早稻养萍(红萍,当地叫绿萍),好处很多。(1)韶增肥改土。萍、肥结合,连续应用,土质出现三变,即僵土变酥,板土变松,白土变黑。特别是新平整土地,在施足基肥的基础上,养萍后看萍色补肥,促使地力均匀,确保当年平整,当年受益。(2)能灭草压菌。萍体覆盖水面,能消灭稻田杂草,又能抑制纹枯病菌丝活动,一般可推迟发病期7天左右,单株发病率可减轻4—15%。(3)能增产降低成本。早稻用萍,有机质增多,对水稻能起前期防暴发,中期促稳长,后期不早衰的作用,一般每亩能增产一成以上;稻麦每亩成本仅合57.5元。
Early rice Yangping (Hongping, locally called Luping), a lot of benefits. (1) Shao increase fertilizer to soil. Ping, fat combination, continuous application of soil three changes, that is, soil softening, loose soil, clay black. In particular, the new formation of land, based on the Shizujifei, after the Pingtou look Pingtong fertilizer, prompting the ground evenly, to ensure the formation of the year, then benefit. (2) can extinguish the pressure bacteria. Ping body covering the water, to eliminate rice weeds, but also inhibit Rhizoctonia mycelium activity, generally can delay the onset of about 7 days, single plant incidence can be reduced by 4-15%. (3) can increase production and reduce costs. Early rice with Ping, an increase of organic matter, the rice can play an early anti-outbreak, the mid-term stability and growth, the role of premature aging, the general increase of more than one acre per acre; rice and wheat costs only 57.5 yuan per acre.
