Big-ridge and double-line buckwheat cultivation method

Abstract

The present invention discloses a big-ridge and double-line buckwheat cultivation method and provides a relatively complete buckwheat cultivation method. The technical content, such as soil preparation, seed treatment, sowing, field management, pest control and the like, is standardized, and the sowing period is from the beginning of June to the middle of June; the seed consumption is 30-45 kg per hectare; big-ridge and double-line planting is adopted, the row distance is 45-50 mm, the interval between double rows is 8 mm, and 600,000-900,000 seedlings are conserved per hectare; 30-60 kg of urea, 60-120 kg of diammonium phosphate and 30-45 parts of potassium sulfate are applied to per hectare during sowing. The adoption of big-ridge and double-line planting is favorable for ventilation, light penetration and mechanized operation; with combination of scientific and reasonable matched cultivation measures, a good-quality and efficient buckwheat planting method is provided.

Description

Technical field [0001] The invention belongs to a crop cultivation technique, in particular to a large-ridge double-row buckwheat cultivation method. Background technique [0002] Buckwheat is a plant belonging to the genus Polygonaceae, with a plant height of 60-100 cm and a maximum height of about 150 cm. The leaf axils of the main stem nodes can grow first-level branches, and the first-level branch leaf axils can grow second-level branches. Three-level branches can grow under the best cultivation conditions. [0003] In the annual planting areas in the north, single-row small ridges are commonly used for sowing, with a ridge spacing of 25cm-30cm. In the late stage of buckwheat growth, poor ventilation and light conditions will affect the normal growth of buckwheat, poor pollination, and low fruit setting. In addition, buckwheat has always been treated as a drought-resistant and famine-prepared crop. Generally, buckwheat is planted when the growth period of other crops is not en...

AI Technical Summary

Problems solved by technology

[0003] In the planting areas of the north where one season is a year, single-row small ridges are generally used for sowing, with a distance of 25cm-30cm. In the later stage of buckwheat growth, the ventilation and light transmission conditions are poor, which affects the normal growth of buckwheat, poor pollination, and low fruit setting rate.

In addition, buckwheat has always been treated as a crop for drought resistance and famine preparation. Generally, buckwheat is planted when there is little rain in spring and the growth period of other crops is not enough. Extensive cultivation, extensive planting and low harvest have greatly affected the development of buckwheat production.
