Abstract

The invention discloses a vegetable field soil phosphorus supply force lifting method based on vegetable chemical phosphate fertilizer reduced application. The method comprises the following steps: setting vegetable field soil phosphorus supply level I, and correspondingly setting the total phosphorus recommendation quantity of an applied phosphorus fertilizer in a planting season according to thevegetable field soil phosphorus supply level I and vegetable variety; detecting the phosphorus supply value of current vegetable field soil and comparing with the vegetable field soil phosphorus supply level I to obtain a vegetable field soil phosphorus supply level II, and then obtaining the total phosphorus recommendation quantity of the applied phosphorus fertilizer corresponding to the current vegetable field soil phosphorus supply level II; calculating the applied amount of the phosphorus fertilizer with different phosphorus sources according to the obtained total phosphorus recommendation quantity of the applied phosphorus fertilizer; and applying the phosphorus fertilizer for current vegetable according to the applied amount of the phosphorus fertilizer and vegetable variety. According to the method, the content of labile phosphorus base composition is effectively increased while the medium and higher yield level in vegetable is guaranteed, the soil phosphorus supply force of vegetable fields is improved, the soil environment is improved, and sustainable utilization of phosphate rock resources is maintained.

Description

technical field [0001] The invention relates to the technical field of vegetable planting, in particular to a method for improving the phosphorus supply capacity of vegetable field soil based on reducing the application of chemical phosphorus fertilizers for vegetables. Background technique [0002] China is a big vegetable producing country. In 2013, my country's vegetable production accounted for 51.3% of the world's total, ranking first. The vegetable industry is one of the pillar industries of agricultural production in Hebei Province. In 2015, the province’s vegetable planting area was 1.242 million hectares, and the vegetable output reached 82.437 million tons, ranking second in the country. In recent years, the production of protected vegetables in Hebei Province has developed rapidly. In 2015, the output of protected vegetables reached 27.333 million tons, accounting for 33.1% of the vegetable production in the province. Facility vegetable production has become an i...
