On April 7, Lin’an District of Hangzhou City, Zhejiang Province, issued the “Maximum Application Limits for Chemical Fertilizers on Major Crops,” which officially took effect on April 14. The standard sets maximum fertilizer application limits for nine crops, including single-season rice, miniature sweet potatoes, eggplant, bottle gourd, tea trees, peach trees, grapes, Lei bamboo, and Chinese walnuts.
Opening quote: April 7th , Zhejiang Hangzhou City, Province Lin’an District has issued the “ Main Limit Standards for the Quota System of Chemical Fertilizers for Crops , April 14th Officially implemented. This standard establishes maximum permissible limits for chemical fertilizers for nine crops, including single-season rice, miniature sweet potatoes, eggplant, bottle gourd, tea plants, peach trees, grapes, Lei bamboo, and Chinese hickory.
It is understood that the formulation and implementation of this standard are intended to fully put into practice the spirit of the “Opinions on Piloting a Quota System for Agricultural Chemical Fertilizer Inputs,” issued in 2019 by the Zhejiang Provincial Department of Agriculture and Rural Affairs and the Provincial Department of Finance (hereinafter referred to as the “Opinions”). According to the Opinions, 2020 In the year, Zhejiang will… Across the entire province, the county-wide implementation of a fertilizer quota system is being advanced. . In 2022, Comprehensive across the entire province Establish a quota system for fertilizer inputs in major crops, with the use of chemical fertilizers (nitrogen fertilizers) reduced compared to 2018 levels. 5%。
Zhejiang’s implementation plan clearly sets the tone for the future technological and product directions of agricultural fertilization nationwide. Next, More provinces, municipalities, and regions, as well as a greater variety of crops, are subject to fertilizer-use restrictions.
“Setting a maximum fertilizer application rate per mu is a true test of the nutrient-use efficiency of the product and the quality of the application techniques, as well as a rigorous evaluation of the processes, R&D capabilities, and equipment of all fertilizer manufacturers.”
In the future, low‑end, inefficient conventional fertilizers will lose their market foothold, while green, high‑efficiency new‑generation fertilizers will gain widespread acceptance.
With rice For example:
This standard specifies single-season rice. The maximum application rates for fertilization are shown in the table below:

According to This standard, according to Common fertilizers Content conversion Per mu of land Application No more than 6 0 kilograms fertilizer. However, in the middle and lower reaches of the Yangtze River Rice–wheat rotation district ， According to farmers’ fertilization practices Habit, Base fertilizer for rice in a single season and A total of fertilization is required. 80 Over kilograms of the Fertilizer 。
According to statistics , our country Rice Fertilization The average utilization rate is 27 %-35% 。 In the future, as fertilizer application increases… Restrictions, Tradition The fertilizer is insufficient to meet yield requirements.
The “Opinions on Piloting a Quota System for Agricultural Chemical Fertilizer Inputs,” issued by the Zhejiang Provincial Department of Agriculture and Rural Affairs and the Provincial Department of Finance, propose that… ， Reducing chemical fertilizer use through nutrient substitution. From the perspective of nutrient substitution, measures such as promoting organic fertilizers, returning straw to the field, planting green manure crops, increasing the application of new‑type fertilizers, and innovating cropping systems should be implemented to strengthen the replacement of chemical fertilizers with organic nutrients, thereby achieving a reduction in chemical fertilizer inputs. For cash crops, priority should be given to the use of organic fertilizers (including bio‑organic fertilizers). ) , organic-inorganic compound fertilizers, water-soluble fertilizers, and others. For grain and oilseed crops, priority should be given to the promotion of formulated fertilizers and organic-inorganic compound fertilizers, Slow (control) ) New types of fertilizers, such as slow-release fertilizers . Vigorously promote the rotation of vegetables and rice, as well as fruit (tea)… - Green manure, rice - Fish ( Shrimp, softshell turtle ) Adopt integrated crop‑livestock farming systems and implement year-round nutrient management for farmland soils to achieve a substantial reduction in fertilizer use.
Satisfy Yield can still be increased within the dosage limit. ----Super-Formulated Controlled-Release Rice Fertilizer
Shandong Agricultural University Fertilizer Technology Co., Ltd. Research and development of the “Super Formula” Controlled-release fertilizer for rice "Is in" Based on fourth-generation coated‑release fertilizer with blue‑film technology ， Combine unique to Four-level activated humic acid , resulting in a two-tiered intelligent controlled-release system. The first tier involves the blue‑film‑based controlled release of inorganic nutrients, significantly… Reduce nutrients Leaching; the second stage involves black‑intelligence control, which locks inorganic nutrients from soil and fertilizers, converting them into organic forms.
“ Super Formula Controlled-release fertilizer for rice "Contains" Various controlled-release fertilizers, blue-film controlled-release fertilizer ， Different release periods meet the nutrient requirements of rice at each growth stage. . Blue film Controlled-release fertilizer In the soil, it absorbs water vapor and dissolves fertilizers, forming a nutrient solution. Once the crop roots take up and consume the nutrients in the rhizosphere, the fertilizer system rapidly senses changes in soil nutrient concentrations and moisture levels, and uses osmotic pressure to release the nutrient solution through nanoscale micropores. Furthermore, ， Black The particles contain Active humic acid is Natural Active organic substances, It can, through chelation, bind the substances in the soil and… In the fertilizer The nutrients are firmly held, with one end adsorbed onto soil particles and the other end oriented toward the crop roots, forming a “soil particle”… - Organic matter - The “nutrient” chain. Two core technologies Products, compounded in proportion, Add Anti-floatation technology, for Rice Custom-made. Therefore ， Agricultural University’s “Super-formula rice controlled-release fertilizer” ” Having The following characteristics:
1. Precise controlled release , phased Release Peak , meet the needs of rice cultivation Fertilizer requirement Regularity, enhancing nutrient uptake Utilization efficiency , reduce the number of topdressing applications, and save labor. Time-saving;
2. Active humic acid Buffering Acid and base , neutralize the fertilizer, improve the soil, and enhance its aggregate structure. , increase Breathability, reduction Root system Poisoning ；
3. Strong roots Stunting, Promote Root growth, enhance Nutrient , water absorption efficiency, and growth regulation, Enhance resistance Inverse property ；
4. Unique Its anti‑floating technology ensures that the fertilizer sinks immediately upon contact with water, making it well suited to the unique conditions of paddy fields.
5. Product Performance
