我县水稻育苗惯用的是无孔薄膜覆盖。这种育苗方法如管理不当,炼苗不及时,容易出现立枯病和青枯病,造成苗弱,违误农时,遭致减产。为了培育壮秧,一九七五年进行有孔薄膜育苗试验,一九七六年全县推广有孔薄膜育苗一万四千床,效果良好。一、有孔薄膜育苗的优点:1、有孔薄膜能自动调节床温,床内温差较小,利于培育壮秧。据曙光农场农业站在种子队于播种到出苗前,床温观测
My county rice seedling habit is non-porous film covered. Such breeding methods such as improper management, hardening is not timely, prone to blight and bacterial wilt, resulting in weak, false agricultural, was caused by cut. In order to cultivate strong seedlings, a perforated film nursery test was conducted in 1975, and fourteen thousand holes were punched in the county in 1976 to achieve good results. First, the advantages of perforated film nursery: 1, perforated film can automatically adjust the bed temperature, the bed temperature difference is small, conducive to nurturing strong seedlings. According to the dawn farm farms in the seed team before sowing to emergence, bed temperature observation
