不同肥料配施方案对荞麦籽粒品质影响(英文)

目的]该研究旨在提高荞麦(Fagopyrum esculentum)籽粒口感与品质。方法]采用4因素5水平二次正交旋转组合设计方案进行施肥,分别建立氮肥、磷肥、钾肥和有机肥与荞麦籽粒中可溶性糖和蛋白质的4元2次回归方程。结果]通过回归方程分析得出:适当增施P肥,同时N肥和有机肥比例为1:140时,可以提高荞麦种子中蛋白质和可溶性糖的含量。通过计算机模拟方程寻优得出,荞麦种子中可溶性糖含量和蛋白质含量都较高的最优施肥方案是:N:535.35-581.10kg/hm~2;P2O5:69.511 5-71.359 5 kg/hm~2;K2O:249.525-270.975 kg/hm~2;有机肥:76 590-80514 kg/hm~2。氮肥、磷肥、钾肥和有机肥的最优施肥比例约为8:1:4:1 114。结论]该研究为生产口感佳、营养高、品质优的荞麦产品提供科学依据。

Effect of Different Fertilization Patterns on Buckwheat Seed Quality

Objective] This study aimed to improve the taste and quality of buck-wheat (Fagopyrum esculentum) seeds. Method] Buckwheat seeds were fertilized by using a quadratic orthogonal rotation combination design to establish quaternary quadratic regression equations between N, P, K, organic fertilizers and soluble sug-ar, protein contents in buckwheat seeds. Result] According to the regression equa-tions, appropriately increasing the application amount of P fertilizer and maintaining the ratio of N fertilizer to organic fertilizer at 1:140 could improve soluble sugar and protein contents in buckwheat seeds. By simulation optimization using a computer, in order to ensure high soluble sugar and protein contents in buckwheat seeds, the optimal fertilization patterns of each fertilizer were: N, 535.35-581.10 kg/hm2; P2O5, 69.511 5-71.359 5 kg/hm2; K2O, 249.525-270.975 kg/hm2; organic fertilizer, 76 590-80 514 kg/hm2. The optimal fertilization ratio of N, P, K and organic fertilizers was 8:1:4:1 114. Conclusion] This study provided scientific basis for producing buck-wheat products with good taste, high nutrition value and excel ent quality.
