Problems solved by technology

In this patent, the selenium-enriched nutrient mixture is sprayed on the water spinach, which can increase the selenium content of the water spinach to a certain extent, but due to the addition of the selenium nutrient solution alone, the water spinach has a limited absorption and conversion rate of selenium, resulting in the final selenium content of the water spinach. Still not high, and the method of this patent can not reduce the nitrate content in water spinach

Embodiment 1

[0035] The water spinach hydroponic method of the present embodiment, comprises the steps:

[0036] (1) Seed screening: select water spinach seeds with full grains and smooth surface and a shelf life of no more than one year, rinse with clean water to remove dust and impurities, and remove broken and shriveled seeds at the same time;

[0037] (2) Seed treatment: the screened seeds were heat-shocked at 55°C for 25 minutes, and then quickly put the seeds into 1% H 2 o 2 Soak in the solution for 24 hours;

[0038] (3) Accelerating germination: pick up the treated seeds, wash them with clean water, and use clean water to rinse and accelerate the germination of water spinach seeds in a germination accelerating room at 20°C, once every 8 hours;

[0039] (4) Substrate preparation: Mix 1800 kg of decomposed organic fertilizer and 80 kg of plant ash into each mu of soil; and pile it into a furrow with a height of 25 cm and a width of 100 cm;

[0040] (5) Sowing: Sow when the seeds a...

Abstract

The invention discloses a water planting method for water spinach. The method comprises the steps of seed screening, seed heat shocking-soaking treatment in an H2O2 solution, drip washing by adoptingclean water for germination treatment, sowing, pruning, segmented dilution for water planting and the like. According to the method, dual-treatment of seed heat shocking-soaking treatment in the H2O2solution is adopted for improving the vigor of seeds of water spinach, shortening the germination period and increasing the germination rate; according to the development characteristics of water spinach in the water planting process, the segmented dilution for water planting is adopted for promoting increasing of biomass, the growing period of water spinach is short, the water planting space is fully utilized, and the vegetable yield is increased; the water planting method for water spinach can be applied to culturing of four seasons and suitable for large-scale production; a suitable amountof sodium selenite, methionine and isoleucine is added into a nutrient solution, the content of selenium in water spinach can be improved, and the content of nitrate and nitrite in water spinach is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, and in particular provides a hydroponics method for water spinach. Background technique [0002] Water spinach (Ipomoea aquatica Forsk), also known as macaroni because of the hollow internodes, is an annual or perennial vine herb of the genus Sweetpotato in the family Convolvulaceae. Its stems and leaves are rich in vitamins and mineral elements, and are resistant to waterlogging, light, and high temperature. They are extremely important leafy vegetables in high temperature seasons in summer. [0003] The protein content in the tender shoots of water spinach is 4 times higher than that of tomatoes of the same amount, the calcium content is more than 12 times higher than that of tomatoes, and it contains more carotene, which has high nutritional value. The niacin and vitamin C contained in spinach can lower cholesterol and triglycerides, and have the effect of reducing fat and lo...
