On September 29th, the autumn sun gently sprinkled on the fields of Wuzhuang Village, Weisengzhai Town, Guantao County, Handan City, Hebei Province, covering this golden land with a warm glow, and the air was filled with the fresh smell of earth and corn. Under the guidance of the Cultivated Land Quality Monitoring and Protection Center of the Ministry of Agriculture and Rural Affairs, the Cultivated Land Quality Monitoring and Protection Center of Hebei Province, Hebei Agricultural University, and the Guantao County Agriculture and Rural Bureau, Henan Xinlianxin Chemical Industry Group Co., Ltd. (hereinafter referred to as Xinlianxin Group) hosted the 2nd Huanghuaihai Summer Corn Area New Efficient Humic Acid Fertilizer (Zhengnutrient) Observation and Measurement Activity, the actual performance of the new high-efficiency humic acid fertilizer in corn production was announced. Under the same management method, the yield of corn increased by 16.9%, and the yield increased by 210 kg/mu (calculated according to 14% moisture). Experts who came to the scene at the meeting sighed: "The corn harvest here is too early, and it is harvested in the milk maturity period, if it is appropriately harvested late for ten days, and then harvested in the late maturity period, the yield per mu can be increased by about 50 kilograms, and the yield increase in high-yield fields will be greater, and there will be more dazzling performance!" ”
The purpose of this event is to let more dealers and large planters master more scientific corn high-yield cultivation and fertilization technology, understand the development trend of new and efficient fertilizers, and create higher planting income, attracting more than 300 dealers and large planters from Guantao, Nangong, Ningjin and other places to observe and learn.
Protecting the lifeblood of food production
Ma Changbao, Chief Agronomist of the Cultivated Land Quality Monitoring and Protection Center of the Ministry of Agriculture and Rural Affairs, pointed out that soil organic matter is the core indicator of the basic soil fertility level of cultivated land, and improving the soil organic matter of cultivated land can effectively improve soil structure, promote nutrient transformation and utilization, and enhance soil biodiversity. The results show that the average increase of soil organic matter is 1‰, and the stability of grain yield is increased by 10%~20%. As one of the most stable organic matter in soil, humus plays an important role in enhancing soil fertility, improving soil structure, and promoting microbial growth. Over the years, Xinlianxin Group has continuously strengthened enterprise innovation, developed new quality productivity, actively participated in the construction and protection of cultivated land quality, built new ideas, new models, new technologies and new formats of "humic acid +", developed "black" series of products, and created a number of cultivated land field demonstration model fields. Since 2021, the Cultivated Land Quality Monitoring and Protection Center of the Ministry of Agriculture and Rural Affairs has cooperated with Xinlianxin Group to jointly carry out more than 70 experimental demonstrations in 57 counties (cities) in 17 provinces (autonomous regions and municipalities) across the country, covering corn, rice, wheat, soybeans and other food crops. He called on more people in the industry to actively participate in the protection and improvement of cultivated land quality, and make due contributions to national food security and green and high-quality agricultural development.
Cai Shuhong, director of Hebei Provincial Cultivated Land Quality Monitoring and Protection Center
Cai Shuhong, director of the Hebei Provincial Cultivated Land Quality Monitoring and Protection Center, stressed that cultivated land is the foundation of ensuring food security, and strengthening the protection of cultivated land quality is a long-term task and a systematic project. At present, although the fertilizer utilization rate of field crops in Hebei Province has reached more than 40%, the average chemical fertilizer consumption per mu of crops is still at a high level, and the problem of uneven fertilization of different soil types, different regions and different crops is still particularly prominent, and the content of soil organic matter in some areas is still low. A large number of practices have shown that new fertilizers, especially humic acid fertilizers, have good effects on improving the quality of cultivated land, improving fertilizer utilization, promoting crop growth, and improving quality and yield. "Hebei Province has an area of 90.51 million mu of cultivated land, with large volume and great potential for improving the quality of cultivated land.
