Embodiment 1

[0021] 1. Implementation location

[0022] The implementation site is located in Jinhai Farm, Dafeng City, Jiangsu Province (33°04′~34°11′N, 120°52′~120°53′E), with an average annual temperature of 14.7°C, an average temperature of 0.8°C in January, and an average temperature of 0.8°C in July. The temperature is 26.8°C, the annual precipitation is 900mm-1060mm, the frost-free period is 230 days, and the annual sunshine hours are 2241-2496 hours. Seaside mallow has been planted in this area for 7 years.

[0023] 2. Implementation method and results

[0024] (1) Sample collection and measurement: 60 1m×1m quadrats were set up in the improved area, common farmland 2.9km away from the improved area, and unimproved saline soil 0.3km away from the improved area according to the “zigzag” shape, and the samples within the quadrats were collected. For all plants and whole plants, 1kg of 0-20cm soil was collected after removing the topsoil in each quadrat, and finally all the plant sa...

Embodiment 3

[0040] 1. Implementation location

[0041] The implementation site is located in Qingkou Salt Field, Lianyungang City, Jiangsu Province (34°45′~34°47′N, 119°11′~118°04′E), which belongs to the northern subtropical deciduous and evergreen broad-leaved forest climate. This area is an abandoned sun-drying site, the salt content before improvement is as high as 15.6g / kg, the soil is clay loam, and the natural vegetation is little or poorly grown. Been growing seaside mallow for two years.

[0042] 2. Implementation method and results

[0043] (1) Sample collection and measurement: Set up 75 1m×1m quadrats in a zigzag pattern on the improved area, common farmland 4.1km away from the improved area, and unimproved saline soil 0.1km away from the improved area, and collect samples within the For all plants and whole plants, 1kg of 0-20cm soil was collected after removing the topsoil in each quadrat, and finally all the plant samples and soil samples were brought back to the laborato...

Abstract

The invention belongs to the technical field of coastal solonchak improvement and in particular relates to an effect evaluation method for improving coastal solonchak by taking coastal mallows as pioneer species. According to the method, rapidly available phosphorus, alkali-hydrolyzale nitrogen, organic matters, the salt content, total glomalin relevant soil proteins, the soil aggregate content, plant biomass (dry measure) and the like are used as evaluation indexes, and an equation for calculating the indexes for improving the coastal solonchak by taking the coastal mallows is constructed; meanwhile, an evaluation standard is provided; therefore, the effect for improving the coastal solonchak by taking the coastal mallows can be quickly and accurately evaluated. A technical support for improving the coastal solonchak by populating and planting the coastal mallows in coastal areas in China can be supplied, and popularization and application of coastal mallow salt-tolerance oil plants in the coastal areas in China are promoted.

Description

technical field [0001] The invention belongs to the technical field of seashore saline soil improvement, and in particular relates to an effect evaluation method for seashore saline soil improvement with seashore mallow as a pioneer species. Background technique [0002] At present, the relatively mature seaside saline soil improvement technologies mainly include freshwater desalination, underground pipe salt drainage, and foreign soil planting, etc. These technologies require a lot of manpower and material resources, easily cause environmental pollution and damage, and have low long-term comprehensive benefits. It is an ecologically friendly improvement measure to achieve desalination and fertilization of coastal saline soil by planting halophytes. The seaside mallow introduced from the United States by Professor Admiration of Nanjing University from 1993 to 1995 belongs to this type of plant. Seashore mallow (Kosteletzkya virginica (L)) is a perennial herbaceous plant of ...
