Background
Most soil textures of orchard soil in south China are sticky, clay has the characteristics of high water content, low density, poor compressibility and the like, and the surface tension of the clay is large, so that water can be kept absorbed in soil pores to form bound water, a soil aggregate structure is damaged, the root system extension of fruit trees is influenced, the fruit trees cannot absorb water and nutrients in time, and the current situations of weak growth vigor, low yield and poor quality of the fruit trees are formed.
With the rapid development of agriculture, people apply chemical fertilizers in the fruit tree planting process for a long time without paying attention to the supplement of organic fertilizers in pursuit of high yield and high yield, so that soil organic matters are lacked, soil hardening is serious, diseases and insect pests in soil are easy to occur, the fruit tree yield is not improved, and the fruit trees cannot grow normally. Therefore, the method has important significance for repairing soil health and promoting the growth of the root system of the fruit tree while improving the soil aggregate structure.
Much research is currently devoted to improving soil properties and restoring soil aggregate structures. Patent publication 102617241A, a Water-retaining soil-loosening nitrogenous fertilizer, discloses a nitrogenous fertilizer capable of improving soil structure. A water-retaining soil-loosening nitrogen fertilizer is characterized by consisting of a nitrogen fertilizer, lauryl alcohol ethoxy ammonium sulfate and a water-retaining agent. The invention has the main advantages that lauryl alcohol ethoxy ammonium sulfate and the water-retaining agent are added, so that the water-retaining agent has the functions of retaining water and loosening soil. However, if only ammonium laureth sulfate is used as a soil loosening agent, the soil structure-improving effect is poor.
The applicant of the invention, the Chengdu Chaoyang crop science corporation, starts to concentrate on the development and research of the soil granular structure repairing agent in the 90 th century of 20 th century, develops and forms a 'deep ploughing free' soil conditioner (with the patent number being ZL00120300.1), and obtains the first soil conditioning registration certificate in China in 2002; the technical research on the soil aggregate structure modifier is dedicated for more than ten years, and the soil aggregate structure repairing effect is continuously improved.
