Cool-season lawn: sowing in August~November of the lunar calendar, sowing in January~March, germination temperature should not be high, preferring cool climate environment, excellent cold tolerance.

Warm-season lawn: 4~August lunar calendar sowing, like high temperature, germination temperature requirements, cold season should not be sown, the temperature is lower than 16 degrees, the germination rate is very poor.

When choosing lawn seed, you must choose varieties suitable for the region's climatic environment, can not be blind, or plant something bad.

A, land preparation

Because of a variety of factors impede, such as sowing time is not fixed, site environment can not be, meteorological reasons, see the effect of the time and other factors, most people sowing lawn, can not fully comply with the refined seeding guidelines, so we wrote a really work, take care of the germination rate and optimize the sowing step by step. So we wrote a method that does work, takes care of germination rates and optimizes the seeding process. First, the field in accordance with the planning requirements, leveling the terrain, and the arrangement of good drainage, slope substrate facilities; secondly, the ground is plowed and harrowed to break up, to maintain a slope conducive to drainage and watering, or digging drains.

Two, sowing specification

Favorable weather for sowing, but not every day, lawn seed is extremely small, each kilogram of seed has a large tens of thousands to hundreds of thousands of up to, the size of the imaginable. There is a little breeze, can make the seed that should be sown evenly, caused by the accumulation, resulting in part of the location of the seedling too much, and individual locations did not grow out of the seedling of the situation caused by the spot into a spot of convex spots and waves of sparse spacing, greatly affecting the green effect and acceptance of the time of inspection.

There is a breeze in the environment, sowing lawn, should be mixed with the seed and soil, and all mix well, during the period of coarse sand mixed with the seed together, it will be evenly spread on the ground, if the fine sand is dry, please spray the fine sand to get wet in the mix in the seed. At the end of the sowing, you can use a tractor to crush a little to ensure that the seed and soil completely combined.

It is not necessary to spray the seeds if they are sown before it rains, as a light rain is enough to wake up the seeds and allow them to germinate, or to spray them after sowing.

Three, sprouting maintenance

The lawn seed germination suitable temperature is 15 ~ 27 degrees, 7 ~ 12 days after sowing seedlings, 15 ~ 22 days all lawn seed germination end. In the germination time, when to maintain adequate soil water requirements, to ensure the normal growth of seedlings and neatness.

In the seedling height grows to 9~12cm or grows out of the seedling after 40~55 days, applies the grass grinder without omission to press once, presses the grass can make the lawn quickly into the texture of the lawn, can accelerate the root extension, accelerate the lawn creeping planting.
