Abstract

The present invention aims to grow crops and make green on saline-alkali land by adding 0.01-2.0% of sorbitol, mannitol, and their composition into coating agent, steep or spraying liquid. The invention is used to improve the growing environment of non-halophytes, especially crops and ornamental plants, so as that the seeds in soil whose salt content is below 0.6% can grow and develop.

Description

technical field [0001] The invention of this product belongs to the field of agricultural technology. Background technique [0002] Due to the influence of man-made and natural factors, the degeneration of the original cultivated land into saline-alkali land is showing an increasing trend. In addition, there are a large number of salt flats in seashores and deserts. The need for human development of saline-alkali land is more urgent than ever. However, the growth and development of many non-halophytic plants have been greatly affected by the soil with a salt content above 0.4%, making it difficult to plant. Improving plant varieties and improving the habitat of saline-alkali plants are the two main means by which most saline-alkali lands can be utilized. Among them, by adding plant hormones such as gibberellin and related mineral elements such as potassium ions, crops such as cotton can grow normally in soil with a salt content of 0.4%, and huge economic benefits have been ...
