Abstract

Hybrid wheat is generally recognized for its outstanding stress resistance and yield stability. Under water stress conditions, it often achieves higher yield compared to conventional wheat varieties. In this study, two winter wheat hybrids from the Jingmai series were used as research objects. With conventional wheat varieties as controls, three different spring limited irrigation methods were adopted under various ecological environments to compare the population structure, leaf quality, and yield components of hybrid wheat. The results showed that: under the condition of no spring irrigation, hybrid wheat exhibited prominent drought resistance and high yield potential, with a significantly higher yield level than conventional wheat; the average water-saving index (WSI) of hybrid wheat was 1.514, and its water-saving performance was rated as extremely strong; there was no significant difference in yield between the irrigation mode of only one irrigation at the jointing stage in spring and the normal irrigation mode of irrigation at both jointing stage and flowering stage in spring; under water-limited conditions, the total stem number of hybrid wheat at the raising stage and jointing stage was 13.9% and 15.8% higher than that of conventional wheat, respectively; under the three irrigation methods of W2, W1, and W0, the tiller ear-bearing rate of hybrid wheat was 14.8%, 22.6%, and 4.8% respectively, which was also significantly higher than that of conventional wheat. The research results confirmed that hybrid wheat has prominent advantages in water-saving and drought resistance. A relatively high tiller ear-bearing rate is the basis for hybrid wheat to achieve water-saving and high yield, and panicle number is the main contributing factor for realizing stable and high yield of hybrid wheat. Improving the tiller ear-bearing capacity through moderate irrigation can create a suitable population, thereby realizing the unity of water-saving and high yield of hybrid wheat aluminum alloys are widely used in the production of agricultural machinery parts. This article discusses the technology of increasing the tensile strength of aluminum alloys under the influence of various modifying elements. Samples were cast and tested. The studies were conducted on aluminum-copper and aluminum-magnesium alloys from aluminum alloys. As a result of the tests, the tensile strength of aluminum alloys was increased by 5%-7%. Based on the results obtained, a graph was constructed showing the dependence of the number of modifying elements on the tensile strength. At the end of the article, the authors present their conclusions based on the results of the studies.
