Embodiment 1

[0023] 1. Preparation of a calcium-containing growth regulator (calcium regulator):

[0024] Take 0.5g NAA, 0.5g IBA, 0.2g ZT, mix, dissolve with a small amount of ethanol and dilute to 1L, prepare the mother liquor of root irrigation agent for later use, store in low temperature under shading, or use it as it is prepared, when in use, take the root irrigation agent Mother liquor 10ml and Ca(NO 3 ) 2 2g was dissolved in 10L of water to make root irrigation;

[0025] Take 2g of ABA, dissolve it with a small amount of ethanol and dilute it to 1L, and make it into a spraying agent mother liquor for later use. When in use, take 5ml of the spraying agent mother liquor, 25g of urea, KH 2 PO 4 5g was dissolved in 5L of water to prepare a spraying agent.

[0026] 2. The use of calcium regulators:

[0027] Take the purple leaf dwarf cherry transplanted in Tianjin Binhai New Area as an example.

[0028] The ground diameter of purple leaf dwarf cherry is 7-8cm, and the whole crown ...

Embodiment 2

[0035] 1. Preparation of a calcium-containing growth regulator (calcium regulator):

[0036]Take 0.3g NAA, 0.3g IBA, 0.2g ZT, mix, dissolve with a small amount of ethanol and dilute to 1L, prepare the mother liquor of root irrigation agent for later use, store it under low temperature in shading, or use it as it is prepared.

Abstract

The invention relates to calcic growth regulator used for seeding transplantation in a saline area. The calcic growth regulator comprises a root-irrigation agent and a spraying agent. The root-irrigation agent comprises the components of naphthylacetic acid, indolebutyric acid, Ca(NO3)2 and zeatin. The spraying agent comprises the components of abscisic acid, urea and KH2PO4. The calcic regulator is used for the seedling transplantation in the coastal saline area, and can obviously improve a seedling survival rate. A result of a transplanting experiment implemented on pruns x cistenenas and Chinese ashes in the Tianjin Binhai New Area Taida Plant Resource Library from May to December in 2012 shows that the calcic growth regulator can improve the survival rate of the pruns x cistenenas from 12% to 90% and can improve the survival rate of the Chinese ash trees from 50% to 90%, the content of physiological active calcium, the content of chlorophyll and the content of soluble sugar in a plant body are improved obviously, and the content of malonaldehyde is lowered significantly.

Description

technical field [0001] The invention relates to a growth regulator, in particular to a calcium-containing growth regulator (calcium regulator) for transplanting seedlings in saline-alkali areas. Background technique [0002] Calcium is an essential macronutrient for plants and plays an important role in growth, development and plant stress resistance. It can stabilize the cell wall structure, maintain the permeability of the plasma membrane, regulate growth and development, mediate signal transduction, combine with secondary metabolites to detoxify, etc. In the low-humidity saline-alkaline environment, Ca 2+ deficit, while H + -ATPase is produced by Ca 2+ regulated, so leads to H + - The activity of ATPase decreases, the selectivity to ions decreases, and a large amount of Na+ flows into cells, causing damage to plants. Therefore, the application of exogenous calcium can significantly reduce the absorption of Na + and the transportation to stems and leaves of plants, and...
