When the reporter interviewed Gucheng Street in Shouguang City, the vegetable farmer Zhang Shifu told the reporter: "His pepper has been planted for nearly two months, and the compound fertilizer has been applied a lot, but it is not open, the pepper is weak and the yield is low." The reporter found in the greenhouse of Master Zhang that the soil in the greenhouse was sticky soil and the permeability was poor. Master Zhang used rice husks according to the amount of 8 square meters per mu before the pepper was planted. The amount of organic fertilizer used was small, and the effect on soil improvement was not Obviously, the soil is still severely corroded, which affects the permeability of the soil, which is not conducive to the growth of the roots of the peppers, resulting in less root coefficient of the peppers, reducing the ability of the roots to absorb nutrients, resulting in weak pepper growth. Under this circumstance, it is recommended that Master Zhang can promote the growth of pepper roots by watering after each watering, and pay more attention to the use of 963 roots and other roots to promote the growth of pepper roots. . At the same time, reduce the use of compound fertilizer, change the water-soluble fertilizer, improve the utilization rate of fertilizer, reduce the soil compaction caused by excessive use of chemical fertilizer, and prevent the salinization of soil, thereby promoting the growth of pepper.
