伊宁、霍城两县一九七六年秋播种冬麦74万亩,一九七七年返青后调查,死苗面积达17万亩,占冬麦总播面积23％,其中需要翻耕改种的有7万多亩,占总播面积9.8％。 我们在调查中发现,凡较晚播种的(九月下旬及以后)比较早播种的(九月中旬及以前)死亡少而轻,倒茬地比连作地死亡轻,播种质量好的比质量差的死亡少,进行药剂拌种的比不拌种的死亡轻,冬性强的品种比半冬性品种死亡轻。
In the autumn of 1976, Yining and Huocheng County planted 74 million mu of winter wheat. In 1977, they returned to green and investigated 17,000 mu of dead seedlings, accounting for 23% of the total sowing area of winter wheat. There are 70,000 acres of species, accounting for 9.8% of the total sowing area. We found in the survey that those who planted later (late September and later) were seeding earlier (mid-September and earlier) with less and less fat, stubble than lightly stubble, and poor quality of sowing Less death, less seed dressing than the non-dressing death, winter winter strong varieties of death than semi-winter light.
