Embodiment 1

[0023] A kind of propagation method utilizing stem section callus to cultivate chayote, the steps are as follows:

[0024] 1) Seed selection: choose fat, undamaged, and fully mature chayote as the seed melon;

[0025] 2) Seedling cultivation: put the seedling substrate in the seedling tray, water it to 65% of the soil saturation, and plant the melon in the seedling tray in the middle and early November, with the top of the melon facing up and 4cm away from the tray surface, and cover it with the seedling substrate Flush with the surface of the plate, cover the surface with a layer of straw, put it in the greenhouse, and control the temperature of the greenhouse at 22-25°C;

[0026] The seedling-raising substrate is composed of the following raw materials in parts by weight: 25 parts of humus soil, 18 parts of garden soil, 2 parts of egg shells, 8 parts of dry animal manure, 3 parts of coconut bran, 2 parts of Panax notoginseng medicine dregs, and 0.8 parts of tea leaves , 7 s...

Embodiment 2

[0034] A kind of propagation method utilizing stem section callus to cultivate chayote, the steps are as follows:

[0035] 1) Seed selection: choose fat, undamaged, and fully mature chayote as the seed melon;

[0036] 2) Seedling cultivation: put the seedling substrate in the seedling tray, water it to 60% of the soil saturation, and plant the melon in the seedling tray in mid-to-early November, with the top of the melon facing up and 4.5cm away from the tray surface, and use the seedling substrate The covering is flush with the surface of the plate, and the surface is covered with a layer of straw, put into the greenhouse, and the temperature of the greenhouse is controlled at 22-25°C;

[0037] The seedling-raising substrate is composed of the following raw materials in parts by weight: 24 parts of humus soil, 17 parts of garden soil, 1.5 parts of egg shells, 7 parts of dry animal manure, 3.5 parts of coconut bran, 1.5 parts of Panax notoginseng medicine dregs, and 0.5 parts ...

Embodiment 3

[0045] A kind of propagation method utilizing stem section callus to cultivate chayote, the steps are as follows:

[0046] 1) Seed selection: choose fat, undamaged, and fully mature chayote as the seed melon;

Abstract

The invention provides a propagation method for cultivating chayote by utilizing stem segment callus, relating to the technical field of vegetable cultivation. The method comprises the following steps: selecting seeds, raising seedlings, strengthening the seedlings, taking stem segments, propagating and cutting. According to the method disclosed by the invention, propagation cultivation is performed by utilizing the stem segment callus of the chayote, the induction rate is high, the callus formation rate can reach 70% or higher, the propagation coefficient is effectively increased, the cost is reduced, and the yield of the chayote is improved. Moreover, the survival rate of cuttings can reach 86% or higher, and an effective way is provided for establishing chayote tissue cultivation and propagation.

Description

technical field [0001] The invention relates to the technical field of vegetable planting, in particular to a propagation method for cultivating chayote by using stem section callus. Background technique [0002] Chayote (scientific name: Sechium edule), also known as Falcon melon, An pumpkin, Shou melon, Harvest melon, Yang melon, Heshou melon, Holding melon, etc., is a plant of the Cucurbitaceae Chayote genus, native to Mexico, China. The Americas and the West Indies were introduced to China in 1915 and are planted in the Jiangnan area of ​​China, with the most in Yunnan, Zhejiang, Fujian, Guangdong, and Taiwan. Chayote is crisp and packed with nutrients. Each kilogram of fresh melon contains 5 grams of protein, 1 gram of fat, 30 grams of cellulose, and 77 grams of carbohydrates. It also contains 220 mg of vitamin C, 0.1 mg of riboflavin, 500 mg of calcium, 320 mg of phosphorus, and 40 mg of iron. Chayote can be used as a vegetable or eaten raw as a fruit. In addition, ...
