This invention belongs to the field of agricultural planting technology and proposes a method for integrated drip irrigation and fertigation of corn using mulch-side planting. The method includes: employing a wide-narrow row planting method; laying mulch film above the narrow rows; pressing the edges of the mulch film into the soil and covering them with soil; sowing corn seeds 4-5 cm outside the edge of the mulch film exposed on the ground; and laying drip irrigation tape under the mulch film. Irrigation is controlled by monitoring the soil matrix potential at a depth of 20-25 cm below the drippers of the drip irrigation tape, initiating irrigation when the soil matrix potential is ≤-15 kPa. During irrigation, all phosphate fertilizer is applied as base fertilizer; a portion of nitrogen fertilizer is applied as base fertilizer, with the remainder applied in multiple top dressings; and all potassium fertilizer is applied as base fertilizer, or a portion is applied as base fertilizer, with the remainder applied in multiple top dressings. This method significantly improves the mulch film recycling rate while ensuring stable and high corn yields, achieving the goals of water conservation, emission reduction, and efficiency improvement in arid areas.

The utility model provides a portable corn fertilizing device of soil fertilization can enter, belongs to fertilizing equipment technical field. Including storage tank, feed pipe, support mechanism, storage tube, base, pit digging mechanism, discharge mechanism, the storage tank's blanking mouth is connected with feed pipe, the support mechanism's one end intercommunication with feed pipe, other end intercommunication with storage tube, to make the fertilizer in storage tank via feed pipe, support mechanism enters storage tube waits for fertilizing, base pit digging mechanism all are connected with the outer wall of storage tube, and base with pit digging mechanism is opposite setting, discharge mechanism is connected with the discharge port of storage tube lateral wall, and the discharge mechanism's fertilizing mouth sets up between base and pit digging mechanism, to make the fertilizer fall into the pit that pit digging mechanism dug. Through the direct contact of soil fertilization reduction fertilizer and atmosphere, effectively prevented the volatilization of fertilizer, improved the utilization of fertilizer.

The application discloses application of compound C-08 in improving ulcerative colitis and intestinal barrier function, and belongs to the technical field of medicines.The application screens the compound C-08, and verifies the improvement effect of the compound C-08 on ulcerative colitis, including the effect of improving ulcerative colitis and repairing intestinal barrier function; the compound C-08 can significantly inhibit the weight loss of a DSS-induced mouse, obviously down-regulate the expression of a colon proinflammatory factor IL1-beta, restore the colon length and reduce a disease activity index, and has the effect of improving ulcerative colitis, thereby providing a new target for the treatment of ulcerative colitis; the compound C-08 can promote the mRNA expression amount of intestinal tight junction to increase and tend to be normal, and has the effect of improving intestinal barrier dysfunction.
