海岛棉所生产的细长纤维,为特种工业所必需的原料,我国需要很为殷切。以往国内未大量种植,主要依赖国外进口。从自然条件来看,我国有些地区适于种植海岛棉,根据几年试验的结果,在云南、广西和南疆等地区海岛棉产量可以达到相当高的水平。现将海岛棉在这些地区的生育情况及产量品质等情况,胪列叙述以供参考。为便于比较起见,首先将世界上生产细绒棉的几个主要国家的气候条件加以叙述:一、世界海岛棉主要生产国产区的气候及产量概况:1、苏联:海岛棉主要产区在土库曼和塔吉克两共和国的南部,位于北纬37——38度;年雨量一般为100毫米,主要分布在冬春,夏季5——10月几乎无雨;4——10月分平均温度在21——23℃,7——8月分平均在26——29℃;无霜期230——240天。1956年塔吉克共和国平均每亩产籽棉308斤。2、埃及:棉区位于北纬22——31度的尼罗河流域;全为沙漠地带,气候炎热干旱,北部年雨量180
Island slender fiber produced by the special industry for the necessary raw materials, our country needs a very ardent. In the past, there was not a lot of domestic cultivation, mainly relying on foreign imports. Natural conditions point of view, some areas in our country suitable for planting island cotton, according to several years of test results, in Yunnan, Guangxi and southern Xinjiang and other regions of the island cotton production can reach a very high level. The development of the island cotton in these areas and the yield and quality of these islands are listed below for reference. For the sake of comparison, first, the climatic conditions in several major countries producing fine cottons in the world are described. First, the climate and yield profiles of the major producing areas of the world island cotton: 1, the Soviet Union: the main producing areas of island cotton in Turkmenistan And Tajikistan, two southern republics, located 37-38 degrees north latitude; annual rainfall is generally 100 mm, mainly distributed in winter and spring, summer 5 - October almost no rain; 4 - October average temperature of 21 - 23 ℃, 7 - August average at 26-29 ℃; frost-free period 230 - 240 days. In 1956, the average yield per mu of seed in the Tajik Republic was 308 pounds. 2, Egypt: The cotton area is located in the Nile basin of Latitude 22 - 31 degrees north latitude; all desert areas, the climate is hot and dry, the northern annual rainfall 180
