Autumn is a critical period for the late field management of the apple orchard. According to the experienced fruit farmers, after the fruit is harvested, the effect of applying the base fertilizer to the apple tree is quite good. Fertilizers with the same quantity and quality can increase the fruit setting rate by 8-10% and increase the yield by 10-15% compared with the spring and winter application.
First, the benefits of applying base fertilizer to apple trees in autumn:
1. The nutrients consumed by the apple tree from the early spring germination to the flowering fruit are mainly the nutrients stored in the tree in the previous year. The period from the harvest of the fruit to the time before the fall is the best time to accumulate nutrients. The autumn base fertilizer can increase the nutrient reserve of the tree.
2. The temperature in winter and spring is low, and the decomposition of organic fertilizer is slow. During this time, organic fertilizer is applied and the fertilizer cannot be fully utilized. After the decomposition of fertilizers exerts fertilizer effect, it often causes the secondary growth and development of apple tree shoots, which will adversely affect the differentiation and fruit setting rate of apple tree flower buds, and the autumn base fertilizer will let you solve these problems as you wish.
3, autumn application of base fertilizer can improve the soil pores, so that the soil is loose, is conducive to apple orchard to protect water storage, prevent winter and spring drought, can also improve the ground temperature, prevent frost damage in the roots of apple trees.
4, autumn Shi base fertilizer, the small roots of the accidentally injured can quickly heal, but also promote new roots.
Second, the autumn Shi base fertilizer notes 1, organic, inorganic fertilizer combination. In the autumn, fertilization should be based on organic fertilizer, and combined with quick-acting fertilizers such as nitrogen, phosphorus and potassium. Before application, in the organic-based fertilizer, phosphorus phosphate such as superphosphate is firstly stacked together; when applied, a certain amount of quick-acting nitrogen fertilizer, such as urea, ammonium bicarbonate, ammonium sulfate, etc., is applied in combination.
2. Determine the time. Fertilization time varies depending on the species and variety. Generally, it is suitable before and after the autumn equinox (after the harvest in late September and mid-late varieties).
3. Determine the amount of fertilizer applied based on the results. The saplings are applied with 15-20 kg of manure or chicken manure and 1-2.5 kg of ammonium sulphate; the initial results are 100-150 kg of soil manure, 20-25 kg of human excrement or chicken manure; The production level determines the quantity of organic fertilizer; the general yield of 2000 kg per mu requires “jinjinjinfeiâ€; the per mu yield is 2500-3500 kg, which requires “six pounds and half fat†and combined with phosphorus and potassium fertilizer.
4. Determine the specific fertilization method according to the condition of the tree body and the soil fertility. (1) Ring fertilization: dig a 30 cm (width) 30 cm (deep) annular groove slightly outside the canopy, and apply the prepared organic fertilizer to cover the soil. This method is generally used for saplings. (2) Radiation ditch fertilization: Dig 30 (width) × 30 (deep) × 50 (length) cm of radiation ditch slightly outside the canopy, and cover the soil with fertilizer. This method can replace the radiation ditch every other year or every other time to expand the fertilization area. (3) Fertilization in the ditch: in the orchard line, between the plants or in the interlacing and ditching, it can also be combined with deep turning. (4) Fertilization in the whole garden: Adult trees or densely planted orchards, this method is used when the root system has been covered in the whole garden, and the fertilizer is evenly spread in the garden and then turned into the soil.
