At this stage, according to 4-5 of irrigation. In short, grass types, water requirements are different, you mustAccording to the climate conditions and plant species to determine irrigation of the lawn. About a day, when irrigation is better depends on irrigation. In theory, the same period as long as the amount of irrigation water is less than the infiltration capacity of the soil, irrigation all the time in a day. Then depends on the irrigation way. If intermittent intermittent spray or spray irrigation (high degree of atomization), irrigation is best with the Sun. Not only can add moisture, but also significantly improve the microclimate and photosynthesis and transpiration and gas exchange, facilitated the coordination of water, air, fertilizer and soil thermal and vegetative organs of root and root expansion, and could lead the entire transit storage of the plant material, breathing, lawns and lush. If using water, irrigation, and so on, should be watching season, early spring, late autumn around the heel as well and the rest take twilight as much. (2) irrigation irrigation quantity should be based on the soil, growing, grass and other factors to determine. General lawn growing season drought period, takes about a week to pay 20-40mm; vigorously growing lawn in the heat and severe drought situations, need to pay 50-60mm per week or more. In General, regardless of the method, should be irrigated more than once, each time less water, maximum surface runoff that just occurred. 2, fertilizing to maintain lawn dark green leaves, grows, portions must be fertilized. Lawn plants for leaf growth and blossom-free requirements, so nitrogen is more important, response to nitrogen fertilizer is the most obvious.
