Furrow film ridge planting method for sunflowers

Abstract

The invention provides a furrow film ridge planting method for sunflowers, belongs to the technical field of crop planting, and aims at solving the problems of yield reduction due to drought and Orobanche coerulescens parasitismbecause of irrigation difficulty as normally-planted sunflowers in Hetao irrigation areas are prone to irrigation lodging in the later growth period and seedlings in saline-alkali soil die due to irrigation. During sunflower planting, furrowing and fertilizing operations are innovatively completed at one time by adopting a furrowing and film mulching machine, plastic films cover the bottoms of furrows to the tops of slopes, and seeds are manually sown on the shoulders of the slope, so that the furrow-film ridge planting method integrating dew collection, rain collection, water retention, root nourishment, irrigation and drainage, lodging resistance and orobanche coerulescens resistance is formed. The method can improve the moisture conservation capacity of root layers and promote root systems to grow well, waterlogging prevention and lodging resistance are high, and plants grow well and are high in yield; and the purpose of salt inhibition in moderate saline-alkali soil can be achieved, the seedling protection rate is increased, and the Orobanche coerulescens harm is reduced in Orobanche coerulescens generation land. The technical method is beneficial to industrial application and makes a great contribution to high-quality development of the sunflower industry.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a method for planting sunflowers in furrows and ridges. Background technique [0002] As the largest sunflower production base and distribution center in the country, Hetao Irrigation District plays a key role in the development of the national sunflower industry. The Hetao Irrigation Area has a dry climate, low rainfall, and large evaporation, resulting in severe soil drought and salinization. Insufficient water supply during the sunflower growth period, especially the budding period, leads to production reduction and sunflower column is prone to occur in the arid environment. Planting sunflowers in moderately saline-alkaline lands can easily lead to physiological drought, difficulty in maintaining seedlings, weak growth, low yield, and poor benefits. Therefore, it is of great significance to alleviate the drought during the growth period of sunflower. [0003] Although ...

AI Technical Summary

Problems solved by technology

[0003] Although plastic film mulching can relieve certain drought conditions, the soil moisture content of conventional plastic film mulching methods is still at a low level during the key water demand period of crops, which limits the growth and development of crops; although irrigation during the growth period is an effective measure to solve drought conditions, but due to In the Hetao area, there are problems such as easy lodging of sunflowers during the growth period and dead seedlings in saline-alkali land. In terms of production, sunflowers are planted without irrigation during the entire growth period, and the sunflowers in the late growth period are seriously reduced due to drought.
