[0074] Influence of a kind of microbial fertilizer containing chelated trace elements of the present invention on pepper quality
[0075] 1. Experimental design
[0076] The test crop is hot pepper, the variety is "Bulgarian hot pepper", the planting density is 3000 plants / mu; there are two treatments, 3 repetitions, and the area of the plot is 20m 2 , random block arrangement. The processing settings are as follows:
[0077] Treatment A: Custom fertilization, compound fertilizer (N-P 2 o 5 -K 2 (0=15-15-15) 60kg / mu;
[0078] Treatment B: 60 kg / mu of microbial fertilizer prepared according to the above-mentioned embodiment 3.
[0079] 2. Fertilization time and method
[0080] When applying base fertilizer for site preparation, 60 kg of compound fertilizer per mu was applied to test soil A, and 60 kg of microbial fertilizer per mu was applied to test soil B, and then ridges were formed. Select robust seedlings with uniform growth for uniform planting. The other basal...
