Problems solved by technology
Excessive application of chemical fertilizers and insufficient use of organic fertilizers have been common in vegetable production for a long time. Long-term excessive application of chemical fertilizers will seriously pollute the soil ecological environment, resulting in a decrease in soil quality year by year, thereby affecting the growth of crops and threatening the yield and quality of crops. restrict the sustainable development of agriculture

Embodiment
[0016] From November 2018 to August 2019, the tomato planting test of the fertilization method of the present invention was carried out in Chengao Village, Rudong County, Nantong City, Jiangsu Province. The planting process is as follows: figure 1 Shown:
[0017] (1) Plow the land first, apply vermicompost as the base fertilizer on November 6, 2018, and the amount of fertilizer applied is 15t ha -1 ;
[0018] (2) Sow milk vetch on November 7, 2018, the sowing method is broadcasting, and the sowing rate is 30kg ha -1 ;
[0019] (3) On April 25, 2019, the fresh grass of milk vetch in full flowering stage was harvested and crushed, and all the milk vetch was turned and pressed to below 15cm of the plow layer with a rotary tiller;
[0020] (4) One month after overturning and decomposing, nitrogen and phosphorus fertilizers were applied on May 26, 2019, and the local conventional fertilizer amount was 96kgN ha -1 、96kg Pha -1 , the amount of fertilizer applied in this experime...

The invention discloses a fertilizer-reducing and effect-improving fertilizer application method for combined application of green manure and compost. The method comprises the following steps: (1) applying compost in soil in winter; (2) sowing leguminous green manure after application of the compost; (3) turning and pressing the leguminous green manure to the position under the soil of a plough layer in a full-bloom stage so as to allow the leguminous green manure to be decomposed; (4) applying a nitrogen-phosphorus base fertilizer in soil; (5) transplanting vegetable crops; and (6) topdressing a nitrogen fertilizer in the topdressing stage of the vegetable crops. According to the fertilizer application method, the green manure and the compost are combined for usage, so the usage amount ofa traditional chemical fertilizer is reduced, soil health is improved, and the leaching loss of NO3<->-N in soil is reduced by 28.01%; and meanwhile, the yield and quality of crops can be improved, the yield of the crops is increased by 31.35%, and the content of nitrate in the crops is reduced by 9.45%.
Description
technical field [0001] The invention relates to a fertilization method, more specifically, to a weight-loss and synergistic fertilization method using green manure and compost. Background technique [0002] The construction of ecological civilization is the millennium plan for the sustainable development of the Chinese nation. Agriculture is the basic industry of the national economy and has multiple functions such as production, ecology, economy, society, and culture. Therefore, agriculture is an important carrier for the construction of ecological civilization. Green development of agriculture, Sustainable development is the concrete embodiment of the concept of ecological civilization in agriculture, and the construction of ecological civilization will definitely promote the green development of agriculture. Excessive application of chemical fertilizers and insufficient use of organic fertilizers have been common in vegetable production for a long time. Long-term excessiv...
