Embodiment 1
[0040] In the spring, the surface polysaline soil (the surface layer from the surface to the depth of 5mm, with a salt content of 3% and a pH value of 8.7) was taken from the soda saline-alkali land in Daan, Jilin, and the Suaeda salsa grown in the soda saline-alkali land was air-dried and then prepared in a carbonization furnace at 300°C. To obtain halophyte charcoal, lime powder is obtained by crushing lime purchased in the market. Mix surface polysaline soil, halophyte charcoal, and lime powder in a ratio of 50:30:20, and pass through a 3mm sieve to obtain an acidic soil conditioner. The apparent density of the prepared acidic soil conditioner is 0.86g / cm 3 , pH value is 8.7.
[0041] According to the application rate of 200kg / mu mixed with acidic soil, the indoor simulation experiment was carried out. The acidic soil used is the acidic soil from the surface of the agricultural greenhouse to the depth of 20cm, the pH value is 4.55, and the exchangeable acidity is 2.4cmol / ...
Embodiment 2
[0046]In the spring, the surface polysaline soil (the surface layer from the surface to the depth of 5mm, with a salt content of 5%, and a pH value of 8.8) was taken from the soda saline-alkali land in Daan, Jilin, and the Suaeda salsa grown in the soda saline-alkali land was air-dried and then prepared in a carbonization furnace at 400°C. To obtain halophyte charcoal, lime powder is obtained by crushing lime purchased in the market. Mix surface polysaline soil, halophyte charcoal, and lime powder in a ratio of 60:25:15, and pass through a 3mm sieve to prepare an acidic soil conditioner. The apparent density of the prepared acidic soil conditioner is 0.89g / cm 3 , pH value is 8.9.
[0047] According to the application rate of 250kg / mu mixed with acidic soil, the indoor simulation experiment was carried out. The acidic soil used is the acidic soil from the surface of the agricultural greenhouse to the depth of 20cm, the pH value is 4.55, and the exchangeable acidity is 2.4cmol...
Embodiment 3
[0052] In the spring, the surface polysaline soil (the surface layer from the surface to the depth of 5mm, with a salt content of 10% and a pH value of 9.1) was taken from the soda saline-alkali soil in Da'an, Jilin. To obtain halophyte charcoal, lime powder is obtained by crushing lime purchased in the market. The surface polymer saline soil, halophyte charcoal, and lime powder are mixed according to the ratio of 70:20:10, and passed through a 3mm sieve to obtain an acidic soil conditioner. The apparent density of the prepared acidic soil conditioner is 0.92g / cm 3 , pH value is 9.1.
[0053] According to the application rate of 300kg / mu mixed with acidic soil, the indoor simulation experiment was carried out. The acidic soil used is red soil from the surface of Changsha to a depth of 20cm, with a pH value of 5.46 and an exchangeable acidity of 4.6cmol / kg; the soil water content was controlled at 60-80% of the field water capacity during the experiment.
