Method for rapidly increasing organic matter in orchard soil of yellow river beach land

Abstract

The invention discloses a method for rapidly increasing organic matter in orchard soil of a yellow river beach land. The method comprises the following steps: (1) dividing a yellow river beach orchard into a plurality of orchard units by using orchard fences and region division guardrails, and sowing annual leguminous forage grass from late March to early April; (2) after the leguminous forage grass covers the grassland, putting poultry into one orchard unit; regularly transferring the poultry to the next orchard unit, and replacing a new batch of poultry when the poultry grows to a growing period; (3) in a leguminous forage grass mowing period, harvesting forage grass, crushing one part of the harvested forage grass to serve as poultry feed, and gathering the rest of the forage grass to prepare compost; and (4) starting from the middle ten days of September, sequentially turning and pressing the leguminous forage grass of each orchard unit, applying the compost in the turning and pressing process, and sowing annual gramineous forage grass on the turned and pressed land. The method is suitable for increasing the organic matter content of the orchard soil of the yellow river beach, and has the advantages of being good in effect, taking effect rapidly, being low in cost and the like.

Description

technical field [0001] The invention relates to the technical field of soil organic matter improvement. Specifically, it is a method to quickly increase the soil organic matter of orchards in the Yellow River floodplain. Background technique [0002] The Yellow River is famous all over the world for its large amount of sediment transport and high sediment concentration in its currents. The Yellow River beach area is an important area for depositing Yellow River sediment and storing large floods. Due to the diversion of the Yellow River, a large area of ​​the Yellow River beach has been left in the places where the Yellow River swung. The land in the Yellow River beach is barren, and the soil type is mainly sandy soil with loose structure and poor water and fertilizer retention. The loose loess sand in the Yellow River beach becomes an important source of winter dust on both sides of the Yellow River. In order to improve the ecological environment of the Yellow River beach...
