Method for improving the cold resistance of turfgrass and its application using titanium ion with variable valence of light energy

Abstract

The invention discloses the use of titanium with variable valence of light energy in improving the cold resistance of turfgrass, and discloses a method for improving the cold resistance of titanium with variable valence of light energy at the same time, comprising the following steps: Step 1, Preparation: Dilute the ionic titanium mother liquor containing light-energy variable-valent ion titanium with pure water to an ion-titanium solution with a concentration of ionic titanium of 8-10 mg / L; step 2, spraying of light-energy variable-valent ion titanium: adopt step 1 The prepared ionic titanium solution is sprayed for the first time on the turfgrass from the blooming stage to the fruiting stage, and the ionic titanium spraying treatment is carried out every 10 days. Apply three times to complete the cold resistance treatment. The present invention develops suitable spraying concentration and spraying method, improves the cold resistance of Wuling sage grass, promotes the prolongation of its green period, changes the state of using traditional reagents such as chemical fertilizers and growth regulators to prolong the state of sage grass, and promotes The turf industry is developing healthily and sustainably.

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 fertilizers; the application of growth regulators will affect the normal growth of plants, and there is also a risk of environmental pollution

Therefore, as the country controls the application of chemical fertilizers and the impact of growth regulators on the normal growth of plants, the use of chemical fertilizers and growth regulators to prolong the green period of false grasses has very large limitations.
