biographical notes
Spinach of Chenopodiaceae is an annual or biennial herb. Also known as spinach and Persian grass. Use leaves and tender stems as food. Originally from Persia, it was cultivated 2000 years ago. Later, it spread to North Africa, and from the Moors to Western Europe, Spain and other countries. Spinach was introduced into the Tang Dynasty in 647.
Spinach has developed taproot, red fleshy root and sweet and edible taste. Root groups are mainly distributed in the soil surface layer of 25 ~ 30 cm. The leaves are clustered, and the petiole is inserted on the short stem disk before bolting, which is rosette-like and dark green. The unisexual flowers are dioecious, the sex ratio is about 1: 1, and occasionally monoecious. Male flowers are spikes or panicles, and female flowers are clustered in leaf axils. Fruit, each containing 1 seed, with hard leathery shell. According to the structure of fruit bracts, it can be divided into two kinds: spiny species and spinless species. Spinach is a cold-tolerant vegetable and a long-day plant. It needs more water in its growth process, and it grows vigorously when the effective water content of soil is 70% ~ 80% and the relative humidity of air is 80% ~ 90%. The requirements for soil are not strict, and pH 7 ~ 8 is appropriate. The demand for nitrogen fertilizer is more, followed by phosphorus fertilizer and potassium fertilizer. Sowing can be done in spring and autumn. Autumn sowing is the main growth period, about 60 days. In northern China, there are also plants that plant in winter and harvest in spring, commonly known as burying their heads in spinach. Drilling or broadcasting can be used. The main diseases of spinach are downy mildew, virus disease and anthracnose, and the main pests are aphids and liriomyza sativae.
Spinach stems and leaves are soft, tender and delicious, and are rich in minerals such as vitamin C, carotene, protein, iron, calcium and phosphorus. Besides fresh vegetables, it can also be dehydrated, dried and frozen.
Spinach contains a lot of beta carotene and iron, and it is also an excellent source of vitamin B6, folic acid, iron and potassium. Among them, rich iron can improve iron deficiency anemia and make people look rosy and radiant, so it is known as a beauty product. Spinach leaves contain chromium and an insulin-like substance, which is very similar to insulin and can keep blood sugar stable. Rich B vitamins can prevent the occurrence of vitamin deficiency such as angular stomatitis and night blindness. Spinach contains a lot of antioxidants, such as vitamin E and selenium, which can resist aging and promote cell proliferation. It can not only activate brain function, but also enhance youthful vitality, which helps to prevent brain aging and Alzheimer's disease. A study by Harvard University also found that middle-aged and elderly people who eat spinach 2-4 times a week can reduce the risk of retinal degeneration by taking vitamin A and carotene, thus protecting their eyesight.

[Edit this paragraph] Planting
First, sowing date and variety
Autumn spinach. Sow in August-September, and harvest in batches 30-40 days after sowing. Early maturing and heat-resistant varieties should be selected, such as plowshare, Huabo 1, Guangdong round leaf, spring and autumn big leaf, etc.
Overwintering spinach was sown in early October of10-165438+10, and harvested in batches around the Spring Festival. It is advisable to choose mid-late maturity varieties with strong winterness, late bolting and strong cold tolerance, such as round leaf pineapple, late leaf pineapple, Huabo 1, Liaoning round leaf pineapple, etc.
Spinach in spring When the temperature rises above 5℃ in spring, sowing can begin. The suitable sowing time is March, and the harvest can be achieved 30-50 days after sowing. Late bolting, big leaf in spring and autumn, round leaf in Shenyang and round leaf in Liaoning should be selected.
Summer spinach. Sow in stages from May to July, and harvest in late June to mid-September. Huabo 1, Chunqiu Daye and Guangdong Round Leaf with strong heat resistance, fast growth and difficult bolting should be selected.
Second, land preparation and border preparation.
Choose loose and fertile loam with water and fertilizer conservation, good irrigation and drainage conditions and good acidity, and the PH value is 5.5-7. When preparing soil, apply 4000 kg of decomposed organic fertilizer and 40 kg of calcium superphosphate per mu, and make it smooth and delicate. It is advisable to make a high border in winter and spring, and a flat border in summer and autumn, with a border width of1.2-1.5m..
Third, sow and raise seedlings.
Generally, broadcasting is adopted. Summer and autumn sowing is 1 week before sowing. After soaking seeds in water for 12 hours, put them in a well or a refrigerator or freezer at about 4℃ for 24 hours, then accelerate germination at 20-25℃, and sow after germination for 3-5 days. Dry seeds or wet seeds can be sown in winter and spring. Sow 3-3.5 kilograms per mu.
After watering the bottom of the bed, sow the seeds, lightly rake the topsoil with a toothed rake and sow the seeds into the soil, and cover the bed with a layer of plant ash.
After sowing in summer and autumn, cover the sunshade net with straw or a small arch shed to prevent high temperature and heavy rain from washing away. Keep the soil moist often, and the seedlings can grow together in 6-7 days. If the winter sowing temperature is low, cover the border with plastic film or sunshade net to keep warm and promote seedling emergence, and remove it after seedling emergence.
Fourth, on-site management
After the spinach leaves fall in autumn, it should be watered with 1 times cleaning water; After two true leaves, combine thinning, weeding and topdressing, first light and then thick, and apply more decomposed manure in the early stage; Topdressing 2-3 times in peak period, using 5- 10 kg urea per mu.
After sowing spinach in winter, the soil remains moist. When planting 3-4 real leaves, water should be properly controlled to facilitate overwintering. When there are 2-3 true leaves, the seedling spacing is 3-4 cm. According to the emergence situation and weather, topdressing water and fertilizer, mainly decomposed human feces. Frost and snow weather should be covered with plastic film and sunshade net, which can be covered with a small arch shed. After the beginning of spring, choose sunny days to topdressing decomposed light fertilizer to prevent early bolting.
In the early stage of spring, spinach should be covered with plastic film for heat preservation, which can be directly covered on the frame. After emergence, the film should be uncovered or a small arch shed should be built. The small arch shed should cover the night and rain, so that the seedlings can see more light, harden more seedlings and interplant in time. Topdressing and water, lightly applying decomposed human and animal manure in the early stage, and applying quick-acting nitrogen fertilizer in the later stage, especially before harvest 15 days.
After the emergence of summer spinach, it is still necessary to cover the sun-shading net, cover it well, cover it early and uncover it early, so as to facilitate cooling and heat preservation. Watering at seedling stage should be done in the morning or evening. After 2-3 real leaves, topdressing with quick-acting nitrogen fertilizer twice. Water every time after fertilization to promote growth.
Five, pest control
Aphids are sprayed with 40% dimethoate 1000 times solution or 50% pirimicarb 2000-3000 times solution; Spraying 50% phoxim EC or 80% trichlorfon powder 1000 times to liriomyza sativae; Downy mildew is sprayed with 58% carbendazim 500 times solution or 75% chlorothalonil 600 times solution; Anthracnose was controlled by spraying 500 times of 50% thiophanate methyl or 700 times of 50% carbendazim.
Sixth, timely harvest
Generally, when the seedling height is greater than 10 cm, it can be harvested in batches. Spraying 15-20 mg/kg of 92O on the leaves before one-time harvesting, and adding urea or ammonium sulfate can lead to early harvesting and increase yield.
Seven, seeds.
The sowing date of reserve spinach can be a little later than that of overwintering spinach. Drill, row spacing 20-23 cm. After turning green in spring, the miscellaneous plants and early bolting male plants are pulled out one after another, leaving some nutritious male plants, so that the spacing between plants is about 20 cm. It is not advisable to irrigate more water at bolting stage to avoid weak flowers lodging and reduce seed yield. After flowering, topdressing, irrigation and foliar spraying 1%-2% calcium superphosphate clear solution will make the seeds full. After the male plants are seeded, unplug the male plants for ventilation and light transmission. Most of the stems and leaves are yellow, and the seeds are harvested when they are mature, and threshed for a few days after maturity.
[Edit this paragraph] Pest control
The main disease is downy mildew of spinach.
1. Symptoms mainly harm leaves, with light green spots at first, inconspicuous edges and nearly round to irregular expansion. White mold grows on the back of leaves, then turns purple-gray, and withers and rots in severe cases.
