Problems solved by technology

[0005] However, the strawberry fertilizers in the prior art often have complex compatibility, and the slow-release effect of fertilizers is often achieved through slow-release agents or special materials, and the process of soil consolidation and oxygenation is achieved through chemical reagents. Long-term use will inevitably cause certain environmental problems to the soil. impact, seriously destroying the soil structure, so as to hinder the sustainable development of agriculture, none of the above inventions have fundamentally solved the problems in the growth process of strawberries, and the cost of fertilizers is high, it is difficult to achieve high fertilizer efficiency to promote strawberry growth and obtain high returns Effect

Embodiment 1

[0034] Preparation and Application of Embodiment 1 Special Fertilizer for Strawberry

[0035] Weigh 450 parts of fermented black soldier fly manure, 450 parts of unfermented Tenebrio molitor manure, 5 parts of urea, 10 parts of diammonium phosphate, 8 parts of potassium sulfate, and 55 parts of vermiculite and mix well.

[0036] Fermentation method of black soldier fly dung: add black soldier fly dung or Tenebrio molitor dung to water, adjust the water content to 55%, seal and stack for 8 days, and turn the pile once in the middle of fermentation;

[0037] Among them, the vermiculite is expanded vermiculite with a particle size of 1-3mm.

[0038] Apply the special fertilizer prepared above into the ground within 1 week before strawberry transplantation as a base fertilizer and plow it evenly. The amount of fertilization is 3 kg / mu once, and the amount of high-potassium fertilizer (15:4:37) for topdressing during the fruit expansion period and the entire fruiting period is 3 kg / ...

Abstract

The invention relates to a special fertilizer for strawberry by using worm excrement as a matrix and a preparation method and application thereof. The special fertilizer for strawberry is prepared from the following raw materials in parts by weight: 400 to 500 parts of black soldier fly worm excrement, 400 to 500 parts of yellow mealworm worm excrement, 5 to 6 parts of urea, 10 to 15 parts of diammonium phosphate, 6 to 8 parts of potassium sulfate, and 50 to 60 parts of vermiculite. The special fertilizer for strawberry has the advantages that the special fertilizer is used as a base fertilizer for the strawberry growth, the soil can be effectively improved, the survival rate of the strawberry is improved, the salt diseases due to excessive fertilizer applying can be prevented, the fertilizer re-applying times and amount are reduced in the later stage, and the output and quality of the strawberry are improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a strawberry special fertilizer with insect manure as a substrate, a preparation method and application thereof. Background technique [0002] Strawberries are perennial herbaceous plants. The choice of soil conditions for strawberries is not very strict, and they can grow on various types of soil, but to achieve high yield and high quality, they should be cultivated on loose, fertile, and well-ventilated soil. Strawberry growth needs nitrogen, phosphorus, potassium, boron, magnesium, zinc, iron, calcium and other medium and trace elements. Among them, the absorption of potassium and nitrogen is extremely strong after the fruit enlargement period, but the absorption of phosphorus is very important in the whole growth process. Both are weak, and excessive phosphorus will reduce the gloss of the fruit. At the same time, strawberries are not resistant to fertilizer...
