Disclosed are a cleanser for a slit coater, a slit coater for manufacturing a display device and a manufacturing method for a display device. The cleanser for the slit coater comprises propylene glycol mono-methyl ether in an amount of about 70 to about 90 wt %, propylene glycol mono-methyl ether acetate in an amount of about 5 to about 20 wt %, and ethyl(3-ethoxy)propionate in an amount of about 5 to about 20 wt %.

The invention relates to a drying method of ionic liquid, and especially relates to a deep drying and dewatering method for the ionic liquid. The method comprises the following steps: mixing an ionicliquid to be dried with a water removal agent, and carrying out azeotropic water carrying, wherein the water removal agent is one of n-butyl acetate, isoamyl acetate, ethyl propionate and n-propyl propionate. By selecting the specific water removal agent and the specific water removal process, the purpose of reducing the water content of the ionic liquid is achieved, and the obtained low-water-content ionic liquid is high in purity and yield. According to the deep drying and dewatering method, the water content of the ionic liquid can be reduced to the maximum extent, residues of the water removal agent can be avoided to the maximum extent, and the purity of the ionic liquid is guaranteed; meanwhile, the yield of the obtained ionic liquid with low water content is extremely high. The deepdrying and dewatering method is simple and convenient in process, simple in equipment, high in drying efficiency and low in cost, and has a good application prospect.

The invention relates to a method for improving the germination rate of forage grass seeds under salt stress, in particular to a method for improving the germination rate of the forage grass seeds under salt stress by treating the forage grass seeds with a calcium propionate solution having a concentration of 0.1-1.0%. The method comprises the following steps: adding a neutral salt solution and a calcium propionate solution into a culture dish paved with double-layer filter paper, putting leguminous grass seeds having been subjected to surface disinfection into the culture dish, and carrying out a germination test in an illumination incubator with a constant temperature of 25 DEG C. The method for improving the germination rate of the forage grass seeds under the salt stress can greatly improve the germination rate of the forage grass seeds under the salt stress condition, is mildew-proof and bacteriostatic, can prevent the occurrence of forage grass diseases to a certain extent, and is safe, effective, green and environment-friendly.
