Embodiment 1

[0050] Embodiment 1: Traditional cultivation scheme, fertilizer application

[0051] Under the conditions of the traditional cultivation scheme, the specific treatment of Chinese cabbage cultivation is as follows:

[0052] Step (1), sowing and germination: After the cabbage seeds are selected, they are sown in the substrate tray and germinated. After 5-7 days, all the seeds emerge, and when they grow to 2 leaves and 1 heart, pour water once every 2-3 days.

[0053] Step (2), soil preparation and application of basal fertilizer: select a field with flat terrain, convenient drainage and irrigation, and fertile soil as a field for cabbage cultivation. After the soil is leveled, apply 40 kg of compound fertilizer per mu, spread evenly on the soil, and make furrows with a width of 1.2-1.6 meters and a height of 20-25 centimeters, in the shape of a turtle's back.

[0054] Step (3), timely transplanting: when the cabbage seedlings grow to 4 leaves and 1 heart, fully moisten the mat...

Embodiment 2

[0059] Embodiment 2: sea fertilizer application

[0060] Using seaweed extract and seaweed water-soluble fertilizer, the specific steps of cultivating Chinese cabbage are as follows:

[0061] Step (1), sowing and germination: After the cabbage seeds are selected, they are sown in the substrate tray and germinated. After 5-7 days, all the seeds emerge, and when the cabbage heart grows to 2 leaves and 1 heart, apply clear water once every 2-3 days.

[0062] Step (2), soil preparation and application of basal fertilizer: select a field with flat terrain, convenient drainage and irrigation, and fertile soil as a field for cabbage cultivation. After the soil is leveled, apply 100 kg of fully decomposed organic fertilizer and 25 kg of compound fertilizer per mu, spread evenly on the surface of the soil, and then make a furrow with a width of 1.2-1.6 meters and a height of 20-25 cm, which is turtle-shaped.

[0063] Step (3), timely transplanting: when the Chinese cabbage seedlings ...

Embodiment 3

[0068] Embodiment 3: sea fertilizer+amino acid calcium magnesium

[0069] In embodiment 3, utilize seaweed extract, seaweed water-soluble fertilizer and amino acid calcium magnesium fertilizer containing choline chloride, in the specific steps of cultivating Chinese cabbage, steps (2), (5), (6), (7) All identical with embodiment 2, only step (1), (3), (4) are different, specifically as follows:

[0070] (1), sowing and germination: After the cabbage seeds are selected, they are sown in the substrate tray and germinated. After 5-7 days, all the seeds emerge, and when the cabbage heart grows to 2 leaves and 1 heart, spray the seaweed extract once every 2-3 days.

[0071] (3), timely transplanting: the cabbage seedlings grow in the substrate tray for 13-15 days, when the cabbage seedlings grow to 4 leaves and 1 heart, after 5 o'clock in the afternoon on a sunny day, select strong seedlings and transplant in good time. When transplanting, cut off the 2-3mm root tip of the main r...

Abstract

The invention discloses a flowering cabbage planting method for improving edible quality and slowing down lignification of tender stems. According to the method, flowering cabbages are subjected to spraying application or root spraying with a seaweed extract once every 3-4 days when two leaves and one heart grow on each flowering cabbage; the flowering cabbages are transplanted to a large field when four leaves and one heart grow on each flowering cabbage; during transplanting, 2-3 mm root tips of main roots of the flowering cabbages are cut off by using a sterilized blade, and then the flowering cabbages are soaked in a seaweed extract for 5 minutes and transplanted into the soil; after seedling recovery, spraying application or root spraying is conducted with seaweed water-soluble fertilizer once every 4 days; 1 week before bolting of the flowering cabbages, spraying application or root spraying is conducted on the flowering cabbages with a choline chloride and amino acid calcium magnesium solution once every 4 days, and application is conducted once 1 day before harvesting. Compared with traditional cultivation, the contents of soluble protein, soluble sugar and vitamin C of theleaves of the flowering cabbages produced by means of the method are increased by 8.2-15.9%, 8.1-11.3% and 9.1-11.7% respectively, the content of crude fibers is decreased by 10.8-16.5%, and the occurrence rate of the lignification of the tender stems is decreased by 52.7%.

Description

technical field [0001] The invention belongs to the technical field of vegetable cultivation, and in particular relates to a cabbage planting method for improving edible quality and slowing lignification of tender stems. Background technique [0002] Caixin, also known as vegetable sprouts, is known as the "crown of vegetables" and is the vegetable crop with the largest cultivated area in Guangdong Province. Choi Sum of good quality is the main vegetable variety sold in Hong Kong, Macao, Europe and the United States. [0003] The root system of Chinese cabbage is underdeveloped and the distribution is shallow. At the same time, the cultivation density is high and the growth rate is fast. Therefore, the cultivation technology of Chinese cabbage is very important. The cultivation methods and fertilization of Chinese cabbage significantly affect the yield and quality of Chinese cabbage. [0004] Literature reports: The edible part of Chinese cabbage contains 13-18 grams of pr...
