How to fertilize garlic? What fertilizer?
1. Principle of fertilization: Garlic fertilization should be based on the soil fertility level and the needs of garlic at different fertility stages to apply scientific and rational fertilization, and grasp the fertilization principle of “before light weight, medium weight, and afterfillâ€. It is necessary to prevent pre-prosperity and avoid late stages. Deferring premature aging. 2. Fertilization for soil preparation: before planting, garlic should be combined with soil preparation for one-time application of base fertilizer at a rate of 2500 to 3,000 kg per hectare of farmyard fertilizer, 40 to 75 kg of chlorine-based compound fertilizer, and ferrous sulfate, manganese sulfate, borax, and zinc sulfate. Each 1.5 to 2 kg of copper sulfate. 3. Fertilizer for the application of fertilizers: Garlic is normally not managed in the field when the climate is normal. The first topdressing should be carried out at the jointing stage, and 20-25 kg of nitro compound fertilizer can be harvested at intervals of 15-20. The second day after the second fertilizer, Mushi amount of about 20 kg. 4. Differentiated fertilizer: Garlic enters differentiation and bolting period, and vegetative growth and reproductive growth are carried out at the same time. Demand for phosphorus is strong. Wait until the garlic sprouts out of the head (the current tail) and chase the high-phosphorus high-potassium compound fertilizer 15 to 20 kg. Redushing. 5, outside the root dressing: Garlic root dressing should be carried out before 11 o'clock in the morning or after 4 o'clock in the afternoon, use 2 grams of calcium sulfate or sulfur-based compound fertilizer 1 kg of watered 50 kg soaked for 12 hours, take the clear liquid spray 1 Mu, in the middle and late period can be 1 to 2 times foliar spray fertilizer.

PHB is a truly biodegradable and biocompatible plastic and an attractive environmental-friendly alternative to fossil-based thermoplastics such as PE and PP. However, unmodified PHB resin has a relatively high melting point of about 160 to 180 °C and is difficult to process due to its narrow processing window. To improve its processability and mechanical properties, PHB is often blended with plasticizers and other polymers such as polyvinyl acetate (binders), polyvinyl alcohol and polylactic acid (PLA).
Commercial grades of PHB have properties that are very similar to those of polypropylene (PP). Typical applications of PHB are disposable tableware articles like drinking cups, cutlery, trays, food plates and food containers. Some other (potential) applications include soil retention sheething and other agriculture films, waste and shopping bags, and the use as a packaging material in general. PHB can also be spun into fibers which could be used for the manufacture of woven and non-woven biodegradable one-use fabric articles such as surgical sutures (Tepha). Other (potential) biomedical applications include drug delivery systems (microcapsules or microspheres) and biodegradable implanted medical devices.
