1979年,青海省香日德农场一大队四中队3.91亩春小麦高产试验田,经青海省春小麦高产验收组验收,亩产达到2,026.1斤。一、气候特点:香日德农场地处柴达木盆地,小麦生育前期气温回升徐缓,能充分进行小穗分化,有利于形成大穗;生育后期,气温平稳下降,能延长灌浆期,有利于提高千粒重;日光能丰富,光质好、辐射强、昼夜温差大,大气干燥,这是夺取高产的有利因素。二、群体结构:选用76-338、7-335春小麦品种,于3月24日播种,每亩播量48斤,
In 1979, a unit of 3.91 mu of spring wheat high-yield trial field of a large squadron of a unit of Xiangjide Farm in Qinghai Province was checked and accepted by the high yielding acceptance group of spring wheat in Qinghai Province with a yield of 2,026.1 kg per mu. First, the climate characteristics: Xiangride farm is located in the Qaidam Basin, wheat warming early warming slowly, spike differentiation can be fully conducive to the formation of large spike; late growth period, the temperature dropped steadily, to extend the filling period is conducive to Improve grain weight; rich daylight, good light quality, strong radiation, large temperature difference between day and night, dry atmosphere, which is to seize the favorable factors of high yield. Second, the group structure: Selection of 76-338, 7-335 spring wheat varieties, sown on March 24, sowing 48 kg per mu,
