Fertilizer applying method for reducing fertilizer application and improving fertilizer effect in soybean-corn rotation system

Abstract

The invention discloses a fertilizer applying method for reducing the fertilizer application and improving the fertilizer effect in a soybean-corn rotation system. The fertilizer applying method comprises the following steps of: (S1) detecting the water content in planting soil, and adjusting times, frequency and time of sprinkling irrigation according to a detection result; (S2) digging plantingholes, paving modified base soil, base fertilizer and a mixture of the base fertilizer and wood dust, and planting and curing crops according to a conventional method; (S3) regularly applying composite organic fertilizer A to the planting soil in the growth process of the crops, applying composite organic fertilizer B to the planting soil of the crops when the crops grow to a flowering period, increasing fertilizer applying frequency, and restoring use of the composite organic fertilizer A for application when the crops grow to a manure period and restoring the original fertilizer applying frequency. The fertilizer applying method disclosed by the invention has the beneficial effects that water and nutrients needed for the crops are ensured, the absorption efficiency of the crops is high,the growth speed is fast, the growth period is short, the yield is high, the chemical fertilizer use amount is less and the use frequency is low, so that the fertilizer applying method is especially suitable for the northeast region of China.

Description

Technical field [0001] The invention relates to the technical field of agricultural products planting, and in particular to a fertilization method for reducing chemical fertilizer application and increasing efficiency in a soybean-corn rotation system. Background technique [0002] Corn is one of the main food crops in my country, it is a high-quality feed and industrial raw material for the development of animal husbandry, and it is also one of the main crops in Northeast China. The planting time of corn in the Northeast is usually in mid-to-late April, and the time of receiving the goods is usually in early October. During this period, due to the influence of climatic conditions in the northeast, droughts often occur, resulting in serious water shortages in the corn planted and affecting corn The growth of corn has reduced the yield of corn. As another important agricultural product in Northeast China, soybean is the ideal companion for corn rotation. Reasonable crop rotation ...

AI Technical Summary

Problems solved by technology

However, the crop rotation effect of corn and soybean in Northeast China is not satisfactory at present. The reason is that apart from environmental factors such as drought, the long-term application of chemical fertilizers is also the main factor.

Long-term application of chemical fertilizers will lead to soil compaction, soil acidification, and nutrient imbalance in the soil, which will eventually affect the health of corn and soybean users through the food chain
