我们农场位于渤海之滨,属于退海平原,地势低洼,地下水位高,盐碱较重,土壤板结,通透性差,以往水稻黑根严重,不易育成壮秧。从1973年起学习新开农场草袋片育苗经验(新开农场《草帘育壮秧》经验,本刊1975年第2期刊介过—编者),经试验推广效果显著。1975年全场推广隔离层育苗48,000床,占总育苗床数的75%。这一育苗法由于秧床铺上草帘能隔离盐碱,提高床温,通透性好,育出的秧苗壮
Our farm is located in the coast of the Bohai Sea, belonging to the sea back plain, low lying, high groundwater level, heavy salt, soil compaction, poor permeability, black rice in the past serious, not easy to grow strong seedlings. From 1973 onwards to learn the new farm baguette breeding experience (new farm “straw curtain breeding strong seedling experience”, published in 2 of 1975 issue - editor), the experimental promotion effect is remarkable. In 1975 the audience to promote isolation seedling 48,000 beds, accounting for 75% of the total number of seedlings. This nursery law because the seedbed covered straw curtain can isolate saline, improve bed temperature, good permeability, raised young seedlings
