Embodiment 1

[0088] The soybean variety used in this test is Mengdou 30, and the test area is Changfa Village, Xinfa Township, Arong Banner, Inner Mongolia.

[0089] 1. Plot selection

[0090] The experimental base of Changfa Village, Xinfa Township, Arong Banner, Inner Mongolia is black soil, with an experimental area of ​​2,000 mu. The test site is a whole village transfer plot and a concentrated contiguous plot. The first crop of the experimental land was potato.

[0091] 2. Land preparation and fertilization

[0092] Apply decomposed cow dung in spring (organic matter content 40%, moisture content ≤30%, total nitrogen, phosphorus and potassium nutrients content is about 4.5%) 70,000kg / hm 2 , Diammonium phosphate 350.0kg / hm 2 , Urea 100kg / hm 2 , Potassium chloride 100kg / hm 2 . After applying the base fertilizer, land preparation and plowing are carried out, and the plowing depth is 280mm. After the soil is plowed and loosened, the rake is leveled, and the plow layer soil should reach the sta...

Abstract

The invention provides a wide-narrow row alternate cultivation method for soybean in arid areas, which relates to the technical field of plant cultivation. The method includes the steps of soil preparation and fertilization, ridging before sowing, seed treatment, sowing, field management and harvesting. High and large ridges are constructed during the step of ridging before sowing, namely, the height, width and the like of the ridges are greater than those of traditional ridges for three-ridge cultivation. Through combination of reasonable close planting in a wide-narrow row alternate way during sowing, application of plant growth regulators during field management and other measures, the relationship between vegetative growth and reproductive growth is coordinated, and the growth and development period of soybeans is controlled, so that the yield of soybean is increased by above 15%, and ridge sealing is carried out 3-4 days earlier. The wide-narrow row alternate cultivation method for soybean in arid areas is suitable for large-scale mechanized operation, and thus, reduces the production cost.

Description

Technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a soybean wide and narrow row cultivation method used in arid areas. Background technique [0002] The three northeastern provinces of China and the soybean oil crop area in Inner Mongolia are important grain production areas and commodity grain and oil bases in China, and they play an important role in the national grain and oil security strategy. Soybeans are rich in protein and oil and have high nutritional value. The basic consumption methods are edible (making soybean products, etc.) and oil extraction (production of soybean oil and soybean meal, and soybean meal is the main raw material for animal husbandry). With the increase of China's population, the development of the domestic economy, and the gradual trend toward high-protein dietary structure, soybean consumption will continue to grow steadily for a long time. [0003] At present, many countries in the world have...
