概括
丘陵和沟种植显著提高了干旱地区玉米-小麦系统的作物产量. 每年创建的带边缘 (EYRFBR) 优化小麦产量和质量,而带正常宽度的永久 (PRFNR) 则适合夏季玉米.
科学领域:
- 农业科学 农业科学
- 农业学是一种农业学.
- 土壤科学 土壤科学
背景情况:
- 干旱地区的农业面临着玉米-小麦双种作物系统的挑战.
- 和种植是一种抗干旱的技术,对其对这些系统中作物产量和质量的影响的研究有限.
研究的目的:
- 评估不同山脊和种植模式对旱地玉米-小麦系统中作物谷物产量和质量的影响.
- 为了比较永久性与每年创建的山脊和边界与正常的山脊宽度.
主要方法:
- 长期实验 (2004-2021) 用五种处理方法:永久/ (PRFBR,PRFNR),每年创建的/ (EYRFBR,EYRFNR) 和传统的平面种植 (CF).
- 对作物谷物产量 (2015-2021),谷物营养成分 (P,K,蛋白质) 和冬季小麦蛋白成分 (2020-2021) 的分析.
- 统计分析包括主要组件分析 (PCA) 和TOPSIS用于全面评估.
主要成果:
- 与传统的平面种植相比,所有和纹模式都显著提高了产量,特别是在干旱的年份.
- EYRFBR处理提高了小麦谷物P,K和蛋白质含量,而PRFNR降低了谷蛋白含量.
- 永久 (PRF) 的产量高于每年创建的 (EYRF),但每年创建的提高了谷物质量.
结论:
- 每年创建的脊和与边缘脊 (EYRFBR) 模式推用于干地玉米-小麦系统的高产,高质量的小麦生产.
- 永久脊与正常脊 (PRFNR) 图案更适合夏季玉米生产.
- 优化和的设计对于平衡干旱农业的产量和质量至关重要.

Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...
