Problems solved by technology

North China is the main grain producing area in my country, but the annual distribution of precipitation is uneven, most of which are concentrated in summer, and the winter and spring are dry and rainless, which obviously cannot meet the water demand of winter wheat in the traditional wheat-jame rotation mode. In order to meet the demand of winter wheat The amount of water, which is usually irrigated by pressure extraction of groundwater, has led to serious overexploitation of groundwater in North China

Embodiment 1

[0022] In 2019, the experiment was carried out at the Qianli Village Experimental Base (37°41′N, 116°37′E) of the Wuqiao Experimental Station of China Agricultural University. The time sequence is as follows figure 1 shown.

[0023] The spring mung bean is "BL 13-645" bred by the Baicheng Academy of Agricultural Sciences in Jilin Province. The seeds are soaked in 35°C water to accelerate germination before sowing, and the seeds are dressed with rhizobia fertilizer, and 2 kg of rhizobia fertilizer is applied per mu.

[0024] Irrigate the bottom water on March 27, 2019, and irrigate 75m per mu of land 3 , after drying, spread the base fertilizer, after spreading the base fertilizer, turn the ground 25cm with a tractor, pour the fertilizer into the soil of the plow layer, and finally level it. The fertilizer applied is urea 130kghm -2 , superphosphate 375kghm -2 , potassium sulfate 300kghm -2 , to ensure that the base fertilizer composition and content are 60kg N hm -2 , 172...

Embodiment 2

[0037] In 2019, the experiment was carried out at the Qianli Village Experimental Base (37°41′N, 116°37′E) of the Wuqiao Experimental Station of China Agricultural University.

[0038] The spring mung bean is "BL 13-645" bred by the Baicheng Academy of Agricultural Sciences in Jilin Province. The seeds are soaked in 30°C water to accelerate germination before sowing, and the seeds are dressed with rhizobia fertilizer, and 1.5 kg of rhizobia fertilizer is applied per mu.

[0039] Irrigate the bottom water on March 31, 2019, and irrigate 78m per mu of land 3 After drying, spread the base fertilizer. After spreading the base fertilizer, turn the ground 20cm with a tractor, pour the fertilizer into the soil of the plow layer, and finally level it. The fertilizer applied is urea 130kghm -2 , superphosphate 375kghm -2 , potassium sulfate 300kghm -2 , to ensure that the base fertilizer composition and content are 60kg N hm -2 , 172.5kg P 2 o 5 hm -2 and 156kgK 2 Oh -2 , sow...

Embodiment 3

[0043] In 2019, the experiment was carried out at the Qianli Village Experimental Base (37°41′N, 116°37′E) of the Wuqiao Experimental Station of China Agricultural University.

[0044] The spring mung bean is "BL 13-645" bred by Baicheng Academy of Agricultural Sciences in Jilin Province. The seeds are soaked in 40°C water to accelerate germination before sowing, and the seeds are dressed with rhizobia fertilizer, and 3 kg of rhizobia fertilizer is applied per mu.

[0045] Irrigate the bottom water on March 27, 2019, and irrigate 73m per mu of land 3 , after drying, spread the base fertilizer. After spreading the base fertilizer, use a tractor to plow the ground 30cm, pour the fertilizer into the plow layer soil, and finally level it. The fertilizer applied is urea 130kghm -2 , superphosphate 375kghm -2 , potassium sulfate 300kghm -2 , to ensure that the base fertilizer composition and content are 60kg N hm -2 , 172.5kg P 2 o 5 hm -2 and 156kgK 2 Oh -2 , sowed on Apr...

Abstract

The invention discloses a water-saving and high-income crop rotation method for spring mung beans and summer corns in North China, and belongs to the technical field of agricultural planting. A springmung bean-summer corn rotation mode is introduced in North China to replace a traditional wheat-corn rotation mode, the spring mung beans are used as preceding crops, and the summer corns with the short growth period are used as afterreap crops. The spring mung beans are relatively strong in ecological adaptability and have the certain drought resistance, and straws returned to field after harvesting have the soil fertilizing effect. The rotation mode is beneficial to water saving and fertilizer saving, the single rotation mode is broken, diversified planting systems are constructed, and theincome of farmers is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a water-saving and high-income crop rotation method of spring mung beans and summer corn in North China. Background technique [0002] Soybean crop rotation is an important way to develop sustainable agriculture, and it is also the essence of traditional agriculture in my country. This model is conducive to increasing crop yield, improving resource utilization, maintaining farmland biodiversity and reducing the use of pesticides. North China is the main grain-producing area in my country, but the annual distribution of precipitation is uneven, most of which are concentrated in summer, and the winter and spring are dry and less rainy, which obviously cannot meet the water demand of winter wheat in the traditional wheat-jame rotation mode. The amount of water is usually irrigated by pressure extraction of groundwater, which has led to serious overexploitati...
