Method suitable for winter sowing of zoysia japonica in northern area

Abstract

The invention relates to a method suitable for winter sowing of zoysia japonica in a northern area. The method comprises the following steps: preparing a site before turf establishment, namely turning up soil in the ninth and tenth months, drying the soil in sequence, rotating the soil, shaping, removing sundries, laying sand and turfy soil, rotating the soil, leveling by dragging, watering and finely performing soil preparation; establishing turf, namely performing turf establishment when the highest temperature is about 10 DEG C and the lowest temperature is about 0 DEG C for 3 consecutive days, ditching in a direction parallel to a contour line by a ditching machine, performing broadcast sowing on zoysia japonica seeds with the germination rate of 80%-85%, dragging floating soil brought to the banks of a ditch back to the ditch for covering seeds, and finally covering by sand; performing seed germination and seedling period management, namely pressing by a roller when the highest air temperature is 15-18 DEG C and the lowest air temperature is 5-8 DEG C for 3-5 consecutive days in the next year, supplying the sand for covering the turfy soil, watering and performing seedling period management. The invention provides a new way for winter sowing of the zoysia japonica, so that the winter sowing of warm-season glass seeds in the northern area becomes reality.

Description

technical field [0001] The invention relates to a technique for sowing zoysia in winter, in particular to a lawn building method suitable for sexual reproduction of warm-season lawns that are sown in winter and germinate in spring in northern regions. 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℃. Its management is relatively extensive, and its maintenance cost is low. It is one of the best grass species for football fields, golf courses, open green spaces and soil fixation and slope protection. [0003] In southern China, the sowing time of zoysia is almost not restricted by climate and season, not only grows well, but also is evergreen all year round; while in northern my country, especially in the northeast, due to the cold and dry winter, the sowing time of zoysia is strictly controlled. Restriction, the sowing time should not be too late, otherwise, t...

Problems solved by technology

In production practice, it often occurs that the construction schedule is delayed due to the failure of the above-mentioned processes to be completed on time, which causes the planting of zoysia to miss the appropriate time for planting and building a lawn, and can only be planted in the spring of the next year.

This has brought many adverse effects to the construction of the project: on the one hand, the repeated transportation costs of building turf tools, grass seeds and other turf building materials have increased (long-distance transport to the construction site, and the seeds that cannot be sown in the same year need to be transported back to the company, and then re-transported to the company when sowing the next year. Construction Site

), the increase in occupancy costs of storage space for building turf materials such as turf seeds in winter, and the increase in the cost of re-soiling and modeling of the turf building site before planting in the next year, resulting in an increase in engineering costs; The construction started in the spring of the next year, and the delayed project started at the same time as other projects undertaken by the company in the spring of the next year, resulting in insufficient supply of the company's engineering management personnel, technical personnel, construction workers, logistics support, etc., which brought many difficulties to the company's management

In production practice, the above two aspects have seriously affected the engineering company in terms of construction cost, construction progress and quality.
