Time to early peach autumn basal usually in mid-September is appropriate, the soil temperature is higher during this period, root regeneration ability, fast root recovery. At the same time, the conversion of fertilizer is fast, which is beneficial to the absorption of the tree and can increase the storage nutrients of the tree.
The root depth of Peach trees is mainly distributed in 20-40 cm soil layer, and the depth of fertilization ditch or fertilizer hole should be 30-40 cm.
The apical aerobic properties of the broad-spectrum Peach tree were better than that of apples and other fruit trees. The fertilization area should be increased, the root absorption area should be enlarged, the root growth environment should be improved, and the root absorption function should be improved. Base fertilizers in production should be combined with soil amendments. The specific approach is to dig fertilization ditch around the circumference of the tree crown. The width of the ditch is 40-60 cm and depth is 30-40 cm. Note that the fertilization location should be rotated year by year, and the soil improvement is usually completed in 3-4 years.
Nutrients should be full of peach base fertilizer should be manure, cake fertilizer and other organic fertilizers, in addition to organic fertilizers, should be used with inorganic fertilizers, accounting for the annual inorganic fertilizer dosage of 1/3-2/3, especially phosphate fertilizer, should be mainly for Base fertilizer application. And according to the nutritional status of the tree, with a certain amount of micro-fertilizer.
The basal fertilizer should have a higher percentage of fruit set in the peach tree and higher soil nutrient requirements. General results The amount of fertilization at the initial stage is: 2000-3000 kilograms of high-quality farmyard fertilizer per acre and 20-30 kilograms of compound fertilizer; the fertilization amount of trees in full fruit period is: 4000-5000 kilograms of high-quality farmyard fertilizer per acre, mixed and applied. 40-50 kg fat.
