Biogas fertilizer contains many nutrients such as organic matter, amino acids, humus, nitrogen, phosphorus and potassium, as well as auxin and antibiotic substances. Most of the bacteria and eggs have been killed. It is an ideal non-polluting fertilizer with no pollution. High efficiency, fertility and other advantages. Application of biogas fertilizer to fruit trees can not only improve the soil, improve soil water conservation and drought resistance, but also enhance the photosynthesis of fruit trees, promote flower bud formation and flower protection, promote consistent fruit ripening, enhance tree vigor and improve the ability of the tree to prevent freezing and cold. , In order to achieve the effect of increasing production and quality. Biogas fertilizers include biogas slurry and biogas residues. The main application techniques are as follows:
I. Application of Biogas Residue Biogas residue refers to the bottom sediment after the anaerobic fermentation of organic matter such as human and animal feces, etc., which is mainly used as a base fertilizer. The specific application method is as follows: After mixing the biogas residue, straw, soil, etc. Apply early after harvesting fruit every autumn. The mature tree adopts radial guttering, ie, ditching along the crown of the canopy, the depth of the ditch is 0.2-0.4 meters, the width is 0.3-0.4 meters, the depth is shallow and the depth is 50 kilograms. Calcium phosphate 1.5 kilograms; Saplings can be combined with an expansion hole using a circular furrow. The ditch should not be too deep. Generally, the furrow depth is 0.15-0.35 meters, and the width is 0.2-0.3 meters. . Pay attention to less damage to the root system during fertilization and change the fertilization location each year.
Second, the application of biogas slurry Biogas slurry refers to the biodegradation of the fermented material in the biogas digester and forms a bright brown liquid. It is mainly used as a root topdressing fertilizer and foliar fertilizer.
(1) The top-dressing can be applied with ring-shaped groove method, that is, digging 10-15 cm shallow ditch on the outside of the canopy drip line. Before use, the biogas slurry should be diluted 2-3 times with clear water to prevent excessive concentration and burn the root system, usually 10 days before fruit tree sprouting, and fertilize with biogas slurry with 2 kg of water per plant; after new shoots are drawn For 15 days, 3 kg of biogas slurry was applied to each plant. During the growth of the young trees, the slurry was applied once every half month or 1 month.
(2) The foliar dressing biogas slurry should be extracted from the normal biogas production pool for more than one month, and be clarified and filtered to prevent plugging of the sprayer nozzle. The spraying time is preferably after the morning dew is dry (about 10:00 am). It is advisable to use it in the early evening in the summer. Do not spray at high noon and heavy rain before noon, and spray the leaves back to facilitate absorption. The specific spraying frequency and concentration should be determined according to the growth period and season of the fruit trees. The general principle is that the seedlings, young leaf stage 1 part of biogas slurry plus 1-2 parts of water, the summer high temperature season 1 part of biogas slurry plus 1 part of water, When the temperature is low and the old leaves are still fresh, no water is added.
The medical compressed air plant consists of the air compressor, general filter, aftercooler, precision filter, desiccant air dryer, air buffer tank, activated carbon filter, compressed air quality monitor, decompressor, valve, pipeline and terminal. The system generates compressed air through an air compressor, removes the impurities, oil mist and moisture in the compressed air through an adsorption dryer filter unit, delivers the air to the air storage tank and supplies it through a pipeline to the terminal equipment in the operating room, ICU and other inpatient wards after decompression.
