Abstract

The invention discloses a formula of a potato nutrient solution. The formula comprises the following components in parts by weight: 395-440mg / L of urea, 560-620mg / L of diammonium phosphate, 410-470mg / L of monopotassium phosphate, 660-720mg / L of potassium sulfate, 480-530mg / L of magnesium sulfate, 5-9mg / L of ethylenediaminetetraacetic acid ferric sodium salt, 1.5-3mg / L of manganese sulfate, 1.2-2mg / L of zinc sulfate, 2-2.8mg / L of boric acid, 0.1-0.4mg / L of copper sulfate and 0.1-0.35mg / L of sodium molybdate. The formula disclosed by the invention is reasonable, urea, diammonium phosphate, monopotassium phosphate, potassium sulfate, magnesium sulfate, ethylenediaminetetraacetic acid ferric sodium salt, manganese sulfate, zinc sulfate, boric acid, copper sulfate and sodium molybdate are comprehensively utilized, the utilization degrees of the components of the nutrient solution are increased, the nutrient components of the formula are sufficiently matched, and the formula is applicable togrowth of potatoes; due to mutual matching of the components of the formula, nutrients required by growth of the potatoes are provided; by adjusting the ratio of the components of the nutrient solution, the growth requirements of the potatoes can be very well met, and the formula is very well applicable to growth of the potatoes.

Description

technical field [0001] The invention belongs to the technical field of nutrient solution, in particular to a potato nutrient solution formula. Background technique [0002] The existing potato growth has the following problems: the nutrient availability of the nutrients in the first nutrient solution is not high; the mutual cooperation of the nutrients in the second nutrient solution cannot meet the needs of potatoes, that is, the unreasonable design of the potato nutrient solution formula causes the nutrient solution It cannot be well matched with the growth of potatoes, the growth rate is slow, and there are many deformities in the growth shape, which cannot produce better economic benefits. Contents of the invention [0003] The purpose of the invention is to provide a potato nutrient solution formula with high bioavailability of nutrients in the nutrient solution and reasonable formula design. [0004] In order to solve the above problems, the present invention provid...
