Fruit tree deciduous use

In production, most fruit farmers clean the leaves in the garden to the outside of the park for the purpose of reducing the occurrence of pests and diseases in the coming year. This method also has its shortcomings. If it can be combined with fertilization, it will be better to concentrate the deciduous leaves.

Although some leaves are damaged by pests and diseases in the leaves, as long as they can be combined with fertilization to bury the leaves in the soil, they can effectively kill the pests and diseases, and thus will not cause the spread of pests and diseases. The leaves are also rich in nutrients that complement the various elements necessary for fruit tree growth.

According to the determination, a nitrogen-containing apple leaf 3--6% phosphorus 0.2 - 0.3%, 2% potassium and trace elements; Pear leaf nitrogen 2 - 2.2%, phosphorus 0.l - 0.25%, potassium l.2 — 2.6 %. Under normal circumstances, after the fruiting period, the nitrogen contained in all the leaves of each pear garden is equivalent to 98 kg of ammonium bicarbonate 12 kg of superphosphate and 20 kg of potassium carbonate, which can provide certain nutrients for the growth of fruit trees. Moreover, when the fruit leaves are applied to the soil as fertilizer, the soil can be well improved, the organic matter content in the soil can be increased, the soil ventilation condition can be improved, the soil fertilizer and water retention capacity can be improved, and the pH of the soil can be adjusted.

It can be seen that the leaves do not have to be cleaned out of the garden. As long as the method is properly used, it should be said that it is a good organic fertilizer on the spot. However, when using it, it must be combined with deep turning to apply it to the soil to avoid the spread of pests and diseases.
