Introduction
Corn is China's largest food crop, and high yield and stable yield of corn is essential to ensure China's food production. With the scale of corn production
The expansion of chemicalization and the continuous improvement of mechanization require the standardization and light reduction of corn production. At the same time, there is fertilization in China's corn production.
Non-standard, excessive application, serious nutrient loss, and non-point source pollution also require the scientific and standardized corn fertilization. To achieve China's jade
This standard is specially formulated for the production of precision fertilization, standardized fertilization, cost-effectiveness and environmental friendliness.
Corn Single Fertilization Technical Guide
1 Scope
This standard gives the fertilizer type, nutrient application rate and proportion, fertilizer nutrient release period, fertilization time,
Technical guidelines for fertilization depth, spacing of seed fertilizers, and associated agricultural machinery operations.
This standard applies to the main corn producing areas of the country, and other corn growing areas can be used as a reference.
This standard does not apply to sandy soils and other soils with poor water retention and fertilizer retention.
