Problems solved by technology

Corn / alfalfa intercropping promotes the efficient absorption of phosphorus. Although it significantly inhibits the phosphorus absorption of corn, it significantly increases the overall phosphorus absorption of the system, making its absorption advantage more obvious but the phosphorus utilization efficiency is reduced. [10]
[0003] At present, there is no method for analyzing the impact of drip irrigation corn and soybean intercropping on physiological traits, root morphology and yield in Xinjiang

Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0053] 1. General situation of the test site;

[0054] The test was carried out in Xinjiang Shihezi University Agricultural College Experimental Station (45′08"N, 85′36"E) in 2018. The annual average temperature is 7.5-8.2°C, the altitude is 399m, and the active accumulated temperature of ≥0°C is 4100°C, ≥10 The active accumulated temperature of ℃ is 3650 ℃, the sunshine hours are 2318-2732h, the frost-free period is 168-171d, the annual rainfall is 180-270mm, and the annual evaporation is 1000-1500mm. It is a typical irrigated farming area. The texture is heavy loam gray desert soil, and the soil bulk density of the plow layer is 1.6g·cm -3 . The total nitrogen content of the plow layer soil is 0.89g·kg -1 , available phosphorus 0.022g kg -1 , avai...

Abstract

The invention discloses an analysis method for the result of maize and soybean intercropping in Xinjiang region. The temperature and humidity of field between rows of crops, the plant height, the rootsystem, the SPAD value of photosynthetic pigments and the yield variation are analyzed under three cultivation modes, namely, sole cropping of soybean, sole cropping of maize and soybean-maize intercropping. The method has the advantage that the principle of the influence of the intercropping pattern on the crop yield in the drip irrigation region of Xinjiang is explored, and then, the intercropping pattern is applied to the drip irrigation region of Xinjiang to increase the crop yield in the drip irrigation region of Xinjiang.

Description

technical field [0001] The invention relates to the technical field of root system morphological characteristics and yield analysis by intercropping mode, in particular to a method for analyzing the influence of drip irrigation corn and soybean intercropping planting mode on physiological traits root morphological characteristics and yield in Xinjiang. Background technique [0002] The intercropping planting technology is the crystallization of the wisdom of the working people in our country. The intercropping planting mode has been applied as early as more than 2,000 years ago. The intercropping planting has the advantages of making full use of light and heat resources per unit area, improving the microclimate of the farmland, and effectively controlling pests. Land use efficiency plays an important role in agricultural production. However, Xinjiang is located in the inland area of ​​Northwest China, with a dry climate, and drip irrigation is widely used for planting. The p...
