In the early spring of greenhouses, the cucumber-enhanced close-growing cultivation method is a new type of cucumber cultivation technology that increases planting and total production through the cultivation of high-alfalfa plants. First, nursery. Cucumber seedlings in early spring 40-50 days, should be sown in early February. After seeding, the management of seedbeds should be strengthened. The temperature should be controlled at 25-30°C during the day and 20-25°C at night, and the temperature should be appropriately reduced after emergence. The main line cucumber grafted seedlings. 3 leaves 1 heart started seedling exercise, and sprayed on the seedbed 1 times 75% of dexamethasone 500 times liquid to prevent disease, and then colonized. Second, colonization. Colonization is the key to this technology. A large greenhouse with a small shed covered with grass and sheds should be planted in mid-March in the middle of March; a large shed with a small shed outside the sheds should be planted in late March. The main points are: 1 row of late-maturing varieties of high-sorghum planted one line of short-early early-maturing varieties, or through a topping control dwarfing. The planting method used small sorghum, which had a width of 60 cm and a pod spacing of 30 cm. The sorghum planted one line of sorghum and one line of dwarf sorghum. The same height, height and height are 40 centimeters apart, sorghum plant spacing is 20 centimeters, dwarf sorghum plant spacing is 30 centimeters, sorghum sorghum or short sorghum row is 90 centimeters, total density is about 6100 plants per mu, and strives for sunny morning planting, and high ground temperature planted in the afternoon. Note that the small sorghum first opened a hole on the water, a small amount of water, seedlings into the water after the cover soil, avoid pouring water. Third, pre-management. 1, slow seedlings. After the planting, the shed was kept at 30°C during the day, 15°C at night, and the soil temperature was 12°C. The temperature in the shed could not exceed 35°C. When the seedlings begin to fade (the faucet leaves become lighter), proper ventilation can be used to reduce the temperature and maintain the temperature of 25°C-28°C during the day and about 15°C at night. The ventilation of greenhouses and small arches should alternate. 2, Shun Man and tied vines. Before the roots were harvested, the membranes of the small arches were lifted and the direction of the vines was staggered. Remove the small arch shed around the end of April, use the wire rack top and pull down the plastic rope to tie the vines, and pay attention to the position of the leading leaves of the same plant. Fences are also available, but only half is used. 3, fertilizer watering. After the root melon sat, fertilizer and water were applied in time, and after the second melon sat, the long-fertilizer should be applied. It is best to use the bean cake. 4, timely harvest root melon. It usually takes about 10 days from flowering to harvesting. In order not to affect the growth of vines and the satiety rate of the second and third pods, root pods should be harvested in time. Fourth, Guagua period management. 1, greenhouse temperature control. During the day, the shelf temperature is maintained at 25°C-28°C, the relative humidity of the air should be below 80%, the temperature at night should be 13°C-15°C, the relative humidity should be below 90%, and the ground temperature should be 20°C-25°C. If the temperature is high during the day, ventilation should be timely and the grass should be covered at night when the temperature is low. 2, fertilizer and water management. Cucumber from the melon to pull vines need dressing 3 to 5 times, each time required to apply NPK fertilizer compound 8-10 kg. To prevent later defermentation, foliar spraying with 1% urea and 0.3% potassium dihydrogen phosphate solution is also possible. In the early stage, the temperature of the ground water should be less, and the ground temperature can be watered once in 3-4 days. During the fruiting period, the soil must see dry and wet to ensure that the melon grows straight. The proper performance of the water supply is: the head is not curled straight, the tendrils are less curved, and the leaves are not dark green. Fifth, rational adjustment of plants. The emphasis of cucumbers for dense planting is the control of high and low larvae. Add 2-3 cucumbers per cucumber to the top of the leaves when it appears. When the second and third fruits are harvested, they must be removed from the cucumber vines. At this time, the cucumbers of the main line are growing at a time. The vines should be tied in time, and tendrils, old leaves, and diseased leaves should be removed. When the main line of cucumber vines grow to the top of the roof, when the leaves reach 25-26 pieces topping, this will be beneficial to knot the head melon. Six, pest control 1, physical control. Set yellow traps to kill whitefly, aphids, and adults of Liriomyza sativae. 2, biological control. Use 1% agricultural anti-wuyimycin 150-300 times liquid or Telek 600-800 times liquid to control powdery mildew, downy mildew, etc.; use 1.8% awesome clear 4000 times liquid to control spider mites, aphids and so on. 3, chemical control. Cucumber powdery mildew can be controlled by 20% triadimefon 500 times; downy mildew can be controlled by 300 times spray of aluminum alginate.
Hormone & Endocrine
Hormone:
A chemical
substance produced in the body that controls and regulates the activity of
certain cells or organs. Many hormones are secreted by special glands, such as
thyroid hormone produced by the thyroid gland. Hormones are essential for every
activity of life, including the processes of digestion, metabolism, growth,
reproduction, and mood control. Many hormones, such as neurotransmitters, are
active in more than one physical process.
Endocrine:
Pertaining to
hormones and the glands that make and secrete them into the bloodstream through
which they travel to affect distant organs. The endocrine sites include the
hypothalamus, pituitary gland, pineal gland, thyroid, parathyroids, heart
(which makes atrial-natriuretic peptide), the stomach and intestines, islets of
Langerhans in the pancreas, the adrenal glands, the kidney (which makes renin,
erythropoietin, and calcitriol), fat cells (which make leptin). the testes, the
ovarian follicle (estrogens) and the corpus luteum in the ovary). Endocrine is
as opposed to exocrine. (The exocrine glands include the salivary glands, sweat
glands and glands within the gastrointestinal tract.)
