Seeds have been germinated, sprouted quickly and are of good quality. Due to the increase of seedling rate, the seed sowing amount can be appropriately reduced by 20-25%. At the same time, due to the shortening of the seedling period, the water spray at the seedling stage was reduced.
First, the germination operation points
1. Dry seeds are soaked in water for 1 to 2 hours. Cold-season grasses can be treated with cold water or slightly warmer water.
2. Remove the seed and remove it from the river sand with clean and no debris. According to the seeding rate of 20 times, stir evenly and mix several times repeatedly. After hand-holding, no dripping between the fingers is appropriate (River sand The proportion can be more or less, and some more favorable spread.)
3. Normal sowing period, the general method of germination at room temperature, the sand mixed seeds, stacked on a common floor or covered with plastic film, insulation moisture, but also can promote its early sprouting.
4. When the temperature is low, high-temperature germination methods are adopted. Usually, sand-inoculated seeds are planted in a snake skin bag, wooden box, etc., in accordance with the sown area of ​​100 square meters, and transferred to a greenhouse and a greenhouse for germination. Temperature and storage time vary according to species of grass. The cool season grasses must be controlled at about 28°C, and they are generally stacked for 2 to 3 days.
5. During the germination period, changes in the buds should be checked twice a day. If some of the seeds are found to be "white", they must be quickly sowed. Generally, the cool-season grass species are stacked for a maximum of 3 days. Whether or not “whitening†or not, they should be quickly sowed to prevent seed mildew.
Second, sowing
1. The soaked and soaked seeds must be sowed on the moist and moist seedlings and germinate soon after exposure to dew and sunlight. If the germinating wet seeds are sown in a dry place, the germination rate will be reduced due to the sun-dried wind, so the sowing season is better.
2. After deep-leveling and seedlings, the deep soil layer and the wet soil layer must be more than 20 cm in the first half or the first day of the next seedling type. In this way, the wet seed can be seeded several days after sowing. The seedlings are wet due to the soil, and no water spray is required after sowing.
Third, after germination, wet seeding method
1. It is very difficult to sow, sow, and cover soil after extensive sowing. The seedling area is generally divided into 1,000 square meters as a sowing unit, and when it is sowed, it is divided into l00 square meters to avoid missing broadcast and repetition.
2. The grass is small and can be used to gently “sweep†the wet soil with a fine-toothed rake before sowing the seed. After the seeds are scattered, the seed is then pulled down with a fine-toothed hoe to make it fall into the soil, or a bamboo broom is used. Repressing the soil layer can also sow the seed that is scattered on the surface into the soil and between the grain and the grain, so that the soil particles and seeds are closely combined. After many inspections, using the method of “pulling down†and “fighting down†using pull or bamboo rafts, most of the seeds can fall into the soil and play a role in covering.
There are two kinds of lawn seed germination methods: First, high-temperature germination, the use of low temperatures, can increase the sowing period of 10 to 15 days. The second is normal temperature germination. Adoption within the normal sowing period can also improve the quality of seedlings and reduce the artificial management of seedlings.
