Embodiment Construction

[0026] The invention is a double-season planting method for oil sunflowers in heavy saline-alkali coastal areas, which provides a stable soil environment for oil sunflower planting by using the transformation method of building terraces and shallow ponds, and ensures the sowing and growth of oil sunflowers through the use of sea ice water irrigation Increased water demand during the period, greatly increased land use efficiency and oil sunflower production, and solved the problems of idle water and soil resources and low land production potential in coastal saline-alkali areas.

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] In specific embodiments, the land improvement method and various raw materials used in the invention are conventional methods and conventional commercially available products (except sea ice water), which can be realized and obtained through conventional calculation and market channels. ...

Abstract

The invention relates to a double-cropping planting method for oil sunflowers in coast heavy saline soil. The double-cropping planting method for the oil sunflowers in the coast heavy saline soil is characterized by comprising the following steps of: A, confirming a heat-suitable area and suitable sowing time for the oil sunflowers; B, building raised field-shallow pond reformed heavy saline soil; C, planting the oil sunflowers in raised fields in spring and summer and performing sea-ice water irrigation; and D, harvesting. The double-cropping planting method for the oil sunflowers in the coast heavy saline soil has the beneficial effects that a stable soil environment is provided to planting of the oil sunflowers by utilizing a reforming method of building raised fields-shallow ponds; water demand for the oil sunflower sowing time and a growth period is guaranteed through the sea-ice water irrigation, and therefore, the land utilization efficiency and the yield of the oil sunflowers are greatly increased, and the problems that land and water resources of the coast heavy saline soil are unused and the land production potential is low are solved.

Description

technical field [0001] The invention relates to the technical field of water resources utilization and coastal saline-alkali land improvement, in particular to a double-season planting method for oil sunflowers in coastal heavy saline-alkali land. Background technique [0002] The coastal area has sufficient heat and rich saline-alkali land resources, but the lack of fresh water resources seriously limits the sustainable development of coastal agriculture. The traditional improvement of saline-alkali land is mainly achieved through irrigation and drainage measures such as fresh water spraying salt, extracting groundwater, and lowering the groundwater table. Along the coast, about 20 million mu of coastal saline-alkali land is difficult to use due to lack of fresh water, and it is difficult for crops to grow. The Bohai Sea is the icy sea area with the lowest latitude in the world. The sea ice formed through the natural low temperature process has a salinity much lower than t...
