Embodiment 1

[0039]In 2016, the experiment was carried out in Lijin County, Dongying City, where the loamy and clay-severe fluvo-aquic saline-alkali land (Shandong Bohai Huibang Agricultural Development Co., Ltd., Tingluo Town, Lijin County) belongs to the warm temperate continental monsoon climate, with four distinct seasons, sufficient sunlight, and rain. The hot season is the same, the annual average temperature is 13.2 ℃, and the annual average rainfall is 494.3mm. Clay soil, severe saline-alkali soil, soil layer thickness 40-50cm, salinity above 0.48%, organic matter content 6.96g / kg, pH value 8.5, irrigated with Yellow River water before sowing to pressurize alkali.

[0040] Cotton is selected from Lumianyan No. 37 bred by Shandong Cotton Research Center, and the seeds are selected from selected coated varieties; oil sunflower is selected from 567DW (commonly known as dwarf head) coated with seed coating agent; spring corn and summer corn are selected from Shandong Academy of Agricult...

Embodiment 2

[0062] In the second year, in the same field after the harvest of Example 1, the planting test was continued.

[0063] One group: intercropping pattern of oil sunflower, cotton and corn, adopting the method of the present invention, the steps are as follows;

[0064] Inter-annual crop rotation: repeat steps 1) to 6) of Example 1, the difference is that when the spring crops are planted, the planting belts of cotton and oil sunflower are exchanged, and after the oil sunflower is harvested, summer corn is interplanted to realize spring corn, cotton , oil sunflower and summer corn are intercropped during the year, and cotton and oil sunflower are intercropped between years.

[0065] Two groups: cotton monoculture, method is the same as embodiment 1.

[0066] Three groups: oil sunflower is cultivated alone, and the method is the same as in Example 1.

[0067] See Table 2 for the planting results of each group in the second year.

Abstract

The invention relates to an efficient planting pattern for cotton, helianthus annuus and corn intercropping and rotation in heavy chlorate clay saline-alkali soil in yellow river delta. A mode of intercropping and rotation of crops different in salt tolerance and salt absorption is adopted for the first time, a long-stalked crop (spring corn and helianthus annuus) wind strip and a green manure (summer corn) returning-to-field area are arranged, and through intercropping of annual crops of the planting mode, rational arrangement of crops for rotation, crop rotation of inter-annual crops and soil productivity cultivation and by comprehensive coordination of growth rate of different crops, efficient ecological planting of heavy clay saline-alkali soil with salt content reaching over 0.4% is realized. Annual intercropping is carried out for spring corn, cotton, helianthus annuus and summer corn, inter-annual crop rotation is carried for cotton and helianthus annuus, successive cropping obstacles of single crop are alleviated beneficially, and sustainable development of soil is guaranteed.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and relates to a high-efficiency intercropping rotation planting pattern of cotton, oil, sunflower, and corn in the saline-alkali soil of heavily chlorinated clay in the Yellow River Delta. Background technique [0002] The Yellow River Delta Efficient Ecological Economic Zone is located in the northeast of Shandong Province. Its geographical scope includes Dongying and Binzhou and some counties and cities in Weifang, Dezhou, Zibo and Yantai. The total area is 26,500 square kilometers. One-sixth, one-tenth and one-seventh of Shandong Province. [0003] From the perspective of natural resources, the area is low in altitude, high in groundwater level, thin in silt layer, and strong in capillary action. A large amount of salt contained in the parent material of marine saline soil easily rises to the surface, resulting in large-scale salinization of soil. From inland to offshore, The soil is g...
