Embodiment 1
[0027] This embodiment is a shatang orange orchard with more sand grains and stronger acidity, and the degree of yellowing is moderate. The improvement plan is: add 40kg of water to 50kg of fire-burned soil, 30kg of bio-organic fertilizer, and 13kg of slaked lime, mix evenly, pile up for 120 hours, turn over the pile, cool down to normal temperature, and then mix 7kg of compound microbial bacterial agent with it to obtain Composite improver. At the end of December 2009, choose sunny weather, pick all the fruits, thin out overlapping branches and cross branches, and cut off all branches with a diameter of less than 0.6 cm. Open a ditch near the drip line of the crown, the ditch is 20-25cm wide and 25-30cm deep, clean up the necrotic root system, and dry the ditch for a day. The next day, add 13kg / plant of improver and cover with soil. At the end of December 2010, the program was implemented again, and the dosage of the improver was not reduced due to the improvement of the ye...
Embodiment 2
[0031] This example is a tribute orange orchard with better soil texture and stronger acidity, and the degree of yellowing is serious. The improvement plan is: add 35kg of water to 45kg of fire-burned soil, 35kg of bio-organic fertilizer, and 10kg of slaked lime, mix evenly, pile up for 180 hours, turn over the pile, cool down to normal temperature, and then mix 8kg of compound microbial bacterial agent with it to obtain Composite improver. At the end of December 2009, choose sunny weather, pick all the fruits, thin out overlapping branches and cross branches, and cut off all branches with a diameter of less than 0.8 cm. Open a ditch near the drip line of the crown, the ditch is 20-25cm wide and 25-30cm deep, clean up the necrotic root system, and dry the ditch for a day. The next day, add 10kg / plant of improver and cover with soil. At the end of December 2010, the program was implemented again, and the dosage of the improver was not reduced due to the improvement of the yel...
Embodiment 3
[0035] Example 3 is a spring sweet orange orchard with relatively viscous soil and weak acidity, and the degree of yellowing is mild. Add 40kg of water to 60kg of fire-fired soil, 25kg of bio-organic fertilizer, and 15kg of slaked lime, mix evenly, pile up for 240 hours, turn over the pile, cool down to normal temperature, and then mix 5kg of compound microbial agent with it to obtain a compound improver. At the end of February 2009, choose sunny weather, pick all the fruits, thin out overlapping branches and cross branches, and cut off all branches with a diameter of less than 0.3 cm. Open a ditch near the drip line of the crown, the ditch is 20-25cm wide and 25-30cm deep, clean up the necrotic root system, and dry the ditch for a day. The next day, add 15kg / plant of improver and cover with soil. At the end of February 2010, the program was implemented again, and the dosage of the improver was not reduced due to the improvement of the yellowing degree.
