Development of sugarcane intercropping peanut cultivation technology by Guangxi Academy of Agricultural Sciences

"We made peanuts among the farmers' sugarcane fields in Zhanjiang. The effect of the peanuts was not ideal for many years. The peanuts were easy to empty. Today, the results of the peanuts in Wuxuansu root cane intercropping are full and full. We must learn from the experts in Guangxi." Peanut industry technology system breeding post scientist, Guangdong Academy of Agricultural Sciences Crop Institute Liang Xianqiang researcher praised the sugarcane intercropping peanut cultivation technology developed by Guangxi Academy of Agricultural Sciences.

Recently, the on-site observation of sugarcane intercropping peanut cultivation technology was held in Luxin Town, Wuxuan County. 37 domestic authoritative peanut experts witnessed the success of Guangxi Sugan sugarcane intercropping peanut cultivation technology. The 200-acre perennial cane and the new planted sugarcane in the village of Luxin Town and Lulai Town are lush and green, and the flower growth potential of the intercropping is normal. On-site measurement shows that the peanut per mu intercropping yields 81-87 kg per mu, and the new per plant intercropping peanut yield is as high as 146.77 kg.

Wei Yangui, a villager from the village, told the reporter: "The area of ​​the farmland has not changed. Because of the sugarcane intercropping technology, in addition to the sugarcane income, it has harvested more peanuts. The peanuts cost 10 yuan per kilogram, and the income per mu is more than 500 yuan. Thanks to Tang experts."

Wei Yangui praised Tang experts as researcher of Guangxi Academy of Agricultural Sciences and Tang Ronghua, a post-scientist in the national peanut industry technology system. He introduced that as early as 2011, his team began to test the technology of sugarcane intercropping peanuts. The biggest highlight of this acceptance is that the peanut can also be harvested well. This is the first in the country. Under normal circumstances, in the conventional sugarcane and other row spacing planting mode, some new peanut planting peanuts are harvested, but the peanuts have less results and are prone to imperfections or empty shells; however, the peanut intercropping with peanuts has not been successful. In order to break through the difficulties, the Tang Ronghua team worked hard to change the sugarcane planting mode and balance fertilization. After repeated trials, they explored a set of mature and standardized cultivation techniques and formed the local standards of Guangxi. The innovations include the use of wide and narrow rows of sugar cane, wide line of 1.8 meters, narrow line of 0.6 meters, and peanuts between sugarcane wide rows. This spacing allows sugar cane and peanuts to make maximum use of natural resources such as sunlight, atmosphere and water. Improved the ability of sugarcane and peanuts to resist pests and diseases. In terms of fertilization, we have found a balanced fertilization technology suitable for acid soils in the south, and have been demonstrated in Wuxuan, Tianyang, Longzhou and other places. The result is that sugar cane production is equivalent to conventional planting, and it can also collect more peanuts.

It is worth mentioning that sugarcane intercropping peanuts, because peanuts have biological nitrogen fixation, can turn nitrogen in the air into nitrogen fertilizer, which can reduce the use of chemical fertilizers and pesticides. It is an efficient and environmentally friendly planting method.

Liao Boshou, director of the Oil Crops Research Institute of the Chinese Academy of Agricultural Sciences, said that Guangxi's cultivation technology is leading the country, can effectively increase the supply of agricultural products, significantly increase farmers' income, and promote the green development of agriculture, so it is worth promoting.
