Newly reclaimed farmland soil rapid fertility betterment improving method

Abstract

The invention discloses a newly reclaimed farmland soil rapid fertility betterment improving method, and relates to the soil improvement technical field; in a newly reclaimed farmland, continuous deep ploughing land, organic and inorganic combined application, straw turnover, soil curing agent application and water-retaining agent application are realized, thus improving newly reclaimed farmland soil physical and chemical properties, fast improving soil fertility, and recovering farmland productivity; the novel method can solve the problems that a newly reclaimed farmland is poor in soil fertility, low in organic matter content, poor in soil composition, and low in crop output and moisture utilization efficiency; the novel method can fast fertilize the soil, can obviously improve soil organic matter and nitrogen phosphor potassium nutrient contents, can improve soil physical property, can improve soil microbe activity, can fast fertilize soil, and can obviously improve crop output and moisture utilization efficiency; the novel method is fast in effectiveness, easy to promote, and can provide substantial effects for newly reclaimed farmland soil rapid fertility betterment.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a method for rapid fertilization and improvement of newly cultivated farmland soil. Background technique [0002] The dry farmland in the hilly and gully area of ​​the Loess Plateau is located in the loess area and the mountainous area where water and soil erosion is serious. Most of the cultivated land is sloping farmland. The main characteristics of the farmland in this area are running away from water, soil, and fertilizer, and the ecological environment is fragile. It is a strategic measure to maintain water and soil and improve land productivity. In recent years, in order to prevent and control the serious problem of soil erosion in agricultural production, various places have vigorously promoted the construction of new terraced fields. In Gansu Province alone, the annual new terraced fields have reached about 1.5 million mu. Now large-scale bulldozers are used to c...
