一、西藏冬小麦栽培概况麦类作物在西藏高原历史悠久,由于封建农奴制度的摧残和禁锢,农业生产十分落后,产量很低。好的栽培方式得不到推广。解放后生产突飞猛进,蒸蒸日上。特别是1972年推广种植冬小麦以来,促进了耕作制度上的重大变革,产量显著上升。 1978年小麦播种面积达98万亩,其中冬小麦71.85万亩,占冬春麦播种面积的73.3％,占全区农作物播种面积的22.1％。并且出现了大面积亩产1000斤和1600斤以上的高产地块。江孜县农试埸1974年有一块地亩产1308斤,1975年1611.2斤,1977年达1673.2斤/亩;日喀则县扎西吉彩公社三队在1976年达到亩产1450斤;在1979年日喀则地区农科所出现了亩产1742.2斤的高产纪录。这些高产典型充分证明了西藏高原冬小麦的丰产
I. Introduction of Winter Wheat Cultivation in Tibet Wheat crops have a long history in the Tibetan Plateau. Due to the devastation and confinement of the feudal serfdom, agricultural production is very backward with low yields. Good cultivation methods can not be promoted. After the liberation of production by leaps and bounds, thriving. In particular, since the promotion of planting winter wheat in 1972, major changes have been promoted in the farming system, with a marked increase in output. In 1978, the sown area of wheat reached 980,000 mu, of which 71.85 mu was winter wheat, accounting for 73.3% of the sown area of winter and spring wheat and 22.1% of the sown area of crops in the region. And there has been a large area of 1000 kg per mu and more than 1600 pounds of high yield plots. Gyantse agricultural trial 埸 1974 a piece of land per mu 1308 kg, 1611.2 kg in 1975, up to 1673.2 kg / mu in 1977; Shigatse Jixi commune in Shigatse three communes in 1976 to achieve 1450 pounds per mu; in 1979 Shigatse There appeared a yield record of 1742.2 kg per mu in the region’s agricultural sciences. These high-yielding models have fully proved the high yield of winter wheat on the Tibetan Plateau
