6results about How to "Good holding effect" patented technology

The invention belongs to the technical field of biological fertilizers, and particularly provides a carbon sequestration and nitrogen conservation biological organic fertilizer and a preparation method thereof.Molybdenum, copper, cobalt and composite flora are loaded on biomass charcoal to prepare load type biomass charcoal; and jointly preparing the supported biomass charcoal, the perilla biomass extracting solution and animal waste into the biological organic fertilizer. According to the biological organic fertilizer provided by the invention, unnecessary waste of strain resources can be avoided, and the organic fertilizer can remarkably promote the immobilization effect of soil on ammonium nitrogen and nitrate nitrogen; the compound bacteria liquid promotes decomposition of organic matters and effectiveness of nutrients, and promotes improvement of soil, so that improvement of soil productivity is facilitated; meanwhile, the organic fertilizer can obviously improve the enzyme activity of the soil and promote the improvement of the fertility of the soil, so that the effect of conditioning the soil is finally realized.

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.

The utility model discloses an assembly type building steel beam vertical plate stable hold-down device which comprises a first combined frame, a second combined frame and four vertical rods, the number of the vertical rods is four, the four vertical rods are clamped and installed on the top of the first combined frame and the top of the second combined frame respectively, and the first combined frame and the second combined frame each comprise an adjusting inner rod; according to the stable pressing device, a connecting inserting groove in one end of a threaded rod is connected to the outer side of a connecting inserting block at one end of a rotating rod in a sleeving mode, an inserting column is inserted into a circular hole, then the threaded rod is rotated, so that a second combined frame is close to a first combined frame, a vertical plate is pressed through an attaching plate, and the vertical plate is kept vertical and stable; the situation that the vertical plate inclines and deviates due to the small contact area of the vertical plate and the transverse plate is prevented, it is guaranteed that the pressing tightness of the connecting position can be guaranteed when the vertical plate is welded, in addition, the device is suitable for vertical plates of different widths, and the using effect of the device is improved.
