Method for planting winter wheat on concave-convex ground surfaces

Abstract

The invention relates to the technical field of crop planting, in particular to a method for planting winter wheat on concave-convex ground surfaces. The method comprises the steps: performing interval and deep loosening on soil within a week after a former crop of wheat is harvested, performing ridging in areas which are not loosened deeply, performing ditching in deeply loosened areas, and covering the interior of ditches with crop straw so as to form concave-convex ground surfaces and a soil-gas barrier interface and promote gathering and accumulation of rainwater in the soil; controlling weeds with herbicide in the summer slack season; performing seed dressing by using fungicide or/and pesticide before wheat sowing is conducted, performing sowing at an equal row spacing and an equal furrow width, and performing integrated operation of fertilization, strip rotary tillage, sowing and repression so as to achieve wheat planting on the concave-convex ground surfaces; performing chemicalweeding in early winter; performing spraying of a plant growth regulator and top dressing at green-returning and jointing stages; and at a heading to flowering stage, performing combination of one spray of a foliar fertilizer with three prevention. According to the method, negative impact of water and fertilizer stress on growth and development of dry land wheat is reduced by modifying the soil,performing straw covering for rainwater collection and soil moisture conservation, adopting concave-convex ground planting, and performing localized fertilization in root zones, so that the material production capacity and utilization efficiency of water and fertilizer are improved, and the yield of wheat is increased stably.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a convex-concave planting method of winter wheat. Background technique [0002] Winter wheat is the main food crop in dryland areas in my country. Due to the lack of precipitation, lack of supplementary irrigation, poor soil and difficulty in topdressing in dryland, the yield of dryland wheat is low and unstable, and the efficiency of water and fertilizer use is low. Therefore, exploring water-conservation cultivation and nutrient management measures that can synergistically increase yield and water and fertilizer use efficiency is crucial to the sustainable development of the wheat industry and the protection of national food security. Contents of the invention [0003] The purpose of the invention is to provide a convex-concave planting method for winter wheat, so as to improve the utilization rate of water and fertilizer in dry land and increase the yield of wheat. ...
