黑龙江省农科院小麦所建所以来,培育出一大批克字号春小麦新品种。如抗旱、丰产、优质的克旱13、克丰6号等。历年播种面积占全省小麦播种面积的85%左右,这些品种为黑龙江省提供了五次大面积的品种更换,使得全省小麦单产和总产大幅度提高。本文分析了在克山生态条件下,培育出适宜不同生态区种植的春小麦新品种的原因。在此生态条件下,对小麦的主要病害、抗逆性等性状能进行有效选择,并能培育出适应强的高产品种,因此克山是培育高产春小麦品种的良好基地。
Heilongjiang Academy of Agricultural Sciences wheat built so to cultivate a large number of gram-type spring wheat varieties. Such as drought, high yield, high-quality gram drought 13, grams Feng 6. The sown area over the years accounted for about 85% of the sown area of wheat in the province. These varieties provided five large-scale varieties replacement for Heilongjiang Province, which resulted in a substantial increase of wheat yield and output in the province. This paper analyzes the reasons for cultivating new spring wheat cultivars planted in different ecoregions under the ecological conditions of Keshan Mountain. Under this ecological condition, the key diseases and stress resistance traits of wheat can be effectively selected, and strong adaptable high-yielding varieties can be cultivated. Therefore, Keshan is a good base for cultivating high-yielding spring wheat varieties.
