1墒情夏季育苗由于温度较高,苗床墒情易损失,要在厢面浇透水、厢内有明水溢出为度。一般种子要求多遍撒播,个别调整,对贵重的种中子要求在播前整好的厢面用菜耙子纵耙、横耙后再浇水,浇足水后,将种子播入耙出的十字架中,每个十字一粒种,播好后盖好盖子,以利保墒出苗。2环境夏季蔬菜育苗温度较高,暴雨较多,在种子播入苗床后,必须在苗床上搭一米高左右的阴棚,成屋架式,架上复膜,膜上压玉米秆或树枝,防日光直射和暴雨冲刷,以免将种芽晒死或冲入泥土中出苗难。
1 soil moisture summer seedlings due to higher temperatures, easy to lose seedbed moisture loss, to be in the box surface water, there is a clear water overflow in the car for the degree. The general seed requirements spread over many times, individual adjustments, the precious seed neutron requirements before sowing a good car rake vertical rake, rake and then watering, pour enough water, the seeds into rake out In the cross, every cross is a seed, and the lid is covered after it is sown so that the soil moisture emerges. 2 environment Summer vegetable nursery temperature is higher, heavy rain, the seed into the seedbed, the seedbed must take a meter or so shade shed into a roof frame, frame Fumo, membrane pressure corn stalks or branches, Anti-direct sunlight and storm erosion, so as not to sun or sprout into the soil germination difficult.
