红麻具有耐涝、耐盐碱的特性,在山东、河南、河北、江苏、安徽等省利用滨海盐碱土和内陆次生盐渍土种植面积已有50多万亩,一般亩产300—400斤,高的达600多斤,甚至800—1,000斤。一、红麻的耐盐强度据我们在山东麻区三年的田间试验和土壤分析,选择红麻对盐分反应最敏感的苗期作为鉴定重点,初步鉴定结果是:青皮3号红麻苗期,0—15厘米土层含盐量在0.28%以下时,幼苗子叶嫩绿,幼茎健壮,根群白色,生长正常;含盐量在0.28—0.41%范围时,麻苗受到不同程度的盐害,呈现子叶窄小,叶缘紫红色,
Kenaf has the characteristics of waterlogging resistance and salinity resistance. In Shandong, Henan, Hebei, Jiangsu and Anhui provinces, there are more than 500,000 mu of cultivated area using coastal salinized soils and inland salinized soils, and the average mu produce 300-400 kilos , Up to 600 kilos, or even 800-1,000 pounds. First, the kenaf salt-resistant strength According to our three-year field trials in Shandong Ma area and soil analysis, the choice of kenaf sensitivity of salt to the most sensitive seedling stage as a key identification, preliminary identification results are: Green Peel No. 3 seedling stage , When the salt content of 0-15 cm soil layer is below 0.28%, seedling leaves are tender green, young stalks are robust, and root group is white and grows normally. When the salt content is in the range of 0.28-0.41%, the seedling is affected by salt damage , Showing cotyledons narrow, purple margin leaves,
