在毛主席革命路线指引下,我县革命干部和贫下中农,经过三年实践,已经大面积推广了盐碱地上育桑苗的经验。1972年全县培育桑苗420亩,其中110亩播种在含盐量0.3%以内的围垦地或围堤上,一般苗高3尺、根基围度1.3寸左右,最高达8尺、根基围度2.4寸,比淡土育苗根基粗、质量好。这就打破了过去所谓含盐量0.1%以上的土地不能培育桑苗的局限性。现将技术措施介绍如下:
Under the guidance of Chairman Mao’s revolutionary line, the revolutionary cadres and the poor and poor middle peasants in our county have popularized the experience of cultivating the mulberry seedlings on saline-alkali soil in a large area after three years of practice. In 1972 the county cultivate 420 acres of mulberry, of which 110 acres planted in the salt content of 0.3% of the reclamation or embankment, the general seedling height of 3 feet, the basic circumference of about 1.3 inches, up to 8 feet, the basic circumference 2.4-inch, more light soil seedling roots, good quality. This breaks the limitation that the so-called land with salt content above 0.1% can not cultivate mulberry seedlings. The technical measures are as follows:
