强筋小麦新品种龙麦77高效生产技术模式研究
Research on High-Efficiency Production Technology Model of New Strong-Gluten Wheat Variety Longmai 77
摘要
Abstract
Inorder to establish a high-efficiency production technology model for the high-quality strong-gluten wheat variety Longmai 77,field experiments were conducted from 2023 to 2024 at the National Modern Agricultural Science and Technology Demonstration and Exhibition Base of Heilongjiang Academy of Agricultural Sciences(black soil with relatively good basic fertility).The study systematically investigated the effects of three nitrogen fertilizer(seed fertilizer)treatments,three planting density treatments,and four chemical control regulators and foliar fertilizer treatments on yield and quality.A randomized block design with three replications was adopted.By measuring yield,test weight,grain protein content,sedimentation value,and six other major quality indicators,combined with correlation analysis,the optimal treatment combination was identified.The results showed that the N2 treatment(pure N 90 kg·ha-1,base fertilizer+seed fertilizer),A1 treatment(650 plants·m-2),and B4 treatment(spraying Zhenxi selenium-rich foliar fertilizer at a concentration of 4 mL mixed with 2 kg water,applied once at the tillering stage,jointing stage,and heading stage,respectively)were the optimal treatments,which could simultaneously improved yield and quality.Based on the comprehensive experimental results,a high-efficiency production technology model for Longmai 77 that balances yield and quality were constructed.The core technical points are as follows,application of N(base fertilizer+seed fertilizer)90 kg·ha-1,P2O5 75 kg·ha-1,K2O 45 kg·ha-1,planting density of 6.5 million plants·ha-1,and spraying Zhenxi selenium-rich foliar fertilizer at key growth stages.This model can help realize the high-quality and high-efficiency production potential of strong-gluten wheat Longmai 77 in the spring wheat region of Northeast China.关键词
