Abstract

The invention discloses a green fertilizer application method for reducing chemical weight and increasing efficiency in wheat and maize rotation cycle, which comprises the following steps: the suitable wheat-maize rotation variety is selected; the wheat-maize rotation is collocation and the rotation is carried out; wheat and corn stalk full returning to the field is carried out during the rotationperiod. During the rotation, the number of wheat and maize fertilizing times is changed from 4-6 times to 2 times, greatly simplifying the times of fertilizing, realizing the agronomical integrationof agricultural machinery and achieving the realistic goal of freeing the labor force. The technical measures such as humic acid synergism, the whole amount of straw and the substitution of organic fertilizer, reduce the amount of nitrogen and phosphorus fertilizer, and realize the green fertilization and green control of the wheat-maize rotation cycle. The method provides an effective solution for the scientific fertilization of wheat-maize rotation cycle, the improvement of fertilizer utilization rate and the cultivation of cultivated land, which has a high practical value and wide market prospect.

Description

technical field [0001] The invention relates to a green fertilization method for reducing the amount and increasing the efficiency of chemical fertilizers in wheat and corn rotation cycles, and belongs to the technical fields of agricultural technology, humic acid fertilizer and its application. Background technique [0002] North China is the main food producing area in my country, and the wheat-corn rotation system is the main food planting method in North China. Both the planting area and the per unit yield level have greatly guaranteed my country's food security. The large amount of chemical fertilizer input in this area has become one of the dependent conditions for sustained high and stable grain production, but it has also brought about problems such as reduced fertilizer efficiency, environmental pollution, and increased production without increasing income. [0003] Fertilizer is the most important part of agricultural production input, which is related to the susta...
