Method for planting oat grass by utilizing pointer type irrigated area arid corner of arid region

Abstract

The invention relates to the technical field of artificial grassland planting and in particular relates to a method for planting oat grass by utilizing a pointer type irrigated area arid corner of anarid region. The method comprises the following steps: selecting oat seeds, treating the seeds, carrying out land preparation and fertilizer application, sowing the seeds, carrying out field management and harvesting the oat grass. In the step of sowing the seeds, a sowing region is the pointer type irrigated area arid corner and the seed sowing amount is 16 to 17kg / Mu; a sowing period is a periodafter a sowing period of crops in an irrigated area; the sowing depth is 5 to 6cm and the drill spacing is 14 to 16cm. According to the method provided by the invention, the characteristics of strongdrought resistance, high water utilization efficiency and rapid growth of oat are utilized and are combined with reasonable application of phosphorus fertilizer, i.e., basic fertilizer, and the growth of roots and the increasing of tillering are improved, so that the drought resistance of seedlings in a growth process is improved and the increasing of the tillering number of the oat grass is facilitated; meanwhile, a dense planting technology is adopted, ridges are rapidly sealed and a population photosynthesis effect is increased, so that the accumulation of biomasses is facilitated. The technology provided by the invention facilitates the utilization of fertilizer and cultivated land resources and the production of local high-quality feeding grass is improved.

Description

Technical field [0001] The invention relates to the technical field of artificial grassland planting, in particular to a method for planting oat grass by using dry corners of pointer irrigation areas in dry areas. Background technique [0002] Arid and semi-arid areas in China refer to areas with aridity greater than 1.50, and rainfall is generally less than 400mm, which is the main pastoral area in my country. In the arid and semi-arid alpine regions of northern my country, many frost-free periods are less than 100 days, and most of the regions are irrigated agriculture. Dry corners are a new type produced in the construction of farmland water conservancy facilities in cold regions of northern my country. Because pointer-type sprinkler irrigation equipment is mostly self-propelled sprinkler irrigation machines, the irrigation area is round, resulting in dead corners for irrigation in the four corners of the square land. It is the dry corner. Such land area accounts for 21.5% of...

Problems solved by technology

However, this part of the land has been in a semi-abandoned or abandoned state. Even if the same crops as those in the irrigation area are planted, because the water supply cannot be satisfied, there is basically no harvest and income, resulting in the loss of fertilizers and the waste of arable land and resources.

There is currently no technology for growing oats using dry horns
