近年来,新疆蚕业生产飞速发展,桑园不断扩大。但是,由于气候干燥,土壤盐碱重,桑树育苗不(?)成活,不能满足需要。我场从一九五七年开始育桑,头三年播种69亩,均未成苗,七年累计播种面积929亩,成苗面积283亩,成苗率不过30.5％。 从几年的实践中,我们有如下几点体会: 一、土地选择 桑苗不耐盐碱,土壤总盐量超过千分之二,便很难成活。没有条件作土壤化验时,可选择如下土地来育桑:
In recent years, the rapid development of sericulture in Xinjiang, Mulberry continues to expand. However, due to the dry climate, soil salinity, mulberry seedlings do not (?) Survive, can not meet the needs. Our farm started Yulam in 1957 and sowed 69 mu in the first three years, all of which were not mature. The total sown area in the past seven years was 929 mu, the area of mature seedlings was 283 mu, but the seedling emergence rate was only 30.5%. From a few years of practice, we have the following experience: First, land selection Sangmiao not saline, soil salt exceeded two thousandths, it is difficult to survive. No conditions for soil testing, you can choose the following land to cultivate mulberry:
