Planting method of iron-rich summer spinach

Abstract

The invention discloses a planting method of iron-rich summer spinach, comprising the following steps: (1) seed treatment, (2) sowing treatment, (3) sowing post-treatment and (4) spinach harvesting. According to the planting method provided by the invention, stages including seed treatment, temperature and humidity, fertilizer applying and the like are reasonably controlled during spinach planting, the method confirms to a growth natural law of spinach at various stages, and cultured spinach can normally grow at relatively high temperature of 30 to 35 DEG C; compared with the prior art, the yield of the spinach is increased by 25 to 35 percent, the nutrition absorption performance of the spinach is greatly enhanced, the iron element content of the spinach is doubled, the vitamin C content is improved by 30 to 40 percent, the spinach is more fresh and green, and the appearance and shape are better.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a planting method of iron-rich summer spinach. Background technique [0002] Spinach (Spinacia oleracea L.), also known as Persian vegetable, red root vegetable, parrot vegetable, etc., belongs to Chenopodiaceae spinach, an annual herb plant, native to Iran, and widely cultivated in China. It is one of the most common vegetables. Spinach is known as "Nutrition Model Student". It is rich in carotenoids, vitamin C, vitamin K, minerals (calcium, iron, etc.), coenzyme Q10 and other nutrients. Moisturizing effect. It can cure epistaxis, blood in the stool, scurvy, quench one's thirst and induce drinking, and astringent and stagnant stool. Spinach is mostly planted by seeds, and the seeds need to be treated before sowing to improve the germination rate and seedling quality. Spinach is a vegetable that is not resistant to heat and strong light. If the temperature exceeds 25°C, it ...

AI Technical Summary

Problems solved by technology

Spinach is a vegetable that is not resistant to heat and strong light. If the temperature exceeds 25°C, it will grow poorly. However, if this problem can be overcome and it can still be cultivated efficiently in summer, then plant it in June to July. It will be on the market in September, which will generate higher economic benefits. However, the existing methods of growing spinach in summer usually require a large amount of shading and cooling operations with high energy consumption, which will undoubtedly increase the cost of planting, and the spinach will be exposed to high temperature due to irresistible factors. environment, will bring greater damage to the growers, in addition, the yield and quality of the summer spinach produced by the existing method can not reach the desired effect
