Problems solved by technology

At the same time, the above-mentioned methods all have certain shortcomings, such as a long period of reasonable fertilization and drought-resistant training, and the process of cultivating drought-resistant varieties is relatively complicated, requiring a lot of manpower and financial resources, while the drought-resistant effect of spraying a single plant growth regulator is general and different types and different species. Concentrations of growth regulators have large differences in improving drought resistance

Embodiment 1

[0032] Present embodiment is the method for improving seashore paspalum drought resistance, specifically comprises the following steps:

[0033] (1) Fertilization for soil preparation: 2 weeks before the paspalum lawn is planted, use herbicides (Syngenta Group) to remove impurities chemically, and 4 days later, manually remove impurities and plow the lawn bed to clean up the bricks, Stones, tree roots and other debris, rake the soil, and use 3% ferrous sulfate (Tianjin Bodi Chemical Co., Ltd.) to disinfect the soil at an amount of 0.5 kg per square meter, and apply enough base fertilizer. Including organic fertilizer (Leili organic fertilizer, dosage 250g / m 2 ) and low-nitrogen high-phosphorus-potassium compound fertilizer (Scotts compound fertilizer, 9-14-19, dosage 120g / m 2 ).

[0034] (2) Apply water-retaining agent: After the land is prepared, apply acrylamide-acrylate copolymerized cross-linked water-retaining agent (positive energy produced by Linyi Wohua Bioengineerin...

Embodiment 2

[0044] The difference between this example and Example 1 is that the composition of the mixed liquor sprayed on the seaside paspalum foliage is different, and the mixed liquor in this example includes 0.02mg / L of 2,4-epibrassinolide, 60mg / L humic acid, 1.5g / L potassium dihydrogen phosphate.

[0045] Simultaneously, in order to verify that embodiment 2 improves the effectiveness of the method for improving the drought resistance of seashore paspalum, the seashore paspalum lawn has been subjected to the following treatment: before the lawn is built and planted, the soil in the upper layer 10cm of the pot is treated with 30g / m 2 The amount of water-retaining agent was applied and the mixed solution was sprayed 3 times 5 days before, 3 days before, and 1 day before the drought treatment.

[0046] On the 21st day of drought treatment, the soil water content was tested according to the conventional method, and the result was that the soil volume water content increased by 1.15 time...

Embodiment 3

[0048] The difference between this example and Example 1 is that the composition of the mixed liquor sprayed on the seaside paspalum foliage is different, and the mixed liquor in this example includes 0.04mg / L of 2,4-epibrassinolide, 90mg / L humic acid, 2.5g / L potassium dihydrogen phosphate.

[0049] Simultaneously, in order to verify that embodiment 3 improves the effectiveness of the method for improving the drought resistance of seaside paspalum, the seashore paspalum lawn has been subjected to the following treatment: before the lawn is built and planted, the upper layer 10cm of soil in the pot is treated with 30g / m 2 The amount of water-retaining agent was applied and the mixed solution was sprayed 3 times 5 days before, 3 days before, and 1 day before the drought treatment.

[0050] On the 21st day of drought treatment, the soil moisture content was tested according to the conventional method, and the result was that the volumetric soil moisture content increased by 1.21...

Abstract

The invention relates to the field of lawn grass resistance physiology, in particular to a method for improving drought resistance of seashore paspalum. The method comprises the specific steps that a water-retaining agent is applied in soil of a lawn where seashore paspalum is planted, and mixed liquor is sprayed on the surfaces of seashore paspalum leaves after the seashore paspalum lawn is formed, wherein the mixture liquor per liter comprises, 0.01-0.05 mg of 2,4-epibrassinolide, 50-100 mg of humic acid and 1.0-3.0 g of monopotassium phosphate. The method for improving the drought resistance of the seashore paspalum is easy to implement, can produce effects rapidly, and can improve the drought resistance of the seashore paspalum within a short time. Meanwhile, the using amount of various materials is small, so that no secondary pollution is produced to environment; under drought conditions, after the method is adopted, the volumetric water content of soil can be improved by 1-2 times, and the good lawn viewing value of the seashore paspalum is kept.

Description

technical field [0001] The invention relates to the field of lawn grass resistance physiology, in particular to a method for improving the drought resistance of seaside paspalum. Background technique [0002] my country is a country with extremely scarce water resources per capita, especially in the arid and semi-arid areas in the north. At the same time, in the humid and semi-humid southern regions, periodic, seasonal or temporary droughts will also occur due to the unevenness of precipitation. In recent years, with the rapid development of the economy, the rapid expansion of cities, and the gradual improvement of people's requirements for the quality of life, the urban green area is also increasing year by year. gradually restricted. Water is one of the necessary conditions for the growth of turfgrass. Drought stress will not only affect the quality of turfgrass lawn appearance, but also cause corresponding changes in its morphology, structure and physiological metabolis...
