种植密度对饲用小黑麦、饲用黑麦种子生产性能的影响
Effect of planting density on ×Triticale Wittmack and Secale cereale seed productivity
摘要
Abstract
To determine the optimal planting density for ×Triticale Wittmack and Secale cereale seed productivity in the Hebei Plain Farming Area, the effect of planting density was studied at Hujiachi Town, in Hengshui city, Hebei Province during 2014-2016.The results indicated that planting density significantly affected ×Triticale Wittmack and Secale cereale seed production in various ways: seed yield, heading rate, kernel number per spike, thousand-seed weight and susceptibility to lodging.The optimal planting density of ×Triticale Wittmack and Secale cereale was 1.1 million·ha-1 basic seedling in October on the Hebei plain, and it would be appropriate to sow less S.cereale when planted alone under the same conditions.Under optimal seeding density, the seed yield of ×Triticale Wittmack was more than 4 300 kg·ha-1 and the seed yield of S.cereale was more than 3 900 kg·ha-1;and both species showed good performance with light lodging, high thousand-seed weight, full seed, and good commodity.关键词
