Open hole fertilization is to dig an open hole in the middle of the two vegetables, the hole is inside the irrigation ditch, open the gap to the inside of the ditch, the gap is lower than the ditch irrigation level but higher than the bottom of the ditch, so that part of the irrigation can flow into the hole to dissolve And diffusing fertilizer; after covering the mulch, the mulch is torn out of a hole above the hole; 1 to 2 days before each irrigation, the fertilizer is applied into the hole; once acupoint, the whole vegetable is used during the growth period. Open hole fertilization reduces the process of digging and covering soil each time compared with conventional point fertilization; it overcomes the shortcomings of low fertilizer fertilization intensity and fertilizer utilization rate. Under the easier farming operation, concentrated fertilization was realized and the fertilizer efficiency was improved.
