spread rapidly around the world, some countries and regions are strengthening trade control. For China'
food security
also brought a severe test. "Recently, at the site meeting of Beidou Navigation Digital Precision Physical Weeding New Technology in Yiling Town, Yangzhou Jiangdu District, Jiangsu Province, Professor Zhang Ruihong of Yangzhou University's
Machinery
Engineering College said that for
wheat
production, spring is the key time to increase production and maintain production. However, in the face of the impact of large areas of weeds in the field, large growers face a shortage of agricultural labor force, often overuse
herbicides
to solve
food
production problems.
, herbicide use accounts for 60% of pesticide use and has become a major source of pollution from agricultural sources. Professor Zhang Ruihong said.
wheat, rice, corn growth process, the field will produce a large number of weeds, this time need to weed. In the traditional agricultural operation period, mainly by manual removal. "But since the 1980s, due to the massive transfer of rural labor force, the continuous development of pesticide fertilizers, stem and leaf treatment agents, killer herbicides, etc. began to be used in large quantities, the amount of use is still high." Yangzhou City agronomist Ji Zhangding said that solving the problem of herbicide pollution has become a major event in China's environmental governance, is imminent.
experts, herbicide residues and toxicity than insect medicine drugs are much more, but also much stronger. The excessive use of herbicides has caused great harm to crops and the environment. For example, sulfonam is a large area of the world's internal suction type, conductive type sulfonylurea herbicide, it is very easy to ecological environment, food crop yield,
four food
safety and environmental potential harm.
In addition, in the weeding, pest control, the domestic use of a large number of manual and mobile foggy machinery and other small-scale application machinery, its operating accuracy is poor and the diameter of fog droplets, droplets easily from the surface of the leaves rolling down, resulting in nearly 70% of pesticide loss to the soil, resulting in large areas of environmental pollution.
In the view of experts, in order to solve the problem of pollution from agricultural sources, the key is to accelerate the integration of agricultural technology, mechanization of the planting process, informationization of production and operation, eco-environmental protection and greening, promote the scientific and prosperous development of Crop Cultivation in China, and ensure the sustainable development of China's agricultural products in the new era.
In recent years, with the rapid rise and vigorous development of Beidou navigation, artificial intelligence, big data, cloud computing, Internet of Things and advanced manufacturing technology, China is building a multidisciplinary and inter-integrated innovation industry chain of agricultural machinery technology, and a number of independent innovation achievements are subverting the traditional production methods of food production and food, making a number of new industries, new models and new industries.
Such as Yangzhou University Zhang Ruihong research team independently developed the Beidou navigation rotary tillage flame-sealed grass-sealing duplem machine, Beidou navigation digital pair mechanical weeding machine operation, the core technology is Beidou navigation digital precision tillage technology.
"We have been conducting joint research and development since two years ago, and according to the 2018 and 2019 community trials, wheat uses flame-blocked grass species with an effective rate of 90%, which is 5% higher than the effectiveness of herbicide-blocked grass species, and wheat rice uses mechanical precision to weed 2 times, with a total weeding efficiency of 95%." Zhang Ruihong said.
