Expansion of knowledge:
Wheat is an annual or perennial herbaceous plant in the family Gramineae, genus Wheat, with erect, tufted culms up to 100 centimeters tall, leaf sheaths loosely wrapped around the stems, and ligules membranous, with long lanceolate leaf blades. Spike erect, spikelets containing many florets, glumes ovoid, lemmas oblong-lanceolate, palea and lemma several times as long. Flowering and fruiting May-July.
It is widely cultivated throughout north and south China, and there are many varieties, all with different traits. The caryopsis of wheat is one of the staple foods of mankind, and when ground into flour it can be made into bread, buns, cookies, noodles, and other foods, and when fermented it can be made into beer, alcohol, liquor (such as vodka), or biomass fuel.
Culms erect, tufted, with 6-7 nodes, 60-100 cm tall, diameter 5-7 mm. Leaf sheaths loosely wrapped, lower ones longer than upper ones shorter than internodes; ligule membranous, ca. 1 mm; leaf blades long lanceolate. Spikes erect, 5-10 cm long (except awns), 1-1.5 cm wide; spikelets containing 3-9 florets, upper ones rudimentary.
Glumes ovoid, 6-8 mm, main veins ridged distally on back, extending into teeth ca. 1 mm at tip, dorsal ridges of lateral veins and apical teeth inconspicuous; lemmas oblong-lanceolate, 8-10 mm, apically awned or awnless; palea and lemma several times as long.
The soil is deep and well-structured with a deeper tillage layer, which is conducive to water retention and fertilizer retention, and promotes root development. Soil structure refers to the proportion of solid (organic and inorganic), liquid, gas composition, which has a close relationship with soil moisture, air, temperature, nutrients, such as sandy soils, heavy clay soil structure is poor, it is difficult to form a high yield.
Winter varieties of the appropriate average daily temperature of 16 ~ 18 ℃, semi-winter for 14 ~ 16 ℃, spring for 12 ~ 14 ℃. The temperature of the air is affected by geographical latitude and altitude, that is, the higher the latitude and altitude, the lower the temperature, the seeding period can be earlier.
