Preparation and fertilization technology of organic blueberry production fertilizer

[0010] In order to make it easy to understand the technical means, creative features, work flow, and use methods of the present invention to achieve the purpose and effect, the present invention will be further described below in conjunction with examples.

[0011] The fertilizer preparation and fertilization technology for blueberry organic production includes the following steps: (1) Preparation of organic matter: ① farm animal and poultry manure using mountain weeds and crop orange stalks as food; The ratio of oiled cake manure, manure and cake manure is 10:1; (2) Stacking and fermentation: The prepared manure and crushed cake manure are piled up in layers for initial fermentation. The thickness of the manure is 30cm, the second layer is cake fertilizer, each layer is 2cm, stacked and fermented alternately, the ratio of manure and cake fertilizer is 10:1, and the volume of each pile is controlled at 6m 3 , the height is controlled at 1.5m, and then covered with plastic film to avoid rain and ferment, and drainage ditches are excavated around for waterproofing. After 30 days of initial fermentation, the compost is turned over, and the compost after initial fermentation is turned over, and the manure and cake fertilizer are initially mixed. , and then piled up to avoid rain and ferment, after 30 days to ferment again, that is, the composted manure can be completely decomposed and mixed for use; (3), fertilization technology: ①Ditching: excavate on both sides of the plant along the vertical line outside the crown of the plant Strip ditch or circular ditch, each ditch is 30-35cm deep and 25-30cm wide. ②Fertilization: Apply fermented and mixed organic fertilizer and the soil taken out of the excavated fertilization ditch alternately in layers and backfill in the ditch All the soil taken out from the ditch should be backfilled into the ditch. The amount of fertilizer per plant depends on the age and vigor of the tree. Generally, the amount of fertilizer per plant in the first 3 years after planting is 3-5kg, and after 5 years. The amount of fertilizer used per plant is 7-10kg, and the fertilization time is in late autumn or early spring.
