不同水肥条件对南疆紫花苜蓿品质的影响OA
Effects of Different Water and Fertilizer Conditions on the Quality of Alfalfa in Southern Xinjiang
本研究主要目的是通过控制氮肥、磷肥、钾肥的施用量以及农田灌水量,采用二次饱和D-最优设计进行苜蓿水肥耦合田间试验,测定了紫花苜蓿的粗蛋白、粗灰分、中性洗涤纤维等指标.探究不同水肥配比对阿拉尔地区紫花苜蓿品质的影响,筛选出适合在新疆阿拉尔地区种植优质紫花苜蓿的最佳水肥配比.结果表明,氮肥31.19kg·hm-2、磷肥29.84kg·hm-2、钾肥28.53kg·hm-2为最佳施肥量,1515.87m3·hm-2为最佳灌水量.本研究为我国新疆南部地区畜牧业发展提供理论依据.
This study primarily aimed to determine the optimal water and fertilizer ratios for high-quality alfalfa cultivation in the Aral region of Xinjiang by controlling the application rates of nitrogen,phosphorus,and potassium fertilizers as well as irrigation amount,using a quadratic saturated D-optimal design for a field water-fertilizer coupling experiment.The crude protein,crude ash,and neutral detergent fiber contents of alfalfa were measured.The results showed that the optimal fertilization rates were 31.19 kg·hm-2 for nitrogen,29.84 kg·hm-2 for phosphorus,and 28.53 kg·hm-2 for potassium,with an optimal irrigation amount of 1,515.87 m3·hm-2.This study provides a theoretical basis for the development of animal husbandry in southern Xinjiang,China.
