Embodiment 1

[0029] A cultivation method rich in organic chromium water spinach, comprising the following steps:

[0030] a. Seed soaking and accelerating germination: first take water spinach seeds and place them in the sun for 1 day, then soak them in an aqueous solution at room temperature containing 0.1 part of chromium oxalate and 0.3 part of Paecilomyces lilacinus per 100 parts of water by weight for 8 hours, and then take them out Wash it with clear water, then move it into an environment where the temperature is 35° C. and the temperature is 80% for germination. When the water spinach seeds are 65% white, the water spinach seeds must be sown.

[0031] b. Site selection and preparation: select sandy soil with deep soil layer and convenient drainage and irrigation, first plow the land 23cm deep, and then apply 800kg of bio-organic fertilizer, 200kg of oyster shell powder, 300kg of seaweed fertilizer, 30kg of slaked lime, 20kg of plant ash and Jutian per mu. 1kg of aspartic acid is used...

Embodiment 2

[0038] A cultivation method rich in organic chromium water spinach, comprising the following steps:

[0039] a. Seed soaking and accelerating germination: first take water spinach seeds and place them in the sun for 3 days, then soak them in an aqueous solution at room temperature containing 0.6 parts of chromium oxalate and 1.5 parts of Paecilomyces lilacinus per 100 parts of water by weight for 5 hours, and then take them out Wash it with clear water, then move it into an environment with a temperature of 39° C. and a temperature of 90% for germination, and wait for sowing water spinach seeds when 70% of the water spinach seeds are white.

Abstract

The invention relates to the technical field, in particular to a cultivation method for ipomoea aquatica rich in organic chromium. The method includes the following steps of a, seed soaking and pregermination, wherein ipomoea aquatica seeds are put in the sun to be dried, and then soaked with a normal-temperature water solution and pre-germinated; b, land selection and preparation, wherein sandy soil land is selected, base fertilizer is sufficiently applied, and then the land is prepared and beds are formed; c, sowing, wherein the ipomoea aquatica seeds are sown on bed planes, straw is laid on the bed planes, and watering is carried out properly; d, field management, wherein top dressing, weeding and pest control are carried out regularly; e, harvesting, wherein ipomoea aquatica is harvested multiple times, and every time the ipomoea aquatica grows to 26 cm or above, the ipomoea aquatica can be harvested once. According to the cultivation method for the ipomoea aquatica rich in organic chromium, the content of organic chromium in the ipomoea aquatica can be effectively increased, the nutritional value of the ipomoea aquatica is improved, and the planted ipomoea aquatica further has the advantages that leaves are tender, stems are crispy, and the edible taste is good.

Description

【Technical field】 [0001] The invention relates to the technical field, in particular to a cultivation method of water spinach rich in organic chromium. 【Background technique】 [0002] Ipomoea aquatica (Ipomoea aquatica), formerly known as Yongcai, also known as vine rattan vegetable, weed vegetable, macaroni, Chinese cabbage, urn vegetable, empty tube vegetable, bamboo leaf vegetable, is an annual or perennial vine herbaceous plant of Convolvulaceae. It is native to tropical and rainy regions of my country and is suitable for growing in humid regions. It is mainly distributed in Lingnan region and is a green leafy vegetable commonly cultivated in summer and autumn in southern China. It has white trumpet-shaped flowers and is called "water spinach" because the center of the stalk is hollow. Water spinach is sweet, cold, non-toxic, rich in protein, fat, sugar, inorganic salts, niacin, carotene, vitamin B1, B2, vitamin C, etc. Water spinach can be processed into a variety of h...
