Embodiment 1
[0019] Flower pot experiment: set up 4 treatment groups, respectively:
[0020] ①Blank group: without adding any modifier;
[0021] ② Quicklime group: the addition amount is 6g / kg (soil);
[0022] ③ Superphosphate group: the addition amount is 2 g / kg (soil);
[0023] ④ Buffer solution group: apply the buffer solution with a pH value of 7.0 prepared with phosphorus and potassium fertilizers and sodium hydroxide in the above table 1, and the dosage is 250ml / kg (soil) (equivalent to about 5 L / m 2 ).
[0024] Experimental soil: collected in Aoping Town, Pengzhou City, Sichuan Province. First, the collected soil was air-dried to remove impurities and mixed evenly, and the original pH value was measured to be 5.52. Then put the above soil into flowerpots at 8kg / pot, add the modifiers of groups ②~④ respectively, then add water to each pot to 70% of the field water holding capacity, and cultivate at 25±1℃ for 60 days, every 3 days at least Weighing method replenishes evaporated w...
Embodiment 2
[0029] Field test with buffer application: the test land area is about 28.2m 2 , divided into 4 plots: the blank group, and the others are treatment groups. 30 days before the planting of Chuanxiong, in the planting soil with the original pH value of 6.04, press 750kg / hm 2 Apply quicklime and mix evenly; start 30 days after the Rhizoma Chuanxiong is planted, and water the phosphate buffer solution with pH 6.5 and pH values 7.0 and 7.4 in Table 1 respectively to the plots of each treatment group within 6 months. 5.3L / m 2 , labeled as buffer 1 group, buffer 2 group and buffer 3 group, respectively. Table 3 shows the change results of soil pH value measured at different times.
[0030] Wherein, the composition of the pH6.5 phosphate buffer is as follows: take 0.68g of potassium dihydrogen phosphate, add 15.2ml of 0.1mol / L sodium hydroxide solution, and dilute to 100ml with water to obtain; the phosphate buffer (pH7.0 ): Take 0.68g of potassium dihydrogen phosphate, add 29.1...
Embodiment 3
[0035] Tests on plant damage by applying different soil amendments: A typical acidic Rhizoma Chuanxiong planting soil was selected in Aoping Town, Pengzhou City, Sichuan Province for field experiments, and 3 treatments were set up, namely:
[0036] ① Blank group: without adding any modifier;
[0037] ② Quicklime group: Before the Rhizoma Chuanxiong was planted, the facing area was about 28.2m 2 2.12kg of lime (equivalent to 750 kg / hm 2 amount), turn the ground and mix;
[0038] ③ The present invention uses quicklime+buffer solution group: 30 days before the Rhizoma Chuanxiong is planted, press 750kg / hm in the soil with the original pH value of 6.04 2 Apply quicklime in proportion and mix; start 15 days after planting Ligusticum chuanxiong, and spread to an area of about 28.2 m per month 2 Add 150L of buffer solution (equivalent to 5.3L / m 2 dosage). Calculate the emergence rate of Rhizoma Chuanxiong after emergence.
[0039] Experimental result: 1 month statistics dead ...
