Orchard Nutrient Management in Autumn
Autumn is one of the most critical periods for fruit tree nutrient supplementation. It is mainly divided into two aspects. One is autumn basal fertilization and the other is extra-root topdressing. Autumn basal fertilization has the following advantages: First, it is beneficial to improve the nutrient storage of the tree and coordinate the relationship between vegetative growth and reproductive growth. The available nutrients in fertilizers are easily absorbed by the roots that are in the third growth peak, enhancing the function of autumn leaves and accumulating more nutrients, making the buds full and full, and the late flower buds developing well, laying the foundation for flowering and fruiting in the coming year; After a long period of decomposing, the delayed nutrients are gradually absorbed and used in spring to improve the quality of short and mid-stems, and to encourage spring shoots to stop in time to create conditions for flower bud differentiation. The second is that it is conducive to the renewal of the root system and the enhancement of nutrient absorption and synthesis. Early autumn roots are at the last peak of growth. The roots of the wounds are easily healed and restored, which is conducive to the initiation of new roots and is mostly effective in root absorption. The third is to increase soil temperature, maintain moisture, and enhance the ability of the tree to withstand cold in winter. The fourth is to avoid long shooters and cause shoots to “dry out†or saplings to “dry.†It is generally believed that an orchard with an applied amount of organic fertilizer (farmer manure) of more than 1,000 kilograms per mu should reach 1.5 kilograms per kilogram of apples; an annual output of 2,000 kilograms per kilogram should reach the standard of 1 kilogram of apples and 2 kilograms of mandarin. , At the same time with a small amount of quick-acting fertilizer. Fertilizer can be applied to organic orchard-deficient orchards. Fertilizers outside roots: Autumn is the period of fruit ripening. To improve fruit quality, increase coloration, increase sugar content, cleanse noodles, and reduce water and heart disease, bitter pit disease, and other deficiency factors, this period should grasp the critical period of fruit tree management. Extra-root fertilizer, this period is dominated by potash and calcium fertilizers. Can be sprayed and painted dry. When spraying leaves, we can choose Pudejin humic acid potassium fertilizer 800~1000 times to increase calcium 2000~2500 times or Gales 400~600 times or Stekoop 8000~10000 times. It is worth noting that apple fruit is very sensitive to calcium, and the mobility of calcium is poor. When calcium is added, it must be sprayed on the fruit surface. In strict accordance with the use multiple, do not arbitrarily increase the concentration. It can be used 15-30 times for Putong Jin when it is dry. It can also effectively prevent rot disease while supplementing potash fertilizer. After fruit-picking, the spraying of foliar fertilizer before defoliation can significantly increase the storage and nutrition of fruit trees. Spraying fruity amino acids or urea before falling leaves is very important for increasing tree nutrients. It has been proved that 600-fold of fruit-friendly amino acids or 1% of urea liquid can be sprayed on the foliage about 600 months before harvest to extend the lifespan of the leaves, enhance the function of the leaves, increase the photosynthetic intensity by 0.5 to 1 times, and improve the root system. Nutritional status, promote root development, enhance absorption capacity and overall metabolic process of fruit trees. The most important is to promote the reflux of nitrogen from the leaves to the tree and roots, thereby increasing the content of organic nitrogen in the tree.
