The invention discloses a hydraulic deep and rotary cultivation powdery ridge machine which comprises a traveling gear, a cab, an engine, a powdery ridge machine and a framework. The cab and the engine are arranged on the framework, the traveling gear is mounted on the lower portion of the framework and is driven by the engine, a cutting disc which is driven by a hydraulic motor is arranged on the front lower portion of the framework, and the powdery ridge machine is connected to the rear of the framework by hinge seats and hydraulic cylinder supports. The hydraulic deep and rotary cultivation powdery ridge machine has the advantages that the hydraulic deep and rotary cultivation powdery ridge machine can travel stably, is simple and practical, is high in soil smashing efficiency and favorable for growth of roots of crops, deep soil loosening, surface soil loosening and soil lump smashing functions are integrated, deep soil drilling effects can be realized, and the oxygen contents of deep positions of soil and the yield of the crops can be increased.

The invention discloses a layered remediation method for chromium contaminated soil. The method comprises the following steps: detecting the actual chromium contamination condition of soil, determining the boundary of severe and mild chromium contaminated soil on soil depth, performing remediation on the severe chromium contaminated soil by adopting a chemical reduction stabilization method, performing remediation on the mild chromium contaminated soil by adopting a chemical or biochemical reduction stabilization method, performing soil conservation, balancing the soil acidity and alkalinity and performing later-stage tracking and monitoring. An actual chromium contaminated field serves as a support, the combined remediation methods are selected aiming at the current situation that the contamination degrees of the upper soil and the bottom soil are different, the severe chromium contaminated soil on the surface layer is subjected to remediation by adopting the chemical reduction stabilization method, the mild chromium contaminated soil on the deep layer is subjected to remediation by adopting the chemical or biochemical reduction stabilization method, the defects that the soil properties are not distinguished and a same remediation method is adopted in a unified mode in the previous research are overcome, and ex-situ remediation and in-situ remediation are combined to be used, so that the remediation method is reasonable in application under the condition that the remediation effect is guaranteed, the remediation cost is reduced, and the method can be applied to actual soil remediation on a large scale.

The invention discloses a method for manufacturing a standard capsule for plant seed sowing depth. The method comprises steps as follows: parameter design, product modeling, mold design, material mixing, putting of the mixture into a mold, compression molding, heating and airing, feeding of base fertilizer and seeds, capsule body sealing, pasting of two-dimensional codes, overall packaging. The seed capsule fully meets different soil depth standard sowing requirements of seeds, a wood bit substrate provides certain insulation and moisturizing effects, so that the seed budding rate and the survival rate of buds are increased, and the budding consistency is improved. Nitrogen, phosphorus and potassium fertilizer in a standard ratio in the substrate can provide the seeds with scientific nutrients, and the seed capsule can protect the seeds from being invaded by birds and other animals during the budding. Glutinous rice glue of the formed seed capsule is environment-friendly, breathable and permeable and can be degraded completely, rapidly and naturally, and all information and big data of the seeds and an internet entrance can be known in real time with the adoption of a two-dimensional code technology.
