Plum tree humic acid organic water soluble fertilizer plan

1. The timing of plum tree applying base fertilizer

The suitable period for applying the base fertilizer is autumn (1 month before the leaves), followed by the leaves until the freezing, and before the spring is thawed to the time of germination. The autumn-based fertilizer has sufficient time to be decomposed, and can make the roots heal and send new roots. Therefore, it is the peak growth period of the roots. The roots have strong absorption capacity, which can improve the storage nutrient level of the trees after absorption. Promote the development of flower buds, the higher nutrient storage of the tree and the timely supply of nutrients in the early spring soil, which can meet the needs of spring germination, flowering and fruiting and new shoot growth. After defoliation and spring application of base fertilizer, the effect of fertilizer effect is late, and the effect on the growth and development of fruit trees in early spring is very small. When the fertilizer is widely absorbed and utilized, it often reaches the prosperous period of new shoots. In the orchard with dry and no water pouring conditions in the mountainous area, the base fertilizer cannot be immediately watered after application of the base fertilizer, so the base fertilizer can also be applied in the rainy season. But organic fertilizer must be a fully decomposed sperm, the rate of fertilization should be fast, and pay attention not to damage the roots.

2. The correct method of applying plum fertilizer to plum tree

When the organic fertilizer source is insufficient, straw, weeds, etc. may be supplemented and mixed with organic fertilizer. It is worth noting that although the organic fertilizer source is limited, it must follow the principle of ensuring local and ensuring the centralized distribution of roots, and adopting concentrated acupoints to give full play to the fertilizer effect of organic fertilizer. Concentrated hole application is to dig a hole of 50 cm deep and 30-40 cm in diameter from the edge of the crown. The number depends on the amount of fertilizer. Then mix the organic fertilizer with the soil 1:3 or add some straw. Water in the hole. In addition, phosphorus, potassium fertilizer or even zinc, iron fertilizer, etc. can be mixed with organic fertilizer to improve its utilization. It is recommended that you use Fuyusu Humic Acid Water Soluble Fertilizer, which is converted from organic matter, which is rich in nutrients required by plants, and can improve soil compaction, acidification and other problems, including humic acid The main fulvic acid is greatly helpful for improving crop yield and quality, and can improve plant resistance and make plants grow healthier.
