Problems solved by technology

[0003] However, due to the extensive use of chemical fertilizers in rice cultivation, the pesticide residues in the soil exceed the standard, and at the same time, the ecological environment of the soil is destroyed, the soil fertility is reduced, and the phenomenon of farmland soil pollution and water pollution is not uncommon.
In recent years, food safety issues have occurred frequently. Vegetables, as the main food that people cannot do without in daily life, have not been spared. Various pesticides have not been applied according to national or industry standards. Excessive application of pesticides has caused serious pesticide residues in vegetables, endangering food consumption. health and even life safety

Embodiment 1

[0018] Example 1 Effects of Different Nitrogen Fertilizer Application Patterns on Rice Nutrient Absorption and Yield

[0019] In the monitoring base of the embodiment of the present invention, two consecutive years of field positioning tests were carried out, and 4 kinds of nitrogen fertilization patterns were set: (1) CK: control (no nitrogen fertilizer); (2) T1: 100% nitrogen fertilizer (100% traditional chemical fertilizer N) (3) T2: 20% nitrogen fertilizer reduction mode; (4) T3: nitrogen fertilizer: organic nitrogen fertilizer = 3:5 (30% nitrogen fertilizer + 50% organic nitrogen) that is: on the basis of 20% nitrogen fertilizer reduction, traditional chemical fertilizer nitrogen and The ratio of nitrogen content in straw organic fertilizer was 3:5. The fertilization methods are shown in Table 1, and the nitrogen uptake and yield of crops under different nitrogen fertilization treatments were measured.

[0023] Example 2 Effects of Different Nitrogen Fertilizer Application Patterns on Soil Organic Matter

[0024] In the monitoring base of the embodiment of the present invention, two consecutive years of field positioning tests were carried out, and 4 kinds of nitrogen fertilization patterns were set: (1) CK: control (no nitrogen fertilizer); (2) T1: 100% nitrogen fertilizer (100% traditional chemical fertilizer N) (3) T2: 20% nitrogen fertilizer reduction mode; (4) T3: nitrogen fertilizer: organic nitrogen fertilizer = 3:5 (30% nitrogen fertilizer + 50% organic nitrogen) that is: on the basis of 20% nitrogen fertilizer reduction, traditional chemical fertilizer nitrogen and The ratio of nitrogen content in straw organic fertilizer was 3:5. The fertilization methods are shown in Table 1, and the soil organic matter of different nitrogen fertilizer application patterns was determined.

[0025] The result is as image 3 It was shown that compared with the control, the treatment...

[0026] Soil bacteria, actinomycetes, fungus quantity under different fertilization patterns of embodiment 3

[0027] In the monitoring base of the embodiment of the present invention, two consecutive years of field positioning tests were carried out, and 4 kinds of nitrogen fertilization patterns were set: (1) CK: control (no nitrogen fertilizer); (2) T1: 100% nitrogen fertilizer (100% traditional chemical fertilizer N) (3) T2: 20% nitrogen fertilizer reduction mode; (4) T3: nitrogen fertilizer: organic nitrogen fertilizer = 3:5 (30% nitrogen fertilizer + 50% organic nitrogen) that is: on the basis of 20% nitrogen fertilizer reduction, traditional chemical fertilizer nitrogen and The ratio of nitrogen content in straw organic fertilizer was 3:5. Fertilization methods are shown in Table 1, and the number of soil bacteria, actinomycetes, and fungi in different nitrogen fertilizer application patterns were determined.

[0028] The result is as Figure 4 As shown, the test resul...

Abstract

The invention discloses a fertilization method for a crop rotation planting mode of rice and vegetables. A replacement mode of reducing 20% nitrogen fertilizer and replacing the reduced nitrogen fertilizer with straw organic nitrogen fertilizer is adopted. Combination of straw returning and application of the chemical fertilizer is carried out, the application amount of the chemical fertilizer canbe effectively reduced, environmental pollution caused by excessive application of chemical fertilizer and straw burning is prevented, the ecological environment of soil is improved, and the net income of farmers is increased. Moreover, the use amount of chemical fertilizer is reduced, the soil fertility is improved, the soil nutrients are supplemented and balanced, the soil is improved, the resource utilization rate is increased, the cost is saved, the efficiency is improved, the stable yield, high yield and high efficiency of agriculture are achieved, and ecological, social and economic comprehensive benefits are brought. By adopting the fertilization method, the yield of rice is increased by 35%.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a fertilization method for a rice-vegetable rotation planting mode. Background technique [0002] For a long time, the issue of food security has always been the top priority of people's livelihood. In order to increase food production, the rice-vegetable rotation model has been vigorously developed in recent years, introducing crops that can improve economic benefits into rice field production. On the premise of ensuring stable food production, through The development of characteristic economic crops improves the economic benefits per unit area, forms a relatively stable industrial development model, and realizes the double increase of money and food. [0003] However, due to the extensive use of chemical fertilizers in rice cultivation, the pesticide residues in the soil exceed the standard, and at the same time, the ecological environment of the soil is destr...
