This invention discloses a method for preparing a rice seedling substrate based on rice and wheat straw, its products, and applications. This application converts rice and wheat straw into earthworm castings, optimizes the earthworm castings, and prepares a rice seedling substrate more suitable for rice seedling cultivation practices in the middle and lower reaches of the Yangtze River. The water retention capacity of this seedling substrate is significantly superior to that of general seedling substrates. When using the "running water" irrigation method, it can continuously supply water to the seedlings even without timely irrigation, ensuring robust root growth; it can continuously control the pH of the seedling substrate, significantly improving the seedling's root development; and it can increase nutrient retention, ensuring the formation of strong seedlings.

The present application relates to intervertebral fusion holder medical instrument technology field, specifically speaking, a kind of holder and holding method, the holder includes screw rod, inner sleeve, outer sleeve, knob, locking block, the front end of the outer sleeve is equipped with with the inner support block of fusion ware middle clamping connector, the outer sleeve is equipped with inner sleeve, inner sleeve and outer sleeve sliding do not rotate connection, inner sleeve rear end stretches out outer sleeve and is connected with knob screw, the rear end surface of inner sleeve is equipped with fixed tooth, screw rod is inserted into inner sleeve, the front end of screw rod stretches out outer sleeve, the rear end of screw rod stretches out inner sleeve and is equipped with locking block, the front end surface of the locking block is equipped with with the locking tooth of fixed tooth meshing, by the assembly of holder, fixed inner support block, fixed outer expansion block, locking, inner support block advance, disengage, bone grafting etc. Step is used, with simple structure, holding effect is good, holding operation is simple, and it has advantages such as improving bone grafting efficiency.

The utility model discloses a lamp convenient to install, which is suitable for being installed on a substrate provided with an installation hole and comprises a lamp body, and an abutting flange extending outwards is arranged at the bottom of the lamp body. The at least two elastic clamps can rotate relative to the lamp body, the elastic clamps move between a first position and a second position, in the first position, the elastic clamps are opened upwards and suitable for penetrating through the mounting holes, and in the second position, the elastic clamps press and abut against the upper surface of the base plate downwards under the action of elastic force, and the abutting flanges abut against the lower surface of the base plate upwards; the sliding piece is in sliding fit with the lamp body in the vertical direction and moves between a third position located on the upper side and a fourth position located on the lower side. At the third position, the sliding piece upwards abuts against the elastic clamp located at the first position and receives force applied by the elastic clamp so that the sliding piece can be kept at the third position through friction fit between the sliding piece and the lamp body; in the fourth position, the elastic clip is allowed to be located in the second position. The lamp can solve the problem that hands are clamped when the lamp is installed.
