Try the basic situation

The demonstration site is located in Dongfangfang Village, Qiwusutu Township, Chayou Middle School, where the potato Xisen No. 6 variety is planted. The total planting area is 1,400 mu, and the demonstration area is 300 mu. The planter is Meng Shouzhong, and the planting time is May 15, 2021.

Fertilizer Application

Except for the adjustment of the types of base fertilizer and topdressing fertilizer, other agricultural operations remained the same.

Growth analysis

Before the production test, the comparative section analysis of the root system was carried out. The potato root system using Yuantaifeng active organic fertilizer grew vigorously, and the root system spread to a range of more than 25cm around. The potato root system in the control field did not reveal the vigorous root growth area until the potatoes were dug out, and the roots were distributed around the 15-20cm of the potato formation area, indicating that Yuantaifeng active organic fertilizer can stimulate the growth of the plant root system, and the root hairs are densely distributed, which is conducive to absorbing the soil Nutrients in the fertilizer can improve the utilization rate of fertilizer.

Comparison of Yuantaifeng organic fertilizer and traditional fertilization

On September 24, the yield was measured in the Mengshouzhong potato demonstration field and the yield analysis was carried out with the control field. In the demonstration field and the control field, the random sampling length was 1m, the row spacing was 0.9m, and the sampling area was 0.9㎡. The actual measurement results are as follows: Demonstration field: a total of 4 plants, 30 tubers, and a total weight of 5.58. :15.

Economic Benefit Analysis

From the product harvest comparison photos, it can be seen intuitively that the potatoes using Yuantaifeng active organic fertilizer are more uniform in growth than the control field, and the potato shape is regular. The yield of the demonstration field through yield measurement is 4133.54kg/mu, and the output of the control field is 3955.75kg/mu Mu, the potato using Yuantaifeng active organic fertilizer increased by 177.79kg/mu compared with the control field, an increase of 4.49%. Based on the current purchase price of 1.2 yuan/kg, the income per mu increased by 213.348 yuan.
