Potato is the fourth most important food crop globally and is deeply loved by people. Wulanchabu is an important production base for potato seeds, commercial potatoes, and special - purpose potatoes for processing in China. The city's planting area has been stable at around 4 million mu, and the total output of fresh potatoes reaches 4.5 million tons. It is a veritable "Potato Capital of China".
From September 8th to 10th, the "2019 China Wulanchabu Potato Green Development Science and Technology Innovation Conference" jointly organized by the Chinese Academy of Agricultural Sciences, the People's Government of Wulanchabu City, the Department of Agriculture and Animal Husbandry of Inner Mongolia Autonomous Region, and the National Potato Industry Science and Technology Innovation Alliance was held in Wulanchabu City, Inner Mongolia Autonomous Region. More than 400 people participated in this conference, including local government leaders, representatives of relevant departments, project - participating units, member units of the National Potato Industry Science and Technology Innovation Alliance, potato enterprises across the country, cooperatives, and large - scale growers. Hubei Yishizhuang Agricultural Technology Co., Ltd., as a manufacturer of special slow - release and controlled - release fertilizers for potatoes, was invited to participate in this conference.
In order to explore the optimal planting schemes in different main production areas, different ecological areas, and regions with different levels of economic development, the comprehensive demonstration base for potato green development has demonstrated the integration of seven core technologies, including new green and high - quality varieties, the breeding and application of healthy virus - free potato seeds, precise micro - irrigation with integrated water and fertilizer, green prevention and control of diseases and pests, remote sensing digital remote - control monitoring, full - process mechanization, and staple food processing, as well as the optimized and improved cultivation technology for reducing the application of chemical fertilizers in potatoes and increasing efficiency.
In China, the over - application of chemical fertilizers is serious, and the fertilizer utilization rate is low. The amount of fertilizers used for fruits and vegetables is 2 - 4 times that of the world. Previous studies have found that the utilization rate of fertilizers for potatoes is generally low, resulting in certain waste and affecting the soil environment, and the yield and quality cannot develop stably.
Regarding the issue of reducing fertilizer application and increasing efficiency, the expert team unanimously believes that corresponding nutrient management strategies should be formulated in different regions to "reduce the fat" of the soil in a targeted manner, balance and optimize the proportion of soil trace elements, and meet the different nutrient needs of potatoes in each growth period. Hubei Yishizhuang Company, in cooperation with the potato expert team, has developed a special formula fertilizer that is more suitable for the growth of local potatoes according to the nutrient needs of crops, the nutrient content of the soil, and the characteristics of fertilizer supply. This can effectively improve the fertilizer utilization rate, improve the quality of crops, increase the yield, and improve soil fertility.
The field demonstration of Yishizhuang sulfur - based special slow - release and controlled - release fertilizer for potatoes with a content of 40% has achieved certain results this time.
Yishizhuang remains true to its original aspiration and forges ahead. It helps with the green development of Chinese potatoes.
