High-yield planting method applicable to multiple sowing of oil sunflowers in northern Sinkiang region

Abstract

The invention discloses a high-yield planting method applicable to multiple sowing of oil sunflowers in a northern Sinkiang region. The method is characterized by comprising the following steps of selecting the varieties of oil sunflowers to be subjected to multiple sowing, performing sowing, arranging drip irrigation belts, irrigating seedling emergence water, managing water-nitrogen fertilizers and the like. By the adoption of line spacing and row spacing during sowing and specific operation of water-nitrogen fertilizer management, the high-yield planting method has the advantages of being high in yield, good in operability, capable of saving water resources and high in nitrogen fertilizer utilization rate and the like.

Description

technical field [0001] The invention relates to a corn planting method, in particular to a high-yield planting method suitable for multi-sowing oil sunflowers in northern Xinjiang. Background technique [0002] Oil sunflower is one of the four major oil crops widely planted in the world. Over the years, oil sunflower hybrids have been welcomed by growers and oil processing enterprises because of their advantages such as neat and consistent plants, high yield, high oil, good comprehensive traits, and uniform grain quality, and have been well received in many provinces, autonomous regions, and municipalities in my country. Widely planted. In Xinjiang, oil sunflower is the most important oil crop, and in recent years, 130,000-170,000 ha have been planted each year 2 , accounting for more than 60% of Xinjiang's oil crop planting area and about 3.5% of Xinjiang's total crop planting area. [0003] From the perspective of the production requirements of "high yield, high efficien...

AI Technical Summary

Problems solved by technology

[0004] (1) In view of the unique natural conditions of a specific region, it is difficult to specifically guide the local water and nitrogen application ratio in terms of the influence of water and nitrogen coupling on crops in other regions

[0005] (2) Blindly increasing chemical fertilizers and not paying attention to the ratio of water and nitrogen will lead to diminishing returns, and there is a huge hidden danger of polluting the environment

[0006] (3) The research on the law of fertilizer and water demand in each growth stage and annual cycle of multi-sowing oil sunflower is not thorough, and the amount of fertilization and irrigation cannot be accurately grasped, which affects economic benefits

[0008] In recent years, although the research on oil sunflower is relatively active, a large number of scholars have shown that water and nitrogen are two crucial factors affecting the yield of multi-seeding oil sunflower, but there is little research on the effect of the interaction between the two on oil sunflower. Relatively few, and most of the previous studies focused on spring sowing oil sunflowers, and the research results obtained have little reference for multiple sowing oil sunflowers
