The asparagus is a perennial edible and medicinal vegetable with strong salt and alkali resistance and high economic value, and the planting area and export amount of the asparagus in China are all in the first place in the world. The method has important significance in developing asparagus industry in yellow river delta and coastal saline-alkali soil, protecting ecology and developing high quality in yellow river basin, efficiently developing and utilizing saline-alkali soil, and increasing income of peasants and vibration of villages.
The scholars at home and abroad have preliminary researches on the aspect of cultivating asparagus in saline-alkali soil. Research on screening of salt-tolerant asparagus varieties shows that most varieties can sprout normally under the stress of 0.3% NaCl, some varieties can sprout under the stress of 0.5% NaCl, and salt-tolerant varieties suitable for planting in light saline-alkali lands are screened. Most researches prove that the adaptability of the asparagus seedlings to the saline-alkali can be improved by using the saline-alkali soil with the salt content of 0.3%, the survival rate of the saline-alkali soil planted at 0.3% reaches more than 90%, and the seedlings are quickly recovered and grow vigorously. The existing saline-alkali soil asparagus cultivation mode basically reduces the salt content of soil cultivation layers through engineering and agronomic measures such as ditching bench fields, hidden pipe salt removal, fresh water salt pressing, plastic film mulching and the like.
The patent CN103858646A discloses a coastal saline-alkali soil asparagus cultivation method, which is characterized by comprising the steps of ditching blind pipes for salt removal, field planting ditches for water collection and salt pressing, and plastic film mulching for preventing reverse salt, but the method has higher cost, the field planting ditches are high in humidity and easy to rot roots, and the film mulching is easy to cause white pollution.
