Embodiment 1

[0030] Using citric acid to improve the heat resistance of tall fescue in a controlled environment in the greenhouse, the main steps are as follows:

[0031] 1. Tall fescue lawn establishment

[0032] The seeds of the commercial variety 'Hungou No. 5' were used as materials, and they were sown in plastic pots (15 cm in height, 13 cm in upper diameter and 10 cm in lower diameter) with a 1:1 mixing ratio of substrate and fine sand, and covered with 1 cm thick fine sand after sowing. Sand; water every day to keep it moist, and germination begins in about a week. After germination, each pot is poured with 200ml of Hoagland nutrient solution once a week, and the grass is mowed when the seedling height is about 10cm, and the height of the grass is kept at 4-6cm; the above cultivation process is performed manually. Carried out in a controlled greenhouse, the temperature is controlled at 18-25°C, the humidity is 60-80%, the light is 14h, and the light intensity is 400-600μmol / m 2 .s,...

Embodiment 2

[0038] Applying citric acid to improve the heat resistance of tall fescue in the natural environment of the field, the operation steps are as follows:

[0039] 1. Tall fescue lawn establishment

[0040] A. Sowing:

[0041] Before sowing, plow the ground deeply, apply superphosphate 50kg / mu and carbon ammonia 50kg / mu as base fertilizer, mix river sand or decomposed sawdust at the same time, use mechanical rotary tillage, and use 3% carbofuran 3kg / mu, 75 % Dikesone wettable powder 1.5kg / mu is evenly spread into the soil for disinfection, then the ground is leveled, and a layer of fine sand with a thickness of about 2-4cm is covered on the ground surface, and the pre-emergent herbicide is sprayed at the same time; Seeds are used to sow and plant in spring and autumn; the seeds of the commercial variety 'Liugou No. 5' are used for sowing, 30g per square meter, and about 1cm of sand is covered after sowing.

[0042] B. Lawn management:

[0043]In the early stage of sowing, water...

Abstract

The invention discloses a method for raising cool-season lawn grass heat resistance through a treatment of foliage spray of citric acid, and relates to the technical field of landscaping lawn management. The method includes the steps of: 1, Festuca arundinacea lawn building and planting, which includes the substeps of sowing and lawn management; and 2, foliage spray of a citric acid solution, wherein sodium citrate is prepared into an optimum concentration of 2mmol/L, and for the built Festuca arundinacea lawn, the sodium citrate solution is uniformly sprayed on the Festuca arundinacea lawn 100kg per mu through a foliage spray method at the high temperature initial stage in summer, and the sodium citrate solution is sprayed again after one week. The method for raising the cool-season lawn grass heat resistance through the treatment of foliage spray of the citric acid obviously raises the heat resistance of Festuca arundinacea by applying the citric acid to the Festuca arundinacea lawn, raises the lawn quality, prolongs the green period, and reduces the yellowing rate. In comparison with the method of seed selection of heat-resistant Festuca arundinacea, the method of the invention has the advantages of short period, fast effect, strong operationality, and low cost.

Description

technical field [0001] The invention relates to the technical field of landscaping and lawn management, in particular to a method for improving the heat resistance of cool-season lawn grass by spraying citric acid on leaves. Background technique [0002] Tall fescue, also known as reed-like fescue and reed-like foxgrass, belongs to the perennial herb of the genus Fescue in the Poaceae family. It is an important commonly used cool-season turfgrass and forage grass. It is distributed in temperate and transitional zones and is widely used. It can be used in various lawns such as pastures, parks, golf courses, sports fields, landscaping and soil and water conservation. Tall fescue can not only absorb a large amount of CO 2 , releasing more O 2 , Fresh and purify the air, but also reduce dust, reduce noise, absorb harmful gases, locally adjust atmospheric temperature and humidity, absorb strong sunlight damage to the eyes. Therefore, it plays a very important role in urban env...
