Fruit tree test soil fertilization precautions

Soil Testing Formulas Balanced fertilization is an important technique for fertilizing fruit trees. In the process of balanced fertilization of fruit trees in soil testing formulations, the following issues need to be noted:

1. Fruit trees absorb nutrients from relatively fixed soils. To make tree production stable, it is necessary to quantitatively supplement nutrients due to trees. Therefore, the type of supplemental nutrients and the amount of supplements should be based on the amount of nutrients present in the soil, the nutrients that are absent from the soil and needed by the tree, and the planned output. For over-existing trees, the amount of nitrogen fertilizer should be controlled; for the trees with weaker growth, the amount of nitrogen fertilizer should be increased; for orchards with low potassium, the proportion of potassium should be increased; for orchards with low rapidly available phosphorus, the number of orchards should be increased. Phosphate fertilizer application amount.

2. The proportion between nutrient elements has an impact on the growth of fruit trees. There are antagonistic effects between nutrient elements. If the amount of nutrient elements is more than enough and the proportion is imbalanced, the nutrient elements cannot be fully utilized, resulting in wasted nutrient elements or A deficiency of the disease occurs. Therefore, pay attention to the proportion of various nutrients when fertilizing.

3. Pay attention to the effect of soil environmental factors on the use of nutrient elements. Soil environmental factors include soil organic matter and pH. Organic matter can play a role in improving the soil, balancing nutrients, and increasing fertility. pH is a major factor affecting the effectiveness of mineral nutrients.

4, pay attention to the input of organic fertilizer. Every gram of orchard base fertilizer should be applied at least 5,000 kg of high-quality farmyard fertilizer, and be mixed with phosphate fertilizer and used after fermentation. Can also be taken to shred straw, wheat straw and other objects to cover, or a kind of clover and other green manure plants, through the measures of mowing and pressing, increase soil organic matter content, and enhance the soil to maintain fertilizer and water storage capacity.

5, pay attention to fertilization area and fertilization depth. Do not fertilize too close to the trunk. There is less absorption of roots around the trunk of the fruit tree, and the applied fertilizer is not easily absorbed and utilized by the tree, and it is easy to burn roots and cause fertilizer damage. The depth of fertilization should be treated differently depending on the season of fertilization. In the autumn, the depth should be 30-40 cm. In summer, it should not exceed 20 cm.
