Embodiment 1
[0030] In 2010 and 2014, a small excavator was used to clear the litchi garden in Guangzhou, and a soil improvement pit was dug under the same litchi tree drip line, and the soil improvement pit was about 1m away. 3 The litter, fallen leaves and weeds were filled into the soil improvement pit and covered with 5cm of soil. In January 2018, 50-70cm deep soil and the orchard ladder wall were excavated from this position (if the orchard is on flat ground, the uncultivated garden is selected, compared with ) each 2500g of soil was tested. The test results are: the organic matter content of the improved soil is 75.5g / kg, the total nitrogen content is 0.278%, the available phosphorus is 16.2mg / kg, the available potassium is 75.1mg / kg, and the soil pH value is 5.6; the organic matter content of the control soil The total nitrogen content is 16.3g / kg, the total nitrogen content is 0.084%, the available phosphorus is 3.7mg / kg, the available potassium is 46.6mg / kg, and the soil pH value ...
Embodiment 2
[0032] In 2011 and 2015, a small excavator was used to clear the litchi garden in Guangzhou, and a soil improvement pit was dug under the same litchi tree drip line, and the soil improvement pit was about 0.8m away. 3 The litter and weeds were filled into the soil improvement pit and covered with 5cm of soil. In January 2018, 50-70cm deep soil and 2500g of orchard ladder wall (control) soil were excavated from the soil improvement pit for testing. The test results are: the organic matter content of the improved soil is 34.2g / kg, the total nitrogen content is 0.152%, the available phosphorus is 12.9mg / kg, the available potassium is 44.4mg / kg, and the soil pH value is 5.6; the organic matter content of the control soil The total nitrogen content is 16.3g / kg, the total nitrogen content is 0.084%, the available phosphorus is 3.7mg / kg, the available potassium is 46.6mg / kg, and the soil pH value is 4.5. According to the soil nutrient grading standard of the second national soil cens...
Embodiment 3
[0034] In 2013 and 2017, a small excavator was used to dig a soil improvement pit under the drip line of the Litchi Garden in Guangzhou, and the soil improvement pit was approximately 1.2m away. 3The litter and weeds were filled into the soil improvement pit and covered with 5cm of soil. In January 2018, 2500g of soil at a depth of 50-70cm and 2500g of soil on the orchard ladder wall (control) were excavated for testing. The test results are: the organic matter content of the improved soil is 23.6g / kg, the total nitrogen content is 0.105%, the available phosphorus is 9.6mg / kg, the available potassium is 29.1mg / kg, and the soil pH value is 5.3; the organic matter content of the control soil The total nitrogen content is 16.3g / kg, the total nitrogen content is 0.084%, the available phosphorus is 3.7mg / kg, the available potassium is 46.6mg / kg, and the soil pH value is 4.5. According to the soil nutrient grading standard of the second national soil census, the soil after improveme...
