Growth process of soybean
Seedling emergence:
The life of soybean goes through the process of seed germination, seedling emergence, seedling growth, branching, flowering, podding, bulging and maturity. It can be divided into six reproductive periods. The radicle first extends from the ovule bead hole, and when the radicle elongates to the same length as the seed, it is called germination. When the embryonic axis elongates, the seed coat falls off, and the cotyledons are exposed to the soil surface along with the hypocotyl, and when the cotyledons unfold, it is called seedling emergence. The conditions are suitable, 4-6 days after sowing the seedling can emerge.
Seedling stage:
Seedling stage is from seedling to flower bud differentiation. After the emergence of seedlings, 2 cotyledons unfolded, its young stem continues to elongate, above the 2 opposite single leaves then unfolded, this time is called the single-leaf period. As the young stem continues to elongate, the first compound leaf is called the 3-leaf stage. 3-leaf stage above ground part of the growth rate is slower, the underground root system grows faster to form rhizomes. At the end of this period, the root system is initially formed and begins to require more water and nutrients. The seedling period is about 20-25 days, accounting for l/5 of the entire reproductive period.
Flowering and podding period:
From the beginning to the end of the flower for the flowering period, from the soft and small pods appeared to the formation of young pods for the podding period, out of the soybean flowering and podding is in parallel, so that these two periods are commonly known as the flowering and podding period. Soybean flower is very small, bearing in the leaf axil or the top of the stem, the number of flowers bearing on each flower cluster, depending on the variety and cultivation conditions. Soybeans have a high rate of flower and pod drop, so the number of pods per flower cluster is low. Soybeans bloom at 6-9 a.m., and the period from bud to bloom is generally 3-7 days.
After fertilization of the ovule, the ovary gradually expands to form soft and small green pods, which are called pods when they are lcm long. The growth of pods is first growth, then widening, and finally thickening. The flowering and podding period is the most vigorous period of soybean fertility, is the period that requires the most water and nutrients, and at the same time requires sufficient light. On the basis of the pre-seedling full, seedling strong, branching more, the flowering period should strengthen the fertilizer management, and make good permeability, in order to achieve the requirements of more flowers, more English, more grains and reduce the shedding of flowers and English.
Maturity:
Leaf blade by yellow off the road, beans dehydration, showing varieties of intrinsic traits, when the seed water content has fallen to less than 15%, until shaking the plant in the English have a slight ringing, that is, the maturity of the period. At this time should reduce soil moisture, accelerate seed and plant drying, to facilitate timely harvesting, while preventing excessive fertilizer caused by greedy green late maturity, affecting timely harvesting and stubble. This period of sunny and dry weather can promote maturity and help improve quality.
Definition:
The scientific name for soybeans is soybean. Soybean is an annual herbaceous plant of the genus Soybean of the family Leguminosae, loess production in China. China has been cultivated since ancient times, so far there have been 5000 years of cultivation history. Now the country is widely planted, in the northeast, north China, Shaanxi, Sichuan and the lower reaches of the Yangtze River are produced to the Yangtze River Basin and southwest of the cultivation of more, to the northeast of the soybean quality is optimal. Soybean is rich in isoflavones, can cut off the nutritional supply of cancer cells, containing essential 8 kinds of amino acids, a variety of vitamins and a variety of trace elements, can reduce blood cholesterol, prevention of hypertension, coronary heart disease, hardening of the animal, can be cosmetic and so on. Soybean contains linoleic acid, can promote children's neurodevelopment. Soybeans can be processed into tofu, soy milk, soy sauce or curd.
Introduction:
Basic Introduction
Cultivated soybeans are scientifically known as Giycine max (L) Merrill, alias: soybeans (including green, black, purple, and speckled chayote, etc.), and in English alias: Soybean. Soybean, rich in protein, originated in China, which is recognized by scholars around the world. Herbert in the Encyclopedia Americana pointed out that: "Ancient Chinese literature suggests that soybeans were widely cultivated for their high nutritional value before they were documented. At the same time soybeans were recognized as the most important legume in 2000 BC." [2]
Taxonomy
Soybean is an annual herbaceous plant of the genus Soybean in the family Leguminosae.
Traits
Soybean, also known as soybean, is a favorite food. Soybeans and the various kinds of soybean products processed by people with it are common delicious dishes on the table. Soybeans are not only delicious, but also has a high nutritional value. 500 grams of soybean protein content is equivalent to 1500 grams of eggs, or 6000 grams of milk, or 1,000 grams of lean pork. In addition, the fat content of soybeans in the beans in the first place, the oil rate of up to 20%, and rich in a variety of vitamins and minerals. Therefore, soybean is known as the "king of beans".
The soybean does not contain cholesterol, and can reduce human cholesterol, reduce the occurrence of atherosclerosis, prevention of heart disease, soybean also contains a pancreatic enzyme inhibiting substances, it has a certain effect on diabetes. Therefore, soybeans are recommended by nutritionists for the prevention and treatment of coronary heart disease, hypertension, atherosclerosis and other diseases of the ideal health products. Soft phospholipids contained in soybeans are an important part of the composition of brain cells, often eat soybeans to increase and improve brain skills have an important effect.
Nutritional structure
According to scientific determination, every 100 grams of soybean contains:
Calcium: 191 (mg), phosphorus: 465 (mg), potassium: 1503 (mg), sodium: 2.2 (mg), magnesium: 199 (mg), iron: 8.2 (mg), zinc: 3.34 (mg), selenium: 6.16 (micrograms), manganese: 2.26 ( mg), Iodine: 9.7 (mg), Thiamine: 0.41 (mcg), Riboflavin: 0.2 (mg), Niacin: 2.1 (mg), Vitamin E(T): 18.9 (mg), Vitamin A: 37 (mg), Carotene: 220 (mg), Water: 10.2 (g), Calories: 359 (kcal), Energy: 1502 (kJ), Protein : 35 (g) Fat: 16 (g), Carbohydrates: 34.2 (g), Dietary Fiber: 15.5 (g), Ash: 4.6 (g)[3]
Storage Methods
Before storing, you should dry the soybeans in the sun, and then put in the right amount of cereal bugs net. Contraindications
