Problems solved by technology

There are also those who continue to sow. Through conventional overwintering management, it is found that the young Zoysia lawn is almost difficult to overwinter, that is, it cannot turn green and survive in the second spring, and the survival rate is extremely low.

Embodiment

[0030] Embodiment is aimed at the overwintering protection method of Zoysia seedlings with delayed sowing in Shenyang area

[0031] (1) Sowing: Zoysia seeds were sown on August 10, and conventional methods were used for sowing and management.

[0032] (2) Overwintering protection

[0033] 1) Promote lawn growth in autumn

[0034] 1.1) Fertilization: When the minimum temperature drops to 14-16°C, start to apply urea and potassium dihydrogen phosphate mixed fertilizer. Fertilization amount: urea 8-10g / m 2 , Potassium dihydrogen phosphate 4-6g / m 2 ;

[0035] 1.2) Watering: Water immediately after fertilization to keep 25-30cm of the surface of the lawn bed moist;

[0036] 1.3) Mulching: Mulching is performed after watering, and covered with a white mulch film with a thickness of 4-6 μm, so as to ensure the supply of nutrients and water required for the seedling growth period, and increase the temperature of the lawn bed, so that the temperature inside the film reaches 26 -3...

Abstract

The invention provides a zoysia japonica seedling overwintering protection method for delayed sowing in the northern area. By the application of the technologies of water and fertilizer processing, mulching film temperature increasing for prolonging of the growing period, rolling in the period of dormancy, soil covering for protection, scientific soil covering ratio, rolling and soil supplement during thawing in the early spring, watering and scarification in the period of seedling establishment, and the like, the growing period of a primary lawn sowed in a delayed mode is prolonged, all growth indexes reach the standard required before a normal lawn overwinters after seedlings grow for another 20-25 days serving as the prolonged growing period, and the seedlings can overwinter successfully due to protection of overwintering protection measures. The zoysia japonica seedling overwintering protection method solves the problem that due to delaying of the construction progress, the time of completion of the whole landscape engineering is affected, and also achieves the technical aim that warm-season lawns overwinter successfully.

Description

technical field [0001] The invention relates to a method for overwintering protection of warm-season turfgrass Zoysia spp. delaying the sowing period, and normal maintenance for overwintering seedlings, and particularly relates to a large-scale overwintering protection and maintenance method for warm-season turf young lawns in northern my country . Background technique [0002] Zoysia japonica is a warm-season grass turfgrass with well-developed stolons and rhizomes, and its suitable growth temperature is 26-32℃. The blades of this grass have good elasticity and can form a good, very elastic lawn. Zoysia is superior to other grass species in terms of physiological resistance and ecological adaptability, especially trampling resistance. Zoysia has strong toughness, good elasticity, drought resistance, barren resistance, disease and insect pest resistance, and is suitable for planting in a wide range of areas. Its management is relatively extensive, and its maintenance cost ...
