Embodiment Construction

[0025] Corn-peanut field fertilizer comparative test, the test site is the Longshan Experimental Base of the Maize Research Institute of Shandong Academy of Agricultural Sciences, the test period is from 2010 to 2012, and the test variety is Ludan 818. Test plan: apply the new special fertilizer for fertilizing corn of the present invention during one growth period of corn, the application rate is 40 kg / mu, and apply it at one time when sowing. The control is local conventional fertilization: apply compound fertilizer at one time when sowing 50 kg / mu (N:P 2 o 5 : K 2 O = 18:12:15), topdressing urea 10 kg / mu in the bell mouth stage.

[0026] Compared with local conventional fertilization, applying the new formula fertilizer corn special fertilizer of the present invention helps to improve the yield components, can increase the number of grains per spike, bulk density and thousand-grain weight by 1.76%, 1.56%, and 4.05% respectively, and increase production by 11.99%. It can...

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to a formula of a special fertilizer for corn under the condition of corn and peanut intercropping and a preparation method thereof. Background technique [0002] For a long time, in order to ensure food security and meet people's growing needs, a large amount of chemical fertilizers have been invested in agricultural production in my country, resulting in low utilization rates of chemical fertilizers, increased pesticide residues, serious farmland pollution, and deterioration of the agricultural ecological environment. For this reason, how to increase food production, reduce the amount of chemical fertilizers and pesticides used, and achieve environmentally friendly and sustainable agricultural development has become an urgent problem to be solved. Intercropping is the essence of traditional agriculture in my country and has a long history. Reasonable intercropping mode can no...
