Problems solved by technology

However, at present, there is not enough attention paid to the input of organic carbon in fruit tree production, and there is even a lack of soil fertilization methods with organic carbon as the core, and it is not clear what type and amount of organic carbon are suitable for apple orchard soil fertilization

Embodiment 1

[0026] It is planned to establish an apple orchard with a row spacing of 2×4m, and the row length of fruit trees is 100m, which is planned to be planted in mid-March. Draw the planting row in the first ten days of February, dig a planting ditch with a length of 100m, a width of 1.5m, and a depth of 90cm along the planting row, fill the ditch with sawdust, and sprinkle chicken manure when the thickness reaches 36cm, so that the separation of sawdust and chicken manure The overall thickness reaches 41cm, and then evenly sprinkle 350g of phosphate rock powder per 1m of the planting ditch in the planting ditch, stir and mix, and finally fill the ditch with soil and fill it with water. After 40 days, dig holes in the above-mentioned planting ditch to plant trees.

[0027] In the fall of the year when the apple trees were planted, a ring-shaped fertilization ditch was dug along the outer edge of the tree crown projection. During the fertilization ditch, 100kg of biochar with a carbon...

Embodiment 2

[0030] It is planned to establish an apple orchard with a row spacing of 3×5m, and the row length of fruit trees is 100m, which is planned to be planted in mid-March. Draw the planting row in the first ten days of February, dig a planting ditch with a length of 100m, a width of 2m, and a depth of 100cm along the planting row, and fill the ditch with corn stalks, and the thickness of the filling is 40cm; The overall thickness of corn stalks and cow dung reaches 50cm, and then 500g of phosphate rock powder is evenly sprinkled in every 1m of the planting ditch in the planting ditch, and finally the ditch is filled with soil and filled with water. After 40 days, dig holes in the above-mentioned planting ditch to plant apples Tree.

[0031] In the fall of the year when the apple trees were planted, a circular fertilization ditch was dug along the outer edge of the tree crown projection. During the fertilization ditch, 250 kg of biochar with a carbon mass fraction of 64% and 4750 kg...

Abstract

The invention discloses a method for carbon increasing fertilizing of soil in an apple orchard. The method comprises soil fertilization before planting, soil fertilization before fructification and soil fertilization after fructification and concretely comprises filling a planting trench with a plant material, animal feces and ground phosphate rock according to a ratio in least one month before apple tree planting, then filling the planting trench with soil, carrying out spreading, sinking and compaction, before an average fruit yield of apple trees is 10kg, applying organic carbon, compound microbial fertilizer and compound fertilizer or mixed fertilizer to the field according to a ratio in autumn every year, and after an average fruit yield of the apple trees is 10kg or more, applying humate and compound fertilizer or mixed fertilizer to the field according to different ratios by three steps every year. The method significantly increases apple orchard soil carbon content, improves soil fertility and soil health status, improves a carbon dioxide concentration and photosynthesis in the orchard, reduces the amount of fertilizer application and frequency of topdressing, and has good ecological and economic benefits.

Description

[0001] (1) Technical field [0002] The invention relates to a method for increasing carbon and fertilizing apple orchard soil, which belongs to the field of orchard soil fertilization. [0003] (2) Background technology [0004] Soil is the foundation of plant site and the basis of fruit tree cultivation. However, in production, the awareness of emphasizing fertilizer and despising soil, emphasizing output and despising input, and over-reliance on chemical fertilizers have led to insufficient input of organic matter in many orchards, and soil structure has deteriorated. Soil nitrogen is high and carbon is low, the ratio of carbon to nitrogen is unbalanced, and soil fertility generally declines, which seriously threatens the sustainable production of orchards. [0005] Fruit tree production should pay attention to both output and input, both inorganic matter and organic matter should be input. According to Liebig's nutrient return theory, to maintain soil fertility and crop yi...
