Problems solved by technology

[0003] However, although Suaeda salsa is a halophyte, if the total salt content of the 0-20cm soil is greater than 0.6%, the seed germination and emergence rate will be greatly reduced. When the total salt content of the 0-20cm soil is 0.9%, the seed germination and The emergence rate is about 5%, and when the total salt content of 0-20cm soil reaches 1.5%, the seed germination and emergence rate are almost 0
In the prior art, most of the planting of Suaeda salsa in saline land does not consider the problem of soil salinity, and all use fresh water irrigation to press salt at the seedling stage. This method has no problem in low-to-medium saline soil, but the salinity is too high, especially in muddy saline-alkali land. Poor resistance, poor fresh water pressure salt effect, unable to guarantee germination rate
[0004] Moreover, the method of planting Suaeda salsa with fresh water irrigation and salt pressure has improved the emergence rate of Suaeda salsa to a certain extent, but the quality of the planted Suaeda salsa cannot be guaranteed.

Embodiment 1

[0071] The method of planting Suaeda salsa in the silty saline-alkali land of Tianxu Ecological Agricultural Park in Caofeidian:

[0072] (1) On March 5, 2020, 5 m was applied to the area to be planted in the silty saline-alkali land greenhouse of Caofeidian Tianxu Ecological Agriculture Park (0.5 mu, 0-20cm soil with a total salt content of 0.55%). 3 The decomposed cow dung and 10kg NPK compound fertilizer (15-15-15) were ploughed (depth of 30cm) to make a furrow; the improved planting plot was obtained;

[0073] Among them, the width of the furrow is 1.2m, the spacing between the furrows is 30cm, and the depth of the furrow is 20cm;

[0074] (2) according to the consumption of 1kg / mu, Suaeda salina seeds are sown on the gained planting plot in the form of drilling, and the thickness of covering after sowing is 1~2cm vermiculite;

[0075] Among them, the row spacing of drilling is 20cm, and the ditching depth is 3cm;

[0076] (3) Arrangement of irrigation facilities: drip i...

Abstract

The invention belongs to the technical field of suaeda salsa planting, and particularly relates to a method for planting suaeda salsa in coastal muddy saline-alkali soil. The method for planting the suaeda salsa in the coastal muddy saline-alkali soil is provided and comprises soil improvement and irrigation management after sowing. According to the method, soil improvement is conducted on a planting plot through decomposed organic fertilizer and / or agricultural straw, different irrigation management is adopted for different periods, the suaeda salsa can be planted in medium-low-degree salinesoil and can also be planted in muddy severe saline-alkali soil, and the survival rate is higher; and besides, the planting method provided by the invention not only reduces the consumption of fresh water, but also realizes direct utilization of shallow underground saline water, and improves the quality of the suaeda salsa.

Description

technical field [0001] The invention belongs to the technical field of Suaeda salsa planting, and in particular relates to a method for planting Suaeda salsa in a coastal silty saline-alkali land facility and an application in improving the quality and increasing production of Suaeda salsa. Background technique [0002] The growth of Suaeda salsa L., as a pioneer plant of vegetation succession in coastal heavily saline-alkali land, plays a very important role in the reduction of soil salinity. The salt absorbed and taken away by Suaeda salsa accounted for about 10% of the total desalination. By improving the soil structure, accelerating water infiltration, and promoting salt leaching, the desalination accounted for 90% of the total desalination. At the same time, Suaeda salsa seedlings are rich in protein, amino acids, Vc, calcium, magnesium, zinc and other trace elements, and can be eaten as pollution-free vegetables. [0003] However, although Suaeda salsa is a halophyte,...
