Example II,
The special fertilizer for the Sauropus androgynus for improving the soil comprises 15 parts of organic fertilizer, 5 parts of lime nitrogen, 8 parts of calcium magnesium phosphate fertilizer and 3 parts of microbial inoculum by weight. The organic fertilizer comprises a commercial organic fertilizer and a farmyard manure, the commercial organic fertilizer meets the requirement specified in NY 525, and the farmyard manure is applied after being fully decomposed. The microbial inoculum is a microbial inoculum.
Example III,
The special fertilizer for the Sauropus androgynus for improving the soil comprises 30 parts by weight of organic fertilizer, 10 parts by weight of lime nitrogen, 10 parts by weight of calcium magnesium phosphate fertilizer and 5 parts by weight of microbial inoculum. The organic fertilizer comprises a commercial organic fertilizer and a farmyard manure, the commercial organic fertilizer meets the requirement specified in NY 525, and the farmyard manure is applied after being fully decomposed. The microbial inoculum is a microbial inoculum.
The above three groups of examples all adopt the following method
A method for applying a special fertilizer for Sauropus androgynus for improving soil comprises the following steps:
firstly, spreading lime nitrogen, deeply turning and irrigating, covering a mulching film, sealing for about one week, and then uncovering the film for airing;
step two, after 3 days, applying an organic fertilizer, a calcium magnesium phosphate fertilizer and a microbial inoculum, uniformly spreading and turning over, then covering a mulching film again, and paving a special drip irrigation pipeline;
thirdly, inserting the sapling vegetable seedlings according to the plant spacing of 50 cm and the row spacing of 60 cm, and watering enough rooting water;
after new leaves grow on the young vegetables, topdressing the high-nitrogen water-soluble fertilizer through an irrigation system for 1 month to obtain a spray irrigation system and spraying the high-nitrogen foliar fertilizer;
and fifthly, dressing once after thin dressing after 3 times of harvest of the sapling vegetable.
In the research, the effect of 50 users on the fertilizer and the application method is considered, and the scoring standard of the test items is as follows: the score of 5 is very satisfactory, the score of 4 is satisfactory, the score of 3 is general, the score of 2 is unsatisfactory, and the score of 1 is very unsatisfactory. The common group is fertilizers.
| Test items | Example one | Example two | EXAMPLE III | General group |
| Pathogenic bacteria | 4.9 | 4.6 | 4.7 | 3.0 |
| Salt content | 4.9 | 4.7 | 5.0 | 1.0 |
| Acidity and alkalinity of soil | 4.9 | 4.6 | 4.8 | 1.0 |
| Organic matter content | 4.9 | 4.7 | 4.6 | 1.2 |
