Embodiment 1

[0041]The test area is located in Manshuitan Village, Minghua Township, Sunan Yugu Autonomous County, Zhangye City (E98°49′2.49″, N39°40′13.22″), which belongs to a typical temperate continental climate. The average annual precipitation in the area is 85.3mm, the average annual evaporation is 2148.8mm, the annual average temperature in the study area is 7.3°C, and the altitude is 1387.66m. The buried depth of groundwater in this area is relatively high, and the average buried depth during the growth period of pasture grass is 2.6m; the soil layer within 0-60cm is sandy loam, and the bulk density and field holding are respectively 1.4g / cm 3 , 21.2%; organic matter content, alkaline nitrogen, available potassium, and soil soluble salts in the 0-30cm soil layer were 3.13g / kg, 24.87mg / kg, 140.72mg / kg, and 7.82g / kg respectively. The soluble salt content in this area Between 5g / kg-10g / kg, it is heavy saline soil.

Abstract

The invention discloses a cultivation method for mixed sowing of forage grass in arid desert areas. The method includes the following steps: (1) soil preparation and fertilization: applying farmyard manure after soil preparation, deep tillage, insolation, ditch application of phosphate fertilizer and ploughing and leveling; (2) seed selection: selecting smooth brome grass and clear water alfalfa or red bean grass as mixed seeds; (3) seed dressing and sowing: seed dressing with a compound fertilizer agent and then drilling and sowing; and (4) irrigation and fertilization: (1) irrigation: combining the above-ground spray irrigation and micro-spray with surface spray irrigation, and mainly irrigating leguminous plants in the growth period, specifically, preforming the above-ground spray irrigation in the green returning period and branching period of forage grass each stubble; preforming micro-spray irrigation with surface spray irrigation in a bud stage, a flowering stage and a mature stage; and (2) fertilization: during the first growth period of each alfalfa crop, applying a nitrogen fertilizer of 5-7 kg / mu, 2-3 kg / mu and 2-3 kg / mu along with irrigation water. By adopting the cultivation method for mixed sowing of forage grass, the yield and feeding value of forage grass are obviously improved, water resources are saved, the water utilization rate is improved, and the sustainable development of animal husbandry in arid desert regions is facilitated.

Description

technical field [0001] The invention belongs to the technical field of pasture cultivation, and in particular relates to a cultivation method for pasture mixed sowing in arid desert areas. Background technique [0002] In recent years, with the rapid development of the domestic economy and animal husbandry, the demand for forage has been increasing. However, due to the large supply gap of forage in my country, the sustainable development of animal husbandry is seriously restricted. The development of modern animal husbandry cannot rely solely on natural pastures, but must explore high-yield, high-quality, and efficient artificial pasture cultivation methods. Artificial grassland is a special artificial plant community established by selecting suitable grass species under the strong intervention of human agricultural measures in combination with the specific ecological conditions of the location. The stability and production capacity of the community are affected by inter-spe...
