Abstract: In this paper, biological organic formula fertilizer was applied in sisal field for two consecutive
years instead of traditional chemical fertilizer. Three treatments were set up: Conventional fertilization (CK),
application of 1/2 conventional fertilization + sisal bio-organic formula fertilizer 125 kg/hm2 (T1) and sisal
bio-organic formula fertilizer 250 kg/hm2 (T2) were used to study the effects of continuous bio-organic formula fertilizer on soil nutrients, microbial biomass carbon and nitrogen, enzyme activity, leaf growth and
yield of sisal. The results showed that continuous application of bioorganic formula fertilizer (T2) promoted
the absorption and utilization of calcium in sisal plants, the total calcium content of sisal leaves was 0.67 mg
/ kg higher than that of traditional chemical fertilizer, and the fiber content of sisal leaves was 0.35 mg / kg
higher than that of traditional chemical fertilizer. At the same time, compared with conventional fertilization
(CK), sisal applied bioorganic formula fertilizer (T2), effectively improved soil microbial biomass carbon
and nitrogen content, sucrase activity, urease activity, catalase activity and soil quality, reduced the input cost
of chemical fertilizer, and avoided excessive application of fertilizer. In two years, T2 increased its income
by 2400.5 yuan/hm2 compared with CK, and T1 increased its income by 663 yuan/hm2 compared with CK,
providing an effective way to promote the healthy and sustainable development of sisal industry.
