夏播春麦是北方高寒冷凉半干旱山区农业生产中的一项主要抗旱增产措施。它的特点是:在旱坡地上,在秋季或翌年早春干旱严重,春小麦不能正常播种的情况下,及时地利用雨季和有效生育期,选用适当的春麦品种进行夏播,通过科学的田间管理,获得一定产量的一项新技术。
Summer sowing spring wheat is a major drought-relief stimulation in agricultural production in the cold and cold northern semi-arid mountainous areas in the north. Its characteristics are: timely use of the rainy season and effective growth period, selection of suitable spring wheat varieties for summer sowing on the sloping land in the autumn or the following year when the drought in early spring is severe and the spring wheat can not be sown normally. Through scientific field management, A new technology to achieve a certain yield.
