Abstract

The invention discloses a soil fertilizer supply index in potato high-yield cultivation and a determination method, and belongs to the technical field of agriculture, rural areas, and farmers. The method comprises the following steps: S1, detecting soil: obtaining a soil sample for detection, and analyzing soil components; S2, formulating a special formula, which includes: S2-1, establishing a potato fertilization index system, S2-2, establishing a soil nutrient abundance and deficiency index and fertilization index system, S2-3, obtaining a soil nutrient abundance and deficiency index, S2-4,establishing a fertilization index system, and S2-5, recommending a potato fertilization index; S3: producing a formula fertilizer; S4, supplying the formula fertilizer; and S5: demonstrating and promoting. According to the index and method, the traditional fertilization concept of farmers is changed, the implementation of agricultural cost-saving, efficiency-increasing, soil-testing and formulated fertilization technologies is promoted, the soil structure is improved, the soil fertility is improved, the quality of agricultural products is improved, and the non-point source pollution caused byexcessive fertilization or improper fertilization is reduced, so that the ecological environment is greatly improved.

Description

technical field [0001] The invention relates to the technical field of agriculture, rural areas and farmers, in particular to soil fertilizer supply index and measuring method in high-yield potato cultivation. Background technique [0002] Improve the availability rate, coverage rate and fertilizer utilization rate of scientific fertilization technology, and gradually build a fertilizer production, management, promotion and supervision system and mechanism suitable for the development of the potato industry. The key is to propose different soils and different varieties of organic fertilizers before potato sowing. , the application quantity, application ratio, application period, and supporting application techniques of large, medium, and trace element fertilizers to achieve the goal of "replenish what is lacking, and do not waste when you are full". [0003] Therefore, the index and determination method of soil fertilizer supply in high-yield potato cultivation are provided....
