Embodiment 1

[0040] Combined with the accompanying drawings, the establishment of micro-irrigation water collection system, the specific steps are as follows:

[0041] Select the slope of the mountain body with a slope of 35-60° and the top of the hill or mountain 1 that is relatively dry to set up a sump 2, and the plot within 2-3 meters around the sump 2 is repaired into a concave surface type 3, and a ground cover plant 4 is planted at the concave surface; The water pipeline 5 connects the sump 2 with the water storage container 6 positioned at the side of the terraced field 7, the vertical distance between the terraced field 7 and the mountain top is 10-18 meters, and the water storage container 6 is located at 1-2 meters of the terraced field 7; The water pump 12 connects the water storage container 6 and the 10-toothed pipeline; the planting field 7 is divided into planting rows 9 with a width of 1.5 to 2.5 meters with hollow bricks, and the hollow bricks are 15 to 20 centimeters high...

Abstract

The invention discloses a micro-irrigation planting method for alfalfa. The method comprises the following steps that 1, seeds are selected and treated; 2, land is selected and prepared; 3, base fertilizer is applied; 4, a water collecting pond is built, and a water conveying pipeline is laid; 5, a water storage container is arranged beside the land; 6, a micro-irrigation containing foundation is built; 7, planting ditches are dug; 8, water absorption compounds are laid in the ditches; 9, sowing is carried out in good time; 10, weeding and topdressing are carried out; 11, pest control is carried out; 12, cutting is carried out. The alfalfa is planted based on the micro-irrigation technology, and the advantages of being high in emergence rate and survival rate, high in acre yield and good in alfalfa quality are achieved.

Description

technical field [0001] The invention belongs to the technical field of pasture micro-irrigation planting, and in particular relates to a method for micro-irrigation planting of alfalfa. Background technique [0002] Dingxi City, Gansu Province belongs to the hilly and gully area of ​​the Loess Plateau, which is the lower limit area of ​​rainfed agriculture in Northwest China, and is a typical ecologically fragile area. Its climate belongs to the semi-humid to mid-temperate semi-arid zone in the southern temperate zone, with an average annual rainfall of 350-600 mm. Agricultural production mainly relies on natural precipitation, and the distribution of precipitation is uneven. Most of the precipitation is from July to September. Most of the precipitation is ineffective and micro-effect precipitation or heavy rain less than 5 mm. Runoff loss and evaporation loss coexist, which is not conducive to crops. Effective absorption of moisture. Moreover, due to excessive human econo...
