Problems solved by technology

[0008] The purpose of the present invention is to solve the problem of low utilization efficiency of light and temperature resources of winter wheat and summer corn in the Huanghuaihai region due to the lack of annual overall management of winter wheat and summer corn cultivation management in production, and the misunderstanding of heavy wheat and light corn. Excessive plowing in the wheat season, neglect of seedbed leveling in the corn season, resulting in a large loss of surface water, and provide a "double less tillage" high-efficiency cultivation method for wheat and corn

Embodiment 1

[0025] This example was carried out in 2017 / 2018 at the Yueyang Agricultural Cooperative, Mazhuang Town, Daiyue District, Tai'an City. The soil of the plot is loamy and has irrigation conditions. The wheat variety used for the test is Jimai No. 44. It was sown on October 10, 2017. The row spacing of wheat was 18 cm, the sowing rate was 10 kg / mu, and the sowing depth was 5 cm. Less tillage, fertilization, sowing, and suppression are completed at one time, and the cost of sowing wheat with less tillage is 60 yuan / mu. From late November to early December 2017, wheat entered the overwintering period, and the daily average temperature was stable at about 3°C ​​for overwintering water irrigation. Canal irrigation and pipeline irrigation were combined to irrigate between wheat rows, and the irrigation water consumption was 40m³ / mu. Around March 20, 2018, it entered the jointing period, and the second irrigation was carried out. The combination of channel irrigation and pipeline irrig...

Embodiment 2

[0037] This example was carried out in the experimental field of Dezhou Academy of Agricultural Sciences in Shandong Province in 2017 / 2018. The area of ​​the experimental field is 2000 square meters. ), sowed on October 08, 2017, the wheat row spacing was 18 cm, the sowing rate was 12 kg / mu, and the sowing depth was 4 cm. Finally, less tillage, fertilization, sowing, and suppression are completed at one time, and the cost of less tillage and sowing of wheat is 60 yuan / mu. From the end of November to the beginning of December 2017, the wheat entered the overwintering period. When the daily average temperature was stable at about 3°C, the overwintering water irrigation was carried out. The combination of channel irrigation and pipeline irrigation was used to irrigate the wheat rows, and the irrigation water consumption was 40m³ / mu. Around March 20, 2018, the wheat began to enter the jointing stage, and the second irrigation was carried out. The channel irrigation and pipeline ir...

Abstract

The invention provides a wheat and corn year-round 'dual minimal tillage' cultivation method. The method makes full use of an existing tillage way to the greatest extent, and by tillage way change, light, temperature and moisture management of double crops are optimized and integrated, and water-fertilizer complementation, year-round overall planning and efficient utilization of the double crops are realized. The method includes steps: in a wheat planting season, after the crop in the last season is harvested in a Huang-Huai-Hai wheat area, performing stubble cleaning and leveling on land surface, and adopting a no-tillage stubble covering precision seeder for minimal tillage sowing of wheat, wherein the deep scarification depth is 45cm, the seedling belt leveling width is 8cm, the wheat sowing depth is 5cm, and the seed fertilizer applying depth is 15cm; in a corn planting season, after the wheat in the last season is harvested in the Huang-Huai-Hai wheat area, performing stubble cleaning and leveling on land surface, adopting the no-tillage stubble covering precision seeder for minimal tillage sowing of corns, wherein the deep scarification depth is 25cm, the corn seedling belt leveling width is 6cm, the corn sowing depth is 3cm, the seed fertilizer applying depth is 10cm, and the corn row spacing is 12cm.

Description

technical field [0001] The invention relates to a cultivation method of wheat and corn, more precisely, a cultivation method of "double and less tillage" for every year of wheat and corn, and belongs to the technical field of crop planting. Background technique [0002] Wheat and corn are important food crops in my country, and their largest production areas are concentrated in the Huang-Huai-Hai area. The annual sowing area of ​​wheat in this area is about 12.3 million hectares, accounting for 53.6% of the country's wheat area, and the total output accounts for 64.8% of the country's total; The perennial sowing area of ​​corn is about 7.47 million hectares, accounting for 32.7% of the country's corn area, and the total output accounts for 35.5% of the country. The Huang-Huai-Hai area belongs to the warm temperate semi-humid climate type, with a frost-free period of 170-220 days, abundant light and temperature resources, and a shortage of water resources, and the precipitatio...
