Embodiment 1
[0055] A compound improver for gleization soil, comprising the following components by weight:
[0056] 8 parts of quicklime; 23 parts of fly ash; 57 parts of fermented and decomposed cow dung; 12 parts of fermented and decomposed rapeseed dry cake. The four components are mixed evenly to make a compound improver.
[0057] The preparation method of the fermented and decomposed cow dung is as follows:
[0058] Mix fresh cow dung, grain bran and urea evenly in a weight ratio of 673:320:7, then add 0.5% of the total weight of the mixture as an organic material decomposing agent, and then adjust the moisture content to 55%, stack and ferment, every 2- Turn over once every 3 days, decompose after 15-20 days, and dry it for later use. The nutrient content of cow dung (fresh base) is N 0.40%, P 2 o 5 0.10%, K 2 O 0.23%.
[0059] The preparation method of the fermented and decomposed rapeseed dry cake is as follows:
[0060] Mix rapeseed dry cake and rice bran evenly at a weig...
Embodiment 2
[0063] A compound improver for gleization soil, comprising the following components by weight:
[0064] 5 parts of quicklime; 30 parts of fly ash; 50 parts of fermented and decomposed cow dung; 15 parts of fermented and decomposed rapeseed dry cake. The four components are mixed evenly to make a compound improver.
[0065] The preparation method of the fermented and decomposed cow dung is as follows:
[0066] Mix fresh cow dung, grain bran and urea evenly in a weight ratio of 645:350:5, then add 0.5% of the total weight of the mixture as an organic material decomposing agent, and then adjust the moisture content to 55%, stack and ferment, every 2- Turn over once every 3 days, decompose after 15-20 days, and dry it for later use. The nutrient content of cow dung (fresh base) is N 0.44%, P 2 o 5 0.13%, K 2 O 0.28%.
[0067] The preparation method of the fermented and decomposed rapeseed dry cake is as follows:
[0068] Mix rapeseed dry cake and grain bran evenly at a wei...
Embodiment 3
[0085] A compound improver for gleization soil, comprising the following components by weight:
[0086] 10 parts of quicklime; 20 parts of fly ash; 60 parts of fermented and decomposed cow dung; 10 parts of fermented and decomposed rapeseed dry cake. The four components are mixed evenly to make a compound improver.
[0087] The preparation method of the fermented and decomposed cow dung is as follows:
[0088] Mix fresh cow dung, grain bran and urea evenly in a weight ratio of 690:300:10, then add 0.5% of the total weight of the mixture as an organic material decomposing agent, and then adjust the moisture content to 55%, stack and ferment, every 2- Turn over once every 3 days, decompose after 15-20 days, and dry it for later use. The nutrient content of cow dung (fresh base) is N 0.35%, P 2 o 5 0.09%, K 2 O 0.19%.
[0089] The preparation method of the fermented and decomposed rapeseed dry cake is as follows:
[0090] Mix rapeseed dry cake and rice bran evenly at a we...
