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] Example: Overwintering protection method for Zoysia japonica seedlings for delayed sowing in Shenyang area

[0031] (1) Sowing: Sowing Zoysia japonica seeds on August 10, sowing and managing by conventional methods.

[0032] (2) Overwintering protection

[0033] 1) Promote lawn growth in autumn

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

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

[0036] 1.3) Film mulching: After watering, cover the film with a white mulch film with a thickness of 4-6μm to ensure the supply of nutrients and water during the growth period of the seedlings, and raise the temperature of the bed to make the temperature in the film reach 26 -35°C is beneficial to the growth of Zoysia japonica seedlings;

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 japonica during sowing in a delayed sowing period and normal maintenance for overwintering protection of seedlings, in particular to a large area overwintering protection and maintenance method for warm-season lawn grass in northern my country . Background technique [0002] Zoysia japonica (Zoysia japonica) is a warm-season gramineous turfgrass with developed stolons and rhizomes. The suitable growth temperature is 26-32℃. The grass blades have good elasticity and can form a good and extremely elastic lawn. Zoysiagrass is superior to other grass species in terms of physiological resistance and ecological adaptability, especially its tramp resistance. Zoysiagrass has strong toughness, good elasticity, drought tolerance, barren tolerance, disease resistance, and is suitable for planting in a wide area. Its management is relatively extensive and the maintenance co...
