Embodiment Construction

[0023] The present invention will be further described below in conjunction with specific embodiments.

[0024] The active substance in the special formula fertilizer in the fresh table grape full course combination drip irrigation fertilizer of the present invention is provided by following material respectively: nitrogen (N): urea; Phosphorus pentoxide (P 2 o 5 ): diammonium phosphate; potassium oxide (K 2 O): Potassium sulfate.

[0025] The specific formula of the whole combination drip irrigation fertilizer for table grapes corresponding to different growth stages in the growth and development of the above grapes is as follows:

[0026] The optimal percentage by weight of fertilizer A in terms of pure nutrients is: nitrogen (N) 15%, phosphorus pentoxide (P 2 o 5 )15%, potassium oxide (K 2 O) 26%, the balance is excipient; And the sum of total nutrient weight percent is N+P 2 o 5 +K 2 O=56%. The physical amount converted into commercial fertilizer is selected from ...

Abstract

The invention relates to a fresh grape overall-process combination drip irrigation fertilizer. The water-soluble fertilizer is transferred to the grape root region by the drip irrigation technique according to different demands for nutrients in the grape growth development process. The drip irrigation fertilizer comprises a fertilizer used in the grape sprouting period, a fertilizer used in the grape blooming and fruit-setting period, a fertilizer used in the grape fruit expansion period, a fertilizer used in the grape pulp period, and a fertilizer used after harvest. By combining the drip irrigation technique, the fresh grape overall-process combination drip irrigation fertilizer enhances the fertilizer utilization ratio, reduces the waste of irrigation water, and improves the quality of the water-soluble fertilizer and the compatibility between fertilizer application and grapevine nutrient demands.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a water-saving and efficiency-enhancing fertilizer for fresh table grape combined drip irrigation throughout the whole process. Background technique [0002] Grape is one of the four major fruits in the world. According to FAO statistics, in 2008, the world's vineyard planting area was 7.408 million hectares 2 , accounting for 12.3% of the total fruit planting area, is the fruit with the largest planting area in the world, and its output ranks fourth in the world's fruits. my country's grape industry is developing very rapidly. At the end of 2013, the grape production reached 11.55 million tons, and the planting area reached 714,600 hm 2 , becoming the world's second largest main producer of grapes, second only to Italy in output. However, due to the long-term cultivation of fruit farmers relying on experience, one-sided pursuit of yield, backward technology and the phenome...
