Abstract

The invention provides a method for cultivating forage rape in the saline-alkali land and belongs to the technical field of saline-alkali land utilization and exploitation. The method comprises stepsthat 1), after the saline-alkali land is ploughed deeply, the land is leveled; 2), forage rape seeds are sown on the flat land of step 1), the seedling water is watered, and the forage rape includes saline-alkaline-tolerant and drought-tolerant forage rape varieties; and 3), after the rape seeds are emerged, field management is carried out, and the rape is harvested in the flowering period. The method is advantaged in that the rape emergence rate is 1.49-2.13 times that of the conventional scheme, and the rape yield is 1.63-2.54 times that of the conventional scheme.

Description

technical field [0001] The invention belongs to the technical field of development and utilization of saline-alkali land, and in particular relates to a method for cultivating forage rapeseed in saline-alkali land. Background technique [0002] Soil salinization is a worldwide problem. There are 99.13 million hectares of saline-alkali soil in my country, which is about 1.47 billion mu. More than 100 cities in the country are located in the saline-alkali distribution area. Nearly 500 million mu of farmland has been lost or abandoned due to salinization, mainly concentrated in the arid and semi-arid regions of North China, Northwest China and Northeast China. In addition, during the cultivation process, the long-term excessive application of chemical fertilizers leads to the intensification of secondary salinization of the soil, serious compaction, and the continuous expansion of salinized and alkalized soil. [0003] The area of ​​salinized land in the Hu, Bao and E regions ...
