The fertilization time should be as early as possible in early autumn peach tree basal fertilizer in mid-September is appropriate, the soil temperature is higher during this period, the ability of root regeneration, root recovery quickly. At the same time, the conversion of fertilizer is fast, which is beneficial to tree absorption.
Fertilization appropriate Peach tree roots are mainly distributed in 20 ~ 40 cm soil layer, fertilization ditch or fertilizer hole depth of 30 ~ 40 cm is appropriate.
In the fertilization surface, the root system of P. philoxeroides should have higher oxygen demand than other fruit trees, and the fertilization area should be appropriately increased to increase the root absorption area, improve the root growth environment, and increase the root absorption function. Base fertilizers in production should be combined with soil amendments. The specific method is: dig fertilization along the periphery of the crown, the width of 40 to 60 cm, depth 30 to 40 cm, and pay attention to the location of fertilization year after year, usually 3 to 4 years to complete a soil improvement.
Peanut nutrient should be sufficient peach base fertilizer should be manure, cake-based, and with the application of fertilizer on demand. The results of the initial tree fertilization amount per acre Shi quality farmyard fertilizer 2000 to 3000 kg, mixed application of compound fertilizer 20 to 30 kilograms; fruit tree fertilization amount per acre Shi quality farmyard fertilizer 4000 to 5000 kg, mixed application of compound fertilizer 40 ~ 50 kilograms.