Zhang Wei, assistant general manager of the fertilizer division of Xinlianxin Group
Zhang Wei, assistant general manager of the fertilizer division of Xinlianxin Group, said that Xinlianxin has always been committed to creating greater value for the society with the least resources, and insisted on the research and development and promotion of high-efficiency fertilizers in the industry. In the future, on the basis of consolidating the original advantages, Xinlianxin Group will continue to increase investment in innovation in products, services and technologies to meet the new needs of the market, create new advantages for the enterprise, lead the new development of the industry, and escort the national food security. Encourage the peasants to increase their incomes and get rich
Guo Jun, director of the Guantao County Agriculture and Rural Bureau
Guo Jun, director of the Guantao County Agriculture and Rural Affairs Bureau, said that Guantao County is located in the middle and lower reaches of the Yellow River, with good water quality and fertile soil, and is a traditional agricultural county. Remarkable results have been achieved in this year's summer grain production, the yield per mu of 100 acres of key fields in Guantao and the surrounding areas has reached about 750 kilograms, and the summer sowing task is 326,000 mu. "This year, there was a drought during the corn sowing period, and there was more rain in the later period, and the yield was affected to varying degrees. But today at the scene, I saw that the corn growth is gratifying and the harvest is in sight, which has a lot to do with the use of the 'dense planting cultivation + efficient fertilizer application' model in the planting method. As an agricultural department, we encourage and welcome all enterprises and scientific research institutes to carry out more research on new technologies and new models, and achieve bumper grain yields, bumper harvests for the people, and quality and efficiency improvement of agriculture through mechanical improvement, optimization of planting models, and reasonable fertilizer formulas. ”
Sun Zhimei, professor and doctoral supervisor of the Department of Plant Nutrition and Fertilizer Science, Hebei Agricultural University
Sun Zhimei, professor and doctoral supervisor of the Department of Plant Nutrition and Fertilizer Science of Hebei Agricultural University, explained the key technologies of high-yield and high-efficiency cultivation of wheat/corn, and emphasized that soil quality and fertilizer and water management are very important by analyzing the production status and problems, and scientific fertilization is very important, and grass pest prevention and control and disease prevention and control must not be ignored. For the winter wheat that is about to be sown, she introduced that the amount of pure nitrogen applied to the bottom fertilizer is 6~8 kg/mu, the amount of phosphorus and potassium is based on the soil fertility situation, the phosphorus of low fertility soil is 6~8 kg/mu, and the potassium is 4~6 kg/mu. Sun Zhimei concluded that the high quality and high yield of crops come from robust growth, and robust growth comes from the strong root system of crops, and strong root system comes from healthy soil, and healthy soil depends on scientific fertilization and tillage management.
Li Renfeng, the developer of the humic acid fertilizer project of the Product Research Institute of Xinlianxin Group
Li Renfeng, the developer of humic acid fertilizer project of Xinlianxin Group Product Research Institute, introduced a new high-efficiency humic acid fertilizer, which can promote the formation of soil aggregates, improve the structure of the soil, make the soil aerated and permeable, and improve the biochemical effect of plant chlorophyll, promote the early germination of crop seeds, and have a high seedling rate and high crop yield. Zhengnutrient humic acid ecological fertilizer is a high-end eco-grade compound fertilizer created by Xinlianxin Group by using a variety of high-end technical approaches to combine the nitrogen, phosphorus and potassium macroelements required for crop growth with mineral fulvic acid and medium and trace elements, which has the effect of rooting and promoting bacteria, living soil and strengthening trees, and contains trace elements such as zinc and manganese, etc., with more comprehensive nutrition.
It is understood at the training site that in the demonstration field observed in this activity, 40 kg/mu of positive nutrient element (28-6-8) was applied to the bottom fertilizer, and 40 kg/mu of humic acid (30-5-10) was applied to the bottom fertilizer of the control field, and the sowing amount, fertilizer amount and management method were the same. In accordance with the requirements of the production measurement, the experts were divided into 3 groups to lead the team to randomly select 3 sampling points with uniform growth in the demonstration project and the control field, and obtained the yield of this test through scientific sampling and production measurement method. The results showed that the yield of maize per mu in the demonstration field was 722.56 kg, and that in the control field was 617.87 kg, with an increase of 16.9%.
"With the corn of the positive nutrient element, the straw leaf color is still thick green after maturity, the nutrient absorption is good, the later stage is not defertilized, the lower leaves of the corn in the control field are yellow, although an acre of land is more than 20~30 yuan, but the growth and yield have gone up." Faced with this data, Gao Shuquan, the owner of the family planting farm of Guantao Deyuan, is very satisfied.
