Simplified seedling raising substrate for date palm tillering seedlings and preparation method thereof

Abstract

The invention discloses a simplified seedling raising substrate for date palm tillering seedlings and a preparation method thereof. The simplified seedling raising substrate comprises a reagent A, a reagent B and a reagent C. The reagent A is a 1/4 MS salt solution containing carbendazim diluted by 800-1200 times and azoxystrobin diluted by 800-1200 times; the reagent B is a mixed solution containing a naphthylacetic acid solution with the concentration of 300 to 600 mg/L, an indolebutyric acid solution with the concentration of 100 to 200 mg/L and a 2, 4-dichlorphenoxyacetic acid solution with the concentration of 50 to 100 mg/L; the volume ratio of the naphthylacetic acid solution to the indolebutyric acid solution to the 2, 4-dichlorphenoxyacetic acid solution is 2: 1: 1.5; the reagent C is a naphthylacetic acid solution with the concentration of 0.3 to 0.7 mg/L. The substrate further comprises a fixed substrate B and a rooting substrate C; wherein the rooting substrate C comprises the following components in percentage by volume: 65%-75% of decomposed coconut residuums, 7%-15% of perlite, 5%-10% of organic fertilizer, 7%-15% of vermiculite and 0.1%-0.4% of slow release fertilizer. According to the substrate, the date palm tillering seedlings are subjected to in-vitro culture by adopting an external intervention method, rooting culture is promoted, and the functions of resisting diseases, preventing insects, promoting wound repair, accelerating rooting, ensuring sufficient nutrients, improving the survival rate, being easy to load, transport and plant and the like are achieved.

Description

technical field [0001] The invention relates to the field of plant biotechnology, and more specifically relates to a light and simplified seedling-raising substrate for jujube tillering seedlings and a preparation method thereof. Background technique [0002] The date palm tree (scientific name: Phoenix dactylifera L.) belongs to the genus of Palmaceae. It is native to the desert oasis of North Africa or the surrounding areas of the Persian Gulf in southwestern Asia. It is one of the four earliest domesticated and cultivated fruit trees by humans. It is currently in my country Hainan, Fujian, Guangxi, Yunnan, Guangdong and other tropical and subtropical regions are planted. The date palm, the fruit of the date palm tree, is rich in nutritional value, with a sugar content as high as 55%-70%, a protein content of 3%, and a variety of amino acids. It is also one of the main grains of the Arabs. [0003] Date palm is a dioecious perennial crop, and the traits of the seedlings ar...
