High-yield sunflower culturing technology based on drip irrigation

Abstract

The invention provides a high-yield sunflower culturing technology based on drip irrigation, belonging to the technical field of crop culture. According to the invention, aiming at the biological characteristics of the sunflower, seven matched culturing technologies, namely soil selection, reasonable compact planting, early sowing at proper time, scientific fertilizing, water-saving drip irrigation, assistant pollination and in-time harvest are utilized, so that the purposes of high yield and water conservation can be achieved. The high-yield sunflower culturing technology based on drip irrigation is strong in pertinence, has the effects of water and fertilizer conservation, labor saving, high yield and high efficiency, and is wide in popularization and application prospect.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural cultivation, and relates to a high-yield cultivation technology of drip irrigation sunflowers. Background technique: [0002] Sunflower is an emerging economic crop and oil crop, an important industrial raw material, and has become the second largest oil crop in the world. Sunflower has the characteristics of drought resistance, barren resistance, and salt-alkali tolerance. Nearly two-thirds of the northern region is saline-alkali land, which is suitable for the development of sunflower production. Sunflower has strong stress resistance and wide adaptability. It can improve soil structure, reduce soil erosion, and can utilize and transform low-yield fields. It is of great significance for the development of agriculture in saline-alkaline areas and arid areas.

AI Technical Summary

Problems solved by technology

[0003] my country's water resources are short, especially in the vast northern regions, where the per capita water resources are relatively small, and the average water resources per hectare is 6810m 3 , the shortage of water seriously limits the improvement of agricultural production, but the low irrigation efficiency and waste of water are very prominent problems in the northern region

At present, most of the sunflower cultivation still adopts the traditional furrow irrigation cultivation technology, which cannot achieve the combination of high yield and high efficiency. Therefore, it seriously restricts the improvement of sunflower yield.

The traditional sunflower cultivation technology mainly has the following problems: one is that the water consumption is relatively large, which wastes water resources

The second is that the quality of sowing is poor, resulting in the lack of seedlings and broken ridges, and the emergence of seedlings is uneven

The third is that the planning of water and fertilizer is unscientific, and it cannot be replenished in time according to the law of water and fertilizer demand, and the field management is extensive.
