Method for improving cold resistance of lawn grass through optical energy variable valence ionic titanium and application thereof

Abstract

The invention discloses an application of optical energy variable valence ionic titanium in improving the cold resistance of lawn grass, and also discloses a method for improving the cold resistance of lawn grass through the optical energy variable valence ionic titanium. The method comprises the steps of 1, preparing optical energy variable valence ionic titanium, to be specific, diluting an ionic titanium mother liquor containing the optical energy variable ionic titanium with purified water to obtain an ionic titanium solution with an ionic titanium concentration of 8-10 mg/L; 2, spraying the optical energy variable valence ionic titanium, to be specific, spraying lawn grass through the ionic titanium solution prepared in the step 1 from a full-blooming period to a fruiting period of the lawn grass, and carrying out ionic titanium spraying treatment every 10 d to complete cold resistance treatment, wherein spraying is not stopped until water drips from leaves every time, and the spraying is carried out three times in total. The appropriate spraying concentration and spraying mode are researched according to the invention, the cold resistance of Eremochloa ophiuroides is improved, the green period of Eremochloa ophiuroides is prolonged, the fact that the state of Eremochloa ophiuroides is prolonged using traditional reagents, such as chemical fertilizers and growth regulatorsin the past is changed, and the healthy and sustainable development of the lawn industry is promoted.

Description

technical field [0001] The invention relates to a new method for improving the cold resistance of turfgrass, in particular to a method for improving the cold resistance of turfgrass and its use. Background technique [0002] Lawn is widely used in urban and rural greening, slope greening, environmental governance, etc. It has become the "skin" of the city and an important part of modern life. With the advancement of the "Beautiful China" construction and the "Land Greening Action" proposed by the "Nineteenth National Congress", the demand for lawns will increase rapidly. However, there are problems such as large water consumption and high maintenance costs in the construction of lawns in our country. Most of the existing lawn greening is at the cost of high energy consumption. [0003] Eremochloa ophiuroides is a warm-season turfgrass that originated in southern my country. It is also known as "Chinese turfgrass". It has the characteristics of less water and fertilizer requ...

Problems solved by technology

[0005] Although the existing methods can enhance the cold resistance and prolong the green period of the grass to a certain extent, the application of chemical fertilizers will cause soil compaction and reduce soil fertility. Therefore, the country has issued the "Action Plan for Zero Growth in Chemical Fertilizer Use", so crops beautify the environment, Ecological lawns should use less chemical fe...
