Embodiment 1

[0039] A method for quickly constructing a paddy field soil structure in dry land, said method specifically comprising the following steps:

[0040] S1. Carry out field planning for dry land plot units that need to be transformed into paddy fields, and remove impurities such as plants, stones and plant roots in the soil;

[0041] S2. On the basis of step S1, use engineering machinery to peel off the tillage layer in dry land with a thickness of 15 cm. Move the stripped soil to the vicinity of the plot for centralized storage for subsequent use. Block planning, leveling to a horizontal state by digging high and filling low, and building the field ridge at the same time, the top of the field ridge is 40cm higher than the field surface;

[0042] S3, on the basis of step S2, pour enough water on the leveled field surface, and the soil permeable depth is 10cm;

[0043] S4. On the basis of step S3, use engineering machinery to evenly compact the flat and wet field surface and field...

Abstract

The invention discloses a method for quickly constructing a soil layer structure of a dryland transformation paddy field. The method comprises the following steps that S1, field parcel planning is conducted on a dryland plot unit which needs to be transformed into a paddy field, and impurities such as plants and stones in the soil are removed; S2, stripping and stockpiling are conducted on a farming layer by utilizing an engineering machine, the field surface is leveled, and field ridges are tamped; S3, enough water is poured to the leveled field surface with the farming layer stripped; S4, tamping and compaction are conducted on the leveled and moistened field surface and field ridges by utilizing an engineering machine; S5, a prepared paddy field seepage control agent is sprayed to the field surface and the field ridges by utilizing an engineering machine; S6, organic materials are put; S7, the field surface treated in S6 is backfilled with soil of the farming layer stripped and removed in S2, water is injected, and tillage beating is conducted through land raking; S8, the ph value of the soil of the farming layer is measured, and a soil improver is put. By means of the method, the dryland soil layer structure can be transformed into a paddy field soil layer structure suitable for aquatic farming in a short time, and the soil ecosystem is restored.

Description

technical field [0001] The invention relates to the technical field of cultivated land quality improvement and transformation, in particular to a method for rapidly constructing paddy field soil layer structure for dry land transformation. Background technique [0002] Cultivated land is the most precious land resource on which human beings depend for survival, and it must be well protected and well developed. In recent years, with the development of the economy and society, especially the in-depth promotion of industrialization and urbanization strategies, the occupation of cultivated land by non-agricultural construction projects is both inevitable and prominent, and the balance between occupation and compensation of cultivated land is becoming more and more severe. A series of new policy requirements such as "occupy one to supplement one", "occupy the superior to supplement the superior", "occupy the paddy field and supplement the paddy field" were introduced. At present...
