“This experimental field is planted using a ‘new’ technology – ‘cotton and peanut rotation’. Peanuts are harvested through a segmented harvesting model, that is, they are pulled up first and then picked. Each peanut plant is full of peanuts. Li Qiang, director of the Xinjiang Comprehensive Experiment Station of the National Peanut Industry System and a researcher at the Economic Crops Research Institute of the Xinjiang Academy of Agricultural Sciences, said on the 8th.
In recent years, relying on the Xinjiang Comprehensive Experimental Station Project of the National Peanut Industry System and the Xinjiang Major Science and Technology Project “Research on Key Technologies for Oil Crop Germplasm Resource Collection and Excellent Gene Mining”, the Economic Crops Research Institute of the Xinjiang Academy of Agricultural Sciences The peanut industry system innovation team has established a high-efficiency rotation planting technology for cotton and peanuts to promote “cost-saving, efficiency-increasing, and green ecology” of cotton oil production.
Li Qiang introduced that the experimental field covers an area of 32 acres, with more than 750 resource materials and about 40 new varieties (lines). Among them, there are 7 acres of cotton and peanut rotation experiments. Currently, the experimental field has entered the harvesting stage.
Currently, Li Qiang leads his team to run between the fields and the laboratory every day to obtain more detailed experimental data. Li Qiang said: “Xinjiang is China’s main cotton producing area and a high-quality cotton producing area. Cotton production occupies a leading advantage in the agricultural industrial structure. However, due to the widespread phenomenon of continuous cotton cropping, the soil environment has deteriorated, and cotton yield and quality have been affected to a certain extent.”
Li Qiang said that a large amount of experimental data shows that in peanut-cotton rotation, peanut roots and rhizobia coexist in symbiosis, and about one-third of the nitrogen fixed by rhizobia remains in the soil, which can not only fertilize the soil for the next crop. Crops provide nutrition, which plays a positive role in mitigating diseases and reducing the use of pesticides and fertilizers. It promotes cotton oil income, achieves land use and nutrition coordination, and improves economic and ecological benefits.
“In the next step, the team will conduct demonstration and promotion in Xinjiang to allow this new technology to ‘come to fruition’.” Li Qiang said.
