Abstract

The invention concretely relates to a water and fertilizer integration fertigation method for tomatoes, aiming at solving the problems that existing organic fertilizer application has nutrient waste and causes environmental pollution, and the crop yield and quality are influenced due to the unreasonable formula of an organic fertilizer. The method comprises the steps of a. before planting, applying phosphorus, nitrogen and potassium; and b. applying organic-inorganic mixed fertilizers during drop irrigation every 5-7 days at the seedling stage, medium period and later period, wherein the organic-inorganic mixed fertilizer per liter applied at the seedling stage is formed by the following components by concentration: 105-115g of urea, 35-45g of potassium dihydrogen phosphate, 240-260g of biochemical fulvic acid potassium and 480-520g of chicken manure liquid, the organic-inorganic mixed fertilizer per liter applied at the medium period contains 125-135g of urea and 85-95g of potassium dihydrogen phosphate, the organic-inorganic mixed fertilizer per liter applied at the later period contains 85-95g of urea and 70-80g of potassium dihydrogen phosphate, and the content of biochemical fulvic acid potassium and chicken manure liquid at the medium period and the later period is equal to that of biochemical fulvic acid potassium and chicken manure liquid at the seedling stage. After the method is used, the available nutrient of the organic fertilizer can be accurately conveyed into the root zones of plants at any time, and the fertilizer efficiency exerting way of the organic fertilizer is changed.

Description

technical field [0001] The invention relates to crop fertilization technology, in particular to a tomato water and fertilizer integrated drip irrigation and fertilization method. Background technique [0002] Excessive application of chemical fertilizers in crop production leads to the decline of crop product quality, poor taste, deterioration of soil texture, pollution of groundwater resources and other disadvantages, which have long been widely recognized by people. Therefore, there is a kind of erroneous thinking that "the more organic fertilizer is applied, the better" in production. Especially in vegetable production, chicken manure, as one of the most common organic fertilizer sources, is usually used as a base fertilizer for excessive, concentrated, and incompletely decomposed and applied at one time. Because it has not been factory-processed and standardized, it not only has a bad smell, but also a large amount of nutrients are slowly released after being applied in...
