Problems solved by technology

[0003] In the process of rice seedling cultivation without soil, the nitrogen content and zinc content in the nutrient solution have a very important impact on the normal growth of the seedlings. When the nitrogen content in the nutrient solution is insufficient, the leaves of the seedlings usually turn yellow; When the zinc content in the solution is insufficient, it will lead to the appearance of red seedlings or stiff seedlings; and the above two situations will cause the seedlings to not grow healthily in the later stage
[0004] But, in the related art, the nitrogen content and the zinc content in this commonly used nutrient solution are all relatively low; Seedlings do not grow healthily in later stages

Abstract

The invention relates to the field of soilless rice nursery, and particularly relates to a nutrient solution for rice and a producing method thereof. The nutrient solution for rice comprises a first nutrient solution and a second nutrient solution in a given volume ratio, wherein the first nutrient solution per liter comprises the following effective components in parts by weight: 2-3 parts of NH4NO3, 1-1.5 parts of NaH2PO4.2H2O, 1.8-2.5 parts of K2SO4, 3-3.5 parts of CaCl2, 8-9 parts of MgCl2, and 3-4 parts of (NH4)2SO4; the volume ratio of the first nutrient solution to the second nutrient solution is (750-850): 1. The nitrogen content and zinc content of the nutrient solution disclosed by the invention are relatively high, so that the phenomena of yellow leaves, red seedlings and runt seedlings of rice shoots at the later stage because the nitrogen content and zinc content of a nutrient solution in the prior art are insufficient are avoided, and then the rice shoots can grow healthily and strongly at the later stage.

Description

technical field [0001] The invention relates to the field of soilless seedling raising of rice, in particular to a rice nutrient solution and a preparation method thereof. Background technique [0002] In the field of rice seedling cultivation without soil, the nutrient supply of rice seedlings is completely dependent on the nutrient solution. In related technologies, the nutrient solution formula of the International Rice Institute is generally adopted now. [0003] In the process of rice seedling cultivation without soil, the nitrogen content and zinc content in the nutrient solution have a very important impact on the normal growth of the seedlings. When the nitrogen content in the nutrient solution is insufficient, the leaves of the seedlings usually turn yellow; When the zinc content in the liquid is insufficient, it will lead to the appearance of red seedlings or stiff seedlings; and the above two situations will cause the seedlings to not grow healthily in the later s...
