通过科学实验,我们体会到,盐碱地播种育苗要掌握好三个环节:1、播种季节要晚。海堡春旱风大是盐分大量上升季节,要躲过返盐高峰,播种季节要晚些,最好在六月上旬,下过第一场透雨,立即抢墒播种为好。因为这时风小,气温高,墒情好种子发芽出土容易,当苗子长到2~3寸高时已进入雨季,躲过了干旱盐碱的危害。2、培垄保墒。播种后沿播种行盖一层细沙,后封土成垄,没有沙源的可直接封土成垄,待种子发芽定撅后,及时去垄,这样做不仅能保持土壤湿润,又能防止土壤返盐和雨后板结。3、播种量要大,间苗、定苗
Through scientific experiments, we understand that sowing seedlings to salinity to master the three aspects: 1, sowing season to late. Sea Fort Spring drought is a lot of salt rising season, to escape the peak return salt, sowing season later, preferably in early June, had undergone the first through the rain, immediately grab moisture sowing as well. Because at this time the wind is small, high temperature, moisture content is good seed germination unearthed easily when the seedlings grow to 2 to 3 inches high into the rainy season, escaped the damage of arid saline. 2, Pei-care soil moisture. Seeding sowing along a layer of fine sand cover, after the closure ridge into a ridge, there is no sand can be directly buried ridge, until the seeds germination Dingzhang, in time to the ridge, this will not only keep the soil moist, but also to prevent the soil back Salt and rain after the plate knot. 3, sowing to large, thinning, Dingmiao
