Embodiment Construction

[0022] The substantive content of the present invention will be specifically described below in conjunction with the embodiments, but those skilled in the art should know that the protection scope of the present invention should not be limited to these specific embodiments.

[0023] 1. Experimental materials

[0024] Galantamine, epigalantamine, Lycosinine A, Lycosinine B, manjuline, lycorine, dihydrolycorine, narciscine purchased or homemade, with a purity of not less than 95%. The chemical structural formula is shown in the table below.

[0025]

[0026] 2. Experimental method

[0027] 1. Planting of cassava seedlings

[0028] The cassava SC8 variety (namely Huanan No. 8, sensitive to drought) with a diameter of about 2 cm and a length of about 10 cm was used to plant in a plastic flowerpot with a diameter of 26 cm, a bottom diameter of 16 cm, and a height of 23 cm. Fill the pot with sun-dried vermiculite and sand at a ratio of 1:1 (V:V). Weigh the flower pot (W1) in ...

Abstract

The invention discloses application of a manihot esculenta crantz MeTPS1-3 gene expression activator in preparing fertilizer for enhancing the drought resistance of manihot esculenta crantz. As known,expression of MeTPS1-3 can be irritably added by the manihot esculenta crantz under a drought situation, so that resistance to drought stress can be increased. The invention discovers that after intervention of galantamine and epi-galantamine is given, the expression of the MeTPS1-3 is remarkably and further increased, and meanwhile, the resistance to the drought stress is remarkably enhanced, sothat the galantamine and the epi-galantamine can be used for preparing the fertilizer capable of increasing the drought resistance of the manihot esculenta crantz. Fertilizer additives or fertilizerpreparation ingredients can also be added in the fertilizer, the fertilizer additives can be human and animal excreta, and the fertilizer preparation ingredients can be pulverized fuel ash, plant ash,bentonite, kaolin, attapulgite clay or plant straw.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to the application of a cassava MeTPS1-3 gene expression activator in preparing fertilizers for enhancing the drought resistance of cassava. Background technique [0002] Cassava (Manihot esculenta Crantz) is recognized as an economic crop with high comprehensive utilization value and an important industrial raw material. Cassava suffers from long-term drought, especially at the seedling stage, which will lead to a sharp decline in cassava yield. Studying the molecular mechanism of cassava drought resistance can not only improve the drought resistance of cassava varieties, but also provide a reference for the drought resistance research of other crops. [0003] In recent years, in the study of plant stress resistance, trehalose synthase gene is another kind of gene closely related to stress resistance after glutamic acid, proline, and betaine synthase genes, which has aroused...
