【Longpu】Benefits and precautions of fertilization in autumn orchards
The nutrients consumed by fruit trees during the period from early spring germination to flowering and fruiting are mainly the nutrients stored in the trunk in the previous year. The period from fruit harvesting to leaf dropping is the best time to accumulate nutrients, and autumn fertilization can increase the tree's nutrient reserves.
The benefits of autumn fertilization
1. Autumn is the period of nutrient accumulation for fruit trees, and the aboveground parts have basically stopped growing. However, photosynthesis on the leaves is still vigorous, which is conducive to accumulating more nutrients on the leaves and transporting them to the stems and branches.
2. Fertilization in autumn can increase soil porosity, loosen the soil, and help moisture retain and prevent winter and spring droughts. It can also increase soil temperature and prevent root freezing damage.
3. Improve the root growth environment and enhance the tree's stress resistance. Combining autumn fertilization and deep plowing of soil can optimize soil structure, improve soil permeability conditions, facilitate root respiration and growth, enhance soil water storage, fertilizer retention, and winter resistance.
4. Autumn is the peak period for the growth of fruit tree roots. At this time, the small tree roots damaged by fertilization can quickly heal and promote the quick growth of new roots, thereby increasing the number of roots that absorbing nutrients, expanding the absorption area, and greatly improving the utilization rate of fertilizers.
Precautions for fertilization in autumn
1. Fertilization in autumn should achieve a reasonable combination and balanced nutrition;
2. The process of replenishing water also needs to be followed up synchronously, as the combination of water and fertilizer is more conducive to improving fertilizer efficiency;
3. Adopt scientific fertilization methods;
4. Choosing fertilizers requires products from reputable manufacturers with sufficient content to ensure effective fertilization.
Longpu collagen peptide humic acid water-soluble organic fertilizer is prepared through patented technology, which is rich in 19 kinds of amino acids of collagen peptide that plants needed and various bacillus such as withered grass, lichen, and giant, macro-element and medium-elements required by plants, such as nitrogen, phosphorus, potassium, calcium, sulfur, magnesium, etc. Longpu collagen peptide humic acid water-soluble organic fertilizer achieves a suitable nutritional combination, which can meet the needs of this period. When combined with collagen peptide foliar fertilizer and high calcium fertilizer, it has a better effect and can comprehensively adjust the nutritional requirements of fruit trees, making fruit robust and high-quality.
