Problems solved by technology

For example, due to urban development needs, Ruian City in Wenzhou had to occupy part of the farmland to develop industries, and on the other hand, to alleviate land resources, reclamation and land reclamation were carried out, and the land was converted into paddy fields. The problem of high salinity, the land created by reclamation cannot meet the conditions for ordinary rice cultivation

Embodiment 1

[0034] Use a chain mower or harvester to cut off the weeds on the site, so that the sun can be used to dry the field, and spray herbicides to remove the roots of the weeds on the site; then use a large tire rotary tiller for rotary tillage Carry out operations to prevent the car from sinking, and turn over heavy stones and construction waste to the ground; build a pump station, lay water supply pipes on the surface, lay underground drainage pipes underground, and set up anti-scouring troughs, and shallow water through the water supply pipes Flood irrigation, fresh water carries the salt in the soil downward, and is discharged through the underground underground pipe system; the spacing and buried depth are designed according to the local salinity and soil conditions, the spacing is 20 meters, the buried depth is 1.5m, and the water is collected through the DN110 suction pipe to the DN200 corrugated set Among the water pipes, the suction pipe is wrapped with SF geotextile import...

Abstract

The invention provides a method for improving a beach plaster land into a rice field and belongs to the technical field of land improvement. The method for improving the beach plaster land into the rice field specifically comprises the following steps: (1) weeding, (2) rotary tillage, (3) salt elimination, (4) field drying, (5) soil conditioning, (6) irrigation, (7) water finishing, and the like.By adopting the method, salt and alkali components in the beach plaster land can be effectively removed, granular structures in soil can be increased, the soil viscosity can be reduced, and the land can be turned into the rice field beneficial to rice growth.

Description

technical field [0001] The invention belongs to the technical field of land improvement, and in particular relates to a method for improving beach bathing clay land into paddy fields. Background technique [0002] The new coastal saline-alkali land is partly formed by land reclamation. The soil used for land reclamation is generally the soil excavated by the project, some are sandy soil, some are clay soil, and there are stones, construction waste and other sundries. Among them, there are problems such as easy to trap cars, difficult to level, stones, and high salt content in the clay land by the sea. At present, there are a large number of clay land and beach bathing land in China, which have the following characteristics: the surface soil is hard, easy to dry, easy to agglomerate, and becomes muddy when exposed to water; the soil below 10 cm is soft, and heavy machinery is easy to sink. [0003] At present, land resources are scarce, and some cities have begun to occupy f...
