The utility model relates to the field of pomegranate planting fertilization discloses a kind of pomegranate planting fertilization device, including cart, the top of the cart is provided with irrigation assembly, the irrigation assembly includes storage cylinder, the storage cylinder is fixedly connected in the top of cart near left side position, the top of the cart is fixedly installed with water suction pump near the right side of storage cylinder, the water suction pump is communicated with the inside of storage cylinder by connecting pipe, the top of the cart is fixedly installed with delivery pipe above water suction pump, the delivery pipe is also communicated with each other by connecting pipe with water suction pump, the top of the delivery pipe is provided with multiple groups of connecting hose. In the utility model, liquid fertilizer is simultaneously fertilized by multiple spray heads, improving the efficiency of fertilization, multiple spray heads are adjusted, the direction of fertilization can be accurately controlled, the fertilization range is expanded, the uniformity of fertilization is ensured, the fertilization area per unit time is improved, and the uniform distribution of fertilizer is ensured.

The invention discloses a preparation method of a controlled release organic fertilizer special for eucalyptus, which comprises the following steps: uniformly mixing decomposed farmyard manure, compound fertilizer, clay, borax and zinc sulfate according to the nutritional requirements of the eucalyptus in different growth stages to obtain a base fertilizer; the preparation method comprises the following steps: mixing urea, monoammonium phosphate, calcium superphosphate, potassium chloride, clay, manganese sulfate, diammonium phosphate, potassium sulfate, magnesium potassium sulfate, borax, zinc sulfate and other raw materials according to different proportions, granulating, and respectively spraying with a polyurethane coating liquid and an epoxy resin coating liquid, polyurethane coating layers and epoxy resin coating layers with different thicknesses are sprayed on the through holes to obtain slow release fertilizers with different slow release periods, the slow release fertilizers with different slow release periods are mixed in proportion and then applied to planting holes at one time when eucalyptus is planted, and the slow release fertilizers are released in different growth periods of the eucalyptus; the proportion of various nutrient substances is regulated and controlled to meet the nutritional requirements of the eucalyptus in different growth stages, so that the fertilization frequency is greatly reduced, and the problem that the fertilization cost is relatively high is solved.

The invention discloses an agriculture and forestry compound management method with eucalyptus and commercial crops as main components, and the method specifically comprises the following steps: S1, forest land site selection and pretreatment: selecting a laterite / laterite forest land with the altitude less than or equal to 800m and the PH value of 4.5-6.5, and relates to the technical field of agriculture and forestry compound management. According to the agriculture and forestry composite management method with eucalyptus and commercial crops as main components, medicinal plants such as honeysuckle, rhizoma polygonati and anoectochilus formosanus are accurately matched according to microenvironment characteristics of eucalyptus in different growth stages, the content of effective components of various medicinal materials is remarkably increased by combining a medicinal component directional regulation and control technology, and the effective components meet the high-quality standard of pharmacopoeia; compared with a traditional mode, the annual average yield per mu income of medicinal plants and the land resource utilization rate are greatly improved, the nutrient requirements of eucalyptus in all growth stages are met through intelligent drip irrigation and staged water and fertilizer management, the application of biological bacterial fertilizer and organic fertilizer is matched, the soil structure is effectively improved, the eucalyptus growth speed and the wood yield are remarkably improved, and the phenomenon of small old trees is avoided.

This invention discloses a slow-mixed fertilizer suitable for increasing yield and reducing emissions in machine-transplanted early rice in low-latitude regions. It consists of the following parts by weight: 4-6 parts sulfur-coated urea and 4-6 parts 2-month resin-coated urea. The invention also discloses the application of this slow-mixed fertilizer in early rice production, with fertilization carried out simultaneously with rice transplanting. The slow-mixed fertilizer is applied directly to the base of the seedlings at a depth of 5 cm and 3-5 cm in the soil. This invention's slow-mixed fertilizer can increase yield, nitrogen fertilizer use efficiency, and reduce greenhouse gas emissions. Compared with conventional high-yield, multi-stage fertilization, the application of this invention's slow-mixed fertilizer increases rice yield by 7.5%-7.8%, increases nitrogen fertilizer use efficiency by 30.5%-44.5%, reduces global warming potential by 12.8%-27.5%, and reduces greenhouse gas emission intensity by 19.3%-32.7%.
