Problems solved by technology

Sowing oats in spring is beneficial to complete their life cycle and increase yield, but dryness and strong wind in spring have become the key factors that endanger the survival of oat seedlings. Traditional oat planting methods are difficult to solve the problem of low emergence rate and survival rate in spring planting. The problem

Abstract

The invention discloses a high-yield oat cultivation method in a semi-arid region. The technology of ridge and furrow rainwater harvesting is implemented, rainfall harvested by ridges and furrows flows into planting furrows, and rainwater is superimposed in the furrows and infiltrates more deeply, so that the water content of soil is increased. Farmland crop growth microtopography is changed by the planting technology of ridge and furrow rainwater harvesting, plant root systems change in soil spatial pattern, and the use efficiency of the rainfall resource is improved. A water-retaining agent is applied at the same time, is capable of improving the soil structure, promoting granule formation and absorbing and keeping water with the weight hundreds or thousands times that of the water-retaining agent to achieve soil water storage and preservation and is capable of releasing the absorbed water when soil is arid and short of water.

Description

technical field [0001] The invention relates to the technical field of oat cultivation, in particular to a high-yield cultivation method for oats in a semi-arid area. Background technique [0002] The Datong Basin in Shanxi is located in the northeastern edge of the Loess Plateau and the intersection zone of the Taihang Mountains. It is an arid and semi-arid area with a relatively fragile ecological environment. However, its unique ecological environment and climatic conditions are very suitable for the production of miscellaneous grains. It is an important production of miscellaneous grains in China. one of the bases. In this area, oats have more extensive adaptability, and the development of oat production has important practical significance for solving the serious food security problems and regional ecological environment problems that still exist in our country. [0003] Oat belongs to Poaceae Poaaceae Avena genus. It is an annual crop with both food and grass. It can ...
