertilization method can make the trees better absorb nutrients and grow well. Therefore, it is very important to master the correct fertilization method.
1. Due to the wide distribution of root groups of trees, the absorption of nutrients and moisture are all in the fibrous roots. Therefore, fertilization should be around the roots and not near the trunk.
2. Trees with strong roots and deep distribution should be deep in fertilization, and the range should be large, such as oil pine, ginkgo biloba, skunk, acacia, etc.; trees with shallow roots should be lighter in fertilization, and the range should be small, such as Fatong and Amorpha fruticosa. And flower shrubs and so on.
3, organic fertilizer should be sufficient fermentation, maturity, should not use raw manure, and the concentration should be thin, chemical fertilizer must be completely crushed into a powder, should not be applied in blocks.
4, after fertilization (especially chasing fertilizer), must be timely and appropriate irrigation, so that the fertilizer infiltrated into the soil.
5, should be selected sunny weather, dry soil when fertilized. Rainy days, due to the slow absorption of water by the roots, not only the nutrients are not easily absorbed, but also the fertilizer can be washed away by the rain, causing waste.
6, sand, slopes, rocks are likely to cause loss of nutrients, fertilizer should be deeper.
7. Nitrogen fertilizer has strong mobility in the soil, so shallow application penetrates into the root distribution layer and is absorbed by the trees; Potassium fertilizer has poor mobility, and the mobility of phosphate fertilizer is even worse. It should be applied deep to the most distributed root system.
8, base fertilizer due to play a slower fertilizer effect should be deep, top dressing fertilizer effect is faster, it should be shallow Shi, for the timely absorption of trees.
9. Foliar spraying fertilizer enters the leaves through the stomata and stratum corneum, and then it is transported to various organs. Generally, the young leaves are older than the leaves, and the leaves do not absorb water faster than the leaves, and the absorption rate is also high. Therefore, the actual spray must be sprayed evenly on the back of the leaf, so that it is beneficial to the absorption of the trunk.
10. The foliar spraying fertilizer should strictly control the concentration so as not to burn the leaves. It is best to spray on cloudy days or before 10 o'clock in the morning and after 4 o'clock in the afternoon so as to avoid high temperatures and rapid solution concentration, affecting spray fertilizer or causing phytotoxicity.
