摘　　要：在防雨栽培条件下,对陕西省东渭北旱原、长武和省西旱肥地与补充灌溉地区小麦旱地品种观察的结果表明:不同地区旱地小麦品种的生育时期、株高、产量、籽粒蛋白质含量因素的变化、与地区、品种投产早晚及土壤水分含量关系密切,可为品种选育及抗旱栽培提供参考。防雨栽培进行地表锯末覆盖,用水经济,但必须与培肥地力相结合。Under the rainproof conditions observations are made of rainfed wheat varieties cultivated in the east part of weibei Rainfed Highland of Shaaxi Province and in Changwu County and in the fertile fields in the supple-mentary irrigation region in the west of the province. Results show that the variations of the growth and development stages of wheat, plant heights, yields and protein contents in grains are closely related to the regions, early and late use of wheat varieties as well as soil moistures, thus, providing the references for wheat seed selection and drought-resistant cultivation. The rainproof cultivated fields mulched with saw-dusts can save water and must also be combined with the betterment of soil fertility.
